How many times have you typed the same SEO prompt into an AI tool this month? The same audit checklist. The same brief format. The same “don’t forget the meta description.”
Claude SEO skills turn that repeated prompt into a saved workflow Claude follows every time. Built well, they make SEO work faster and more consistent. Built badly, they mass-produce thin pages that Google is designed to ignore.
So which SEO jobs are skills good at, which are they bad at, and how do you build one that follows your rules? We run skills in our own content workflow, so this is the operator’s view, not a sales pitch.
What Is a Claude Skill?
A Claude skill is a folder of instructions, plus optional templates and scripts, that Claude loads when a task matches the skill’s description. For SEO, it turns a repeatable process such as an audit, a content brief or an on-page check into a saved workflow that Claude follows the same way every time.
The minimum is one file, SKILL.md, with a name and a short description at the top and the instructions below. Where you use it changes how you add and share it, according to Anthropic’s documentation and the Claude Help Center:
| Where | Who can use it | How skills are added | Sharing |
|---|---|---|---|
| Claude apps (web, desktop, mobile) | Pro, Max, Team and Enterprise, with code execution turned on | Upload the skill folder as a ZIP in Settings | Private to you; Team and Enterprise owners can provision skills for the whole organization |
| Claude Code | Anyone using Claude Code | A folder in ~/.claude/skills/ or in a project’s .claude/skills/ | Commit project skills to git, or package them as a plugin |
| Claude API | Developers | Upload through the Skills API | Shared across the workspace |
Custom skills do not sync between these. A skill uploaded to the Claude app is not available in Claude Code or the API. Anthropic also ships ready-made skills for Word, Excel, PowerPoint and PDF files.
How Does a Skill Work?
Skills beat a long pasted prompt because Claude only reads what it needs. Anthropic calls this progressive disclosure:
Level 1, always loaded: the name and description (about 100 tokens) → Level 2, when a task matches: the SKILL.md instructions → Level 3, only if needed: extra files such as a style guide, templates or scripts
That means you can install many skills without slowing every conversation down. It also means the description decides whether a skill fires at all. A vague description is the most common reason a skill sits unused.
In Claude Code, you can trigger a skill two ways: Claude loads it automatically when your request matches the description, or you type /skill-name to call it directly.
Five SEO Jobs Claude Skills Do Well
Each of these works because it is repeatable and rule-based. Each also depends on the data you give it.
1. Technical Audit Triage
Hand the skill a crawler export or Search Console data and it groups the issues, ranks them by impact and writes each fix in plain English for a developer. A crawl that arrives as twenty separate CSV files becomes one prioritized action list.
Needs: a crawl export (CSV) and Search Console data. Without them, it can only recite a generic checklist. Our technical SEO audit checklist shows what a full audit covers.
2. Content Briefs and Wireframes
A brief skill encodes your house structure: heading tags, word budgets per section, meta titles and descriptions with character counts, required internal links and FAQ format. Every brief comes out in the same shape, whoever asks for it.
Needs: competitor URLs or search results notes, plus your current site inventory. Verdict: one of the highest-value uses, because consistency is exactly what skills deliver.
3. On-Page and Style QA
This skill checks a draft against rules people forget under deadline: title length, focus keyword placement, banned phrases, link counts and word count. A skill can run a small script for checks a model would otherwise eyeball and get wrong.
Needs: your rules written down, plus the draft. Use our on-page SEO checklist as a starting point for those rules.
4. Internal Link Mapping
Given a list of live URLs and their topics, the skill suggests links and anchor text for a new post and flags orphan pages that nothing links to.
Needs: a current URL list from your sitemap or CMS. A skill that guesses slugs creates broken links, so never let it work from memory.
5. Search Console Opportunity Analysis
The skill finds pages ranking just off page one and queries with high impressions but a low click-through rate, then proposes title and content changes for each.
Needs: a Search Console connection or export. If you have not set one up, start with our Search Console setup guide.
Where Claude SEO Skills Fall Short
| Works well | Falls short |
|---|---|
| Repeatable processes with clear rules | Strategy, positioning and priorities |
| Structuring data you provide | Inventing data it does not have, such as rankings, volumes or competitor metrics |
| Consistent formats across many pieces | Original expertise, first-hand results and real client stories |
| Checklists and QA | Final judgment on what to publish |
A skill has no live data by default. Without a connected tool or an export, it has no rankings, search volumes or traffic figures. Treat any number it produces without a source as invented.
