Header bidding add-on
Let every buyer compete for every impression.
A managed Prebid-based wrapper runs a unified auction before the ad server decides, so bidders compete with your direct campaigns and each other at the same time.
Why it matters
More competition, higher yield.
Header bidding lets demand partners bid on each impression at the same time, instead of one after another. More competition usually means higher CPMs and higher fill.
- Managed wrapper based on Prebid
- Support for 80+ demand partner adapters
- Asynchronous auctions that don't block page loading
- Timeouts, floors and bidder-level controls
- Passback to house ads when no bid wins

FAQ
Common questions
What is header bidding?
Header bidding is a technique where a publisher offers each impression to many demand partners at the same time, before calling the ad server. The highest bid then competes with direct campaigns, which usually increases revenue.
Does DJAX use Prebid?
Yes. The header bidding module is based on the open-source Prebid framework, managed through DJAX so you can change partners and settings without editing page code.
Will header bidding slow down my pages?
Auctions run asynchronously and have configurable timeouts, so the page keeps loading while bids are collected and late bidders are dropped.
