Google is inviting its publishers to try new experimental feature in AdSense Labs, to test, and provide feedback on features they’re working on.
Auto In-feed native ads
Auto In-feed is a native ad format placed inside your feeds. In-feed ads match the look and feel of your site, providing a better user experience for your visitors.
Experiments: During the beta, we may run experiments on these ad units with the goal to improve earnings and/or user experience. This includes, but is not limited to, occasionally showing text and image ads instead of In-feed ads.
