Short answer: install Corey Haines’ free marketingskills first, add Anthropic’s Marketing plugin for campaign planning, claude-seo for search and claude-ads for paid media. The 15 picks below are ranked by the marketing job each one does, across content, SEO, ads, email, brand, CRO and AI search, with three paid packs priced from their live pages.
One thing to say up front: this is a research-based ranking, not a hands-on benchmark. We read the repos, checked star counts through the GitHub API on 2 November 2026, read each skill’s own description, and loaded the paid product pages to confirm prices. We did not run timed tests or measure campaign results. Where a claim comes from a vendor, we say so.
What are the best Claude Code skills for marketing?
The best Claude Code skills for marketing in 2026 are Corey Haines’ free marketingskills library for day-to-day execution, Anthropic’s official Marketing plugin for campaign planning and brand review, and claude-seo for search. Paid ads teams should add claude-ads. Paid packs such as the Inflectual bundle ($167) mainly buy breadth and convenience, not capabilities the free repos lack.
A Claude Code skill is a folder with a SKILL.md file, plus optional reference files and scripts. Claude reads the short description of every installed skill and loads the full instructions only when your request matches. That makes skills different from a saved prompt: they can carry checklists, scoring rubrics and helper scripts that run each time.
If the format is new to you, read what Claude Code skills are first. If you do not live in a terminal, Claude Code skills for non-developers covers setup in plain steps.
Skills, plugins and MCP servers in one table
| Layer | What it adds | Marketing example |
|---|---|---|
| Skill | A repeatable method and files | A landing page CRO checklist |
| Plugin | A bundle of skills, commands and connectors | Anthropic’s Marketing plugin |
| MCP server | Live data or actions from an outside tool | DataForSEO keyword volume |
| Prompt | A one-off instruction | ”Write five subject lines” |
Takeaway: skills give Claude a method. Data still has to come from somewhere, usually an MCP server or your own exports.
How we ranked these skills
We ranked on five criteria, weighted roughly in this order:
- Marketing coverage. How many real marketing jobs the skill handles well. A library that covers copy, CRO, email and SEO ranks above a single-purpose tool, unless the single tool is the best at its job.
- Inspectability. Can you read every file before it runs? Free GitHub repos win here. Paid packs where you cannot preview the files lose points.
- Maintenance. We pulled the last push date for each repo from the GitHub API. Every free repo in the top ten was pushed within the last six weeks.
- More than a prompt. Reference files, rubrics, scripts or data connections count. A paragraph of advice does not.
- Adoption. GitHub stars are a popularity signal. They are not a quality score, and we never ranked on stars alone.
What we did not do: run every skill on a live campaign and compare results. Any list that claims one skill “increased conversions 40%” should show the test. We have not seen one published for any skill on this list.
Why sponsored lists are a problem here
Several of the top-ranking roundups for this keyword are published by tool vendors (Composio, Ryze and a prospecting vendor among them) and rank their own product highly. That does not make them wrong. It does mean you should check whether the author sells the number one pick. This post has no affiliate links.

1. coreyhaines31/marketingskills: best overall
If you install one marketing skill library, make it this one. It is free, MIT-licensed, and the most-starred marketing-specific skill repo we found at 57,851 stars.
The repo’s own description: “Marketing skills for Claude Code and AI agents. CRO, copywriting, SEO, analytics, and growth engineering.” Listing the skills/ folder through the GitHub API returned more than 50 skill folders, including:
- Copy:
copywriting,copy-editing,emails,cold-email,ad-creative - Conversion:
cro,signup,onboarding,popups,paywalls,pricing,ab-testing - Search:
seo-audit,ai-seo,programmatic-seo,schema,site-architecture,link-building - Strategy:
marketing-plan,content-strategy,launch,competitors,customer-research,marketing-psychology - Measurement:
analytics,attribution,conversion-tracking
Why it ranks first
Coverage is the obvious reason. The less obvious one: the skills share a product-context pattern, so you describe your product once and later skills read from it. That cuts the “explain my business again” overhead that makes AI marketing tools tiring.
Where it falls short
Breadth means some skills are thinner than a dedicated tool. Its SEO audit is lighter than claude-seo. It does not ship data connections, so keyword or analytics skills work from what you paste or connect.
Best for: solo marketers, founders and small teams who want one install that covers most weekly tasks. Our guide to Claude Code skills for marketers walks through this library by task.
2. Anthropic’s Marketing plugin: best for campaign planning
Anthropic’s official Marketing plugin is the best free pick for planning work: campaign plans, competitive briefs and performance reports. It sits in anthropics/knowledge-work-plugins (34,360 stars, Apache-2.0), a repo Anthropic describes as plugins “primarily intended for knowledge workers to use in Claude Cowork”. It also installs in Claude Code.
