Link popularity checker 
Link popularity is the number of other Web sites that contain links to your site. Many factors can effect the search results returned by search engines. A major factor in search engine ranking is "linkage", that is, other web sites with links pointing to your site. A web site with a larger amount of "other sites" linking to it would score a higher relevance ranking than one with fewer links.
