- Visitors = 10 000
- Stage 1 conversion = 25
- Stage 2 conversion = 40
- Stage 3 conversion = 30
- Average order value = 65
- Ad spend = 4000
- Through stage 1 = 10 000 * 25/100 = 2500
- Through stage 2 = 2500 * 40/100 = 1000
- Conversions = 1000 * 30/100 = 300
- Overall conversion rate = 10 000 > 0 ? 300/10 000*100 : 0 = 3
- Revenue = 300 * 65 = 19 500
- Cost per acquisition = 300 > 0 ? 4000 / 300 : 0 = 13.3333
- Return on ad spend = 4000 > 0 ? 19 500 / 4000 : 0 = 4.875
- Revenue from a 10% relative improvement = 300 * 0.1 * 65 = 1950
Values are shown to six significant figures here; the arithmetic itself runs on exact fractions and is only rounded where a number is printed.
