Hey Well google has made one slight change to my ad formats and it has resulted in a big increase in CTR - I reckon the CTR has doubled at the moment. I am not sure if this is old news or not but the adsense ads on my sites now have both the heading and the url of the website underlined It makes the unit as a whole look more clickable and it is certainly performing much better. I am using these colours: Border: #FFFFFF Title: #133ECE Background: #FFFFFF Text #333333 URL: #133ECE Anyone else noticed this on their ads?
This is very common technique on ads optimization, you can actually find this suggestion at Adsense help center It really work on improving ctr
