Google adsense blog announced the launch of new feature in Google adsense and that is adjust your font size.
The default adsense font is set to small and you can change it to medium or large.
Keeping it medium or large will make your adsense advertisement more prominent.
Though Adsense blog also mentioned that they feel that the default adsense font is too small and soon they will be chnaging into medium by default.
we’ll also be changing the default font size across AdSense in ad units from ’small’ to ‘medium’. We’ve heard from some of you that the current font size can be too small, and our testing also showed that slightly larger font sizes improved performance
Seems like Adsense is giving all possible chances to adsense pulisher for increasing their adsense revenue.
