PageRank 140
Deprecation
PageRank was once available for the verified site maintainers through the Google Webmaster Tools interface.
However on October 15, 2009, a Google employee confirmed[44] that the company had removed PageRank from its
Webmaster Tools section, explaining that "We’ve been telling people for a long time that they shouldn’t focus on
PageRank so much; many site owners seem to think it's the most important metric for them to track, which is simply
not true."[44] The PageRank indicator is not available in Google's own Chrome browser.
The visible page rank is updated very infrequently.
On 6 October 2011, many users mistakenly thought Google PageRank was gone. As it turns out, it was simply an
update to the URL used to query the PageRank from Google.[45]
Google now also relies on other strategies as well as PageRank, such as Google Panda[46].Notes
