Ok I have done this test on a 3 of my sites. I put clickbank adds on 3 completely whitehat sites. The day after I do this I lose 25% of my google traffic. I take clickbank off my site and nearly exactly 2 days later my traffic comes back. One of my sites went from 2000 google searches a day to 1300. One thing I have to add is, before I tried clickbank on these sites I only had adsense or amazon advertising. Another thing is that I used the hopad builder or whatever for the adds, which was probably not a great idea. On top of that the 7 days clickbank was on I got no sales anyway. SO I wont be touching clickbank again!!! It could be just that my niche isn't all that great for clickbank. Has anyone else seen this happen? My guess is that google follows the links and see's the spammy sell pages I am linking to with the crappy squeeze pages etc and decides my site is not as good as it used to be? Anyway I would like to hear some opinions about this. I am pretty sick of adsense and amazon adds. I would like to move on but am a bit worried about my traffic.
