Questions
Why are so few benchmarks published?
The channel opened to self-serve advertisers only in 2026, and most advertisers keep results private.
Can we share our benchmarks with you?
We publish only anonymised, aggregated figures with clients' permission.
How often is this page updated?
Monthly, or sooner when a significant source appears.
How to read early benchmarks
Most published AI ad figures come from agencies summarising their own accounts, from single pilots or from small analytics samples. They're useful for planning ranges and sanity checks. They're not reliable predictors for a specific category, country or offer.
