Google PageRank Feed is Fully Turned Off

Google has reportedly decided to do away with the PageRank scores option in the Google Toolbar. That means, the next time you’re browsing the internet using a tool or your favorite browser that previously allowed you to track PageRank data from Google, you won’t be able to do that anymore. This is because Google has finally cut the link that allowed a browser to fetch data from Google.

Google Fully Turns Off Toolbar PageRank Flow

Google does use PageRank internally and it is still an important factor in their algorithm. But the external PageRank score shown in these tools and the Toolbar was between 0 and 10, whereas the score used by Google internally is way more complex.
Google has been killing off PageRank in the toolbar for years and years. In 2007, Google asked webmasters for feedback on removing PageRank and then in 2009, Google removed showing PageRank like data in Webmaster Tools (Search Console). But in 2013, Matt Cutts told us Google probably will never kill off PageRank in the toolbar. Well, Matt is no longer there and it was done.
Then in 2012, Google stopped updating external PageRank by accident updated PR in December 2013. 

Talking about PageRank score, it had been quite a while since Google updated the PageRank scores. This is because Google had been trying to downgrade the importance of PageRank score which also added up to your Google search ranking.
