The auction begins with available inventory
Every advertising auction begins with an opportunity to display an advertisement. The opportunity may be associated with a website, page, placement, format and other signals.
That opportunity represents supply. Advertisers represent demand.
Campaign eligibility
Before comparing bids, the marketplace must determine which campaigns are eligible. A campaign that does not match the requirements of an opportunity should not be allowed to compete simply because its bid is high.
- Campaign is active
- Campaign has available budget
- Targeting requirements are satisfied
- Inventory is compatible with the campaign
- Marketplace rules are satisfied
Bid comparison
Once eligible campaigns have been identified, their bids can be evaluated. The marketplace needs a consistent way to compare competing demand.
The highest nominal bid is not necessarily meaningful if the campaign is ineligible or otherwise fails marketplace requirements. Eligibility comes first; competition comes after.
The winning bid
The winning result represents the campaign selected for the available advertising opportunity. The ad can then be delivered according to the marketplace's serving process.
Why auction transparency matters
Auctions work best when participants understand the rules. Advertisers need predictable campaign behavior, while publishers need confidence that their inventory is being competed for fairly.
Transparency is therefore not just a reporting feature. It is part of marketplace design.
From impression to revenue
The auction is only one part of the complete marketplace lifecycle. After the winning decision, the resulting activity can contribute to advertiser spend, publisher revenue and marketplace reporting.
