Informations

PageRank™ is one of the components constituting the ranking algorithm of web pages by Google™. Each page detected and indexed by Google™ is assigned a "PR" (for PageRank™) between 0 and 10. The importance of this indicator seems to decrease over time in the positioning of pages in SERP but it remains a good indicator of the popularity of pages.
