Nowadays, only a few search engines still tell you who your referrers are. And even those that do, they can't give you the entire list of your referrers. That's where the Potential Referrers wizard comes to help. It allows you to search any of the available search engines, using their most advanced search criteria, to look for additional referrers that may already link to you, or for future partners that you may want to exchange links with.
When you have the results you asked for, you may need to eliminate any unwanted results before we add the good ones into our project. To help us with this task, the application lets us order the referrers by rank (if the SiteRank plugin is installed). If we're not interested in pages that have a very low rank, we can select these websites and remove them.
This feature is only available in the Enterprise version.
