Claude Marketing Skills: 14 Vetted Picks by Marketing Job

Pick Claude marketing skills by the job first, because a copy library and an SEO audit skill are judged on different things:

Marketing job	Skill type that fits	What a good one does
Copy and campaigns	A library of task skills that share one product-context file	Reads your positioning before it writes a line of copy
SEO and AI search	An audit skill that bundles its own scripts	Fetches and parses your pages instead of answering from memory
Brand and design	Design-direction skills, plus a brand skill holding your colors and fonts	Pushes landing pages and visuals away from template defaults
Documents and decks	File-format skills with a theme skill on top	Produces real .pptx, .docx and .xlsx files you can edit
Building your own	A skill-authoring skill that runs evals	Tests whether your skill triggers and whether it helps

Page one for this search mixes GitHub repos with vendor listicles, and my view is that stars and roundups show what is popular, while the facts to check before installing are who maintains a skill, what license it ships under and what it will run on your machine. Each of the 14 picks below, or its section intro, lists those facts plus the install command, the job it fits and one caveat, all checked on the pick’s own repo or docs page on 26 September 2026.

For pick 2 and Anthropic’s skills, the date is the last commit to that plugin or skill folder, and for pick 6 it skips a bot that commits a star-history chart update every day. ZIP upload is the help center’s route for a skill folder, but claude.ai rejects any SKILL.md whose frontmatter uses fields beyond name, description, license, compatibility, metadata and allowed-tools (Claude Code docs). On 26 September 2026, skills in picks 2 through 6 and pick 10 carried such fields, while Corey Haines’ library, Taste Skill and the anthropics/skills repo used only allowed ones.

What Are Claude Marketing Skills?

Claude marketing skills are SKILL.md instruction folders that teach Claude a marketing job such as copywriting, an SEO audit or a campaign plan. Claude keeps each skill’s name and description in context and loads the full instructions only when the skill is invoked, by you or by Claude when a task matches; bundled scripts are run, not loaded into context, per the Claude Code skills documentation.

The file anatomy and how to write one are covered in what a Claude skill is and how to build one. If you are still choosing a chat assistant rather than extending one, start with free AI tools for marketing instead.

Copy and Campaign Skills

This is where the big libraries sit. Pick one of them as your base rather than installing all four, because their skills overlap on copy, email and SEO.

1. Marketing Skills by Corey Haines

Corey Haines’ library holds 50 skills covering CRO, copywriting, cold email, SEO, AI SEO, paid ads, pricing, launches and sales enablement. Its README calls product-marketing the foundation: every other skill checks it first to understand your product, audience and positioning.

• Maintainer: Corey Haines, whose agency Conversion Factory is linked from the README. The README says disclosed Verified Partners fund the work and do not influence what the core skills recommend.
• Claude Code: npx skills add coreyhaines31/marketingskills --skill copywriting cro -a claude-code, or /plugin marketplace add coreyhaines31/marketingskills then /plugin install marketing-skills.
• Start with: product-marketing, then copywriting, copy-editing and cro.
• Caveat: version 2.0 renamed 17 skills and merged page-cro and form-cro into cro, so a v1 install leaves stale folders beside the new ones. The README includes the cleanup command.

2. Anthropic’s Marketing Plugin

Anthropic’s marketing plugin drafts blog posts, social posts, newsletters, landing pages and press releases, and it builds campaign briefs, brand reviews, competitive briefs, performance reports, SEO audits and email sequences. It is built primarily for Cowork and also works in Claude Code, with connectors listed for Slack, Canva, Figma, HubSpot, Amplitude, Notion, Ahrefs, Similarweb, Klaviyo and Supermetrics. Since 16 September 2026, Anthropic has been merging Cowork into the Claude app, starting with Pro and Max plans (Claude Cowork and chat are now one Claude).

• Claude Code: claude plugin marketplace add anthropics/knowledge-work-plugins then claude plugin install marketing@knowledge-work-plugins.
• Start with: configure your brand voice, style guide and personas in the plugin’s local settings first, so brand-review checks against your rules instead of a generic review.
• Caveat: the plugin README lists five skills and seven commands, but on 26 September 2026 the skills folder held eight folders: one per command plus content-creation, and none for the other four README skills. Read the folder, not the README.

