  1. General SEO information
    1. History of search engines

In the early days of Internet development, its users were a privileged minority and the amount of available information was relatively small. Access was mainly restricted to employees of various universities and laboratories who used it to access scientific information. In those days, the problem of finding information on the Internet was not nearly as critical as it is now.

Site directories were one of the first methods used to facilitate access to information resources on the network. Links to these resources were grouped by topic. Yahoo was the first project of this kind opened in April 1994. As the number of sites in the Yahoo directory inexorably increased, the developers of Yahoo made the directory searchable. Of course, it was not a search engine in its true form because searching was limited to those resources who’s listings were put into the directory. It did not actively seek out resources and the concept of seo was yet to arrive.

Such link directories have been used extensively in the past, but nowadays they have lost much of their popularity. The reason is simple – even modern directories with lots of resources only provide information on a tiny fraction of the Internet.

The WebCrawler project started in 1994 and was the first full-featured search engine. The Lycos and AltaVista search engines appeared in 1995 and for many years Alta Vista was the major player in this field.

In 1997 Sergey Brin and Larry Page created Google as a research project at Stanford University. Google is now the most popular search engine in the world.

Currently, there are three leading international search engines – Google, Yahoo and MSN Search. They each have their own databases and search algorithms. Many other search engines use results originating from these three major search engines and the same seo expertise can be applied to all of them. For example, the AOL search engine ( uses the Google database while AltaVista, Lycos and AllTheWeb all use the Yahoo database.

    1. Common search engine principles

To understand seo you need to be aware of the architecture of search engines. They all contain the following main components:

Specific implementations of search mechanisms may differ. For example, the Spider+Crawler+Indexer component group might be implemented as a single program that downloads web pages, analyzes them and then uses their links to find new resources. However, the components listed are inherent to all search engines and the seo principles are the same.

Spider – This program downloads web pages just like a web browser. The difference is that a browser displays the information presented on each page (text, graphics, etc.) while a spider does not have any visual components and works directly with the underlying HTML code of the page. You may already know that there is an option in standard web browsers to view source HTML code.

Crawler – This program finds all links on each page. Its task is to determine where the spider should go either by evaluating the links or according to a predefined list of addresses. The crawler follows these links and tries to find documents not already known to the search engine.

Indexer – This component parses each page and analyzes the various elements, such as text, headers, structural or stylistic features, special HTML tags, etc.

Database – This is the storage area for the data that the search engine downloads and analyzes. Sometimes it is called the index of the search engine.

Results Engine – The results engine ranks pages. It determines which pages best match a user’s query and in what order the pages should be listed. This is done according to the ranking algorithms of the search engine. It follows that page rank is a valuable and interesting property and any seo specialist is most interested in it when trying to improve his site search results. In this article, we will discuss the seo factors that influence page rank in some detail.

Web server – The search engine web server usually contains a HTML page with an input field where the user can specify the search query he or she is interested in. The web server is also responsible for displaying search results to the user in the form of an HTML page.

  1. Internal ranking factors

Several factors influence the position of a site in the search results. They can be divided into external and internal ranking factors. Internal ranking factors are those that are controlled by seo aware website owners (text, layout, etc.) and will be described next.

    1. Web page layout factors relevant to seo
      1. Amount of text on a page

A page consisting of just a few sentences is less likely to get to the top of a search engine list. Search engines favor sites that have high information content. Generally, you should try to increase the text content of your site in the interest of seo. The optimum page size is 500-3000 words (or 2000 to 20,000 characters).

Search engine visibility is increased as the amount of page text increases due to the increased likelihood of occasional and accidental search queries causing it to be listed. This factor sometimes results in a large number of visitors.

      1. Number of keywords on a page

Keywords must be used at least three to four times in the page text. The upper limit depends on the overall page size – the larger the page, the more keyword repetitions can be made. Keyword phrases (word combinations consisting of several keywords) are worth a separate mention. The best seo results are observed when a keyword phrase is used several times in the text with all keywords in the phrase arranged in exactly the same order. In addition, all of the words from the phrase should be used separately several times in the remaining text. There should also be some difference (dispersion) in the number of entries for each of these repeated words.

Let us take an example. Suppose we optimize a page for the phrase “seo software” (one of our seo keywords for this site) It would be good to use the phrase “seo software” in the text 10 times, the word “seo” 7 times elsewhere in the text and the word “software” 5 times. The numbers here are for illustration only, but they show the general seo idea quite well.

