Carousel ad
Showcase your brand or products in a swipeable image carousel, rendered natively across each Google feed. Tell a story across your images, as each image will be displayed in the order they’re uploaded.
Tip
- You can’t currently use product feeds from Google Merchant Center with carousel ads.
- The cost of carousel ads are the same as single image ads (pay for “interactions” or clicks to expand the ad on Gmail or to your website on YouTube and Discover).
- If at least one card is disapproved, the ad status column will be marked as “Approved (limited)” and within 24 hours it will change to “Disapproved”. This is a known issue and will be resolved soon. The ad won’t serve in this case.

Audio and auto-play defaults
When the video ad is in-view, the ad will follow the below sound-on and auto-play defaults per placement:
- Discover feed: Default muted, default auto-play with WiFi connection
- YouTube Home feed: Default muted, default auto-play
- YouTube In-stream: Post tap sound on, default auto-play
- YouTube Watch Next: Post tap sound on and auto-play
- YouTube Shorts: Default sound on, default auto-play
- Gmail: Default muted, default auto-play
- Google Display Network: Default muted, default auto-play
You can run Demand Gen video ads without sound. The auto-play settings for videos depend on where the ad is displayed. For example, videos on Discover will auto-play but are muted by default. On YouTube, videos will auto-play with or without sound, depending on the placement. You can always use a video without audio regardless of the platform.
Video optimization tips
- Grab attention from your audience: Captivate people in the first 5-10 seconds of the ad with a problem statement and show how your product or service solves it.
- Repeat what you’re offering: Echo the call-to-action in the voiceover or include it in superimposed graphics.
