Last Google PR value update time is April 1, and I believe we all know Google's PR update, the basic is at the beginning or the end of the month, the interval is generally 3 months.
And now has July 10, from the last update time, has passed three months 10 days, a total of 100 days!
This 100 days, last month is also June 3 when Google PR value has occurred some changes, but only down, June 3, I have a site, PR from 2 directly to 0
Before some people think is a Google server problem, but if it is a server problem, then why one months, PR value has not recovered?
Before the individual has always thought that Google began to change the PR value of the algorithm!
And now after 100 days, PR value or did not update over, some people will think that Google has given up the PR value, but this possibility is big? Obviously, it's impossible!
And if Google changed the PR value of the algorithm, I believe this PR big update, should give everyone a lot of accidents!
What is the use of specific PR? In some also by the way to introduce you:
Google ranking algorithm: November 16, 2003, Google's search engine using the ranking algorithm named "Google Florida" update, since then, the real use of Google's ranking algorithm has always been its strict conservative one of the core secrets, but usually think there are two new algorithm theory structure , namely "expert system" based on hilltop algorithm and the main page level (Topic-sensitive-pagerank) which is led by Dan Thiesw. According to Atul Gupta's research article, in the hilltop algorithm, the total "ranking" score consists of three parts: Correlation score (page factor), page grade score (non-page factor) and industry score (non-page factor): Correlation score (RS) = 20%, page rank value (PR) = 40% , Industry score (ls) = 40%, where LS refers to the industry score, is the result of the conversion from the expert file link, while the traditional page optimization score only accounted for 20%.