      1. Location of keywords on a page

A very short rule for seo experts – the closer a keyword or keyword phrase is to the beginning of a document, the more significant it becomes for the search engine.

      1. Text format and seo

Search engines pay special attention to page text that is highlighted or given special formatting. We recommend:

– use keywords in headings. Headings are text highlighted with the «H» HTML tags. The «h1» and «h2» tags are most effective. Currently, the use of CSS allows you to redefine the appearance of text highlighted with these tags. This means that «H» tags are used less than nowadays, but are still very important in seo work.;

– Highlight keywords with bold fonts. Do not highlight the entire text! Just highlight each keyword two or three times on the page. Use the «strong» tag for highlighting instead of the more traditional «B» bold tag.

      1. «TITLE» tag

This is one of the most important tags for search engines. Make use of this fact in your seo work. Keywords must be used in the TITLE tag. The link to your site that is normally displayed in search results will contain text derived from the TITLE tag. It functions as a sort of virtual business card for your pages. Often, the TITLE tag text is the first information about your website that the user sees. This is why it should not only contain keywords, but also be informative and attractive. You want the searcher to be tempted to click on your listed link and navigate to your website. As a rule, 50-80 characters from the TITLE tag are displayed in search results and so you should limit the size of the title to this length.

      1. ALT» attributes in images

Any page image has a special optional attribute known as “alternative text.” It is specified using the HTML «ALT» tag. This text will be displayed if the browser fails to download the image or if the browser image display is disabled. Search engines save the value of image ALT attributes when they parse (index) pages, but do not use it to rank search results.

Currently, the Google search engine takes into account text in the ALT attributes of those images that are links to other pages. The ALT attributes of other images are ignored. There is no information regarding other search engines, but we can assume that the situation is similar. We consider that keywords can and should be used in ALT attributes, but this practice is not vital for seo purposes.

      1. Description Meta tag

This is used to specify page descriptions. It does not influence the seo ranking process but it is very important. A lot of search engines (including the largest one – Google) display information from this tag in their search results if this tag is present on a page and if its content matches the content of the page and the search query.

Experience has shown that a high position in search results does not always guarantee large numbers of visitors. For example, if your competitors’ search result description is more attractive than the one for your site then search engine users may choose their resource instead of yours. That is why it is important that your Description Meta tag text be brief, but informative and attractive. It must also contain keywords appropriate to the page.

      1. Keywords Meta tag

This Meta tag was initially used to specify keywords for pages but it is hardly ever used by search engines now. It is often ignored in seo projects. However, it would be advisable to specify this tag just in case there is a revival in its use. The following rule must be observed for this tag: only keywords actually used in the page text must be added to it.

    1. Site structure
      1. Number of pages

The general seo rule is: the more, the better. Increasing the number of pages on your website increases the visibility of the site to search engines. Also, if new information is being constantly added to the site, search engines consider this as development and expansion of the site. This may give additional advantages in ranking. You should periodically publish more information on your site – news, press releases, articles, useful tips, etc.

      1. Navigation menu

As a rule, any site has a navigation menu. Use keywords in menu links, it will give additional seo significance to the pages to which the links refer.

      1. Keywords in page names

Some seo experts consider that using keywords in the name of a HTML page file may have a positive effect on its search result position.

      1. Seo and the Main page

Optimize the main page of your site (domain name, index.html) for word combinations that are most important. This page is most likely to get to the top of search engine lists. My seo observations suggest that the main page may account for up to 30-40% percent of the total search traffic for some sites

    1. Common seo mistakes
      1. Script navigation

Sometimes scripts are used for site navigation. As an seo worker, you should understand that search engines cannot read or execute scripts. Thus, a link specified with the help of a script will not be available to the search engine, the search robot will not follow it and so parts of your site will not be indexed. If you use site navigation scripts then you must provide regular HTML duplicates to make them visible to everyone – your human visitors and the search robots.

      1. Redirects

Redirects make site analysis more difficult for search robots, with resulting adverse effects on seo. Do not use redirects unless there is a clear reason for doing so.

