Google PageRank - practical use

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

   You can determine the PageRank value for any web site with the help of the Google Toolbar, which shows a PageRank value within the range of 0-10. It should be noted that Google ToolBar does not show the exact probability PageRank value, but PageRank range a special place in every range (0-10) is determined based on a logarithmic scale.

   Here is an example: every page has a PageRank real value known only to Google. Derive a displayed range for their ToolBar PageRank, they use a logarithmic scale, as shown in this table
          Real PR ToolBar PR
          January 1 to 10
          10-100 2
          100-1000 3
          1000-10.000 4
Etc.

   This shows that the PageRank displayed in the Google toolbar ranges 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 6-7.

   In practice, PageRank is used mainly for two purposes:

   1. Quick check of sites popularity. PageRank does not provide accurate information about referring pages, but it allows you to quickly and easily get a feel for the level of popularity and sites to follow trends that may result from your SEO work. You can use this "rule" measures for English language sites: PR 4-5 is typical for countries with average popularity. PR 6 indicates a very popular place, 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 reached from the pages of major companies such as Microsoft, Google, etc. PageRank is also useful when exchanging links and in similar situations. You can compare the quality of the sites offered in exchange with pages from your own site to determine whether the rate should be accepted.

   2. Evaluation of 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 assess the relative competitiveness indirect page 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 list using the same query results.

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