I was searching for some clickbank products and I stumbled on one affiliate. His promotion is very tricky. He uses his own domain in the display URL and then when user clicks on it, he is taken to the product landing page. The URL on the address bar says it is a product's page, not affiliate's display url. So, this is definitely not iframe. Also, when you click the first time on his ad, you are taken to his affiliate link. But if you click second time on his ad, you are taken to his fake landing page, which has no offers but only dummy text with dynamically generated keywords that user was searching on google. We know that display url and destination domain must be the same. However this guy is somehow able to get away with that. He even got all of his ads approved. This seems to trick google into believing that display and destination domains are same (because second time you click on ad, you are actually taken to a fake landing page with searched keywords, so the second time, display and destination domains do match, and that is why he gets a high quality score), but in fact display and destination do not match the first time user clicks on ad, but only on the second time. Do you have any idea how this is done? What's going on here?