      1. Hidden text, a deceptive seo method

The last two issues are not really mistakes but deliberate attempts to deceive search engines using illicit seo methods. Hidden text (when the text color coincides with the background color, for example) allows site owners to cram a page with their desired keywords without affecting page logic or visual layout. Such text is invisible to human visitors but will be seen by search robots. The use of such deceptive optimization methods may result in banning of the site. It could be excluded from the index (database) of the search engine.

  1. External ranking factors
    1. Why inbound links to sites are taken into account

As you can see from the previous section, many factors influencing the ranking process are under the control of webmasters. If these were the only factors then it would be impossible for search engines to distinguish between a genuine high-quality document and a page created specifically to achieve high search ranking but containing no useful information. For this reason, an analysis of inbound links to the page being evaluated is one of the key factors in page ranking. This is the only factor that is not controlled by the site owner.

It makes sense to assume that interesting sites will have more inbound links. This is because owners of other sites on the Internet will tend to have published links to a site if they think it is a worthwhile resource. The search engine will use this inbound link criterion in its evaluation of document significance.

Therefore, two main factors influence how pages are stored by the search engine and sorted for display in search results:

– Relevance, as described in the previous section on internal ranking factors.

– Number and quality of inbound links, also known as link citation, link popularity or citation index. This will be described in the next section.

    1. Link importance (citation index, link popularity)

You can easily see that simply counting the number of inbound links does not give us enough information to evaluate a site. It is obvious that a link from should mean much more than a link from some homepage like You have to take into account link importance as well as number of links.

Search engines use the notion of citation index to evaluate the number and quality of inbound links to a site. Citation index is a numeric estimate of the popularity of a resource expressed as an absolute value representing page importance. Each search engine uses its own algorithms to estimate a page citation index. As a rule, these values are not published.

As well as the absolute citation index value, a scaled citation index is sometimes used. This relative value indicates the popularity of a page relative to the popularity of other pages on the Internet. You will find a detailed description of citation indexes and the algorithms used for their estimation in the next sections.

    1. Link text (anchor text)

The link text of any inbound site link is vitally important in search result ranking. The anchor (or link) text is the text between the HTML tags «A» and «/A» and is displayed as the text that you click in a browser to go to a new page. If the link text contains appropriate keywords, the search engine regards it as an additional and highly significant recommendation that the site actually contains valuable information relevant to the search query.

    1. Relevance of referring pages

As well as link text, search engines also take into account the overall information content of each referring page.

Example: Suppose we are using seo to promote a car sales resource. In this case a link from a site about car repairs will have much more importance that a similar link from a site about gardening. The first link is published on a resource having a similar topic so it will be more important for search engines.

    1. Google PageRank

The Google company was the first company to patent the system of taking into account inbound links. The algorithm was named PageRank. In this section, we will describe this algorithm and how it can influence search result ranking.

PageRank is estimated separately for each web page and is determined by the PageRank (citation) of other pages referring to it. It is a kind of “virtuous circle.” The main task is to find the criterion that determines page importance. In the case of PageRank, it is the possible frequency of visits to a page.

The PageRank of a specified web page is thus defined as the probability that a user may visit the web page. It follows that, the sum of probabilities for all existing web pages is exactly one because the user is assumed to be visiting at least one Internet page at any given moment.

According to the ranking model described above:

– Each page on the Net (even if there are no inbound links to it) initially has a PageRank greater than zero, although it will be very small. There is a tiny chance that a user may accidentally navigate to it.

– Each page that has outbound links distributes part of its PageRank to the referenced page. The PageRank contributed to these linked-to pages is inversely proportional to the total number of links on the linked-from page – the more links it has, the lower the PageRank allocated to each linked-to page.

– PageRank A “damping factor” is applied to this process so that the total distributed page rank is reduced by 15%. This is equivalent to the probability, described above, that the user will not visit any of the linked-to pages but will navigate to an unrelated website.

Currently, PageRank is not used directly in the Google algorithm. This is to be expected since pure PageRank characterizes only the number and the quality of inbound links to a site, but it completely ignores the text of links and the information content of referring pages. These factors are important in page ranking and they are taken into account in later versions of the algorithm. It is thought that the current Google ranking algorithm ranks pages according to thematic PageRank. In other words, it emphasizes the importance of links from pages with content related by similar topics or themes. The exact details of this algorithm are known only to Google developers.

