Google will be introducing its +1 button and personal recommendations for ad display, following its previous launch of the +1 button on Google search and for publisher sites to make it easier for people to share and discover content across the web. The new feature from Google will enable users to endorse specific ads and make it more likely to appear to their social connections. 

 

The +1 button will begin to appear next month 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 we'll continue to show the ads that will generate the most revenue for you.
