Social-enabled ad campaigns get another tool to market as Google plans to roll out +1 buttons in display ads. So if you like an ad you can +1 it and your friends will be able to see your recommendation on the page.

This +1 button will appear on all Google display ads, both web and mobile, from October. It will also be integrated in search ads and search results. Ads could be in any format including animated GIFs, Flash or mobile ads. A small footnote will be displayed on the bottom of the ad where the +1 recommendation button can be seen along with profile pictures of friends. Google also gives advertisers the choice to opt out of this program and display ads in a normal manner.

Since the time of its launch, the +1 button has been adopted by more than 1 million websites, receiving 4 billion impressions daily. This move by Google is very much on the lines of Facebook's Like button. Since 2007, Facebook has been experimenting with their Like button and have also come up with Sponsored Stories where friends can like ads and that will be shared with everyone on the news feed.  It has also been found out that ads that are recommended by friends have more impact than normal ads.

Research conducted by Nielson on Facebook has shown that 68% of people are more likely to recall an ad recommended by a friend. So considering this research, it can be assumed that Google can definitely expect the +1 button to work, but what can't be guaranteed is the click-through rate for display ads.

What do you think about this concept? Will you click on an ad recommended by your friend? Let us know in your comments below.
