Summary: The PR value, the webmaster are estimated to be very sensitive, but only a number can determine a website good or bad? The answer must be no.

2 Prerequisites for the PR algorithm:

1, the Web page has been cited several times, the GG search that it may be a very important link; a Web page, although not referenced many times, is also considered potentially important when it is referenced by important Web pages; The importance of a Web page is passed on the average to the pages it references, an important page called authority ( authoritive) Web page.

2, assume that users start a random access to a Web page collection of a page, and then follow the link to the page to browse the Web page, not back to browse, then the probability of browsing the next page is the PR value of the Web page is browsed.

Factors influencing PR:

The PR value is embodied in 11 values from 0 to 10, with a horizontal green histogram shown on Google's toolbar and 0-level case white. It is for the Web page, not the site, so a site's home page and internal pages often have very different PR value. Due to the Google market expansion process, the PR value of Chinese web pages as a whole is lower than the English page. For the Chinese site, with 3-level PR is the basis, 4-level PR to achieve the standard, 5-level PR is good, and 6, 7-level PR even quite excellent site. Of course, because the most direct impact of PR is from the link, so this rating does not represent the level of content, site content quality of the impact of the PR is indirect, long-term. According to the PR value of the algorithm principle, we know that the impact of a website (home) PR value of the main factors include:

1, the quality of the site's import link:

According to the previous analysis of the high quality import link, the high PR value needs to obtain the link from the following websites:

Join the search engine classification directory and have joined the directory of the site exchange links

Get links from PR values of no less than 4 and related or complementary sites to your topic

Your links are now large, high profile, frequently updated important sites (such as news sources)

Sites with which you exchange links have little export links

With high content Quality website link (pr value rise potential big)

2, export the number of links:

According to the principle of PR calculation, because "the importance of a Web page is passed to the page it refers to," so in turn, too many export links within a page will potentially cause the loss of the page PR value. However, from the content point of view, the appropriate number of linked to the topic of the export links to the search engine to bring a good impression. Therefore, a page, especially the number of export links to the master, should take into account the PR value and keyword content between the two balance, that is, control the number of export links, to no more than 10.

3, search engine contains a site number of pages

In the discussion of SEO, people pay too much attention to the core keyword rankings and the performance of the home page, but often overlooked a very important question: that is, search engine on a site included in the number of pages. The latter also has extremely important significance in the SEO. A key keyword Query rankings poor site, may be crawled by a large number of pages and users use other keyword queries, the inside page to get the top three rankings. Because the user searches uses the keyword to have the dispersibility, causes this kind of situation often to bring the huge visit quantity to the website.

Because the number of pages directly affect the amount of access, so the impact on the PR value is also very large. The more pages are included, the higher the homepage pr. However, it needs to be emphasized that the amount referred to here refers to the ratio of the number of pages included and the total number of sites, rather than the absolute number of pages included. For example, a site with 50 pages is included in 10 pages, the site is included in the ratio is 1/5, a 5,000-page site has been included in 500 pages, the ratio is 1/10, the result is a collection of 10 pages than 500 pages of the site also has a more ranked advantage. But for each search engine, how far to achieve the ratio is good, there is no relevant data.
