Sergey and Larry took this concept and applied it to the web by tracking references (links) between web pages. That is, by looking at the number of other scientific papers referencing them. The idea was inspired by the way scientists gauge the “importance” of scientific papers. PageRank aimed to solve this problem by making use of the “citation (link) graph of the web,” which the duo described as “an important resource that has largely gone unused in existing web search engines.” “Junk results” often wash out any results that a user is interested in. ” “Anyone who has used a search engine recently can readily testify that the completeness of the index is not the only factor in the quality of search results. Here’s what Sergey and Larry said about the state of search engines in their original paper: The relevance of their search results left a lot to be desired. Early search engines like Yahoo and Altavista didn’t work very well at all. That brings us to an important point: Search engines weren’t always as efficient as Google is today.

“Our main goal is to improve the quality of web search engines.” They described their motivation as follows: Google co-founders Sergey Brin and Larry Page devised PageRank in 1997 as part of a research project at Stanford University.

PageRank (PR) is a mathematical formula that judges the “value of a page” by looking at the quantity and quality of other pages that link to it. Its purpose is to determine the relative importance of a given webpage in a network (i.e., the World Wide Web). To discuss other similar metrics that exist today, which may make suitable replacements to the deprecated public PageRank “score.”īeginner’s guide to link building What is Google PageRank?.To explain the basics of the PageRank formula.To set the record straight about the importance and relevance of PageRank in 2018.With that in mind, the aim of this post is threefold: In his talk, he reminded the audience that PageRank is still a part of their algorithm it’s just that the public score (i.e., Toolbar PageRank) no longer exists. Just a month ago, Gary Illyes spoke at a conference I attended in Singapore ( here’s me with him!). So that tweet is straight from the horse’s mouth, so to speak.)īut this year-old tweet isn’t my only evidence. But here’s the thing: PageRank still plays a vital role in Google’s ranking algorithm.ĭYK that after 18 years we’re still using PageRank (and 100s of other signals) in ranking? Here’s a comment I found on another article about PageRank that sums up this way of thinking: For this reason, some SEOs view PageRank as an outdated and irrelevant metric that has no place in modern-day SEO. It showed the Google PageRank of every page you visited on a logarithmic scale from 0–10.īut even before Google officially removed support for Toolbar Pagerank in 2016, they had already ceased to update it for many years.