You can determine the PageRank value for any web page with the help of the Google ToolBar that shows a PageRank value within the range from 0 to 10. It should be noted that the Google ToolBar does not show the exact PageRank probability value, but the PageRank range a particular site is in. Each range (from 0 to 10) is defined according to a logarithmic scale.

This shows that the PageRank ranges displayed on the Google ToolBar are not all equal. It is easy, for example, to increase PageRank from one to two, while it is much more difficult to increase it from six to seven.

In practice, PageRank is mainly used for two purposes:

1. Quick check of the sites popularity. PageRank does not give exact information about referring pages, but it allows you to quickly and easily get a feel for the sites popularity level and to follow trends that may result from your seo work. You can use the following “Rule of thumb” measures for English language sites: PR 4-5 is typical for most sites with average popularity. PR 6 indicates a very popular site while PR 7 is almost unreachable for a regular webmaster. You should congratulate yourself if you manage to achieve it. PR 8, 9, 10 can only be achieved by the sites of large companies such as Microsoft, Google, etc. PageRank is also useful when exchanging links and in similar situations. You can compare the quality of the pages offered in the exchange with pages from your own site to decide if the exchange should be accepted.

2. Evaluation of the competitiveness level for a search query is a vital part of seo work. Although PageRank is not used directly in the ranking algorithms, it allows you to indirectly evaluate relative site competitiveness for a particular query. For example, if the search engine displays sites with PageRank 6-7 in the top search results, a site with PageRank 4 is not likely to get to the top of the results list using the same search query.

It is important to recognize that the PageRank values displayed on the Google ToolBar are recalculated only occasionally (every few months) so the Google ToolBar displays somewhat outdated information. This means that the Google search engine tracks changes in inbound links much faster than these changes are reflected on the Google ToolBar.

    1. Increasing link popularity
      1. Submitting to general purpose directories

On the Internet, many directories contain links to other network resources grouped by topics. The process of adding your site information to them is called submission.

Such directories can be paid or free of charge, they may require a backlink from your site or they may have no such requirement. The number of visitors to these directories is not large so they will not send a significant number to your site. However, search engines count links from these directories and this may enhance your sites search result placement.

Important! Only those directories that publish a direct link to your site are worthwhile from a seo point of view. Script driven directories are almost useless. This point deserves a more detailed explanation. There are two methods for publishing a link. A direct link is published as a standard HTML construction («A href=…», etc.). Alternatively, links can be published with the help of various scripts, redirects and so on. Search engines understand only those links that are specified directly in HTML code. That is why the seo value of a directory that does not publish a direct link to your site is close to zero.

You should not submit your site to FFA (free-for-all) directories. Such directories automatically publish links related to any search topic and are ignored by search engines. The only thing an FFA directory entry will give you is an increase in spam sent to your published e-mail address. Actually, this is the main purpose of FFA directories.

Be wary of promises from various programs and seo services that submit your resource to hundreds of thousands of search engines and directories. There are no more than a hundred or so genuinely useful directories on the Net – this is the number to take seriously and professional seo submission services work with this number of directories. If a seo service promises submissions to enormous numbers of resources, it simply means that the submission database mainly consists of FFA archives and other useless resources.

Give preference to manual or semiautomatic seo submission; do not rely completely on automatic processes. Submitting sites under human control is generally much more efficient than fully automatic submission. The value of submitting a site to paid directories or publishing a backlink should be considered individually for each directory. In most cases, it does not make much sense, but there may be exceptions.

Submitting sites to directories does not often result in a dramatic effect on site traffic, but it slightly increases the visibility of your site for search engines. This useful seo option is available to everyone and does not require a lot of time and expense, so do not overlook it when promoting your project.

      1. Link exchange

The essence of link exchanges is that you use a special page to publish links to other sites and get similar backlinks from them. Search engines do not like link exchanges because, in many cases, they distort search results and do not provide anything useful to Internet users. However, it is still an effective way to increase link popularity if you observe several simple rules.

– Exchange links with sites that are related by topic. Exchanging links with unrelated sites is ineffective and unpopular.

– Before exchanging, make sure that your link will be published on a “good” page. This means that the page must have a reasonable PageRank (3-4 or higher is recommended), it must be available for indexing by search engines, the link must be direct, the total number of links on the page must not exceed 50, and so on.

