There is no official Claude skill called "marketing" or "SEO," so the best Claude skills for marketing in 2026 are the official ones that already do marketing jobs, plus a custom skill you build for your own workflow. Anthropic ships 17 skills; roughly six of them cover content, comms, decks, and brand visuals. Everything below is drawn from each skill's published SKILL.md, not a test bench.
If you need the basics first, a Claude Skill is a folder with a SKILL.md file that teaches Claude a repeatable procedure, loaded only when a task calls for it. That "loaded only when needed" property is what makes a marketing skill worth building: you write your process once, and Claude applies it the same way every time.
Is there an official Claude skill for marketing or SEO?
No. As of July 2026 the anthropics/skills repository publishes 17 skills, and none carries a "marketing" or "SEO" label. This matters, because most "best Claude marketing skills" lists imply Anthropic ships a keyword tool or an ad-account auditor. It doesn't. What it ships is a set of general skills, several of which happen to map cleanly onto marketing work. The honest answer for a marketer has three parts: use the official skills that fit, build your own for the SEO-specific jobs, and vet any third-party pack before you run it.
Which official skills actually do marketing work?
Six of the 17 pull their weight for a marketing or content team. Descriptions here come from each skill's SKILL.md frontmatter, as of July 2026.
| Skill | Marketing job | What the docs say it does |
|---|---|---|
internal-comms | Newsletters, FAQs, updates | Writes internal comms in set formats: newsletters, FAQs, status reports, leadership and project updates |
doc-coauthoring | Content briefs, proposals | Structured workflow to co-author docs: gather context, refine sections, test with a fresh reader |
canvas-design | Social graphics, one-pagers | Produces static visual art as .png and .pdf from a stated design philosophy |
brand-guidelines | On-brand artifacts | Applies Anthropic's official colors and typography to any artifact |
pptx | Decks, pitch decks | Create and edit PowerPoint presentations |
xlsx | Reporting, dashboards | Build spreadsheets with formulas, analysis, and charts |
Two honest caveats. The brand-guidelines skill applies Anthropic's brand, not yours, so treat it as a template to fork rather than a drop-in. And internal-comms is built for internal formats; external campaign copy needs your own guidance layered on top. Also useful, if a little further out: web-artifacts-builder builds React and Tailwind pages you can use as interactive one-pagers, and slack-gif-creator makes Slack-sized GIFs for launches.
The real answer: build your own SEO skill
For anything genuinely SEO-shaped, keyword clustering, internal-link audits, schema generation, SEO content briefs, the official repo has nothing purpose-built. That's the gap skill-creator fills. Per its documentation, it drafts a skill, runs test cases with and without it, writes assertions, and tunes the description so the skill triggers at the right moment.
This is where a marketing skill earns its keep. Encode your editorial rules, your internal-linking conventions, your title and schema requirements once, and Claude applies them the same way on every article instead of you re-explaining them per draft. It's the same discipline behind programmatic SEO: write the procedure down, reuse it at scale. If your goal is AI visibility rather than blue links, point the skill at the tactics in our LLM SEO guide. And if you'd rather not write YAML, you can record a Claude skill by walking through the task once.
What about ready-made SEO skill packs?
The community moved fast here, and some packs are genuinely substantial. Two examples, described strictly from their READMEs:
- SE Ranking's seo-skills publishes 26 skills powered by SE Ranking's remote MCP server, covering content briefs, keyword clustering, backlink gaps, schema, and AI-search share of voice. It's MIT-licensed but needs an SE Ranking account with API access to pull data.
- The community claudeskill pack advertises 25 sub-skills and 18 sub-agents across technical SEO, E-E-A-T, schema, and local SEO, MIT-licensed, with optional DataForSEO and Firecrawl extensions for live SERP and crawl data.
Neither claim is something we tested; both are what the maintainers document. That distinction is the whole game with third-party skills. A skill can tell Claude to run code and use tools, so an untrusted one is a supply-chain risk. Anthropic's guidance is blunt: treat installing a skill like installing software. Read every file in the bundle, watch anything that fetches external URLs, and prefer packs you can fully audit. A "best marketing skills" list that skips this step is selling you risk.
Where should a marketer start?
Pick by the job in front of you. Writing and reporting: the document skills plus internal-comms and doc-coauthoring cover most of it, and they ship on paid Claude.ai plans with no setup. Repeatable SEO production: build one skill with skill-creator before you install anything. Data-heavy audits: try a community pack, but read it first and expect to wire up an MCP server or API keys. For the broader toolkit around all of this, the general best Claude skills roundup covers every official skill, and our best AI SEO tools comparison covers the paid platforms these skills often plug into.
