Google Tweaks AdSense Fonts for Better Performance

By: Chris Crum - August 18, 2009

Google is updating the default font faces associated with specific AdSense ad formats. The decision to do so is based on findings that different fonts perform better with different formats.

"In the same way that you regularly try out changes to your AdSense ads to increase your earnings, we’re also constantly looking for new ways to help you earn more," explains Arlene Lee of Google’s Inside AdSense Team. "We’ve been analyzing the performance of the three available font faces (Arial, Verdana, and Times New Roman), and have found that each font performs best in different ad formats due to factors like character width."


The changes will only apply to ad units that have "AdSense Default" selected as the font face, and are in languages that have Latin-based characters like: 

– Croatian
– Czech
– Danish
– Dutch
– English (US and UK)
– Finnish
– French
– German
– Hungarian
– Indonesian
– Italian
– Norwegian
– Polish
– Portuguese
– Romanian
– Slovak
– Spanish
– Swedish
– Turkish

AdSense ad units are mostly set to Arial as the default, but a few are in  the Verdana font. The new defaults Google is launching include the following:

728×90, 336×280, 120×600, 120×240

Verdana: 300×250, 160×600, 468×60, 250×250, 234×60, 125×125, 180×150

Times New Roman:

While Google is changing the defaults, the company still encourages users to experiment with fonts on their own. There is no reason why other fonts might work better for your own ads.

    I think font change will make a big difference but the problem is if the persons browser does not support the fonts also could this cause problems with page search preformance.

      I think with the defaults it should be ok, because they are pretty standard fonts.

    “There is no reason why other fonts might work better for your own ads.”

    You mean, “there is no reason why other fonts might not work better for your own ads.” right? otherwise you are saying “don’t bother trying to tweak fonts on your own”

    The reason adsense banners work is because they look like they are part of the page; because they look like content. Therefore, they should be in the page design default font. It does not make sense to tweak them depending on the message, because then you are designing something which inherently has no design.
