Google trialing cost-per-action
March 21, 2007
Google is trialing cost-per-action adverts on publishers sites in the U.S. I’ve been expecting this for some time as a natural progression for Adwords/Adsense to move to a similar model to affiliates. This will help advertisers avoid click fraud and see more of a return on investment.
More details on the trial are on the Googleblog.
