Reviews summary

Holdout - A/B Testing & CRO allows ecommerce merchants to A/B test their storefront changes without editing theme files. The app helps users describe the changes they want, preview different versions, select the audience and goal, and launch tests. Holdout measures key metrics like conversion rate, revenue per visitor, add-to-cart, and order value, applying the winning version as a runtime rule that can be rolled back. However, there are not enough reviews to analyze at the moment.

Holdout makes A/B testing much easier for us. We can test different storefront ideas without making unnecessary theme changes, and the results help us make better decisions. Very useful app overall.

Really useful tool for improving our Shopify store. The testing process is simple, and the performance metrics make it easier to understand what actually works. I also like being able to roll back experiments when needed. Highly recommended!

A very useful testing solution for Shopify. I particularly like being able to preview both versions, select the audience and define the conversion goal before launching a test.

Great experience with Holdout. The fact that tests run without changing the theme gives us confidence when experimenting with different storefront ideas.

Holdout makes A/B testing much easier to manage. We can test storefront changes without modifying our theme files, which makes the process much safer and more convenient.
