Appal: A/B Testing & CRO

Appal splits your storefront traffic between real Shopify page templates to show you which version sells more. Each visitor sees a genuine theme template rendered normally—no browser rewrites or page flashes. Test up to five different templates at once, from a single block of copy to complete page layouts. Every visit is tracked and every order is matched back to the template that generated it. Compare conversion rates, revenue per visitor, and average order value side by side, with statistical probability showing how likely your challenger is to beat the control. Target specific audiences by device (mobile or desktop), visitor type (new or returning), country, or traffic source. When testing is complete, declare a winner and roll out the best-performing template to all visitors. No page builder required—just real A/B testing with your existing theme templates.
