Google is currently testing a new visual ad format that adds an extra layer of interactivity – the Double Expand Swipe Carousel.
This format allows users to not only swipe through images in the standard carousel view but also tap on any image to open a larger, expanded carousel view. This creates a more immersive experience, especially on mobile devices, where every inch of screen space matters.
Two Levels of Interaction in One Ad
Here’s how it works:
- When the ad appears, users can swipe through the images as they normally would in a typical carousel format.
- If they tap on any single image, it opens into a larger carousel where they can continue swiping left or right – but now in a bigger, more prominent layout.
This dual-layer approach enhances the ad’s visual impact and can help capture more attention in crowded mobile environments.
How It Looks in Action

Why This Matters
If your campaigns rely heavily on visuals – such as in fashion, food, travel, interior design, or beauty – this new ad format could:
- Increase user engagement
- Extend interaction time with the ad
- Potentially boost click-through rates
At the time of writing, this format seems to be in limited testing and isn’t available to all advertisers yet. However, it’s a clear signal that Google is continuing to innovate in the area of interactive ad formats.
The Double Expand Swipe Carousel is an exciting development for advertisers who want to maximize the visual power of their campaigns. While it’s still in testing, it’s definitely something to keep on your radar – especially if you’re focused on high-impact mobile advertising.
