REDS viewability and post-events feed columns

Post-bid viewability and post-bid verification are measurements taken after an ad is served to a user following a successful bid in programmatic advertising. Here's a summary of these two measurements:

Post-bid viewability: Measures how often an advertisement served to a user is viewable.
Post-bid verification: Builds on viewability by assessing additional quality signals, such as brand safety, fraud detection, and ad clutter, to ensure the ad placement met performance, integrity, and compliance standards.

Together, these measurements help advertisers confirm that impressions were not only served but also met the visibility and quality expectations of their campaigns.

Here's what you need to know about the viewability and post-events feed columns:

Some metrics, such as the Quality Alliance (QA) metrics, overlap with other provider feeds.
Certain fields in this feed might be modified to comply with regional regulations. For data scrubbing and retention details, see REDS data practices.

The following sections list the available viewability metrics by provider in the order in which they appear.
