Ad network vs ad exchange

An ad network packages inventory for buyers. An ad exchange provides transaction infrastructure connecting supply and demand. A business can perform both roles.
Compare responsibilities rather than labels
An ad network commonly packages or represents inventory for buyers. An ad exchange provides a marketplace mechanism for transactions between supply and demand. An ad server manages delivery decisions and reporting. One organization can combine several responsibilities.
The useful selection question is who handles each part of your actual workflow: demand access, inventory eligibility, creative delivery, reporting, commercial disputes and settlement. A product category alone does not answer those questions.
Ask the same questions of each candidate
Use a dated evaluation sheet. Mark missing information unknown rather than replacing it with a favorable assumption. Ask for evidence that applies to your environment, not just a platform-wide feature list.
| Question | Evidence to request | Why it matters |
|---|---|---|
| Who supplies demand? | Current eligible buyer or partner terms | A protocol interface is not buyer access |
| Who renders the creative? | Supported integration and runtime tests | A bid response is not a working placement |
| Who defines payable revenue? | Fee basis, adjustments and payment policy | Gross reporting may differ from payable revenue |
| Who resolves problems? | Support and dispute process | Operational ownership must be clear |
Work through one hypothetical publisher decision
Consider a small publisher with one website and limited engineering capacity. A managed integration might reduce day-to-day operational work, but eligibility, controls and commercial terms still need verification. A publisher with dedicated ad operations may instead value more control over delivery and demand relationships.
Neither workflow is inherently better on revenue. Run a controlled trial with comparable traffic, document integration effort, and measure user experience. Reject a comparison that uses different traffic mixes or treats a promotional earnings claim as a reproducible result.
Where ADX fits in an evaluation
Use the ADX availability documentation to distinguish source packages, distribution and runtime evidence. Review publisher disclosures separately from the protocol explanation. This guide does not rank ADX above another platform or imply feature parity with Google Ad Manager, mediation systems or managed publisher services.
Google Ad Manager is included as an example of a platform that can manage multiple networks and exchanges. That example illustrates overlapping roles; it is not an endorsement or a pricing comparison.
