See this "bigger adsense tricks" http://cutline.tubetorial.com/forums/showthread.php?t=1193 Do you think this is allowed? Any other tips like this you would recommend? I am working on this website http://www.erandolph.com. What do you think so far? Eric
It looks like it requires you to modify the Adsense code, which is against the Program Policies: https://www.google.com/adsense/support/bin/answer.py?hl=en&answer=9997 You are allowed to change the font from within your account: https://www.google.com/adsense/support/bin/answer.py?answer=118574 http://adsense.blogspot.com/2009/02/fontastic-new-options-for-your-ad-units.html
modifying the adsense code is against the google TOS. you should not do that to avoid your account getting ban fro adsense.
