You may have noticed that some of your ad units have started to look a little different lately -- we’re happy to announce that, just in time for spring, we've given our standard ad units a fresh makeover. After extensive testing and research, we’ve found that the new formats are not only visually appealing to users, but they also perform even better for publishers and advertisers. We're in the process of rolling out this change to all ad units, and you should see that your ad units are automatically updated over the next few days. But, before you rush to make sure all of your ad units still match your site, please be assured that the fonts and colors of your ads won't be changed.

Although it’s not possible to opt out of the new designs, we hope that you and your site visitors will find our new ad formats clearer and more attractive. We're always testing new ways to improve the look and feel of our advertisements, so stay tuned for more format options in the future.
