Conversion Rate Formula

Conversion Rate % = (Total Completed Orders / Total Website Visitors) × 100; Additional Revenue = (Target Orders - Current Orders) × AOV
  • Total Website Visitors: Unique visitor sessions arriving on your online store.
  • Completed Conversions: Successful checkout purchases placed.
  • Conversion Rate %: Percentage of traffic that successfully completes a purchase.
  • CRO Revenue Upside: Revenue generated by boosting conversion rate without buying more traffic.

      Frequently Asked Questions

      What is the fastest way to increase e-commerce conversion rate?

      Implementing express checkouts (Shop Pay, Apple Pay, PayPal 1-click), adding customer reviews on product pages, displaying clear shipping times, and removing hidden surprise fees at checkout.

      How does mobile conversion rate compare to desktop?

      Mobile traffic typically accounts for 70%+ of store visits but converts at roughly half the rate of desktop (e.g. 1.8% mobile vs 3.5% desktop) due to small screens and checkout friction.