3. claude-marketing by Rebecca Rae Barton

The claude-marketing README counts 56 skills, and each ships three files: SKILL.md for frameworks, REFERENCE.md for benchmarks and API schemas, and EXAMPLES.md for worked prompts. Six packs group them, including a Paid Media Pack for Google, Meta and Microsoft Ads and a DTC pack for Klaviyo, Shopify, GA4 and Looker Studio.

• Claude Code: git clone https://github.com/thatrebeccarae/claude-marketing.git, then copy one skill with cp -r claude-marketing/skills/google-ads ~/.claude/skills/.
• Fits: paid media and e-commerce marketers who run Google Ads, Meta Ads or Klaviyo accounts.
• Caveat: the last public commit was over four months before this check, and it reads “Sync from upstream”. Check the dates in any REFERENCE.md before trusting a benchmark or an API limit.

4. OpenClaudia Skills

The OpenClaudia README counts 78 skills, covering SEO, content, email, ads, analytics and growth, installed together with npx openclaudia install --all or one at a time.

• Claude Code: npx skills add OpenClaudia/openclaudia-skills --skill seo-audit.
• Claude app: six skills (ai-image-gen, brand-research, i18n, organize-skills, podcast-edit and stock-images) carry argument-hint or user_invocable in their frontmatter, which the upload rejects.
• Caveat: several API-powered skills need your own third-party keys or accounts, including a Semrush API key, a prepaid Glasser account and an Enception API key (paid, with a free tier) for AI-citation reports, and some act rather than draft. The README’s own example sends an email sequence through Resend and posts to Discord. Read each SKILL.md before you give it credentials.

SEO and AI Search Skills

Audit skills automate the technical-audit part of an AI SEO strategy, and a dedicated one earns its place when you run audits often. If you only need one now and then, pick 1 already carries seo-audit, ai-seo, schema and programmatic-seo, and pick 2 has an seo-audit skill too.

5. Claude SEO by Agrici Daniel

Claude SEO runs 26 sub-skills and 19 specialist agents across technical SEO, E-E-A-T, Schema.org markup, GEO, local, e-commerce and international SEO. /seo audit <url> runs a full site audit, and /seo content-brief <topic> writes a brief with target keywords, an outline and internal links.

• Maintainer: Agrici Daniel. The README describes the project as having a single maintainer.
• Claude Code: /plugin marketplace add AgriciDaniel/claude-seo, then /plugin install claude-seo@agricidaniel-claude-seo, then /seo setup.
• Caveat: /seo setup creates an isolated Python environment and installs Playwright Chromium before the first audit. Early-access features sit in a membership-only community mirror, while the public repo gets the MIT releases.

6. GEO-SEO Claude by Zubair Trabzada

GEO-SEO Claude puts AI search first. /geo audit runs a full GEO and SEO audit with parallel subagents, /geo citability scores content for AI citation readiness, /geo crawlers checks robots.txt for AI crawlers, and /geo report-pdf builds a PDF report with charts.

• Claude Code: git clone https://github.com/zubair-trabzada/geo-seo-claude.git, then cd geo-seo-claude and ./install.sh (Python 3.8 or later; on Windows, Git Bash and install-win.sh).
• Caveat: the headline one-command install pipes a remote script straight into bash. Use the manual clone route so you can read install.sh before it runs.

If the citation side is new to you, my guide to getting cited by ChatGPT, Perplexity and Gemini explains what these AI-search audits are scoring.

Brand and Design Skills for Landing Pages

Picks 7, 8 and 11 through 14 all come from Anthropic’s skills repo. In Claude Code, add it with /plugin marketplace add anthropics/skills and install example-skills@anthropic-agent-skills, which brings 12 skills, 7 of them outside this list. To add only the ones you want, run npx skills add anthropics/skills --skill brand-guidelines --skill frontend-design -a claude-code. In the Claude app, the help center lets Free, Pro, Max and Team users toggle example skills on under Customize > Skills, and Enterprise users once an owner enables skills.

