Google’s changes to Adwords
Copyblogger sorts out the deal with Google’s transition from pay-per-click to cost-per-action nicely.
It’s my guess that the new Google landing page algorithm evaluates relevancy in part by not only how much content can be crawled on the landing page domain, but also by how many people end up hitting the “back†button on the browser. It’s not that the subject matter of the affected landing pages is necessarily irrelevant, it’s that about 80% of clickers will not opt-in, and their only option is to go back to the search results and try again.
