Its not the image traffic either, that shouldnt effect CTR at all.
I have to disagree there since most of my sites are highly image based. My recent CTR is actually up BUT that is due to the fact that my image views in my trade directory are way, way down by about 65% over the past two years. Obviously overall earnings are down massively since total traffic and click volumes are down.
On my B&M specialist sites some were hit by the end of January update by 60-70%, why? They're my exclusive images, nothing has changed yet bang, I'm hit by their so-called 1.2% of queries which turns out to be hundreds of pages a day each for these niche widget sites.
I have to agree that I have seen some very off-target ads recently plus some ads seem to be constantly there to the almost exclusion of all others in a 728 x 90, that sure as heck won't encourage clicking.
