Google's PR value has been updated three times in a row in the past month or so. Compared with the previous situation where the PR value was only updated three or four times a year, Google has gone big this time, which is quite abnormal. The earliest one was June 27, then July 18, and then last week on August 4. The intervals between each update are getting shorter and shorter. Google's frequent updates of PR values have inevitably aroused widespread discussion and speculation in the Internet industry. Although the author here is a recent learner of website SEO optimization, I also boldly put forward some of my own opinions and speculations.
Conjecture 1: Google algorithm adjustment
The first thing that comes to my mind is the reason for Google’s own algorithm adjustment. If the PR value update on June 27 is a normal update, then this update may have caused some errors due to algorithm adjustments or other reasons. Because after this update of the PR value, Google actually changed the PR value of its homepage from 10 to 9. What’s even more shocking is that the PR value of Twitter’s homepage has been reduced to 0.
You know, this coincides with the launch of Google+. In addition, the cooperation between Google and Twitter has expired, and data cannot be captured directly through the API. At this time, Twitter's PR value plummeted to 0, and most users would think that there was something wrong with Google, not Twitter itself. But in fact, the PR value of Twitter's homepage dropped to 0 because Twitter frequently modified their tobots.txt file and Http Header information. Google also didn’t want to take the blame for “burning the bridge when it crosses the river”, so it adjusted the PR value again on July 18 to fix the minor oversights left over from the previous update. This is also explained in Master Zac’s daily SEO post.
But I still have lingering concerns. If the PR value of Twitter's homepage dropped to 0 because Twitter went too far, then how can we explain the PR value of Google's own homepage dropped from 10 to 9? And suppose Google also changed it. Some internal codes of the website cause the PR value to decrease. But is it possible? If Google wants to experiment, it can use other domain names. Why use its own homepage? Therefore, the author speculates that the PR value of Twitter and Google’s own homepage changed during the update this time, most likely because of Google Algorithm changes. Even if this is not the main reason, it is at least a factor.
In fact, one week before Google updated its PR value on June 27, Google’s Panda algorithm was also upgraded. The Panda algorithm is Google's algorithm adjustment for "content farms (i.e. spam content, collected content)" in low-quality content, and has been put into use within Google's English site. Just think about it, although Twitter generates a lot of content every day, is this content not spam?
Although Google’s Panda algorithm has not yet launched a version other than English, it stands to reason that it should have no impact on the country. However, the Panda algorithm was updated again on July 18, and then the PR value was updated on August 4. However, the scope of this update should be relatively small. It is common to adjust the PR value of new sites. Most old sites have few changes. What's more, there is almost no feeling of this PR value update. Most of these new sites are sites that insist on updating original content. For example, this blog took more than 50 days to build the site (during which the server was down for about 10 days). Through normal website SEO optimization work, the PR value was increased to 3. This is inevitably reminiscent of the Panda algorithm. Or maybe in addition to upgrading the Panda algorithm, Google is also fine-tuning the existing algorithm?
Conjecture 2: PR value is fading out of Google algorithm
If the first PR value update is a normal update, and the second PR value update is a reasonable and reasonable way to fix the mistakes in the first update, then why does Google update the PR value for the third time so quickly? Google today gave The PR value of a website is 0, and after a few days it becomes 4. With such frequent changes, wouldn’t it mean that the credibility of the PR value has been lost? Since the minimum credibility has been lost, the PR value will inevitably be lost in Google’s ranking algorithm. Gradually fade out, or even abandon it. The Internet is developing at a rapid pace, and any outdated or imperfect products will be eliminated, not to mention PageRank, a technology invented in 1998.
In other words, maybe Google also wants to tell all webmaster friends that no matter how the PR value changes, it will not directly affect the website’s traffic and keyword rankings. PR value is gradually becoming a cloud. Don’t care too much about PR value. Spend more energy on how to write high-quality content and how to enhance user experience.
In fact, PR value is no longer the ultimate algorithm that kills everything instantly. It has long been just a small standard among many factors to measure the quality of a website. There is no need to cover your head and worry about the PR value.
Conjecture 3: PR value update hype
At the beginning of last year, Google announced its withdrawal from the Chinese market, perhaps out of frustration. In March of the same year, Google began to redirect the domain name of its mainland website "Google China" to "Google Hong Kong" in order to retain a bridgehead in the Chinese market. Since then, it has become more difficult for Google to gain a foothold in China's search engine market, which was already dominated by Baidu. In addition, Tencent's products Soso and the courageous Sogou are impacting the domestic search engine market, and Google's influence in mainland China has also rapidly weakened.
If Google wants to increase the attention of domestic users, it will not be forgotten by the Chinese market. Then frequently update the PR value, causing heated discussions in the industry, which is also a good marketing tool. I think no one can say that Google will never come back, right?
The author personally believes that the above three conjectures about the reasons for Google’s recent frequent updates of PR values are all possible. Perhaps it is only for one of the three purposes, or perhaps Google takes into account all three. It is difficult for the author to make a definite conclusion here. The above three guesses should give everyone some thought.
In addition, the author also saw a speculation on the Internet. The reason is: Google increases the update frequency of PR value in order to display the real-time PR value of the network. First, it can provide the most recent PR value of the website for everyone’s reference to improve user experience. Secondly, everyone pays more attention to the trends of PR value and thus pays attention to Google.
This is not unreasonable. However, after all, PR value is no longer the only criterion for measuring the quality of a website. Webmaster friends must not dwell on this.
