Yet another articleout today calling CPA the Savior of google because Pay per click is bad. I wish people who wrote these articles had some actual experience as an advertiser/publisher.
My biggest concern these days when doing CPA stuff is am I going to get screwed over by the middle man? I can tell you there are a LOT of affiliate networks that are skimming off the top. Now even if you go direct to merchant what is the chance that the merchant isn’t going to screw you over? Lets say they decide to report only 80% of the leads you actually generate? Now in the CPA world this happens all the time, you have to remember these are the exact same people that will do anything for search engine ranking and do any kind of spam as long as they don’t get caught. Advertisers have also created 2 billion dollar adware industry, whose sole job it is to hack your computer and display ads. There are a lot more advertisers out to screw people over then there are people trying to game google adsense.
In short you would be shifting “fraud” from adsense publishers and random people clicking on ads to SEM/Affiliate marketers/SPAMMERS/Adware and Advertisers with very deep pockets who are already doing everything they can to game google.
Google would just turn a mild problem into an absolute nightmare. There would be absolutely no way of detecting CPA fraud. Given that a high percentage of googles revenue is coming from small bands of affiliate marketers I could see this being HUGE.
The CPA Scheme relies on the advertiser telling google when someone bought something. Now if google hosted the transaction/ordering page, and forced people to use Gbuy to buy well then its a totally different ball game as google knows every transaction that happens.
