Frequently Asked Questions

How do I calculate the revenue impact of a CRO win?

Annual revenue lift = monthly visitors × (new CR - baseline CR) × AOV × 12. Example: 50,000 visitors × (2.5% × 0.15 = 0.375% lift) × $85 AOV × 12 = $19,125/year. This calculator handles the math; you supply traffic, baseline CR, observed uplift %, and average order value.

What AOV should I use in the revenue impact calculation?

Use the AOV of the segment that completes the conversion event you tested. If you tested a checkout page, use checkout AOV (not store-wide AOV including browsers). If you tested a signup page that converts to free trial, use 30-day trial-to-paid AOV × paid conversion rate.

Should I include incremental traffic in my CRO revenue calculation?

No — assume flat traffic. CRO wins compound on existing visitors; if you're forecasting with growing traffic, multiply the result by your expected growth multiplier separately. Keeping CRO + acquisition separate makes attribution honest and prevents double-counting.

Why is my CRO revenue lift smaller than expected?

Three common causes: (1) Sample-population effect — your test winner only converts the people who would have converted anyway, plus a few marginal. Look at segment-specific CR shifts. (2) Cannibalization — fewer conversions on adjacent products. (3) Halo decay — uplift fades over 30-90 days as novelty wears off. Conservative forecast: discount the calculated lift by 20-30%.

How long until I see the calculated CRO revenue lift?

The calculator assumes the lift is realized immediately at full strength and held for 12 months. In practice: month 1 ≈ full lift, month 6 ≈ 80-90%, month 12 ≈ 70-85% (depending on freshness decay). For lasting wins (like checkout flow fixes), use the full annual number. For aesthetic-only wins (novelty banners), discount 30%.
