Google AdWords Tests New Hotel Ad Booking Format
Moz reports on Google+ that Google is testing yet another AdWords format, this one around nearby hotels.
Here is a search for [boca raton resort] that normally brings up a carousel at the top of the page but here, it shows a knowledge graph ad box with the ability to book directly in the box.
Google is often testing user interfaces and it is fun to follow them.
