Google just introduced a brand new slap to get rid of fake affiliate review sites and blogs. See what Perry Marshall says about it Code: http://www.perrymarshall.com/product-review-google-slap/ . Quick Fix? Read number 1 comment at Code: http://cashtactics.net/07/21/urgent-update-did-google-just-bomb-review-landing-sites/ . I believe it gives you detailed instructions on how to avoid it. Solution? As Perry Marshall suggests, aim for listbuilding. Build trust, and market your affiliate stuff to the list. This is what you should be doing anyway, without the slap or not. This increases the value you get for each ad click by at least %300 more. You proabably know this already, but, it's never enough to say it. Someone you promote an affiliate product to through email is much more likely to buy from you than if you were just simply and only sending them to a review page and never establishing contact with them again.
