Backlink

A backlink is a link from some other website (the referrer) to that web resource (the referent).^[1] A web resource may be (for example) a website, web page, or web directory.^[1]

A backlink is a reference comparable to a citation.^[2] The quantity, quality, and relevance of backlinks for a web page are among the factors that search engines like Google evaluate in order to estimate how important the page is.^[3]^[4] PageRank calculates the score for each web page based on how all the web pages are connected among themselves, and is one of the variables that Google Search uses to determine how high a web page should go in search results.^[5] This weighting of backlinks is analogous to citation analysis of books, scholarly papers, and academic journals.^[1]^[4] A Topical PageRank has been researched and implemented as well, which gives more weight to backlinks coming from the page of a same topic as a target page.^[6]

Some other words for backlink are incoming link, inbound link, inlink, inward link, and citation.^[1]
