Adwords Pay Per Action!
If you haven’t heard the news, Google launched its new Adwords Pay Per Action Beta, instead of publishers paying the usual per click cost, they now get to pay per action (filling out a form, registering on a site or making a purchase)
PPA is limited to US residents so far on both the publisher and advertiser sides, PPA FAQ answers some of the questions you might have on mind about this new service, I am not sure how would this effect the affiliate marketing industry and what impact it will have on the established Affiliate Networks out there, I guess that it will mainly depend on the kind of offers PPA will have and what kind of advertisers it will draw.
You can find more information about PPA on the Adwords blog post:
