Data

    Advertising Benchmarks

    A benchmark hub for AI advertising: the metrics that matter, how they are measured, and how AdArena tracks them across live challenges.

    Overview

    Benchmarks that matter in AI advertising

    Six metrics that separate an ad that looks good from an ad that performs.

    Hook Rate

    Percentage of viewers who watch past the first 3 seconds. The single biggest predictor of AI video ad performance.

    Retention

    Percentage of the ad watched on average. High retention correlates with strong storytelling and pacing.

    CTR

    Click-through rate from impression to landing page. A weak hook depresses CTR before the offer even lands.

    CPA

    Cost per acquisition. The bottom-line efficiency measure — media cost divided by conversions.

    ROAS

    Return on ad spend. Revenue generated per dollar of media, blended or by variant.

    Usable Ad Rate

    The share of submissions in a challenge that pass brand-safety, legal, and craft review. An AdArena-native benchmark.
