Tab Cross Sell helps merchants create product add-on campaigns for product pages, cart pages, and compatible cart drawers. Merchants choose candidate pools, so recommendations stay within approved products. Fixed and rotating strategies manage exposure within each pool. The app measures valid impressions, clicks, add-to-carts, direct and assisted attributed revenue, and refund clawbacks. Theme app extensions install without theme-code edits and fail closed if recommendations are unavailable.

• Control every candidate pool with Shopify's native product picker.
• Show add-ons on product pages, cart pages, and compatible cart drawers.
• Measure direct and assisted revenue with automatic refund clawbacks.
• Keep every recommendation inside merchant-approved candidate pools.
• Track impressions, clicks, add-to-carts, and revenue per impression.
