¿Cuál es el uso de una URL de impresión de terceros en Amazon DSP?

A third-party impression URL, also known as a 1x1 tracking pixel or impression tracker, is used to verify campaign statistics with an external vendor. When an ad is served, this URL is called, allowing the third-party provider to independently count impressions and, in some cases, measure viewability. This provides an unbiased verification of the data reported by Amazon DSP, ensuring transparency and accuracy for advertisers. Creating custom audiences is typically done through pixel implementation or data onboarding, not impression URLs. Generating creative content is a design and production task, separate from ad tracking.
