Zinx Signal is an A/B testing app for Shopify stores. Merchants can split traffic between two or more versions of a theme, template, page content, style, or redirect and see which version leads to more revenue, not just more clicks. The app installs from the Shopify admin as a theme app extension, with no code to edit. Orders are attributed to the version that earned them, and refunds are subtracted, so the result reflects revenue rather than surface engagement.

• Test headlines, pages, templates, or full themes against each other.
• Split traffic between two URLs to see which one performs well.
• Test design or script changes without editing your theme code.
• Results shown in revenue and profit per visitor, refunds included.
• Choose a probability-based view or a fixed-sample-size comparison.
