Introducing the next breakthrough in omnichannel measurement: Smart Holdout Groups from Blis

Disconnected channels create disconnected insights
Why compromise your results?
Traditional measurement is broken, and the ad industry has been making do with siloed, manual and resource-heavy measurement. But why settle for incomplete insights into the effectiveness of your omnichannel campaigns?
Measure the collective impact of your omnichannel campaign across one unified audience
Why Smart Holdout Groups?
Smart Holdout Groups uses machine learning technology to create statistically balanced target & control groups of zip codes at the click of a button. Its patent-pending methodology, rooted in geography, enables omnichannel measurement to be conducted with unprecedented accuracy and scale, without relying on cookies or IDs.
This allows advertisers to measure impact across all channels, even those that were previously disconnected like DOOH, Audio and CTV.

How does it work?
Our algorithm takes your audience and looks at factors such as demographics and income to create statistically balanced groups at the zip code level. It also solves for human behavior like commuting by taking into consideration how your audience moves between zip codes.
Smart Holdout Groups technology then creates buffer zones where ads are not served or measured, in between the Target and Control groups, to prevent cross-pollination.
