According to official news from Google, Google has permanently ceased the update of the PageRank value (PR value). Meanwhile, Google hopes that webmasters do not overly focus on PR values and should not concentrate solely on PR values while neglecting the true content of their websites. In early April this year, Google conducted its last PR value update and did not update it for over five months after that. Traditionally, Google's PR value update cycle was around three months. The cessation of Google PR value updates has dealt a significant blow to the link-buying industry and has left many individuals involved in Google SEO promotion without a reference standard. For a long time, Google's PR value has been one of the most important indicators for measuring the importance and even the value of a website, as well as being the optimization goal for many SEO personnel. Now that the Google PR value has been abolished, perhaps the only measures of a website's importance left are the number of indexed pages, the number of external links, and the website traffic. The halt in updating Google's PR value is likely related to the strong development of social networks represented by Facebook. Google's search results have already become more personalized and real-time, with social factors taken into account. Facebook's "like" evaluation system may be what Google is now favoring. It can be said that the death of PR values signifies the full arrival of the social networking era. The previous method of searching through indexed URLs will comprehensively shift towards a socialized search approach. Whether Google can adapt and withstand Facebook's aggressive advances remains unknown. The most core indicator of a website's importance will always be its content. SEO will no longer be the key means for websites to attract traffic; how to maintain the relationship between the website and users, encourage better user participation, and continuously attract and retain users are issues that website promotion personnel need to focus on. Because in the era of socialized search, each user becomes a direct evaluator of the website's value - perhaps the charm of socialized search lies precisely in this aspect.
