Today I just notice that Adsense is testing a different font type and size for some ad units. I have no idea what kind of impact it can have on CTR, however today I had the highest number of clicks ever.... Anybody noticed that as well? BTW I posted an interesting article on my blog about a glitch on the adsense code. www.ibrowsehere.com Cheers everyone.
Changing fonts in ad block can increase the click through rates , But i didn't noticed any font changes in adsense
I believe the fonts were changed from Arial to Verdana. The font is only noticable on 460x68 and haf banners.
