A few weeks ago, Google made a change to the AdSense units so that the entire box is no longer clickable. Now, only the actual URL and title can be clicked on instead of the entire region. Google has announced in their official AdSense blog that the purpose of this is to prevent accidental clicks for the advertisers. However, I can tell you that my effective CPM dropped by nearly 50% as a result. (CTR didn't drop nearly as much) Has anyone else experienced such a drastic change as a result of this?
