I turned on the computer in the morning and checked the relevant information of my website as usual, and suddenly found that the PR of the Genital Warts Medical Network website had changed. After being surprised, I checked the PR of my friend's website and found that the PR of their website had also increased or decreased to varying degrees.
Case:
www.chhpv.com Original PR2 Now PR4
A simple algorithm based on the previous rules of Google Page Rank:
For example, a small group consisting of 4 pages: A, B, C and D. If all pages link to A, then the PR (PageRank) value of A will be the sum of B, C and D.
PR(A) = PR(B) + PR(C) + PR(D)
Continue to assume that B also links to C, and D also links to 3 pages including A. You cannot vote twice on one page. So B gives each page half a vote. Using the same logic, only one-third of the votes cast by D count towards A's PageRank.
PR is updated once every three months. According to normal calculations, the next Google PR update should be around September 25. But since the PR update on June 22, two more small PR updates have been carried out.
Today’s update is so large and wide in scope, should it be classified as a major update? Or a minor update?
Google's anomaly makes us think about several questions:
1. What exactly is Google doing?
2. Will PR be updated under normal rules around June 22?
3. Does Google pay less attention to backlinks than before?
4. Will Google’s update still use the previous three-month standard?
5. Is Google studying how to better combat PR cheating?
From the recent PR updates, we seem to be able to discover an important message revealed by Google’s adjustments: website quality will ultimately determine PR. I don’t know if everyone agrees with my point of view. If there are any mistakes, I hope you can criticize and correct me.
To sum up
1. Make friendly links and cross-links with websites with high web quality, high PR value, and similar websites.
2. Post articles with valuable links, which can be reproduced by more sites and bring valuable incoming links.
3. Web page quality (DIV+CSS) page optimization should be done as well as possible, including code optimization, keyword optimization, etc.
4. Use text links and try to avoid using image links (image search engines do not recognize them)
5. Do not have more than 20 friendly links on the homepage. More is not always better.
6. Website content should be updated quickly to allow search engines to visit your webpage frequently.
7. Do not exchange links with websites that have been hacked.
8. The page is beautiful and the user experience is better
These not only affect the PR of the website, but are also useful for Baidu, GOOGLE, and other search engines. Webmasters are studying search engines, and search engines are constantly changing. They are constantly paying attention to how the value of PR will develop in the future. Everyone is welcome to discuss actively.
