Adsense allows you to choose fonts
Google Adsense just added new options to choose the fonts for adsense units after they enabled Adsense for Domain feature for all adsense publishers. As of now, you can choose Arial, Times and Verdana. To change the font style for your existing adsense units, go to Manage Ads under Adsense Setup and look for Fonts section. I hope they will add an option to choose custom font name to match with our site’s default font style.