The bigger risk is autopublishing. Some workflows turn one keyword into a stack of articles and publish them automatically. Google’s scaled content abuse policy names exactly this: using generative AI to create many pages without adding value for users. Skills should speed up quality work, not multiply thin pages.
Size matters too. A bloated “do everything” skill performs worse than several small ones that each do a single job well. For the wider picture of AI and rankings, see how AI has changed SEO in 2026.
Anatomy of a Good SEO Skill
Here is the shape of a content brief skill, with what each file does:
seo-content-brief/
├── SKILL.md ← name, description, step-by-step instructions
├── house-style.md ← voice, banned phrases, formatting rules
├── templates/
│ └── blog-brief.md ← the exact output format
├── reference/
│ └── site-urls.md ← verified internal links only
└── scripts/
└── qa_check.py ← word count, title length, banned words
Five rules separate skills that work from skills that drift:
- Write the description as a trigger. Name the tasks and the words people actually use: “Use when asked for a blog brief, wireframe or content outline.”
- One job per skill. Chain small skills together instead of building one giant one.
- Specify the output format exactly with a template file, not a description of one.
- Give it a source of truth: verified stats, real URLs, published results. Tell it to leave a visible placeholder rather than guess.
- Put mechanical checks in a script. Counting characters is a job for code, not judgment.
Anthropic recommends keeping SKILL.md under about 500 lines and moving detail into supporting files, which Claude reads only when needed.
How We Use Skills in Our Content Workflow
Our content skill holds four things: our house style rules, a bank of verified numbers from our published case studies, templates for blogs and landing pages, and a QA script that checks word count and banned punctuation before anything reaches an editor.
The stat bank is the part that matters most. The skill may only cite client results that are already published, such as The Tooth Place (219 new patients in six months at $25.87 per lead) or Landmark Real Estate (452 leads at $19 each). If a number is missing, the draft shows a visible placeholder for a person to fill. It never invents one.
People still own the parts that decide whether content is any good: choosing the topic, verifying the research, adding first-hand insight, making the final edit and deciding whether to publish. Every piece goes out under a named author.
[FILL: optional before-and-after figure, such as time per brief; delete this line if keeping the section qualitative.]
The skill makes our standards repeatable. It does not replace the people who set them.
Are Third-Party Claude Skills Safe to Install?
Only if you trust the source and have read the files. Anthropic advises using skills you wrote yourself or ones from Anthropic.
A skill can instruct Claude to run code or call tools, so a malicious one could leak data or behave very differently from its description. Read every file before installing, including scripts, and be especially wary of skills that fetch content from external URLs.
Treat installing a skill like installing software on a work computer. And never put API keys or passwords inside a skill file.
How to Start: A 5-Step Plan
- Pick one task you repeat weekly, such as a content brief, an audit summary or a batch of meta descriptions.
- Write down how you do it today, including the rules you check by eye.
- Ask Claude to turn that process into a SKILL.md, then edit what it drafts.
- Test it on three real jobs and fix wherever the output drifts from what you would have done.
- Only then add the next skill. Share project skills with your team through git or your organization’s settings.
The Bottom Line
Claude’s SEO skills work when they encode a process you already know is good, run on real data, and leave the judgment to people. They fail when they replace data with guesses, or when they turn one keyword into a stack of thin pages. Start with one task, write your rules down, test against real work, and let the skill make your standards repeatable instead of making your content generic.

Frequently Asked Questions
No. Skills also work in the Claude apps on Pro, Max, Team and Enterprise plans with code execution turned on, and through the Claude API for developers.
No. A skill has no ranking or keyword database of its own. It works with the data you export from those tools or connect to Claude.
They overlap, but a skill is a folder that can include files and scripts, loads only when relevant, and can be used in Claude Code and the API as well as the app.
Yes, depending on where you use it. Commit project skills to git in Claude Code, or ask a Team or Enterprise owner to provision them in the Claude apps.
Only if it is useful. Google judges the page, not the tool, and mass-produced pages without added value break its spam policies.
Start with one. Add skills only for tasks you repeat often enough to justify maintaining them, since every skill needs updating as your process changes.
Tighten the description, add an output template and an example, and move any mechanical checks into a script so they stop depending on judgment.
