Google's PageRank scoring system seems to be retreating as the company recently confirmed it plans to block access to the general public. 
PageRank, launched in 2000, is an algorithm that checks web pages and ranks them on a scale of one to ten. The ranking is based on several factors, such as the number of inbound or outbound links it has σελίδαs.
The RageRank system helped Google make Internet ranking and search engines very easy, but it also created the SEO shadow economy.
IF you do not know there are companies that claim to enhance a website's RageRank in a variety of ways.
But slowly, as Google began to understand better how the Web works, and new ones appeared technologies that offered more suitable alternatives to the ΡageRank rating system, began to drift away.
RageRank is not already displayed inside Google Chrome, and has disappeared from the Google Search console (formerly Webmasters Tools) since 2009. The Google Open Directory website, which displayed PageRank metrics, was shut down in 2010.
However, according to the company, the RageRank system will not stop altogether. Google said it will continue to be used internally, so no one will know the rankings of the web pages.