It ships five skills (content creation, campaign planning, brand voice, competitive analysis, performance analytics) and commands including /campaign-plan, /competitive-brief, /performance-report, /brand-review, /draft-content, /seo-audit and /email-sequence.
The connector angle
The plugin lists connectors for tools such as HubSpot, Ahrefs, SimilarWeb, Klaviyo, Canva and Figma. The plugin is free. The data behind those connectors needs your existing paid account with each vendor. If you already pay for HubSpot, this is the cheapest way to get Claude reading your real numbers.
Where it falls short
It is shallower than Corey Haines’ library on execution tasks like CRO or page copy. It is a planning and review layer more than a production line.
Best for: in-house marketers and product marketers who write plans and reports every week. See Claude Code skills for product marketers for role-specific setups.
3. claude-seo: best for search marketers
claude-seo is the deepest free SEO suite for Claude Code. At 25,519 stars and pushed on 1 November 2026, it is both popular and actively maintained.
The repo describes “26 sub-skills + 19 sub-agents covering technical SEO, E-E-A-T, schema, GEO/AEO, agent readiness (Lighthouse Agentic Browsing, WebMCP, llms.txt), backlinks, local SEO, e-commerce, international SEO, Google APIs, and PDF/Excel reporting”, plus “9 optional extensions for live SEO data”.
Why marketers (not only SEOs) should care
Most marketing teams own a blog and a few landing pages. They do not have an SEO specialist. claude-seo gives them a structured audit with scored findings, which is a better starting point than asking Claude “is my site OK?” and getting a generic checklist.
Where it falls short
It is big. Running a full audit spawns many sub-agents, which uses more tokens than a single skill. Keyword volume still needs a data source such as DataForSEO.
Best for: content marketers who own organic traffic. The full SEO picture is in Claude Code skills for SEO and audits specifically in Claude Code skills for SEO audits.
4. claude-ads: best for paid media
claude-ads is the strongest free skill we found for paid media teams. Same author as claude-seo, 10,653 stars, pushed 1 November 2026.
Its description covers 12 ad platforms: “Google, Meta, YouTube, LinkedIn, TikTok, Microsoft, Apple, Amazon, Reddit, Pinterest, Snapchat, X”. It promises “source-grounded audits, deterministic findings and evidence coverage, versioned JSON reports, and capability-gated account changes”.
What “capability-gated” means for you
Read that phrase carefully. It means the skill separates reading your account from changing it, and only makes changes when the matching access is granted. For an ad account that spends real money, that boundary matters more than any feature.
Where it falls short
Audit quality depends on what data you give it. With pasted exports it can still score structure, budget allocation and creative variety. With no data, it can only explain best practice.
Best for: PPC managers and growth marketers running two or more ad platforms. More detail in Claude Code skills for PPC and Claude Code skills for ad copy.
5. Anthropic brand-voice plugin: best for brand consistency
The brand-voice plugin is the best free tool for turning scattered brand docs into rules Claude actually follows. It lives at partner-built/brand-voice inside anthropics/knowledge-work-plugins, was built by Tribe AI as a launch partner, and is free.
It has three commands:
| Command | What it does |
|---|---|
/brand-voice:discover-brand | Finds brand material across your connected docs |
/brand-voice:generate-guidelines | Turns that material into written guidelines |
/brand-voice:enforce-voice | Checks new drafts against those guidelines |
Why it ranks above more popular tools
Brand drift is the most common complaint marketers raise about AI drafts. A guideline file Claude reads on every draft fixes more of that than a better writing prompt. The plugin’s “We Are / We Are Not” format is useful even if you never install it.
Best for: teams with more than one writer, and agencies juggling client voices. Our Claude Code skills for brand voice guide compares it with build-your-own options.
6. humanizer: best for editing AI drafts
blader/humanizer is the most-starred editing skill on this list at 63,467 stars. Its description: “Agent skill that removes signs of AI-generated writing from text.”
It works from a list of recognisable AI writing patterns (inflated phrasing, rule-of-three lists, overused vocabulary, heavy dash use) and rewrites to remove them.
The honest limit
A humanizer makes text read less like a machine wrote it. It does not add facts, experience or a point of view. A thin draft that has been humanized is still thin. Use it as the last pass, after a human has added the real substance.
Best for: content writers and anyone publishing at volume. See Claude Code skills for humanizing AI writing and Claude Code skills for editing.
7 to 12: specialist skills worth adding
These six are narrower. Each is the best pick for one job.
7. geo-seo-claude: AI search visibility
zubair-trabzada/geo-seo-claude (11,404 stars) calls itself a “GEO-first SEO skill” with “citability scoring, AI crawler analysis, brand authority, schema markup, platform-specific optimization, and PDF reports”. Pick it if your boss asks why ChatGPT never mentions your brand. The repo README also promotes a paid community; the skill itself is MIT. More in Claude Code skills for GEO.