– Do not create large link directories on your site. The idea of such a directory seems attractive because it gives you an opportunity to exchange links with many sites on various topics. You will have a topic category for each listed site. However, when trying to optimize your site you are looking for link quality rather than quantity and there are some potential pitfalls. No seo aware webmaster will publish a quality link to you if he receives a worthless link from your directory “link farm” in return. Generally, the PageRank of pages from such directories leaves a lot to be desired. In addition, search engines do not like these directories at all. There have even been cases where sites were banned for using such directories.

– Use a separate page on the site for link exchanges. It must have a reasonable PageRank and it must be indexed by search engines, etc. Do not publish more than 50 links on one page (otherwise search engines may fail to take some of the links into account). This will help you to find other seo aware partners for link exchanges.

– Search engines try to track mutual links. That is why you should, if possible, publish backlinks on a domain/site other than the one you are trying to promote. The best variant is when you promote the resource and publish backlinks on the resource

– Exchange links with caution. Webmasters who are not quite honest will often remove your links from their resources after a while. Check your backlinks from time to time.

      1. Press releases, news feeds, thematic resources

This section is about site marketing rather than pure seo. There are many information resources and news feeds that publish press releases and news on various topics. Such sites can supply you with direct visitors and also increase your sites popularity. If you do not find it easy to create a press release or a piece of news, hire copywriters – they will help you find or create something newsworthy.

Look for resources that deal with similar topics to your own site. You may find many Internet projects that not in direct competition with you, but which share the same topic as your site. Try to approach the site owners. It is quite possible that they will be glad to publish information about your project.

One final tip for obtaining inbound links – try to create slight variations in the inbound link text. If all inbound links to your site have exactly the same link text and there are many of them, the search engines may flag it as a spam attempt and penalize your site.

  1. Indexing a site

Before a site appears in search results, a search engine must index it. An indexed site will have been visited and analyzed by a search robot with relevant information saved in the search engine database. If a page is present in the search engine index, it can be displayed in search results otherwise, the search engine cannot know anything about it and it cannot display information from the page..

Most average sized sites (with dozens to hundreds of pages) are usually indexed correctly by search engines. However, you should remember the following points when constructing your site. There are two ways to allow a search engine to learn about a new site:

– Submit the address of the site manually using a form associated with the search engine, if available. In this case, you are the one who informs the search engine about the new site and its address goes into the queue for indexing. Only the main page of the site needs to be added, the search robot will find the rest of pages by following links.

– Let the search robot find the site on its own. If there is at least one inbound link to your resource from other indexed resources, the search robot will soon visit and index your site. In most cases, this method is recommended. Get some inbound links to your site and just wait until the robot visits it. This may actually be quicker than manually adding it to the submission queue. Indexing a site typically takes from a few days to two weeks depending on the search engine. The Google search engine is the quickest of the bunch.

Try to make your site friendly to search robots by following these rules:

– Try to make any page of your site reachable from the main page in not more than three mouse clicks. If the structure of the site does not allow you to do this, create a so-called site map that will allow this rule to be observed.

– Do not make common mistakes. Session identifiers make indexing more difficult. If you use script navigation, make sure you duplicate these links with regular ones because search engines cannot read scripts (see more details about these and other mistakes in section 2.3).

– Remember that search engines index no more than the first 100-200 KB of text on a page. Hence, the following rule – do not use pages with text larger than 100 KB if you want them to be indexed completely.

You can manage the behavior of search robots using the file robots.txt. This file allows you to explicitly permit or forbid them to index particular pages on your site.

The databases of search engines are constantly being updated; records in them may change, disappear and reappear. That is why the number of indexed pages on your site may sometimes vary. One of the most common reasons for a page to disappear from indexes is server unavailability. This means that the search robot could not access it at the time it was attempting to index the site. After the server is restarted, the site should eventually reappear in the index.

You should note that the more inbound links your site has, the more quickly it gets re-indexed. You can track the process of indexing your site by analyzing server log files where all visits of search robots are logged. We will give details of seo software that allows you to track such visits in a later section.

  1. Choosing keywords
    1. Initially choosing keywords

Choosing keywords should be your first step when constructing a site. You should have the keyword list available to incorporate into your site text before you start composing it. To define your site keywords, you should use seo services offered by search engines in the first instance. Sites such as and are good starting places for English language sites. Note that the data they provide may sometimes differ significantly from what keywords are actually the best for your site. You should also note that the Google search engine does not give information about frequency of search queries.

