hi, My CTR improved a lot after i changed the ads placement positions. Take a look here. Avinashtech. Also, Please tell me if i am breaking any adsense TOS?
Of course, ad placement is very important for CTR! And you're not breaking TOS because you wrote "advertisment" above your ads, otherwise if you had only post title above ads, that is a mislabelling for adsense policies. So you're fine! That's my opinion but you can ask adsense to check your site if you want, they don't bite!
