This is problematic, to say the least. We're seeing both a decline in CTR on all ads and fewer clicks on any positioned T1-T3.

I agree: Why the hell would they make both changes at once?! It would have made sense to launch the yellow background OR the click change, not both together.

It's too hard to determine what is causing what.

I've been sitting here rubbing my 'Google = Evil' post-it for the last 20 minutes.

Two issues I'm currently pondering:

1. Is the yellow (which doesn't show up well on some screens, I agree) background not drawing as many clicks as the blue did? In this case one would hope CTR on the side bar ads would increase--but ours has dropped off.

2. The drop off in clicks on T1-T3 ads is due to the fact that we are appreciating fewer mis-clicks due to the click change? AGAIN: Hard to know if it's the colour or the click change. Argh.
