In the coming weeks, your search results and ads on Google will include a +1 button, which users can click to recommend your ads. You don’t need to make any changes to your account in order to take advantage of them. The final landing page URL of your ads can also appear on the Google profile of any user who +1’s your ad.
Think of the +1 button as a way for fans of your business to recommend what you offer, for all their friends and contacts to see. By helping searchers see more personal, relevant ads, we believe you’ll see more qualified traffic. You can also add the +1 button to your site to give your customers the opportunity to +1 your site after visiting it.
We started seeing the button a few weeks ago on the search results and now we can see it on almost all our searches. Unfortunately Adwords didnt mention anything about reporting and if we are going to be able to see how many people click on the button or even which ad/which URL.
