Entry template:

• Definition — plain-English summary.
• Why it matters — impact on revenue, cost, or risk.
• How to measure — formula or method (when applicable).
• Use Cases — concrete scenarios (e.g., testing email subject lines to lift opens; comparing landing page layouts to increase sign-ups; evaluating product descriptions to boost sales).
• Tips — actionable best practices (e.g., test one variable at a time; use sufficient sample size; run tests long enough to smooth variability).
• Common Pitfalls — traps to avoid (e.g., unclear goals/metrics; stopping tests too early; ignoring external factors during the test window).
• Related terms — cross-links for deeper context.

Conventions: Short examples, explicit attribution models (e.g., last-click, data-driven), formulas shown like AOV = Revenue ÷ Orders. No unverified benchmarks.

How to use: Browse A–Z or by category, follow cross-links, and use formulas and checklists as quick references. Not legal or accounting advice.
