Marketing Skills for Claude Code: 40+ Free Skills Reviewed

You don't need to know marketing to use a marketing skill. If you're building a product and need landing page copy that converts, an SEO-friendly blog post, or a lead magnet that doesn't sound like a robot wrote it — someone already solved that problem and packaged it as marketing skills for Claude Code.

Marketing Skills is a free collection of Claude Code skills that covers the entire marketing funnel. Install it once and Claude gains deep, structured expertise across SEO, copywriting, email, ads, CRO, and growth engineering. You don't have to prompt-engineer your way through any of it.

What Is Marketing Skills?

Who built it and why

Marketing Skills is an open-source project maintained on GitHub at github.com/coreyhaines31/marketingskills. It was built to give Claude Code the kind of opinionated, domain-specific marketing knowledge that generic prompting can't reliably produce.

Instead of asking Claude "write me a good headline" and getting something generic, you install the skill and Claude reasons through your headline using direct response principles, audience psychology, and copywriting frameworks — because that's what the skill teaches it to do.

What "40+ skills" actually means

The collection contains 40+ individual skills, each living in its own folder with its own SKILL.md file. When you install the full collection, Claude gains access to all of them. Each skill has a description that tells Claude when to activate it automatically — so if you're asking about conversion rates, the CRO skill kicks in; if you're writing a subject line, the email skill takes over.

This is different from a single monolithic prompt. You get 40+ specialists, not one generalist with a marketing hat on.

If you're new to how skills work in general, the Claude Code Skills explainer covers the mechanics — including where files go and how Claude decides when to use them.

What's Inside: The Full Skill List

SEO skills

The SEO skills cover the parts of search optimization that require actual judgment, not just keyword stuffing. Expect skills for:

• Keyword research and clustering
• On-page optimization (title tags, meta descriptions, heading structure)
• Content briefs — structured outlines built around search intent
• Internal linking strategy
• Technical SEO audit checklists

These are useful even if you're not a content site. If you're building a product and want your landing page to rank for anything, the on-page optimization skill alone is worth the install.

Copywriting and direct response

This is the strongest section of the collection. The copywriting skills give Claude a framework for writing copy that sells rather than copy that describes.

Skills in this section include:

• Landing page copy (headline, subhead, benefits, CTA)
• Value proposition development
• Feature-to-benefit translation
• Headline formulas (curiosity, specificity, urgency)
• Long-form sales page structure

The direct response skills are particularly useful for indie developers who aren't marketers but need their product pages to do actual work. You describe your product, the skill handles the persuasion architecture.

Email and lead generation

Email is one of the harder formats to get right — short, personal, and it needs to earn the next click. The email skills include:

• Cold outreach sequences
• Welcome email flows
• Subject line generation (with A/B variants)
• Lead magnet concept and outline generation

The lead magnet skill is a standout. You describe your audience and your product, and Claude produces a structured concept for a downloadable asset that would attract your ideal customers — not a vague "create a checklist" suggestion, but a specific brief with title, format, and contents.

Ads and CRO

The ads skills cover paid channels — primarily Google Ads and Meta — with skills for:

• Ad copy variations (headlines, descriptions, CTAs)
• Audience targeting recommendations
• Hook writing for short-form video scripts

The CRO (conversion rate optimization) skills focus on analyzing and improving existing pages. They work best when you paste in your current copy and ask Claude to run an audit — the skill gives it a structured rubric to evaluate against rather than just vibing.

Analytics and growth engineering

The growth engineering skills are the most technical part of the collection. They include analytics-tracking, ab-test-setup, and revops — covering UTM parameter strategy, funnel analysis framing, A/B test setup, and revenue operations.

These are less useful if you're just starting out. File them under "come back to this when you have traffic."

How to Install It

One-command install vs manual

The quickest path is a single command:

npx skills add coreyhaines31/marketingskills

That pulls the full collection into your Claude Code skills directory in one step. You can also install individual skills if you only want a subset:

npx skills add coreyhaines31/marketingskills --skill page-cro copywriting

Or if you prefer the manual path:

git clone https://github.com/coreyhaines31/marketingskills

Then copy the skills folder into your Claude Code setup.

Where the files land

Skills can live in two places depending on how you want to use them:

# Available only in the current project
your-project/.claude/skills/marketing-skills/

# Available across all your projects
~/.claude/skills/marketing-skills/

For a collection like this, the global location makes more sense. Marketing copy isn't project-specific — you'll want access to these skills wherever you're building.

Confirming it's working

Open Claude Code in any project and ask something like:

Write me a landing page headline for a task management app for freelancers.

If the skill is active, Claude's response will be structured around copywriting principles — not just a plain sentence. You'll notice it reasoning about audience, pain points, and specificity rather than giving you a one-liner and calling it done.

What It's Like to Use (Walkthrough)

Example: generating a landing page with the copywriting skill

Say you've built a browser extension that blocks distracting tabs during focus sessions. You don't have marketing copy yet.

With Marketing Skills installed, you can say:

I built a Chrome extension called FocusLock that blocks distracting sites during Pomodoro sessions.
Help me write a landing page: headline, subheadline, three benefit bullets, and a CTA button label.

The copywriting skill kicks in automatically. Instead of getting generic output, Claude applies a structure: the headline addresses the core pain (distraction), the subheadline introduces the mechanism (blocking, not willpower), the benefits translate features into outcomes, and the CTA is action-oriented and specific.

You'd get something ready to drop into your page — not a draft to rewrite from scratch.

Example: running an SEO audit with the SEO skill

Paste your existing page copy into Claude and say:

Audit this landing page copy for SEO. I'm targeting the keyword "focus timer for developers."

The SEO skill gives Claude a framework to check: Is the primary keyword in the H1? Are subheadings using semantic variants? Is the meta description within character limits and does it include the keyword? Does the page answer the search intent, or does it just use the words?

You get a structured list of what's missing — not a vague "optimize your content" suggestion.

Who Should Install This?

You're a good fit if:

• You're building a product and need marketing copy but aren't a marketer
• You're doing content SEO and want Claude to produce briefs and outlines with real structure
• You run paid ads and need fast copy variations to test
• You're writing email sequences and want them to follow a proven framework rather than vibes

You probably don't need this if you're only writing code and have no marketing surface to work on yet. But once you have a landing page, a waitlist, or any user-facing copy — it's worth the five-minute install.

The collection officially supports Claude Code, OpenAI Codex, Cursor, Windsurf, and any agent that implements the Agent Skills spec — but the primary use case and documentation is built around Claude Code.

The Bottom Line on Marketing Skills for Claude Code

Marketing Skills is one of the more immediately useful things in the Claude Code skill ecosystem, specifically because the payoff is visible. You ask for landing page copy, you get landing page copy that's been reasoned through a direct response framework. You ask for an SEO brief, you get a brief with structure.

It's free, it's open source, and the install is a few minutes. If you have any user-facing copy to write — even just a README or a product description — install it before you start.
