In the same way that you regularly try out changes to your AdSense ads
to increase your pay, we're also constantly looking for new habits
to help you earn more. We've been analyzing the performance of the
three obtainable font faces (Arial, Verdana, and Times New Roman), and
have found that each font performs best in unlike ad formats due to
factors like character width. Based on these findings, we'd like to let
you know that we'll be updating a number of of the default font faces
linked with specific ad formats within the after that few existence.
This upcoming change will only affect ad units in Latin-based
font which have 'AdSense default' selected as the font face. If
you've set an account-wide font face, we hope our answer will
encourage you to trial with other font faces on an ad unit foundation.
at present, most ad units set to the AdSense default print face are
displayed in Arial, with a few in Verdana. Here are the new non-payment
font faces we're launching for our ad units:
Arial: 728x90, 336x280, 120x600, 120x240
Verdana: 300x250, 160x600, 468x60, 250x250, 234x60, 125x125, 180x150
Times New Roman: 200x200
While we're optimizing the default font face based on performance
across all AdSense sites, we also recommend experimenting on your own
to decide the best font faces for your ad units and your sites. Just

unit or account-level basis.