7. brand-guidelines (Anthropic)

This skill applies a fixed palette and type system to anything Claude produces. Out of the box it holds Anthropic’s own brand: dark #141413, an orange accent #d97757, Poppins for headings and Lora for body text.

• Fits: anyone producing decks, one-pagers or social graphics in a house style.
• Caveat: it is a template. Fork it and swap in your colors, fonts and logo rules, or it will style your work in Anthropic’s colors. If your rules live only in a PDF, write brand guidelines a skill can read first.

8. frontend-design (Anthropic)

Its own description promises guidance on aesthetic direction, typography and choices that “don’t read as templated defaults”. It also sets a quality floor: responsive down to mobile, visible keyboard focus and reduced motion respected.

• Fits: marketers who ship their own landing pages and campaign microsites.
• Caveat: its SKILL.md says nothing about search indexing. Check separately how the finished page renders for Google, which is where a vibe-coded site can fail to rank.

9. Taste Skill by Leon Lin

Taste Skill pushes AI-built interfaces toward stronger layout, typography, motion and spacing. It also includes image-generation skills for web, mobile and brand-kit reference boards, which you run with ChatGPT Images or a similar generator and then hand to Claude Code to build from.

• Maintainer: Leon Lin, with sponsors listed in the README.
• Claude Code: npx skills add https://github.com/Leonxlnx/taste-skill --skill "design-taste-frontend".
• Caveat: install by the name: field in the frontmatter, not the folder name. The default design-taste-frontend is now v2, which the README labels experimental and a substantial rewrite; v1 stays available as design-taste-frontend-v1.

10. Emil Kowalski’s Skills

Emil Kowalski’s set covers animation and interface polish: emil-design-eng, review-animations, improve-animations, find-animation-opportunities, animation-vocabulary, apple-design and pick-ui-library, among others. The README says they draw on his years at companies like Vercel and Linear.

• Claude Code: npx skills@latest add emilkowalski/skills.
• Claude app: review-animations, pick-ui-library and prototype set disable-model-invocation in their frontmatter, which the upload rejects.
• Caveat: the set mixes web skills with native ones such as write-swift and animate-expo. Run in a terminal, the CLI asks which to install, so tick only the web ones; run from inside a Claude Code session or with -y, it installs all 13.

Document and Deck Skills

11. pptx, docx, xlsx and pdf (Anthropic)

These four are the skills behind Claude’s file creation. They create, read and edit PowerPoint decks (including .potx templates and speaker notes), Word documents with tracked changes, Excel files with formulas and charts, and PDFs you need to merge, split, fill or OCR.

• Claude Code: /plugin install document-skills@anthropic-agent-skills after adding the anthropics/skills marketplace.
• Claude app: built in. The help center says that with Code execution and file creation on, Claude uses the Excel, Word, PowerPoint and PDF skills automatically when a request needs them.
• Caveat: the proprietary license bars derivative works and redistribution, so you cannot fork the pptx skill into a company deck skill. Put your deck rules in a separate skill of your own.

12. theme-factory (Anthropic)

It offers 10 preset color and font themes, Ocean Depths and Arctic Frost among them, shown in a theme-showcase.pdf, and applies the chosen one to slides, docs, reports or HTML landing pages. It can also generate a new theme when none fit.

• Fits: pairing with pick 11 so a deck comes out styled instead of default.
• Caveat: the workflow shows the showcase and waits for you to pick, so it runs as an interactive step rather than a batch styler.

13. doc-coauthoring (Anthropic)

It guides you through a three-stage workflow for proposals, technical specs and decision docs: context gathering, refinement and structure, then reader testing. For a marketer that maps to launch briefs, positioning docs and campaign proposals.

• Caveat: its folder holds only SKILL.md, with no license file, and the repo README says only that “many” of its skills are Apache 2.0. Check Anthropic’s terms before you redistribute an edited copy.

