Estimate based on your numbers. Not a promise — actual uplift depends on baseline speed, market, and traffic quality.

Where do the uplift numbers come from?

Industry studies consistently tie page-load improvements to conversion gains. Deloitte's "Milliseconds Make Millions" reports around +8.4% conversion per 0.1s faster; Amazon observed ~1% revenue loss per 100ms of added latency; Walmart gained +2% conversions per 1s improvement. Pick the uplift that fits your market — absolute percentage points are conservative, relative percentages are used in typical A/B-test reporting.
