Marketing Skills Review: A Whole Marketing Team, Installed With One Command

Marketing is not one job. It is an SEO audit on Monday, landing page copy on Tuesday, a pricing page rethink on Wednesday, and a launch plan by Friday. Hiring for each is slow. Doing it all yourself is slower. And asking a general-purpose agent to do it gives you generic advice with no method behind it.

Marketing Skills is the fix: 52 skills in one repository, built by Corey Haines, covering nearly every job a marketing team does. The repo holds 59,264 GitHub stars, it is MIT licensed, and one command installs the whole pack into Claude Code, Codex, Cursor, or Windsurf. Each skill is a specialist. Together they behave like a team.

What is Marketing Skills?

Marketing Skills is a collection of markdown-based agent skills organized into seven groups: SEO and discovery, conversion optimization, copywriting, email, social, paid ads, and analytics and growth. There are ten SEO and content skills alone, including a technical SEO audit, AI search optimization for LLM citations, programmatic SEO, and schema markup.

Every skill reads a shared foundation file first: your product marketing context, which holds your product, your audience, and your positioning. That shared context is what keeps 52 specialists consistent. The copywriter, the SEO auditor, and the pricing analyst all start from the same understanding of what you sell and who buys it.

Key Features

1. SEO audits with a method, not a vibe

The seo-audit skill finds technical and on-page problems and explains why a page is not ranking. The ai-seo skill optimizes pages to be cited by AI answers, covering the GEO and AEO work that traditional SEO checklists miss. The audit skill treats fetched page text as untrusted data, so instructions hidden in a page cannot steer it.

2. Conversion optimization across the funnel

Separate skills cover the landing page, the signup flow, onboarding, forms, popups, and the paywall upgrade. Each one is a focused audit with concrete fixes, so you can work the funnel one stage at a time instead of redesigning everything at once.

3. Copywriting that starts from positioning

Copywriting, copy editing, and content strategy skills all read the shared product context before writing a word. The output is landing page copy, emails, and launch plans that sound like your product, because the skill knows what the product is and who it is for.

4. A shared product context every skill reads first

The product-marketing-context file is the quiet core of the pack. Write it once, and every skill builds on it. Change your positioning, update one file, and all 52 skills adjust. Without it, each skill would start from zero.

5. Install everything, or just the skills you need

One command installs all 52 skills. A flag installs only the ones you name, such as the copywriting, page CRO, SEO audit, and analytics skills. It also installs as a Claude Code plugin from the same repository, so teams can standardize on the pack.

How It Works

Install the whole pack with the skills CLI. The command below installs all 52 skills:

npx skills add coreyhaines31/marketingskills

To install only a few, name them: add the flag for specific skills such as seo-audit, copywriting, or page-cro. Add the Claude Code agent flag so the skills land in the folder Claude Code reads. Then write your product marketing context once, and ask the agent for the job you need: audit my SEO, rewrite this landing page, plan the launch, review the signup flow.

Who Should Use Marketing Skills?

Founders and solo developers doing their own marketing are the core audience. It also fits small marketing teams that want a consistent method across SEO, copy, and CRO, and technical marketers who already use Claude Code and want marketing expertise inside the same tool. If you never touch marketing, the pack is not for you.

Pricing

Marketing Skills is free and MIT licensed. All 52 skills cost nothing. There is no paid tier, no account, and no usage limit. The skills are markdown instructions, so they cost nothing to run beyond your normal agent usage.

Pros and Cons

Pros: 52 skills cover the whole marketing stack in one install; the shared product context keeps every skill consistent; the SEO audit skill has a real security property, treating fetched pages as untrusted; MIT licensed with 59,264 stars, the most-starred non-dev skill pack in the ecosystem.

Cons: 52 skills is a lot to take in, and the pack is only as good as the product context you write; some skills overlap in scope, so two skills can give different advice on the same page; the quality of the output still depends on the model and on your brief; the count has drifted between 48 and 52 across sources as the repo grows, so check the repo for the current list.

Final Verdict

Marketing Skills is the strongest non-developer entry in this batch, and the clearest proof that skills are not just for code. One command turns a coding agent into a marketing team with a shared understanding of your product. If you run a product and do your own marketing, install the pack before your next launch.
