Conversion rate
Enter visitors and conversions to see your rate.
Ranges are illustrative context, not benchmarks or predictions. Two numbers can't tell you whether a change caused a difference — that needs a controlled test with enough conversions.
How it's calculated
Conversion rate = conversions ÷ visitors × 100. Visitors must be a whole number greater than zero, and conversions a whole number between zero and the number of visitors.
Use the same definitions every time
- Pick one visitor measure — sessions or unique visitors — and stick to it.
- Count one kind of conversion: orders, sign-ups or add-to-carts, not a mix.
- Compare the same date range and traffic source when you compare pages.
What a single rate can't tell you
A rate describes what happened; it doesn't explain why. To know whether a new page beats your old one, send the same traffic to both at the same time and wait until each has enough conversions. Our guide on pre-sell pages vs product pages walks through a fair test.
