Hi Dean
The problem is the actual links are maintained within a php database. When Google or another spider visits the page it essentially “sees”
xhttp://www.10bestbingosites.com/index.html/go.php?id=79
This “link” is not assigned as a back link to Captains free casinos. The Captain essentially does not benefit from the link exchange and this “link” will NOT show up as a backlink at Google or any other spider driven search engine.
The problem continues in that most webmasters are aware that non html links do not boost their Page Rank at Google, they go to the site to verify a “link” exchange. They see their link and upon mouseover the browser bar displays “http://www.captains-free-casinos.com”. The script masks the fact that the “true” link is xhttp://www.10bestbingosites.com/index.html/go.php?id=79
So you see they are cheating you and to make matters worse they are making a concious effort to hide that from you by masking the links with this mouse over script.
I hope this makes….
