Today InsideAdsense Announced,
Every once in a while we like to give AdSense features a new look. This time, we’re excited to announce the new and improved referral buttons for AdSense, Firefox with Google Toolbar, AdWords, Google Pack and Picasa. With the sleeker design comes a more web-friendly GIF image and several additional colors to choose from — all to help the button feel more at home on your site.
The new buttons are currently available to US English publishers, and we hope to roll this out for all countries and languages suppoted by AdSense for content. To try out the new buttons, choose Referrals on your AdSense setup tab and follow the instructions to start displaying the button of your choice.
