Cro Methodology is an agent skill from wondelai/skills. Audit websites and landing pages for conversion issues and design evidence-based A/B tests. Use when the user mentions "landing page isnt converting", "conversion rate", "A/B test", "why visitors leave", "objection handling", "bounce rate", "conversion funnel", "increase signups", or "people add to cart but dont buy". Also trigger when diagnosing why signups are low, designing experiment hypotheses, or auditing checkout flows for friction points. Covers funnel mapping, persuasion assets, and…
Its SKILL.md is about 4.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 7 other files, including reference files (for example `references/COPYWRITING.md`, `references/OBJECTIONS.md` and `references/PERSUASION.md`).
It sits in Marketing & SEO, covering Conversion rate optimization, Landing pages and A/B testing. The repository describes itself as: Wondel.ai Agent Skills — Business, Marketing, UX & Coding Frameworks from Bestselling Books. 50 skills + 12 guided journeys for Claude Code, Codex, Cursor & other agentskills.io… The licence is MIT.

Cro Methodology loads about 4.3k tokens when it runs, and up to ~14k if it reads all its reference files. Until then it costs about 162 tokens; SKILL.md has 2,110 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Extraordinary improvements come from understanding WHY visitors don't convert, not from copying competitors or applying generic tips.
Don't guess -- discover. Every visitor who doesn't convert has a reason. Discover those reasons through research, then systematically eliminate them with evidence and proof. This evidence-based approach consistently outperforms "best practices", intuition, competitor copying, and expert opinion.
Goal: 10/10. Score any landing page, funnel, or conversion flow against the seven Quick Diagnostic rows below: award ~1.4 points per row answered "yes" (7 rows = 9.8, capped at 10). Bands: 9-10 = single clear action, research-grounded O/CO table, value prop legible in 5 seconds, proof at every friction point, funnel mapped, path free of UX blockers; 5-6 = guessed objections, generic best-practices copy, proof buried in FAQs; <=3 = competing CTAs, no funnel map, claims with no proof. Report the current score and the specific diagnostic rows failing.
Core concept: A systematic 9-step process moving from defining success metrics through research and experimentation to scaling wins across the business.
Why it works: Random optimization skips research. The process forces you to understand visitors before changing anything, so every change rests on evidence, not opinion.
Key insights:
Product applications:
| Context | CRO Process Step | Example |
|---|---|---|
| Landing page audit | Define goals, map funnel, research visitors | 70% bounce because value prop is unclear |
| Checkout optimization | Map funnel for blocked arteries | Shipping cost shock causes 40% cart abandonment |
| Email sequence | Scale wins | Winning objection-handling copy reused in drip emails |
Copy patterns:
See funnel-analysis.md when mapping the funnel -- step-by-step mapping, blocked-artery/missing-link diagnosis, industry funnel benchmarks, and impact-based prioritization.
Core concept: Visitors fail to convert for specific, discoverable reasons. Exit surveys, chat logs, support tickets, sales calls, and reviews reveal the "voice of the customer" and their real objections.
Why it works: Teams' guesses about why visitors leave are almost always wrong. Research uncovers objections no one anticipated, and the customer's own language out-persuades any copywriter's invention.
Key insights:
Product applications:
| Context | Research Method | Example |
|---|---|---|
| Exit intent | On-site survey | "What's preventing you from signing up today?" |
| Post-purchase | Email survey within 7 days | "What almost stopped you from buying?" |
| Objection mining | Support tickets + reviews | Search "but", "however", "worried about"; negative reviews = unaddressed objections |
Copy patterns:
Ethical boundary: Anonymize data, get consent for recordings, and don't survey so aggressively that you degrade the experience.
See RESEARCH.md when planning research -- ready-to-use survey questions per channel, recommended tools, and how to turn raw responses into a ranked objection list.
Core concept: Every company sits on overlooked proof -- undisplayed testimonials, unmentioned awards, hidden credentials, buried guarantees. Inventory these "persuasion assets", acquire missing ones, display them.
Why it works: Visitors decide on evidence, not claims. A modest claim with overwhelming proof beats a bold claim with none.
Key insights:
Product applications:
| Context | Persuasion Asset | Example |
|---|---|---|
| Landing page header | Logo bar + rating | "Trusted by 10,000+ companies" with 5 recognizable logos |
| Pricing page | Risk reversal | "30-day money-back guarantee, no questions asked" |
| Checkout flow | Trust badges near forms | Security certification, payment logos, guarantee seal |
Copy patterns:
Ethical boundary: Never fabricate testimonials, inflate statistics, or display fake trust badges -- all proof must be genuine and verifiable.
See PERSUASION.md when auditing or acquiring proof -- the full five-category asset checklist and psychological triggers. See COPYWRITING.md when writing the proof copy itself -- headline formulas, benefit-led phrasing, and proof-element wording.
Core concept: The Objection/Counter-Objection table is the core CRE technique: map every visitor objection to a specific, evidence-backed counter-objection.
Why it works: The table forces every counter to be placed where its objection arises in the reading flow, so a concern is answered the instant the visitor feels it -- not pages later, by which point they have already left.
