When it comes to exchanging friendly links when doing website SEO optimization, so far most webmasters first consider the PR value of the other party's website. The author has always believed that this is not entirely correct. The PR value has indeed once become the only criterion for measuring whether a website's SEO optimization is good or not. However, the PR value in the current Google ranking algorithm is no longer the ultimate algorithm that kills everything instantly, especially today when the PR value is frequently updated. It seems now, or perhaps earlier, that the exchange guidelines for friendly links should abandon the concept of "PR first", observe the target website in an all-round way, and measure whether a website is worth exchanging from multiple angles and multiple standards. Friendly links.
PR value updated three times in a row within 40 days
Anyone who is an SEOer or webmaster friend should know that Google has updated the PR value three times in a row in the past month or so. The most recent one was on August 4th, and the other two were on June 27th and July 18th. There were many wrong adjustments in the PR update on June 27, including Google actually lowering the PR value of its homepage from 10 to 9. Then Google updated the PR on July 18, correcting most of the previous mistakes. Now that the PR value is updated again on August 4th, the PR value of many new sites has been greatly improved, including this blog's jump from the original 0 to 3.
The author believes that this PR value update cannot be said to be a completely wrong adjustment (because the author fully believes that some webmasters, including the author, have indeed improved the website’s PR value through conscientious SEO optimization), but at least there are still some mistakes. of. According to the author's observation, several new sites actually do not do well in website SEO optimization. For example, they do not have much substantive content, nor do they have a good external link foundation, etc. But their PR values have all increased to 2 or 3, or even 4, which is abnormal. Moreover, the PR value of some internal pages of many websites has also been improved, including many newly established article pages. In addition, the PR values of most old sites have not changed.
Google’s PR value is updated so frequently, which is really not like Google’s style. Anyone who is engaged in the Internet knows a little bit that the PR value update frequency was only 3 to 4 times a year. The author believes that if the PR value is updated frequently during this period, it is due to the fluctuation of Google servers. Well, we will soon usher in the fourth adjustment of PR value this year. And if it is not the reason for Google server adjustment, then we have to consider the importance of PR value. If a website’s PR value changes frequently without much change, how can we trust the authority of Google’s PR value?
PR value is not the only measure of a website
The effectiveness of website SEO optimization cannot be based solely on the Google PR value. This is a view that the author has always supported. First, the Internet is changing rapidly, and the importance of PR value has been slowly diluted from the ultimate algorithm of that year. Udi Manber, Google's vice president of engineering, said in Google's official blog, "The most famous part of our ranking algorithm is PageRank (Google PR value), which was developed by the two founders of Google - Larry Page and Sergey Brin. Currently PageRank is still used, but it has become part of a larger system. "That is to say, the PR value has been "reduced" from the main part of Google's algorithm at that time to just a part of today's Google algorithm. It can be seen that PR value is no longer the only criterion for measuring the appropriateness of website SEO optimization.
Second, the PR value is developed and used by Google. How can Baidu, the domestic search engine overlord, dare to follow in Google's footsteps? If Baidu wants to dominate the search engine world, it must "surpass" Google and have its own set of Unique technical algorithms and systems. In other words, when doing SEO optimization for Baidu, Baidu does not take the PR value too seriously. The PR value is just an algorithm used by Google to measure websites. You have to follow Baidu. When optimizing websites for SEO, the different inclusions and rankings of Baidu and Google can illustrate the different focuses of the algorithms of the two search engine emperors.
Therefore, when it comes to measuring whether a website’s SEO optimization is good or bad, how can you make a conclusion based solely on the PR value?
