I've heard of webmasters replacing their adsense blocks and rotating similar text affiliate programs instead. Has anyone had experience doing this? I've been looking at programs like http://www.advert-rotator.com/ and http://www.informativeresources.com/adrotator.htm Adsrotator. If you could track what affiliate programs your visitors are clicking on, you would have a better idea of what to serve to your visitors to get sales. Again, if you have experience with this please share!!
