Mobile viewers are seeing static image ads overlaid on horizontal YouTube videos as part of a new test. The format could increase ad frequency and offer advertisers a fresh placement, but may alter the viewing experience.
YouTube is piloting a new ad format on mobile devices that places static image ads directly over videos playing in landscape mode. This approach allows sponsored images to appear on part of the screen while the video continues uninterrupted, marking a shift from the platform’s traditional pre-roll and mid-roll video ads.
Early observations indicate these image ads surface approximately every three minutes during playback, making them more frequent than standard video ad breaks. The ads do not pause or replace the content, but instead overlay a portion of the video, potentially increasing ad inventory without fully disrupting the user’s experience.
Google has not yet confirmed whether this feature is limited to a small test group or if a broader rollout is planned. The company has been actively exploring new ad placements to expand monetization opportunities across devices and formats, aiming to integrate advertising more seamlessly into the viewing experience.
For advertisers, this test could open up a new way to reach audiences on YouTube without the need for video creative. However, for viewers, the increased frequency of on-screen ads-even if non-intrusive-could change how long-form content is consumed on mobile devices.
This development comes as YouTube continues to refine its advertising strategy. The platform’s ongoing experiments reflect a broader industry trend toward blending ads into content in less disruptive ways. As seen in related coverage, shifts in ad formats can have significant effects on both advertisers and users; for example, recent changes in Google’s AI-generated search overviews have impacted paid ad visibility, highlighting the evolving landscape for digital advertising.
The new image ad format was first spotted by Hana Kobzova, founder of PPC News Feed, who noted its potential to reshape how advertising appears alongside video content on mobile.
Launched in 2005, YouTube has grown into the world’s largest video-sharing platform, with over 2.7 billion logged-in monthly users as of 2026. Owned by Google, YouTube generated more than $31 billion in ad revenue in 2025, accounting for a significant share of Google’s overall earnings. The platform’s ongoing experimentation with ad formats reflects its drive to maintain growth and adapt to changing viewer habits.
