Ad Impression

An Ad Impression is recorded each time an ad is displayed on a digital property, regardless of whether the user engages with it. Impressions are the foundation of programmatic advertising, serving as the baseline for metrics like CPM, CTR, and viewability. Accurate impression measurement helps advertisers evaluate reach and publishers monitor inventory performance. Ensuring impressions are valid and fraud-free is critical for sustaining trust and maximizing ROI in the digital ad ecosystem.
