Link Popularity
link popularity is determined by the number and quality of websites that have linked to your website (often referred to as "backlinks"). The effects of link popularity are threefold: (1) links to your site give Web users ways to find your site while visiting other sites; (2) links to your site give search engine spiders (robots) trails to follow to find and index or re-index your site; (3) links to your site are essentially votes for your site in search engine ranking algorithms, but not all votes are counted equally.