After you have defined your approximate list of initial keywords, you can analyze your competitor’s sites and try to find out what keywords they are using. You may discover some further relevant keywords that are suitable for your own site.

    1. Evaluating the competition rates of search queries

When you have finalized your keywords list, you should identify the core keywords for which you will optimize your pages. A suggested technique for this follows.

Rare queries are discarded at once (for the time being). In the previous section, we described the usefulness of such rare queries but they do not require special optimization. They are likely to occur naturally in your website text.

As a rule, the competition rate is very high for the most popular phrases. This is why you need to get a realistic idea of the competitiveness of your site. To evaluate the competition rate you should estimate a number of parameters for the first 10 sites displayed in search results:

– The average PageRank of the pages in the search results.

– The average number of links to these sites. Check this using a variety of search engines.

Additional parameters:

– The number of pages on the Internet that contain the particular search term, the total number of search results for that search term.

– The number of pages on the Internet that contain exact matches to the keyword phrase. The search for the phrase is bracketed by quotation marks to obtain this number.

These additional parameters allow you to indirectly evaluate how difficult it will be to get your site near the top of the list for this particular phrase. As well as the parameters described, you can also check the number of sites present in your search results in the main directories, such as DMOZ and Yahoo.

The analysis of the parameters mentioned above and their comparison with those of your own site will allow you to predict with reasonable certainty the chances of getting your site to the top of the list for a particular phrase.

Having evaluated the competition rate for all of your keyword phrases, you can now select a number of moderately popular key phrases with an acceptable competition rate, which you can use to promote and optimize your site.

    1. Refining your keyword phrases

As mentioned above, search engine services often give inaccurate keyword information. This means that it is unusual to obtain an optimum set of site keywords at your first attempt. After your site is up and running and you have carried out some initial promotion, you can obtain additional keyword statistics, which will facilitate some fine-tuning. For example, you will be able to obtain the search results rating of your site for particular phrases and you will also have the number of visits to your site for these phrases.

With this information, you can clearly define the good and bad keyword phrases. Often there is no need to wait until your site gets near the top of all search engines for the phrases you are evaluating – one or two search engines are enough.

Example. Suppose your site occupies first place in the Yahoo search engine for a particular phrase. At the same time, this site is not yet listed in MSN, or Google search results for this phrase. However, if you know the percentage of visits to your site from various search engines (for instance, Google – 70%, Yahoo – 20%, MSN search – 10%), you can predict the approximate amount of traffic for this phrase from these other searches engines and decide whether it is suitable.

As well as detecting bad phrases, you may find some new good ones. For example, you may see that a keyword phrase you did not optimize your site for brings useful traffic despite the fact that your site is on the second or third page in search results for this phrase.

Using these methods, you will arrive at a new refined set of keyword phrases. You should now start reconstructing your site: Change the text to include more of the good phrases, create new pages for new phrases, etc.

You can repeat this seo exercise several times and, after a while, you will have an optimum set of key phrases for your site and considerably increased search traffic. Here are some more tips. According to statistics, the main page takes up to 30%-50% of all search traffic. It has the highest visibility in search engines and it has the largest number of inbound links. That is why you should optimize the main page of your site to match the most popular and competitive queries. Each site page should be optimized for one or two main word combinations and, possibly for a number of rare queries. This will increase the chances for the page get to the top of search engine lists for particular phrases.

  1. Miscellaneous information on search engines
    1. Google SandBox

At the beginning of 2004, a new and mysterious term appeared among seo specialists – Google SandBox. This is the name of a new Google spam filter that excludes new sites from search results. The work of the SandBox filter results in new sites being absent from search results for virtually any phrase. This even happens with sites that have high-quality unique content and which are promoted using legitimate techniques.

The SandBox is currently applied only to the English segment of the Internet; sites in other languages are not yet affected by this filter. However, this filter may expand its influence. It is assumed that the aim of the SandBox filter is to exclude spam sites – indeed, no search spammer will be able to wait for months until he gets the necessary results. However, many perfectly valid new sites suffer the consequences. So far, there is no precise information as to what the SandBox filter actually is. Here are some assumptions based on practical seo experience:

– SandBox is a filter that is applied to new sites. A new site is put in the sandbox and is kept there for some time until the search engine starts treating it as a normal site.

