PageRank

PageRank is an algorithm used by Google to rank websites in its search engine results pages (SERPs). PageRank was developed by Google co-founder Larry Page and is named after him. PageRank is a way of measuring the importance of website pages.

The algorithm assigns a numerical weighting to each element of a hyperlinked set of documents, such as the World Wide Web, with the purpose of "measuring" its relative importance within the set. The algorithm may be applied to any collection of entities with reciprocal quotations and references. The numerical weight that it assigns to any given element E is referred to as the PageRank of E and denoted by P(E). The basic idea is that more important websites are likely to receive more links from other websites.
