Word of the week: PageRank

By Word of the Week on August 5th, 2013

PageRank is an algorithm that Google uses to estimate the relative importance of pages around the web. The concept behind the algorithm is that a link from page A to page B can be seen as a vote of trust from page A to page B. Therefore, if there is a higher number of links to a page, there is a higher probability that the page is important—thus causing the page to rank higher among similar pages. Essentially, links are considered votes and some votes are weighted more heavily than others. These scores are compared against votes of other pages to determine the order of importance. Another factor that contributes to the ranking is an analysis of the page that casts the vote, as votes cast by more important pages weigh more heavily and make other pages more important. Google uses PageRank in tandem with text-matching techniques to make sure highly ranked pages are both relevant and important. Overall, PageRank is an important factor in ranking well on Google, so organizations must strive to receive high rankings to optimize SEO efforts. (Side note: in the SEO world, the acronym “PR” stands for PageRank, not to be confused with public relations!)
