Added a new dimension for publishers in customizing these ad formats

You've long been able to customize the size and colors of your ad units; now, you can also customize the shape by selecting between square, slightly rounded, or very rounded corners.


To get started with these new ad shapes, visit the 'AdSense Setup' tab in your account. As with all format options like sizes and colors, different corner styles will perform better for different publishers. We recommend that you choose the corner style that best matches the look and feel of your sites. Please keep in mind that if your page background color, ad background color, and ad border color are all the same, these new corners won't be visible.
