How does the Carousel work?

The Demand Hub carousel displays multiple creatives within a single ad experience. Depending on the campaigns and demand sources available, the slides may feature creatives from the same advertiser or different advertisers.

Yes. A carousel can display multiple creatives from the same advertiser or from different advertisers, depending on the campaigns and demand sources available.

This flexibility allows Demand Hub to optimize monetization opportunities while delivering an engaging ad experience.

How do ad requests work?

Demand Hub does not send a new ad request every time the carousel moves to another creative. For each request received from the publisher, Demand Hub sends one ad request for two bids to its SSP seats.

• The format is only triggered when the ad unit is in view and our attention prediction indicates sufficient user attention.
• No ads are served through the carousel while the placement is out of view.
• Each creative is billed only when it is actually displayed on screen.
• On average, we observe approximately two creatives per slot across the network.

We intentionally limit rotation because excessive rotation can negatively affect advertiser performance and long-term publisher yield.

Are publisher floors still respected?

Yes. Publisher floor strategies are applied to every ad according to the publisher request, including when dynamic flooring is used. The carousel does not bypass or invalidate the publisher's pricing strategy.

Does the carousel create additional latency?

The format is designed to protect both user experience and publisher inventory.

Demand Hub focuses on highly viewable placements, such as sticky units, and makes one call for the full carousel rather than repeated calls for each slide.
