Header bidding without changing your wrapper

Publishers that already run Prebid.js can add bid9 as one more bidder. The bid9 adapter sends a single OpenRTB 2.6 request per auction and returns bids for every ad unit on the page.

This page runs a real Prebid auction against the local bid9 mock endpoint, alongside AdKernel, a second Prebid bidder. The leaderboard and sidebar are bid9 only. This in-article unit has bid9 and AdKernel competing, and bid9 bids lower here, so AdKernel wins it. Each winning creative is rendered with pbjs.renderAd, and the badge under each slot names the winning bidder.

Floors from the Price Floors Module, consent signals, the SharedID user ID and the supply chain object are all forwarded automatically. Use the "Last bid request" link to inspect the exact payload the mock received.

Change the placement IDs in the URL to try other mock scenarios, for example ?side=deal for a deal bid, ?top=nobid for an empty slot or ?inline=slow&timeout=600 for a timeout.
