How to Calculate Ecommerce Conversion Rate?
Ecommerce conversion rate = (completed transactions divided by total sessions) multiplied by 100. In Shopify Analytics, go to Reports and then Conversion. In GA4, set up a purchase event as a key event and divide conversions by sessions for your chosen date range. The blended rate is a starting point, not a diagnostic tool. Segment by device (desktop vs mobile), traffic source (organic, paid, email, direct), and new vs returning visitors before deciding where to focus optimization work.
