OpenRTB
OpenRTB is an IAB Tech Lab protocol that standardizes how programmatic buyers and sellers exchange bid-request and bid-response information for real-time advertising transactions.
A shared protocol reduces custom integration work and gives independent platforms a common vocabulary for inventory, devices, media formats, deals, supply-chain information and bidding.
How it works
- The seller sends a structured bid request.
- The buyer evaluates the request and can return a structured bid response.
- Media, price, deal and tracking fields follow agreed protocol semantics.
- Implementations still apply their own business, privacy and quality policies.
Frequently asked questions
Is OpenRTB a company or platform?
No. OpenRTB is an interoperability protocol used by many independent ad-tech platforms.
Does using OpenRTB guarantee auction quality?
No. The protocol standardizes communication; platforms still need their own validation, fraud controls, privacy rules and commercial policies.
