cro-optimization
Run conversion rate optimization through hypothesis-driven testing including audit, hypothesis generation, test design, statistical analysis, and rollout decisions. Use this skill whenever the user wants to optimize conversion, run A/B tests, audit a funnel, generate test hypotheses, design experiments, or analyze test results. Triggers on conversion optimization, CRO, A/B test, split test, multivariate test, hypothesis, conversion funnel, funnel audit, experiment design, statistical significance, lift, optimization. Also triggers when the user has a conversion problem and isn't sure where to

# CRO Optimization Run conversion rate optimization as a structured discipline: audit → hypothesize → test → decide. Stack-agnostic. Tool-agnostic. This skill is for running tests against existing pages and flows. For writing landing page copy from scratch, use `landing-page-copy`. For setting up the analytics that make CRO possible, use `analytics-strategy`. --- ## When to use - Converting traffic at lower rate than expected - Specific funnel step has high drop-off - Pages with high traffic that could move the needle if optimized - A/B testing infrastructure exists (or can be set up) - Statistical significance and sample size questions ## When NOT to use - Without sufficient traffic to test (under ~5,000 monthly conversions per variant) - Pre-launch (no users to test on yet) - Strategy or messaging-level questions that need qualitative research first - Brand-defining choices (CRO can't optimize a fundamentally wrong brand) --- ## Required inputs - The page or flow under optimization - Current conversion rate and traffic volume - Access to analytics (event tracking, funnel data) - An A/B testing tool (or willingness to set one up) - Time and budget for testing (typically 2 to 8 wee

What does the cro-optimization skill do?
Run conversion rate optimization through hypothesis-driven testing including audit, hypothesis generation, test design, statistical analysis, and rollout decisions.

How do I install it?
Run `npx skills add rampstackco/claude-skills --skill cro-optimization --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From rampstackco/claude-skills, a repository with 515 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
