Conversion rate optimization

As @Lisabraker asked about CRO and as @cagenicolus and @kpkarthik observed, conversion work is less about tricks and more about a repeatable process that improves business outcomes. The paragraphs below add a practical workflow, common prioritization methods, experiment hygiene, and quick troubleshooting pointers that build on those replies.

A practical CRO workflow:

1. Define the primary business conversion and 1–2 supporting micro-conversions.
2. Instrument analytics and map the funnel to find high-drop pages.
3. Gather qualitative signals (session recordings, on-site surveys, user tests) to explain the “why.”
4. Turn insights into clear hypotheses (what changes, why it should move the metric).
5. Score and prioritize ideas, then run controlled experiments on the highest-impact pages.

Prioritization and what to test first: use objective frameworks (PIE, ICE or similar) to balance potential lift, importance and ease—this prevents chasing low-impact ideas and helps allocate scarce traffic to the right pages. For low-traffic properties, focus on larger-impact changes (pricing, value proposition, checkout flow) or on improving upstream traffic quality. Conversion PIE explanation (conversion.com)

Experiment hygiene and common traps: calculate sample size and planned duration before launching; stopping early (“peeking”) inflates false positives and yields unreliable winners. Tests should usually span full weekly cycles and hit the precomputed sample per variation. Track primary business metrics (not vanity lifts) and segment results (device, source) before deciding. Evan Miller’s sample-size tools and notes explain these risks and calculations. Evan Miller sample-size tool. (evanmiller.org)

Quick wins and cautions: prioritize mobile-first fixes, clear CTAs and removing form friction; document every test, its hypothesis and outcome; resist shipping a “win” without implementation and monitoring.
