Expandable ads on the Google content

Expandable ads on the Google content network are designed to automatically expand in the direction where the most space is available on the screen. They must be clicked by the user to expand and contract.

These features help create a positive experience for users and provide advertisers with more accurate ad engagement metrics by avoiding expansions triggered by accidental mouse-overs. Expandable ads can also help AdSense publishers by engaging users on their sites with more ad variety and opportunities to interact with the ad content.

For now, expandable ads will be available as a limited beta test in the U.S. to advertisers and agencies participating in their 3rd Party Ad Serving program. Stay tuned for future updates as Google expand their test.