Build Your Own Claude Marketing Skills

Libraries cover the generic jobs. Your positioning, ICP, voice rules and approval steps are the part no public repo can know, and that is where writing your own skill pays off.

14. skill-creator (Anthropic)

skill-creator builds new skills, edits existing ones and measures them. Per the Claude Code docs on running evals with skill-creator, it stores test prompts, runs each case in its own subagent, grades assertions, benchmarks with-skill against without-skill, runs a blind A/B between two versions, and proposes description edits so the skill triggers on the right requests.

• Claude Code: /plugin install skill-creator@claude-plugins-official, or through example-skills from anthropics/skills.
• Caveat: the benchmark records token count and duration next to pass rate, so budget usage before a full eval loop.

For a public example of a marketing skill worth building, Emily Kramer of MKT1 tells marketers to build a /marketing-strategy skill: one central file that collects the outputs of 7 strategy exercises, from ICP prioritization and positioning to revenue levers and big-bet campaigns. If you already use custom slash commands, my guide to Claude Code commands shows where those files live.

How to Install Claude Code Marketing Skills

1. Pick the scope. The Claude Code docs on where skills live list ~/.claude/skills/ for all your projects on one machine and .claude/skills/ for one repository, which you commit so your team gets it too. Personal skills do not load in Cowork or cloud sessions.
2. Install with the CLI, one skill at a time. The vercel-labs/skills CLI installs from any GitHub repo: npx skills add <owner/repo> --skill <name>, with -g for the personal folder. Naming each skill keeps the rest of a 50-skill library out of the skill listing, which costs context on every turn. Pass -a claude-code when you run it from inside a Claude Code session; Corey Haines’ README warns that the non-interactive mode may otherwise install only to .agents/skills/, which Claude Code does not read.
3. Or install a plugin: run /plugin marketplace add <owner/repo>, then /plugin install <plugin>@<marketplace>. Plugin skills run namespaced as /plugin-name:skill-name.
4. Or copy the folder: clone the repo and copy one skill folder into either skills directory.
5. In the Claude app, upload a ZIP. Turn on Code execution and file creation, go to Customize > Skills, click ”+”, then “Create skill” and “Upload a skill”. Remove any frontmatter field outside the six listed above before you zip the folder.
6. Keep them current: npx skills update updates everything the CLI installed, and npx skills update -p limits it to project skills.

How to Vet a Claude Skill Before You Install It

Check	Where to look	What should make you pause
License	LICENSE file, or the license: line in the frontmatter	No license in the skill’s folder, or proprietary terms
Maintainer	README author section and GitHub profile	A single maintainer, or early features held back for members
Last commit	Commit history for the skill’s own folder, skipping bot commits	Months without a human commit on a skill that cites API limits or benchmarks
What it runs	SKILL.md, the scripts/ folder and any allowed-tools line	Scripts that send, post or publish, or broad pre-approved tools
Install method	The README’s install section, plus the frontmatter if you will upload to the Claude app	A one-liner that pipes a remote script into bash, or fields the Claude app upload rejects
Context cost	/skill-doctor in Claude Code	Skills that cost context on every turn and rarely get used

Anthropic’s docs back the fourth and sixth checks. A skill’s allowed-tools field grants listed tools without per-use approval for the turn that invokes it, and the docs tell you to review the allowed-tools of skills checked into a repository before you run Claude Code there. The docs also say every skill in the listing adds to your context on every turn whether or not Claude uses it, and /skill-doctor (Claude Code v2.1.252 or later) shows what each skill costs and how often it gets used.

Which of These Skills Are in My Setup

I build this site with Claude Code, the same way I moved it off WordPress to Astro. Of the 14 picks, Taste Skill, seven of Emil Kowalski’s skills and skill-creator are installed in that setup; the marketing libraries in this guide are vetted from their repos and docs, not from my own installs.

Install the Skill for Your Biggest Job First

The Claude marketing skills worth installing are the ones whose maintainer, license and scripts you have read. Pick the job that takes most of your week and install the one skill for it by name. Then read its SKILL.md before the first run.
