A person going by the forum name of Critters offers tips to increase AdSense clickthrough rate. They show before and after layouts for what they have done.
The biggest change they did was show related images near their AdSense ads, stating that the ads helped grab the attention of more website visitors. In spite of moving the ads below the fold they increased the advertisement CTR by 300%.
While crazy images may get you more clicks, as stated by Newquestions:
That whole "Paris Hilton" - "look at my clothed dog" type concept. From my experience, people are prepared to click advertisements that are supported by whacky images. The more crazy, the better IMHO.
What about men in drag? Perhaps distasteful, but some women love this
sort of stuff, and perhaps they will click your advertisements to see more.
Critters states that the ads have to be related for it to work longterm:
Putting images next to ads that are NOT relevant to your sites content will only produce short term gains. Smart pricing will kick in and reduce the value of the ads.
Only place images next to ads that you know are matching what the visitor is on your site for (ads for cameras on a camera review site) and that the images match the ads (photos of cameras next to camera ads)
I believe some people have also been using search APIs or scraping some of the engines to grab relevant images, although that might have a few copyright issues associated with it.
As a bonus from that thread, if you hate that damn frog this is the site for you.
