Choosing the same font style as the Adsense unit for your website has a good effect on the click through rate of that Adsense unit. I already explained the general process of finding out which font style is being used be a Adsense unit and I would like to use this thread as a reference to write down font information for several Adsense units so that you do not have to find that out by yourself.

I would probably optimize my website for Adsense units will the maximum amount of ads in them. Please note that ad units will use different font sizes if not all ad spots are filled with ads.