– SandBox is a filter applied to new inbound links to new sites. There is a fundamental difference between this and the previous assumption: the filter is not based on the age of the site, but on the age of inbound links to the site. In other words, Google treats the site normally but it refuses to acknowledge any inbound links to it unless they have existed for several months. Since such inbound links are one of the main ranking factors, ignoring inbound links is equivalent to the site being absent from search results. It is difficult to say which of these assumptions is true, it is quite possible that they are both true.

– The site may be kept in the sandbox from 3 months to a year or more. It has also been noticed that sites are released from the sandbox in batches. This means that the time sites are kept in the sandbox is not calculated individually for each site, but for groups of sites. All sites created within a certain time period are put into the same group and they are eventually all released at the same time. Thus, individual sites in a group can spend different times in the sandbox depending where they were in the group capture-release cycle.

Typical indications that your site is in the sandbox include:

– Your site is normally indexed by Google and the search robot regularly visits it.

– Your site has a PageRank; the search engine knows about and correctly displays inbound links to your site.

– A search by site address ( displays correct results, with the correct title, snippet (resource description), etc.

– Your site is found by rare and unique word combinations present in the text of its pages.

– Your site is not displayed in the first thousand results for any other queries, even for those for which it was initially created. Sometimes, there are exceptions and the site appears among 500-600 positions for some queries. This does not change the sandbox situation, of course.

There no practical ways to bypass the Sandbox filter. There have been some suggestions about how it may be done, but they are no more than suggestions and are of little use to a regular webmaster. The best course of action is to continue seo work on the site content and structure and wait patiently until the sandbox is disabled after which you can expect a dramatic increase in ratings, up to 400-500 positions.

    1. Seo tips, assumptions, observations

This section provides information based on an analysis of various seo articles, communication between optimization specialists, practical experience and so on. It is a collection of interesting and useful tips ideas and suppositions. Do not regard this section as written in stone, but rather as a collection of information and suggestions for your consideration.

– Outbound links. Publish links to authoritative resources in your subject field using the necessary keywords. Search engines place a high value on links to other resources based on the same topic.

– Outbound links. Do not publish links to FFA sites and other sites excluded from the indexes of search engines. Doing so may lower the rating of your own site.

– Outbound links. A page should not contain more than 50-100 outbound links. More links will not harm your site rating but links beyond that number will not be recognized by search engines.

– Inbound site-wide links. These are links published on every page of the site. It is believed that search engines do not approve of such links and do not consider them while ranking pages. Another opinion is that this is true only for large sites with thousands of pages.

– The ideal keyword density is a frequent seo discussion topic. The real answer is that there is no ideal keyword density. It is different for each query and search engines calculate it dynamically for each search query. Our advice is to analyze the first few sites in search results for a particular query. This will allow you to evaluate the approximate optimum density for specific queries.

– Site age. Search engines prefer old sites because they are more stable.

– Site updates. Search engines prefer sites that are constantly developing. Developing sites are those in which new information and new pages periodically appear.

– Domain zone. Search engines prefer sites that are located in the zones .edu, .mil, .gov, etc. Only the corresponding organizations can register such domains so these domains are more trustworthy.

– Search engines track the percent of visitors that immediately return to searching after they visit a site via a search result link. A large number of immediate returns means that the content is probably not related to the corresponding topic and the ranking of such a page gets lower.

– Search engines track how often a link is selected in search results. If some link is only occasionally selected, it means that the page is of little interest and the rating of such a page gets lower

– Use synonyms and derived word forms of keywords, search engines will appreciate that (keyword stemming).

; – Search engines consider a very rapid increase in inbound links as artificial promotion and this results in lowering of the rating. This is a controversial topic because this method could be used to lower the rating of one’s competitors.

– Google does not take into account inbound links if they are on the same (or similar) hosts. This is detected using host IP addresses. Pages whose IP addresses are within the range of to are regarded as being on the same host. This opinion is most likely to be rooted in the fact that Google have expressed this idea in their patents. However, Google employees claim that no limitations of IP addresses are imposed on inbound links and there are no reasons not to believe them.

– Search engines check information about the owners of domains. Inbound links originating from a variety of sites all belonging to one owner are regarded as less important than normal links. This information is presented in a patent.

– Search engines prefer sites with longer term domain registrations.

    1. Creating correct content

The content of a site plays an important role in site promotion for many reasons. We will describe some of them in this section. We will also give you some advice on how to populate your site with good content.

