Google changed the AdSense ads by making less of the AdSense ad area clickable to prevent accidental clicks. Fair enough. In theory if the CTR drops because their are less accidental clicks, then the amount paid per click should go up because the clicks that do happen are more purposeful. Or something like that.
Anyway, some people seem to have seen their CTR drop through the floor. Others haven’t been affected that badly by the change to the AdSense ads. It hasn’t seemed to change my CTR one way or the other on any of my blogs.
After noticing something earlier today, I went on a hunt for people running sidebar ads and was actually surprised by how many blogs that I know used to run AdSense that don’t anymore. But, eventually, I found a post on mommy bytes that had the ads in the right sidebar. The clickable area was indeed the new smaller area. Here is a poor image to show it, but feel free to click over to Angela’s site to check for yourself.

Then I went did a Google search for “cats” and came up with this:

Cool. Fewer accidental clicks all around.
But wait. I said I noticed something that made me start this investigation in the first place. I was in my Gmail account reading a newsletter email from Yaro Starak and had my house hovering over one of the ads that Gmail shows and noticed it has a different clickable area:

So wait a second. Google still gets to use the big clickable email on ads that they display on Gmail. And then they put those ads right next to the scrollbar where people have to click to read the rest of their emails. That can’t possibly be a recipe for accidental clicks.
But I’m sure Google has something in place to determine which of those clicks were accidental and return that money to the advertisers.
