Google is exploring a  new mobile ad function that operates similarly to that of a Facebook ad; you can swipe and gain information of the advertiser or company.

This could help provide a cheap solution for your online advertising efforts. Even sweeter, you only get charged when someone interacts with your ad.

These Google ads also allow for “ad extensions” cards that let users see additional information, such as user ratings, prices, contact information and more. Read the Google blog on ad extensions here.

At this time, the new mobile carousel ads are only available in the US.
