Prebid Adapter
The ezoic bidder lets you add Ezoic demand to header bidding you already run. Ezoic competes in your auction like any other bidder: behind one bid request it runs its own demand (server-side partner bidders, Google demand, and Ezoic direct demand) and returns its single best bid per impression. Your auction picks the winner and your ad server renders it as usual.
| Bidder code | ezoic |

| Media types | Banner (standard, interstitial, rewarded), video, native |
| Inventory | Web and app |

| Bid params | None required. placementId (string) is optional. |
| Pricing | Bids are net to you: Ezoic's revenue share is applied before the bid enters your auction. |
The bidder is listed on docs.prebid.org.
Before you start
- Register your inventory. Every domain and app bundle must be registered and approved by Ezoic before it receives bids. Unapproved inventory gets no-bid responses, not an error. Send your list to prebid@ezoic.com or your Ezoic contact.
- Publish ads.txt / app-ads.txt. During onboarding Ezoic gives you the entries that authorize its demand partners for your inventory. Buyers check them, so publish them before expecting meaningful bid rates.
- Allow vendor 347 in your CMP if you collect TCF consent.
- Payment and reporting are set up with your Ezoic contact during onboarding.

placementId
placementId is an optional string you can attach to any ad unit, for example the name you use for the slot. Ezoic records it with each request for reporting and troubleshooting. It does not change how the slot is bid on: Ezoic works out the placement type and position from standard signals and its own slot data.
