6.3 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 Do not publish links to FFA sites and other sites excluded from the indexes of search engines.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 xxx.xxx.xxx.0 to xxx.xxx.xxx.255. 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.
