Last March, Google introduced the +1 button on search results and ads to make it easier for people to get recommendations from the people they trust right when they’re searching. With just a single click, the +1 button lets signed-in Google users publicly recommend content to friends and contacts. Since then, webmasters have been installing the +1 button on their pages. The button has already been installed on over a million websites across the web with over 4 billion impressions daily. These +1 recommendations tell others, “This is something to check out!”

Starting now, advertisers have the option to include the +1 button in any DoubleClick Rich Media ad. This provides advertisers with the ability to include the +1 button in our third-party rich media creatives and to control the inclusion of the +1 button at the creative level. This new option provides rich media advertisers with a simple and scalable way to increase positive and public advocacy of their brand online.

Xbox and AKQA London have worked with DoubleClick to include the +1 button in their upcoming rich media ads for the Gears of War 3 release.

Beginning in October, the +1 button will also appear across display ads served directly through Google Display Network (GDN) and in select mobile inventory. Wherever a +1 action originates, be it from Google’s search engine, in a display or mobile ad on GDN, in a DoubleClick Rich Media ad or from a web page, the +1 endorsement applies universally to a single page. Each +1 action adds to the overall +1 count for a page.

We look forward to helping advertisers accelerate social recommendations of their content by adding the +1 button to DoubleClick Rich Media ad units.
