Play videos in-line on iOS

To improve ad performance and provide a better viewing experience, Google Ad Manager publishers require the playsinline attribute for all in-banner videos. This attribute ensures that in-banner video creatives do not expand to full screen without user action.

Starting in June 2019, all HTML5 creatives with in-banner videos that are missing the playsinline attribute will be filtered from Display & Video 360 auctions. To make sure your creatives are eligible for bidding, always enable in-line playback for all in-banner videos.

Note: The webkit-playsinline attribute is not supported. Make sure to only use the playsinline attribute.

How to turn on in-line playback

Google Web Designer

All creatives built with Google Web Designer after March 14, 2019 (Version automatically include the required attribute (playsinline). If your creative was built before this date, update to the latest version of Web Designer, then open and republish your creative.


Add the playsinline attribute to every video element in your HTML. This is a Boolean element, so adding the playsinline attribute on its own is the same as setting it to true.
<video id="video1" controls="controls" poster="image.jpg" playsinline>
   <source type="video/mp4" src="video.mp4" />
   <source type="video/ogg" src="video.ogg" />
   <source type="video/webm" src="video.webm" />

YouTube player

If you're using the YouTube player with Google Web Designer, follow the Web Designer steps above to update creatives, if necessary.
If you're using the YouTube player API, add the playsinline player parameter.
