Adsense: A Click is No Longer a Click.
This morning it was reported that Google is changing what constitutes a click on an AdSense ad. In the past, a click on the URL, title or background of the ad would trigger a click and earn an AdSense publisher money. In the future, a click on the background of the ad will no longer trigger a click event and an AdSense publisher will not make money.
In short, a click occurs only if a user clicks on the title or URL of the AdSense ad.
The reason Google is implementing this change for their contextual ads are to "reduce accidental clicks and increase value for advertisers."From Internet Advertising & Marketing and
