Website optimization you still tangled up PR value?

SEO to do the site when it comes to the exchange of links, so far most of the webmaster first consider the PR value of the site. The author has always thought that this is not entirely correct, PR value did once become a measure of website SEO optimization do good and bad only standard. However, the PR value in the current Google ranking algorithm is not the second kill all the ultimate algorithm, especially in the PR value of today frequently updated. Now it seems, or earlier, the exchange of links to the rules should abandon the "PR-oriented" concept, a full range of observation of the target site, from a number of angles, a number of standards to measure whether a site is worth exchanging links.

PR value is updated continuously 3 times in 40 days

As long as seoer or webmaster friends should know the last one months more time, Google has continuously updated the PR value of 3 times. The last one was August 4, and the other two were June 27 and July 18 respectively. The PR update of June 27 was a lot of wrong adjustments, including Google's own home page PR value from 10 to 9. Then July 18 Google Update PR, will be most of the error correction. Today, August 4 again updated PR value, making many new stations PR value of a wide range of promotion, including this blog from the original 0 jump to 3.

　　

The author believes that the PR value update can not be said to be completely wrong adjustment (because I fully believe that including the author part of the webmaster is really through the diligent SEO optimization to improve the PR value of the site), but at least there are some mistakes. According to the author observation, there are several new stations in fact, SEO optimization on the site does not ideal, such as not much substance, there is no good outside the chain basis and so on. But their PR value has been raised to 2 or 3, or even 4, which is not normal. And there are a lot of sites in the part of the PR value has also been promoted, many of which have just been established soon article page. In addition, most of the old station PR value has no change.

Google PR value updated so frequently, really not like Google's style. People who are engaged in the internet have a bit of knowledge, before PR is worth updating frequency only 1 years 3 to 4 times. The author thinks, if this period of time PR value is frequently updated, because of the fluctuation of the Google server. Well, we will soon usher in the PR value of this year for the 4th time adjustment. And if it is not the reason Google Server adjustment, then we have to consider the importance of PR value. If a site in the absence of too big changes in the case, the PR value is often changed, how do we believe that Google PR value authority?

　PR value is not the only measure of website

SEO optimization results can not only one-sided reference to Google PR value, this is the author has always supported the point of view. First, the Internet is fast changing, the importance of the PR value has been gradually diluted from the ultimate algorithm of that year. Google Engineering Vice President Udi Manber in Google's official blog said "in our ranking algorithm, the most famous part is PageRank (Google PR value), it is by Google's two founder--larrypage and Sergey Brin development." PageRank is still being used, but it has become a part of a larger system. "That is, the PR value from the main part of the Google algorithm at that time, has been" reduced "as part of the Google algorithm today. Visible PR value is no longer a measure of website SEO optimization is the only standard of appropriateness.

Second, the PR value is developed and used by Google, and the domestic search engine overlord Baidu How dare to walk Google's footsteps? Baidu wants to unified search engine's Jiangshan, must "surpass" the Gu ge, has own unique technology algorithm and the system. In other words, Baidu to do SEO optimization, Baidu will not put the PR value is too heavy, the PR value is only Google to measure the algorithm of the site, you have to follow Baidu. SEO optimization in the site, Baidu and Google's different collection, different rankings can explain the two search engine Emperor's algorithm focus is different.

Therefore, the measurement of a website SEO optimization is done good or bad, how can you only rely on the PR value of a point to jump to the conclusion?
