PageRank is the first Google algorithm developed to evaluate the quality and importance of web pages. It assigned a specific number value from 0 to 10 to the indexed pages, where 0 indicates the lowest and 10 – the highest quality.

What is PageRank? The name of the algorithm is a trademark of Google. PageRank was patented in 1998 by Stanford University, and the license rights were passed to Google for 1.8 million shares, which in 2005 was worth $336 million.
