Adsense ads coming with +1 button

AdSense display ads will now feature the +1 button. From the next month, Google will introduce the +1 button and personal recommendations to display ads. The +1 button will begin to appear on AdSense for Content and AdSense for Mobile Content display ad formats -- image, animated gif, and Flash. +1s will be one additional signal to help determine an ad's relevance and google will continue to show the ads that will generate the most revenue for the publishers.

                 Google has previously launched the +1 button on Google search and for publisher sites to make it easier for people to share and discover content across the web. Soon, publisher's users will be able to endorse specific ads and make the ads more likely to appear to their social connections. Google believe that these recommendations could help publisher's readers notice ads on their site more, leading to higher returns for you over time. If the publishers prefer not to show the +1 buttons on display ads on their pages, they can opt out in their account.