8. SEO Machine: blog production
TheCraigHewitt/seomachine (7,567 stars) is “a specialized Claude Code workspace for creating long-form, SEO-optimized blog content”. It is a workspace with commands, not a single skill. Good for teams publishing several posts a week. Pair it with content brief skills.
9. anthropics/skills: skill-creator and brand assets
Anthropic’s reference repo (186,355 stars) is not marketing-specific, but two parts matter to marketers. skill-creator helps you build your own skills from a description. The brand and design skills help produce on-brand documents and graphics. Read the repo before installing, since its licensing differs by folder (the API returned no single license).
10. alirezarezvani/claude-skills: a second broad library
About 29.1k stars and MIT-licensed. Its marketing section overlaps with Corey Haines’ library. Install it if a specific skill there fits a job the first library misses, not both wholesale. Two libraries with overlapping triggers can make Claude pick the wrong one.
11. DataForSEO MCP server: the data layer
Not a skill, but most SEO and content skills get better with it. dataforseo/mcp-server-typescript (258 stars) connects Claude to DataForSEO’s APIs. Pricing on dataforseo.com is pay-as-you-go with a $50 minimum top-up and a $1 trial credit. Low star count, high usefulness. Details in Claude Code skills for keyword research.
12. awesome-claude-skills: the directory
ComposioHQ/awesome-claude-skills (78,518 stars) is a curated list. Use it to find niche skills (LinkedIn posts, YouTube scripts, product descriptions) that no big library covers well. Composio maintains it and also sells its own tooling, so read its marketing entries with that in mind.
13 to 15: the paid marketing skill packs
Three paid packs came up repeatedly in our research. Prices below were checked on each live product page.
13. Inflectual Master Marketing Skills Bundle: $167 one-time
The Inflectual bundle sells 167 skills for $167, one-time, on Gumroad. It is the broadest paid pack we found. The pitch is coverage in one download, organised by marketing function.
Who it suits: marketers who would rather buy a ready set than assemble one from GitHub. Who it does not suit: anyone who wants to inspect every file before paying. We have not reviewed the full file set, so we cannot say how the quality of 167 skills compares with the free libraries above.
14. SuperSkills: $50
SuperSkills lists a $50 price on its page. It positions itself as a packaged skill set for marketing and content work. We did not purchase it, so we cannot describe the files beyond what the page shows.
15. Contra Ultimate Claude SEO & AEO Skills Pack: $39
The Contra pack lists $39, shown against $79. It is narrower: 12 SEO and AEO skill files, two Webflow bonus skills and a setup guide. If your site runs on Webflow, those bonus skills are the reason to consider it. Note that the $79 comparison is the seller’s own anchor, not a price we saw it sold at.
Are paid packs worth it?
Mostly, you pay for curation and time saved. Free repos at the top of this list are inspectable, maintained and broad. Paid packs make sense when your time costs more than the price and a seller has already organised skills by the job you do.
Free vs paid Claude Code marketing skills compared
| Factor | Free GitHub skills | Paid packs |
|---|---|---|
| Price | $0 for the skill | $39 to $167 in this list |
| Inspect before install | Yes, every file | Usually not before purchase |
| Update signal | Public commit history | Seller’s word |
| Breadth | Very wide with two or three repos | One-download breadth |
| Support | GitHub issues, community | Varies by seller |
| Data costs | Separate (APIs, tools) | Separate (APIs, tools) |
| Licence | MIT or Apache-2.0 mostly | Seller’s terms |
| Best for | Anyone comfortable reading a repo | Buyers who want a ready set |
Takeaway: for most marketers, the free stack is enough. Data is where the real spend goes, paid or free.
Best Claude Code skills by marketing role
The ranking above is general. Here is what we would install by job.
| Role | Install first | Add next | Read |
|---|---|---|---|
| Content marketer | marketingskills, humanizer | SEO Machine, claude-seo | content writers |
| SEO lead | claude-seo | DataForSEO MCP, geo-seo-claude | technical SEO |
| PPC manager | claude-ads | marketingskills ad-creative | PPC |
| Email marketer | marketingskills emails | Marketing plugin /email-sequence | email marketers |
| Growth marketer | marketingskills (CRO, A/B, analytics) | claude-ads | growth marketers |
| Brand or comms | brand-voice plugin | humanizer | brand voice |
| Social media manager | marketingskills social | awesome-claude-skills finds | social media managers |
| Agency | marketingskills, claude-seo, claude-ads | brand-voice per client | marketing agencies |
| Founder | marketingskills | Marketing plugin | founders |
Why role matters more than rank
A PPC manager gets more from the number four pick than the number one. Rank tells you general usefulness. Role tells you what to install today.
How to install Claude Code marketing skills
There are three common paths, depending on how the skill is packaged.
