How to improve CTR?

I'v tried few things like different ad sizes/colors/locations, Adword/Overture. What else can I do?

 

you can beg that your visitors click on the ads in order to use your site

 

work on content to get most relevant ads.

 

Is that against Google's TOS?

 

I think we are not supposed to solicit for clicks..
Some tricks that I saw in some sites is by "blending" Adsense adverts in between contents.

 

Thanks. I will try that and share the results.

 

I know. It was a sarcastic remark.

welcome to the forums obe.

 

Try rotating the color schemes. You can rotate up to 4 color schemes. You can also create custom pallettes to better suit you website.
