Don't goog collect either way? You get presented an ad: - click and advertiser gets charged - don't click and the ad word cost goes up so advertiser pays more to present the ad next time (because click through rate went down) I always thought it was an amazing scheme, collect both ways. Or did I get it wrong? Was ages ago when I looked at it. I don't click either...