- Plain skill repos:
npx skills add coreyhaines31/marketingskillsinstalls from a GitHub repo through the skills CLI. - Plugins: in Claude Code, run
claude plugin marketplace add anthropics/knowledge-work-plugins, thenclaude plugin install marketing@knowledge-work-plugins. - Manual: copy the skill folder into
~/.claude/skills/for personal use, or.claude/skills/inside a project to share with a team.
Restart Claude Code, then ask for a task that matches the skill’s description. If it does not trigger, name the skill in your request.
A safety check before you install
Skills can include scripts that run on your machine. Read SKILL.md and anything in scripts/ before installing. This is the main reason free, inspectable repos ranked high. Full walkthrough: how to install Claude Code skills.
Common mistakes marketers make with Claude Code skills
In our reading, most of the problems people describe come from setup, not from the skills themselves.
- Installing everything. Five overlapping libraries means five skills claiming the same task. Claude picks one, and it may not be the one you wanted. Start with two or three.
- No product context. A copywriting skill without your audience, offer and proof writes generic copy. Fill in the product-context file first.
- Expecting data from nowhere. A keyword or ad audit skill without data will describe best practice, not your account.
- Trusting invented numbers. If Claude reports search volume and no data source is connected, the number is a guess. Ask where it came from.
- Skipping the human pass. Skills make drafts faster. They do not make claims true. Someone still checks facts, prices and promises before publishing.
- Ignoring updates. Marketing platforms change. A skill last updated a year ago may describe settings that no longer exist. Check the last push date.
Takeaway: fewer skills, more context, a real data source and a human check beat a larger install every time.
When to build your own marketing skill
Build your own when your process is specific: a client-reporting format, a house style, a launch checklist nobody else uses.
A minimal skill is one folder with a SKILL.md containing a name, a description of when to use it, and the steps. Add a references/ folder for your brand guide or examples. Anthropic’s skill-creator will draft the structure from a plain-language description.
Good first skills for marketers:
- A brand voice file with “We Are / We Are Not” pairs
- Your weekly report template, with the metrics you always pull
- A landing page review checklist built from your past winning pages
- A headline formula set tuned to your audience
The full process is in how to build a Claude Code skill. Headline-specific ideas are in Claude Code skills for headlines.
FAQ
What are the best Claude Code skills for marketing?
For most people: coreyhaines31/marketingskills for execution, Anthropic’s Marketing plugin for planning, and claude-seo for search. Paid ads teams should add claude-ads. All four are free.
Are Claude Code marketing skills free?
The strongest ones are. Every pick in our top 12 is free to install. Data sources and connected tools often cost money.
What is the best paid Claude marketing skills pack?
For breadth, the Inflectual bundle ($167 one-time, 167 skills). For a cheaper start, SuperSkills ($50). For SEO on Webflow, the Contra pack ($39). We have not tested any of them hands-on.
Is this ranking based on testing?
No. It is research-based: repo contents, GitHub API data, product pages and public descriptions. We did not run controlled tests on campaigns.
Does Anthropic make official marketing skills?
Yes. The Marketing plugin and the partner-built brand-voice plugin live in anthropics/knowledge-work-plugins, which is Apache-2.0 licensed.
Who built the brand-voice plugin?
Tribe AI, as a launch partner. It sits under partner-built/brand-voice in Anthropic’s repo and is free.
Can Claude Code skills run my ad accounts?
claude-ads can audit and, with the right access granted, make gated changes. Start read-only. Give change access only after you trust its findings.
Do I need to code to use marketing skills?
No. You need to run a terminal command or two to install. Using a skill is plain English. See our guide for non-developers.
How many skills should I install?
Start with two or three that cover your main jobs. Too many overlapping skills confuse which one triggers.
Do skills work in Claude.ai or only Claude Code?
Skills work across Claude Code, Claude.ai and the API, though install steps differ. Plugins from knowledge-work-plugins target Claude Cowork and Claude Code.
Can Claude do keyword research with skills?
Only well with data. Connect the DataForSEO MCP server or paste exports from your SEO tool. Without data, any volume is a guess.
How much does DataForSEO cost?
It is pay-as-you-go, with a $50 minimum top-up and a $1 trial credit, per dataforseo.com.
Are GitHub stars a good way to pick skills?
Partly. Stars show adoption, not quality. Check last push date and read the files.
Is it safe to install skills from GitHub?
Usually, if you read them first. Skills can contain scripts. Check scripts/ folders and avoid repos you cannot inspect.
What is the difference between a skill and a plugin?
A skill is one method folder. A plugin bundles skills, commands, agents and connector settings for one install.
Will a humanizer skill make AI content rank?
It removes AI tells. It does not add the experience, facts or original insight that search engines and readers reward.
Should agencies use paid packs?
Only if the pack covers jobs your free stack misses. Most agencies get further by building client-specific brand-voice skills on top of the free libraries.
