SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve? Teams guess why visitors don't convert and waste traffic on meek tweaks like button colors. This Skill replaces guesswork with a research-driven methodology that discovers real visitor objections and turns them into prioritized, statistically rigorous experiments. ## Core Features & Use Cases - Conversion Audits: Score any landing page or funnel against a 7-row quick diagnostic covering value proposition clarity, proof placement, and funnel mapping. - Objection/Counter-Objection Framework: Build O/CO tables from exit surveys, chat logs, and support tickets, placing counters at the exact point of friction. - Hypothesis & Test Design: Prioritize experiments with ICE scoring and run A/B tests with proper sample sizes, full business cycles, and 95% confidence. - Use Case: A SaaS team with high signup-page bounce uses the Skill to run exit surveys, discover a trust objection, add named testimonials with specific results near the CTA, and validate the lift with a properly sized A/B test. ## Quick Start Audit my landing page for conversion issues and propose three research-backed A/B test hypotheses with ICE scores.

Frequently Asked Questions about cro-methodology

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I find out why visitors are not converting on my landing page?

Run exit-intent surveys asking what stopped visitors, analyze live chat logs and support tickets for recurring hesitations, and watch session recordings for rage clicks and drop-offs. Quantitative analytics shows where problems are; qualitative research shows why.

What is an objection counter-objection table in CRO?

An O/CO table maps each visitor objection to a specific evidence-backed counter-objection placed where the concern arises. It covers the Big 5 objections: trust, price, fit, timing, and effort, using testimonials, guarantees, and case studies as proof.

How long should an A/B test run before calling a winner?

Run at least one full business cycle, typically one to two weeks covering weekdays and weekends, with a pre-calculated sample size. Never peek and stop early, since that inflates false positives even at 95% confidence.

When should I use multivariate testing instead of A/B testing?

Use multivariate testing only with 100k+ monthly visitors on an already proven winning page. A/B testing suits bold conceptual changes and lower traffic, while multivariate isolates individual element contributions at high volume.

Why do small A/B tests like button color changes usually fail?

Small changes produce effects too tiny to detect without massive sample sizes, so they rarely reach significance. Bold changes like new value propositions or redesigns can plausibly double conversion and are detectable with far less traffic.