Key insights:
Product applications:
| Objection | Visitor Question | Counter-Objections |
|---|---|---|
| Trust | "Why should I believe you?" | Named testimonials, media logos, awards, guarantee |
| Price | "Is it worth the money?" | ROI calculator, cost comparison vs. alternatives, payment plans |
| Fit | "Will it work for MY situation?" | Similar-customer case studies, segmented pages, free trial |
| Timing | "Why act now?" | Cost-of-delay math, genuine limited offers, seasonal relevance |
| Effort | "How hard will this be?" | "Done for you" framing, "Set up in 5 minutes", step-by-step breakdown |
Copy patterns:
Ethical boundary: A counter-objection must resolve the concern with real evidence, not dismiss a legitimate worry as unfounded.
See OBJECTIONS.md when building the O/CO table -- per-category counter-objection technique catalogs, CO-Only patterns for implicit objections, and how to mine objections from support logs.
Core concept: Every experiment needs a documented hypothesis linking a specific change to an expected outcome for a research-grounded reason, prioritized with ICE scoring (Impact, Confidence, Ease).
Why it works: A hypothesis forces you to articulate WHY a change should work, grounding it in customer research. ICE scoring stops teams wasting traffic on low-impact tweaks.
Key insights:
Worked example: "Customer language from surveys will lift signups because visitors see their own words" scores I:8, C:9, E:10 = 9.0 -- a top-priority test. A button-color swap scores ~I:2, C:2, E:10 = 4.7 and gets skipped despite being trivial to build.
Copy patterns:
See testing-methodology.md when prioritizing or scoring a backlog -- per-axis ICE scoring rubrics, a worked prioritization table, and the weighted-ICE variant.
Core concept: Run controlled experiments comparing page versions with proper statistical rigor, so results reflect reality rather than random noise.
Why it works: Without rigor you can't distinguish real improvements from random variation -- peeking, undersized samples, and ignored practical significance all manufacture false winners.
Key insights:
Product applications:
| Context | Test Type | Example |
|---|---|---|
| Concept validation | A/B test (2-4 variants) | Two fundamentally different layouts based on different customer insights |
| Low traffic | Bold A/B test | Dramatic changes reach significance on far smaller samples than timid ones |
| Post-test | Scale wins | Apply winning insights to landing pages, ad copy, email sequences |
Copy patterns:
Reporting rule: Decide sample size and duration up front, then report whatever the pre-set test returns -- never stop early on a peeked "winner," rerun a test until it yields the answer you want, or bury an inconclusive result. (This is the one honest-reporting constraint for the whole methodology.)
| Mistake | Why It Fails | Fix |
|---|---|---|
| Copying competitors blindly | You don't know if it even works for them | Research YOUR visitors' objections, build YOUR evidence |
| Testing button colors before understanding objections | Surface symptoms, tiny effects, wasted sample | Customer research first, then test big changes |
| Assuming you know why visitors leave | Teams are almost always wrong about motivations | Exit surveys, chat logs, support-ticket analysis |
| Applying "best practices" unvalidated | May not fit your audience, product, or context | Treat them as hypotheses to test, not rules |
| HiPPO decisions | Highest Paid Person's Opinion is not data | Let research and test results decide, not seniority |
| Optimizing pages without funnel context | Fixes shift problems elsewhere; misses biggest wins | Map the funnel, find blocked arteries, prioritize by impact |
| Meek tweaks instead of bold changes | Rarely reach significance; waste time and traffic | Test changes that could double conversion, not nudge it 2% |
| Giving up after one failed test | The opportunity still exists | Investigate why, return to research, try a bolder change |
Audit any landing page or conversion flow:
| Question | If No | Action |
|---|---|---|
| Do we know the ONE action visitors should take? | Page lacks focus | Define a single conversion goal; remove competing CTAs |
| Have we researched (not guessed) why visitors don't convert? | Optimization built on assumptions | Run exit surveys, analyze chat logs and tickets |
| Do we have an O/CO table? | Objections go unanswered | Build it from research; place counters at friction points |
| Is the value proposition clear within 5 seconds? | Visitors bounce before understanding | Run a 5-second test; rewrite headline in customer language |
| Are persuasion assets visible (testimonials, awards, guarantees)? | Claims without proof aren't believed | Audit assets, acquire missing ones, display prominently |
| Have we mapped the funnel for blocked arteries? | Optimizing the wrong page | Map traffic per stage, compare to benchmarks, prioritize |
| Is the path free of UX blockers (speed, mobile, form length)? | Friction kills converts who already decided to act | Fix load time, mobile layout, and over-long forms first |

Cro Methodology fits situations like: the user mentions landing page isnt converting; conversion rate; why visitors leave; objection handling.
Run `npx skills add wondelai/skills --skill cro-methodology -a claude-code`. Or copy the skill folder (cro-methodology in wondelai/skills) into .claude/skills/cro-methodology in your project. Claude Code loads it when a task matches its description.
Run `npx skills add wondelai/skills --skill cro-methodology -a codex`. Or copy the skill folder (cro-methodology in wondelai/skills) into .agents/skills/cro-methodology in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add wondelai/skills --skill cro-methodology -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/cro-methodology, .gemini/skills/cro-methodology, .github/skills/cro-methodology and .opencode/skills/cro-methodology in your project.
SKILL.md names no scripts, command-line tools or credentials: Cro Methodology is instructions for the agent only.
SKILL.md names 1 domain. As links in the text: amazon.com. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Cro Methodology is published under the MIT licence (declared in SKILL.md). It allows redistribution, so the full SKILL.md is shown on this page.
About 4.3k tokens (SKILL.md is roughly 17k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 9.7k tokens, read only when the agent opens those files.
