About Google PR You may not know some of the things

PR has been a lot of webmaster as the only measure of the weight of the site, we exchange links in the evaluation of the value of the competitor site, the Prime Minister does not open it, which instead let a lot of webmaster only too much focus on the PR value also ignores the other aspects of the optimization factors. Then Google PR What things may be you do not know it?

1. PR can only evaluate the number of pages outside the chain and the quality of the Web page outside the chain, and can not refer to the page weight. In other words, PR is only related to the quantity and quality of the chain, regardless of other factors.

2. A PR4. A Web page with only 5 outbound links is worth more than a PR8, but a Web page with 100 outbound links is much more valuable.

3. From PR0 to PR1 is relatively easy, from PR1 to PR3 will be difficult, from PR3 to PR4 will be more difficult, PR5 is even more. A PR5 site to reach PR6 may have to pay 4 times times more effort than before.

　　

3. To evaluate the value of an outside chain, simply use his PR to divide the number of links exported on its Web page.

4. If the weight of the pages you link to is reduced, your PR will also be reduced.

5. All pages on a website have PR, and the PR of the subdirectory is not necessarily lower than the PR of the root directory. Because the spider is the Web page as the unit to crawl, rather than the whole station as a unit.

6. Google PR every moment in the calculation, but webmaster Tools on the display of the PR is only every 3 months after the update of Google's snapshot time point of the PR value.

7. Often update the content of the site does not necessarily promote PR, often updated outside the chain will promote PR.

8. Google in the calculation of the PR value does not take into account content, content only when users produce search matching needs only relevant.

9. High PR does not guarantee high ranking, PR is just a point in many ranking factors.

10. The external chain on the micro-encyclopedia will not promote PR, the outer chain of Wikipedia with "No-fllow", is invalid link.

11. There are too many links to the same page on the same page, and these links are only recorded by Google as a vote. Just like a person cannot repeat the vote on the same person.

12. A page can only contribute to one voting value.

13. If the Web page links to a blocked page, your site may also be blocked.

14. Web pages for their own links can not enhance the PR, just as their own vote is invalid.

DMOZ and Yahoo directory can not make PR value steep rise.

PR is only Google patent, and the role is increasingly being diluted, and Baidu has nothing to do.
