Lift in Conversion Rate measures the percentage increase or improvement in conversion rate between two different variations or time periods, indicating the effectiveness of a change or campaign.
How to Calculate Lift in Conversion Rate
Calculate lift by comparing the conversion rates of the test and control groups, expressed as a percentage increase.
- Identify conversion rates: Determine the conversion rate for both baseline (control) and test groups.
- Calculate lift: Use the formula to find the relative increase.
Formula example: If the control group conversion rate is 8% and the test group conversion rate is 10%, then lift = ((10% – 8%) ÷ 8%) × 100 = 25% lift.
