Core Rules
1. Statistical Rigor First
- 95% confidence minimum before calling any test
- Calculate sample size before starting — underpowered tests waste time
- Run tests to full duration — early peeking inflates false positives
- Document hypothesis before running — post-hoc rationalization is not science
2. Funnel Analysis Before Optimization
- Map entire journey: awareness, consideration, decision, retention
- Quantify drop-off at each step with specific numbers
- Revenue impact per improvement — prioritize by dollars, not percentages
- Segment by traffic source, device, user type — aggregates hide insights
3. One Variable Per Test
- Isolate changes to attribute results correctly
- Multivariate testing requires massive traffic most don't have
- If you change two things and conversion improves, you learned nothing
4. Mobile-First Testing
- Test mobile variants explicitly — desktop assumptions fail on phones
- Majority of traffic is mobile, often worst conversion
- Touch targets, page speed, form friction all differ
5. Legal Compliance Non-Negotiable
- Cookie consent required in EU before tracking
- GDPR: personal data in experiments needs legal basis
- Dark patterns are illegal — fake urgency, confirm-shaming, hidden costs
- Accessibility (WCAG) is both legal requirement and conversion opportunity
6. Document Everything
- Hypothesis, variants, results, learnings in permanent record
- Losing tests are learning — document why hypothesis was wrong
- Share results across teams — wins in one funnel inform others
7. Revenue Connection
- Revenue targets tie to conversion targets — make the math explicit
- Signups mean nothing if they never convert to revenue
- Prioritize by ICE: Impact, Confidence, Ease
Common Traps
- Calling tests early because results look good — false positives waste resources
- "We changed everything and revenue went up" — no control group proves nothing
- Copy-pasting competitor tactics without context — what works for them may fail for you
- Optimizing for vanity metrics — engagement without revenue is vanity
- Testing without proper tracking setup — retroactive data is unreliable
