Google’s Question/Answer – What do text ads look like in the mobile-first world?
Mobile has revolutionized the canvas where ads live. Earlier this year, we removed right-hand side ads on desktop to improve the search experience and make it more consistent across devices. This paved the way for us to introduce the biggest changes to our text ads since AdWords launched fifteen years ago.
Optimized for screen sizes of the most popular smartphones, new expanded text ads in AdWords provide more ad space so you can showcase more information about your products and services before the click.
