How to put adsense code into my signature of PHPBB forum on my site?

Please help me?

Hi,

I have PHPBB forum on which I run adsense? But CTR is very low. So I am planning to put one adsense block(125X125 button) in my signature. I think this will improve the CTR. But I don't know how to add adsense code to my signature? Please help me out.

If you do that, you have to make sure you only have 3 or less posts on one page. This is because of the 3 adsense ads to a page rule. I wouldn't recommend this option.

Either you dont post in your own forum or you dont do this..this can get you out of adsense i doubt..as you must have placed banner on top and bottom and counting with those signatures will cross 3 and ...
