Link Popularity is the number of links to your site from other web sites. The Link Popularity analysis tool searches several search engines ( AllTheWeb, AltaVista, Google/AOL, HotBot/Inktomi, MSN) to determine how many pages are linked to your web page. The more links there are, the easier you are to be found and the more traffic you will get.
Steel White Table’s result:

I have no idea what that means.
