About Prebid.js
Prebid.js is the open-source header bidding library used by most managed partners under the hood. Publishers with ad-ops capacity run it themselves with Google Ad Manager and direct contracts with SSPs (Magnite, PubMatic, Index Exchange, OpenX and others), keeping the managed partner's 10-25%. Worth it from a few hundred thousand pageviews if you have the skills.
Pros
- Keep 100% of the auction; full control over bidders and floors
- Industry standard with 300+ bidder adapters
Cons
- Needs ad-ops skill, Google Ad Manager and direct SSP contracts
- SSPs each have their own minimums
