Web Visibility: Site/Link Pop Tab: Check the site and link popularity
The site and link popularity tool allows you to examine the relative popularity of different sites.
Alexa ranks web sites depending on the number of times Alexa users visit the site. While this is not exactly accurate it gives a good indication of how your site compares with that of your competitors. Since Alexa is a browser add-on toolbar for a Windows browser (IE), the Alexa statistics will not be accurate for sites that are normally visited by non IE surfers.
Please note that Good Keywords will not install Alexa in your system. It just connects to Alexa's web based information page and retrieves the data about any domain you type in.
The Link Popularity Meter displays the number of web sites that link to your site. This information is extracted from search engines (Altavista, MSN and Google).
