Link popularity is the total number of websites that link to your website. Major search engines support “link:” operator. “link:” (without the quotation marks) is typed in front of the URL about which you want to find the number of websites linked. Once you enter this information total count of websites linked to the website you entered appears. This link count is different for different search engines because results shown represent the number of inbound links that are known to that search engine (which will vary based on the size of their database). Major search engines (Google especially) apply many filters against the inbound links thus some inbound links may not be counted in the total.
