Opt-in trials 15–25%, opt-out higher with churn attached, freemium 2–5% to paid. Compare within motion, not across. Defaults (1,000 visitors → 100 signups → 20 paid at $29) give 10.0% visitor→signup, 20.0% signup→paid, 2.0% overall, $580 MRR — with 3 presets (Typical SaaS, High conversion, Early stage) and CSV export.
Signup friction, empty-state confusion, and missing onboarding emails top the list. Instrument each step before optimizing.
Activated trials (key action done) convert 3–5x unactivated ones. Optimize activation first — conversion follows.
