Conversion Rate Optimization

Q: How do I know the Conversion Rate Optimization output is good?

The skill verifies itself against its own quality checks: The audit cites a specific issue per heuristic, not a generic checklist tick; Test ideas are hypotheses tied to a diagnosed blocker, prioritised by ICE; Each test states the sample size/duration to detect the expected lift; Low-traffic reality is acknowledged — A/B testing is only recommended when volume supports it.

Audit a landing page or funnel step and produce a prioritised CRO test plan. Use when asked to improve conversion rate, audit a landing/signup/checkout page, reduce funnel drop-off, or plan A/B tests for a page. Produces a CRO plan — a heuristic conversion audit, the diagnosed friction, prioritised test hypotheses (ICE), test designs with sample-size math, and the measurement guardrails.

What to give it

▸The page / step & its one goal — the single action it should drive (signup, purchase, demo).

▸Current performance — conversion rate and traffic volume (volume decides whether A/B testing is even viable).

▸The audience & their intent — where they come from and how warm they are.

▸Known data — analytics, session recordings, or survey signals on where people drop or hesitate.

✅ The bar it holds itself to

Every skill in this library self-verifies — these are this skill's own quality checks, straight from its definition.

✓The audit cites a specific issue per heuristic, not a generic checklist tick

✓Test ideas are hypotheses tied to a diagnosed blocker, prioritised by ICE

✓Each test states the sample size/duration to detect the expected lift

✓Low-traffic reality is acknowledged — A/B testing is only recommended when volume supports it

✓Guardrail metrics prevent a local conversion win that harms downstream value

⚠️ What it refuses to do

Do not test trivial cosmetics (button colour) before fixing clarity, friction, and anxiety — the big levers

Do not A/B test on traffic too low to ever reach significance — use qualitative research or sequential changes instead

Do not optimise the step in isolation — a signup lift that lowers paid conversion is a loss; watch the downstream metric

Do not call a test on day two because it looks good — set the threshold and sample size before you start

Do not redesign by opinion — every change should trace to a diagnosed blocker and a hypothesis
