Link popularity refers to the combined quantity and quality of the links pointing to a website. Link quality is determined by the authority level of the website giving the link and its relevance to the site it's pointing to. The link popularity is a significant factor influencing page rank.
Link popularity is an example of the move by search engines towards off-the-page-criteria to determine quality content. Off-the-page-criteria adds the aspect of impartiality to search engine rankings, as citations from other authors in the Web community helps define a site’s reputation. In theory, great sites will naturally attract many links, and content-poor sites will have difficulty attracting any links.
