Holdouts & Incrementality

note

Holdouts and incrementality testing are an enterprise feature available as part of Marqo Enterprise. Contact your Marqo account manager to enable this feature.

A holdout is a group of shoppers who never receive a change, kept stable over time so you can measure the true incremental impact of everything else you ship by comparing against them.

Marqo does not currently offer persistent holdouts, geo-holdouts, or switchback tests as a configurable feature. The measurement tool available today is A/B testing: tests are created in the merchandising console with a traffic split per variant, and results are read from analytics using the pixel_experiment labels described in the Analytics API.
