3.6 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 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.
Here is an example: each page has a real PageRank value known only to Google. To derive a displayed PageRank range for their ToolBar, they use a logarithmic scale as shown in this table
Real PR ToolBar PR
1-10 1
10-100 2
100-1000 3
1000-10.000 4
Etc.
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.

3.7 Increasing link popularity
3.7.1 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 pro
