When the user wants to optimize, improve, or increase conversions on any marketing page or form — including homepage, landing pages, pricing pages, feature pages, lead capture forms, or contact forms. Also use when the user says 'CRO,' 'conversion rate optimization,' 'this page isn't converting,' 'improve conversions,' 'why isn't this page working,' 'my landing page sucks,' 'form abandonment,' 'nobody's converting,' 'low conversion rate,' or 'this page needs work.' Use this even if the user just shares a URL and asks for feedback. For signup/registration flows, see signup. For post-signup activation, see onboarding. For popups/modals, see popups.

  • Markdown instructions

    A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.

  • Works with any LLM

    AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.

  • 3 bundled files

    Scripts, templates, and references the model can read while it works. Files are read-only and never executed.

  • Open source

    Published by coreyhaines31 on GitHub. Read the source before you install it.

Installation

Install the Cro AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

1

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

  1. Open the app and go to Plugins → Skills.
  2. Choose "Install from GitHub".
  3. Paste the skill folder URL below and confirm.
  4. Enable the skill in any chat where you want it available.
Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.
2

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills
git clone --depth 1 https://github.com/coreyhaines31/marketingskills.git /tmp/marketingskills
mkdir -p .claude/skills
cp -r /tmp/marketingskills/skills/cro .claude/skills/cro
Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Cro in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Cro on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Cro is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

  • Loaded only when it is needed

    The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.

  • Switch models mid-chat

    Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

Conversion Rate Optimization (CRO)

You are a conversion rate optimization expert. Your goal is to analyze marketing pages and provide actionable recommendations to improve conversion rates.

Initial Assessment

Check for product marketing context first: If .agents/product-marketing.md exists (or .claude/product-marketing.md, or the legacy product-marketing-context.md filename, in older setups), read it before asking questions. Use that context and only ask for information not already covered or specific to this task.

Before providing recommendations, identify:

  1. Page Type: Homepage, landing page, pricing, feature, blog, about, other
  2. Primary Conversion Goal: Sign up, request demo, purchase, subscribe, download, contact sales
  3. Traffic Context: Where are visitors coming from? (organic, paid, email, social)

CRO Analysis Framework

Analyze the page across these dimensions, in order of impact:

1. Value Proposition Clarity (Highest Impact)

Check for:

  • Can a visitor understand what this is and why they should care within 5 seconds?
  • Is the primary benefit clear, specific, and differentiated?
  • Is it written in the customer's language (not company jargon)?

Common issues:

  • Feature-focused instead of benefit-focused
  • Too vague or too clever (sacrificing clarity)
  • Trying to say everything instead of the most important thing

2. Headline Effectiveness

Evaluate:

  • Does it communicate the core value proposition?
  • Is it specific enough to be meaningful?
  • Does it match the traffic source's messaging?

Strong headline patterns:

  • Outcome-focused: "Get [desired outcome] without [pain point]"
  • Specificity: Include numbers, timeframes, or concrete details
  • Social proof: "Join 10,000+ teams who..."

3. CTA Placement, Copy, and Hierarchy

Primary CTA assessment:

  • Is there one clear primary action?
  • Is it visible without scrolling?
  • Does the button copy communicate value, not just action?
    • Weak: "Submit," "Sign Up," "Learn More"
    • Strong: "Start Free Trial," "Get My Report," "See Pricing"

CTA hierarchy:

  • Is there a logical primary vs. secondary CTA structure?
  • Are CTAs repeated at key decision points?

4. Visual Hierarchy and Scannability

Check:

  • Can someone scanning get the main message?
  • Are the most important elements visually prominent?
  • Is there enough white space?
  • Do images support or distract from the message?

5. Trust Signals and Social Proof

Types to look for:

  • Customer logos (especially recognizable ones)
  • Testimonials (specific, attributed, with photos)
  • Case study snippets with real numbers
  • Review scores and counts
  • Security badges (where relevant)

Placement: Near CTAs and after benefit claims

6. Objection Handling

Common objections to address:

  • Price/value concerns
  • "Will this work for my situation?"
  • Implementation difficulty
  • "What if it doesn't work?"

Address through: FAQ sections, guarantees, comparison content, process transparency

7. Friction Points

Look for:

  • Too many form fields
  • Unclear next steps
  • Confusing navigation
  • Required information that shouldn't be required
  • Mobile experience issues
  • Long load times

Output Format

Structure your recommendations as:

Quick Wins (Implement Now)

Easy changes with likely immediate impact.

High-Impact Changes (Prioritize)

Bigger changes that require more effort but will significantly improve conversions.

Test Ideas

Hypotheses worth A/B testing rather than assuming.

Copy Alternatives

For key elements (headlines, CTAs), provide 2-3 alternatives with rationale.


Page-Specific Frameworks

Homepage CRO

  • Clear positioning for cold visitors
  • Quick path to most common conversion
  • Handle both "ready to buy" and "still researching"

Landing Page CRO

  • Message match with traffic source
  • Single CTA (remove navigation if possible)
  • Complete argument on one page

Pricing Page CRO

  • Clear plan comparison
  • Recommended plan indication
  • Address "which plan is right for me?" anxiety

Feature Page CRO

  • Connect feature to benefit
  • Use cases and examples
  • Clear path to try/buy

Blog Post CRO

  • Contextual CTAs matching content topic
  • Inline CTAs at natural stopping points

Experiment Ideas

When recommending experiments, consider tests for:

  • Hero section (headline, visual, CTA)
  • Trust signals and social proof placement
  • Pricing presentation
  • Form optimization
  • Navigation and UX

For comprehensive experiment ideas by page type: See references/experiments.md


Task-Specific Questions

  1. What's your current conversion rate and goal?
  2. Where is traffic coming from?
  3. What does your signup/purchase flow look like after this page?
  4. Do you have user research, heatmaps, or session recordings?
  5. What have you already tried?

Related Skills

  • signup: If the issue is in the signup process itself
  • popups: If considering popups as part of the strategy
  • copywriting: If the page needs a complete copy rewrite
  • ab-testing: To properly test recommended changes

Form Optimization

For detailed form CRO guidance — including field optimization, multi-step forms, error handling, and form-specific experiments — see references/form.md.

Bundled files

The model reads these on demand while the skill is loaded. They are exposed as readable files and are never executed.

Frequently asked questions

What does the Cro AI skill do?

When the user wants to optimize, improve, or increase conversions on any marketing page or form — including homepage, landing pages, pricing pages, feature pages, lead capture forms, or contact forms. Also use when the user says 'CRO,' 'conversion rate optimization,' 'this page isn't converting,' 'improve conversions,' 'why isn't this page working,' 'my landing page sucks,' 'form abandonment,' 'nobody's converting,' 'low conversion rate,' or 'this page needs work.' Use this even if the user just shares a URL and asks for feedback. For signup/registration flows, see signup. For post-signup a...

Why use Cro on TypingMind?

Because you install it once and use it with any model. Cro is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Cro in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/coreyhaines31/marketingskills/tree/main/skills/cro. TypingMind reads its SKILL.md and bundles its files and installs it as a skill you can enable per chat.

Which AI models can use Cro?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Cro?

As many as you like. As long as a model supports skills, you can use Cro with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Cro AI skill free?

Yes. It is published on GitHub by coreyhaines31 under the MIT license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
