PageRank - SEO Glossary

Developed by one of the co-founders of Google, Larry Page and registered trademark by him, PageRank is an algorithm that makes it possible to evaluate the popularity of a web page in order to index it properly before its presentation to Internet users.

PageRank is much less important today than in its early days, but it is still a key element for SEO. PageRank is often associated with link juice or the ToolBar PageRank, which no longer exists.
