In an effort to test different ad programs/affiliates like adsense/CJ/cb etc, I thought it would be cool to have a script which switched all the ads on my entire site every 50 or so visits. At the end of the day you would be able to see which programs performed the best. Not sure if this exists or not, tried to search for it on DP but couldn't find anything. Was thinking it would go like this (saw this on another thread, no solution was presented): "Make a number of copies of your website. Put a couple of different affiliate programs on them, and have it interchange which page is delivered every 5 or so visitors, or like every visitor. I don't know how this is done, but i know it's been done before. If you want to experiment, and don't just want to lose time, this would probably be the best option for you." 1) So does this exist? If so where can I find it? 2) Is it legal with all the different programs TOS? Thanks
