# CRO — Conversion Rate Optimization **Experimentation/improvement skill for raising conversion on a limited surface (landing page, form, checkout screen).** Whole-funnel diagnosis is mkt-funnel-audit; experiment design procedure is mkt-ab-testing. ## 5-Dimension Page Audit (priority order) 1. **Message-market fit** — does the headline match the visit's intent source (ad copy, search intent)? The biggest lever is the message, not the design. 2. **Value clarity** — the 5-second test: if you can't tell what you get here or why you should do it here, it fails. The hero is "what + who + why now". 3. **Friction** — number of form fields, required info, unexpected costs, forced account creation, slow LCP (drop-off spikes past 3 seconds). 4. **Trust signals** — concrete numbers, real customer counts, guarantee policies, reviews. Abstract superlatives ("the best") are worthless. 5. **CTA** — one primary CTA per screen, starts with a verb, reverses risk ("start free, no card"). ## Prioritization Rank by ICE (Impact × Confidence × Ease, each 1~10). But: - Subjective scores with no confidence evidence are capped at Confidence ≤5 - Message-vs-message tests (copy) are low risk so run first; layout and structure changes come later - Below 1000 sessions/month, A/B tests are meaningless — ship the change and compare before/after instead ## Output ``` # CRO Audit — {URL/screen} ## Verdict (3 lines + #1 conversion bottleneck) ## Audit table (dimension | issue | severity | evidence) ## T
