How this free tool works

Purchase conversion is purchases divided by sessions; cart-to-purchase and checkout-to-purchase rates are also calculated. Counts must follow a consistent reporting period and must not increase at later stages. The diagnostic asks you to confirm clear shipping, mobile usability, payment methods and return policies; recommendations are based on your answers, not remote tracking.

Worked example

With 1,000 sessions, 150 cart additions, 75 checkouts and 30 orders, the purchase conversion rate is 3%, with 60% checkout abandonment.

Limitations and data quality

These are user-reported counts; no GA4, Shopify analytics, browser network inspection, checkout purchase test or guaranteed uplift. Different analytics definitions can create incompatible funnel counts.
