A Feed rotates multiple creatives inside a single CM360 tag on a schedule. Traffic the tag once, then keep the creative fresh forever — no re-trafficking, no new insertion orders, no waiting on ad ops.
When to use a feed
You want to swap creative weekly (or daily) in a long-running placement.
You're testing several creatives in one slot and want rotation handled for you.
Your client's ad ops team is slow to re-traffic and you'd rather never ask again.
(If you want text values to vary rather than whole creatives, use DCO versions instead.)
Create a feed
Open Feeds in the sidebar and click New feed.
Set:
Name — e.g. "Q3 rotation"
Type — Display or Video
Rotation — how creatives rotate (e.g. Even)
Resolution — the ad size this feed serves (e.g. 300×250)
Default destination URL — the landing page used when a creative doesn't set its own
Click Create feed, then add creatives of the matching size to the rotation and traffic the feed's single CM360 tag.
Update a live feed
Open the feed and add or remove creatives at any time — the live tag picks up the change on its next refresh. You never touch the tag in CM360 again.
