Capturing audience attention is the key to success, but how do brands measure attention effectively in 2025? Enter Attention Units (AU), a metric that provides deeper insights into how engaged audiences truly are with an ad.

What Are Attention Units (AU)?

According to the Interactive Advertising Bureau (IAB), Attention Units (AU) are a standardized measure that quantifies user engagement based on factors such as time-in-view, gaze tracking, and interaction rates. Unlike traditional viewability metrics, which only measure whether an ad is visible on a screen, AU dives deeper into whether a user is actively paying attention.

The IAB’s Guide to Attention Measurement highlights AU as a key factor in understanding consumer engagement and optimizing ad placements. Research from the Attention Council also supports the importance of AU, revealing that ads with higher attention scores drive up to 30% greater brand recall and 20% higher conversion rates compared to standard viewability-based ads.

How AU Works

AU takes into account multiple engagement signals, including:

  • Ad duration & screen time – How long an ad is viewed in an active state.
  • User interaction – Clicks, swipes, hovers, or other engagement behaviors.
  • Eye-tracking & focus-based metrics – AI-driven analysis of where users' eyes focus on an ad.

By combining these factors, AU provides brands with a more precise measure of audience engagement, allowing them to optimize their media spend toward placements that truly capture consumer attention.