– Content uniqueness. Search engines value new information that has not been published before. That is why you should compose own site text and not plagiarize excessively. A site based on materials taken from other sites is much less likely to get to the top in search engines. As a rule, original source material is always higher in search results.

– While creating a site, remember that it is primarily created for human visitors, not search engines. Getting visitors to visit your site is only the first step and it is the easiest one. The truly difficult task is to make them stay on the site and convert them into purchasers. You can only do this by using good content that is interesting to real people.

– Try to update information on the site and add new pages on a regular basis. Search engines value sites that are constantly developing. Also, the more useful text your site contains, the more visitors it attracts. Write articles on the topic of your site, publish visitors’ opinions, create a forum for discussing your project. A forum is only useful if the number of visitors is sufficient for it to be active. Interesting and attractive content guarantees that the site will attract interested visitors.

– A site created for people rather than search engines has a better chance of getting into important directories such as DMOZ and others.

– An interesting site on a particular topic has much better chances to get links, comments, reviews, etc. from other sites on this topic. Such reviews can give you a good flow of visitors while inbound links from such resources will be highly valued by search engines.

– As final tip…there is an old German proverb: “A shoemaker sticks to his last” which means, “Do what you can do best.” If you can write breathtaking and creative textual prose for your website then that is great. However, most of us have no special talent for writing attractive text and we should rely on professionals such as journalists and technical writers. Of course, this is an extra expense, but it is justified in the long term.

    1. Selecting a domain and hosting

Currently, anyone can create a page on the Internet without incurring any expense. Also, there are companies providing free hosting services that will publish your page in return for their entitlement to display advertising on it. Many Internet service providers will also allow you to publish your page on their servers if you are their client. However, all these variations have serious drawbacks that you should seriously consider if you are creating a commercial project.

First, and most importantly, you should obtain your own domain for the following reasons:

– A project that does not have its own domain is regarded as a transient project. Indeed, why should we trust a resource if its owners are not even prepared to invest in the tiny sum required to create some sort of minimum corporate image? It is possible to publish free materials using resources based on free or ISP-based hosting, but any attempt to create a commercial project without your own domain is doomed to failure.

– Your own domain allows you to choose your hosting provider. If necessary, you can move your site to another hosting provider at any time.

Here are some useful tips for choosing a domain name.

– Try to make it easy to remember and make sure there is only one way to pronounce and spell it.

– Domains with the extension .com are the best choice to promote international projects in English. Domains from the zones .net, .org, .biz, etc., are available but less preferable.

– If you want to promote a site with a national flavor, use a domain from the corresponding national zone. Use .de – for German sites, .it – for Italian sites, etc.

– In the case of sites containing two or more languages, you should assign a separate domain to each language. National search engines are more likely to appreciate such an approach than subsections for various languages located on one site.

A domain costs $10-20 a year, depending on the particular registration service and zone.

You should take the following factors into consideration when choosing a hosting provider:

– Access bandwidth.

– Server uptime.

– The cost of traffic per gigabyte and the amount of prepaid traffic.

– The site is best located in the same geographical region as most of your expected visitors.

The cost of hosting services for small projects is around $5-10 per month.

Avoid “free” offers while choosing a domain and a hosting provider. Hosting providers sometimes offer free domains to their clients. Such domains are often registered not to you, but to the hosting company. The hosting provider will be the owner of the domain. This means that you will not be able to change the hosting service of your project, or you could even be forced to buy out your own domain at a premium price. Also, you should not register your domains via your hosting company. This may make moving your site to another hosting company more difficult even though you are the owner of your domain.

    1. Changing the site address

You may need to change the address of your project. Maybe the resource was started on a free hosting service and has developed into a more commercial project that should have its own domain. Or maybe the owner has simply found a better name for the project. In any case, moving to a new address can be problematic and it is a difficult and unpleasant task to move a project to a new address. For starters, you will have to start promoting the new address almost from scratch. However, if the move is inevitable, you may as well make the change as useful as possible.

Our advice is to create your new site at the new location with new and unique content. Place highly visible links to the new resource on the old site to allow visitors to easily navigate to your new site. Do not completely delete the old site and its contents.

This approach will allow you to get visitors from search engines to both the old site and the new one. At the same time, you get an opportunity to cover additional topics and keywords, which may be more difficult within one resource.
