Link popularity is a general representation of the total number of sites and their quality which link to a particular site (or individual web page). Almost all the major search engines including Google, Yahoo & MSN support the “link:” operator. Type in link: in front of the URL about which you want to know.

Link popularity is important because it plays a major role in the visibility of the website and is used by search engines in determining the ranking on a site in search results. Generally the more inbound links, the higher will be the position of the site.
