or
- To create custom audiences
- To verify campaign metrics with a chosen measurement partner
- To generate creative content
Explanation
A third-party impression URL is used to send impression activity to an approved external measurement system. In Amazon DSP, this supports independent validation of delivery metrics outside Amazon Ads reporting. The URL typically functions as a tracking pixel or measurement tag attached to eligible creative. This helps reconcile campaign reporting with a selected third-party ad verification or measurement provider.
Why the other options are incorrect
Custom audiences is incorrect because impression tracking URLs do not build audience segments.
Creative content is incorrect because impression tracking URLs measure ad delivery rather than generate creative assets.
