Google has now restricted the clickable area in AdSense. Instead of allowing a click to be triggered in a broad rectangle around the text, which used to include whitespace in that area, you must now click specifically on the underlined title or the colorized URL below the snippet.
With this change, Google wants to decrease accidental clicks. This has the short-term potential of lowering your AdSense revenues, but I think it’s a good move. Not only because it’s more ethical, but also because in the long run advertisers will be more likely to pay for services that work, and accidental clicks are a kind of system bug. I’m curious how much my AdSense income will drop, I guess all those of us using AdSense will see in a day or two.AdSense, Ads, News Features, Google
