How we picked these skills
We started with every SEO skill in the SkillDirectory catalog and kept the ones that do one clear job. Then we ranked them on four things.
- Clear scope: the skill says what it does and when to use it.
- Upkeep: recent commits and a recent update date.
- License: MIT or Apache-2.0, so you can reuse it with attribution.
- Setup cost: how many accounts or tools it needs before it works.
We have not run every skill on this list. The ranking reflects each skill's published description, license and upkeep, not a benchmark.
The 10 best Claude SEO skills
1. SEO Audit
Best for: a first, full audit of a site.
SEO Audit checks a site for problems from technical to on-page issues and returns them in priority order. It also states what it cannot detect, such as schema markup added by JavaScript.
Why it ranks first: it is broad, honest about its limits and updated in August 2026.
Heads-up: confirm important findings in Search Console, because an agent cannot see everything.

2. SEO Google
Best for: SEO decisions based on Google's own data.
SEO Google brings Search Console, URL inspection, sitemaps, PageSpeed Insights, CrUX field data and GA4 organic traffic into Claude. A credential section explains what works with a simple API key and what needs full OAuth.
Why it made the list: first-party data beats estimates from third-party tools.
Heads-up: each Google property needs its own authorisation, and the Indexing API has eligibility rules.

3. Keyword Deep Dive
Best for: planning how to rank for one valuable keyword.
Claude searches Google, reads the top ten results and classifies search intent. It then studies the top three competitor pages and writes a 90-day ranking plan.
Why it made the list: it is active, with 6 commits in six months, and focused on one outcome.
Heads-up: rankings also depend on links and authority, so treat the 90-day plan as a hypothesis.

4. AI SEO
Best for: appearing in AI-generated answers.
AI SEO optimises content so AI answer engines can find and cite it. It first gathers your current AI visibility, content and goals, then explains how AI search works.
Why it made the list: it is the most active skill here, with 9 commits in six months.
Heads-up: AI search changes fast and nobody controls citations, so use it alongside normal SEO.

5. Technical SEO Audit
Best for: deep technical diagnosis before a relaunch or after a traffic drop.
It scopes the audit, fetches pages and works through checklist modules. These cover crawling and indexing, JavaScript rendering, Core Web Vitals, structured data, canonicals, redirects and AI crawler visibility.
Disclosure: we built this skill and it is the only paid one on the list, a one-time purchase.
Heads-up: it audits what the agent can fetch, so confirm key findings in Search Console.

6. SEO Keyword Cluster
Best for: planning topic clusters around a seed keyword.
It groups keywords by intent and builds a pillar-and-spokes structure. You also get suggested headings, a build order and an internal-linking map.
Why it made the list: the internal-linking map saves a step most cluster plans skip.
Heads-up: it uses SE Ranking data, so you need an account and a connection.
Details: MIT license · skill page · source repository
7. Content Brief
Best for: briefs a writer can start from immediately.
Claude searches the keyword, reads the top ten results and classifies intent. It then maps People Also Ask questions and the content gap, and outlines the structure.
Why it made the list: it is actively maintained, with 7 commits in six months.
Heads-up: a brief guides the writer but does not guarantee rankings, so add your own expertise.
Details: Apache-2.0 license · skill page · source repository
8. Schema
Best for: adding or fixing structured data.
Schema works in JSON-LD and follows Google's guidelines, with accuracy as its first rule.
Why it made the list: structured data is easy to get wrong, and a checklist helps.
Heads-up: markup must match visible page content, so validate it in Google's Rich Results Test.
Details: MIT license · skill page · source repository
9. Programmatic SEO
Best for: directory, comparison and location pages built from data.
It covers template design, unique value per page, proprietary data and clean URL structure.
Why it made the list: it focuses on the quality rules that decide whether scaled pages survive.
Heads-up: thin, templated pages can be treated as spam, so start with a small batch.
Details: MIT license · skill page · source repository
10. SEO Backlink Gap
Best for: finding realistic link-building targets.
It finds domains that link to several competitors but not to you. Each prospect comes with authority, anchor samples and an outreach angle.
Why it made the list: it turns competitor data into a ready outreach list.
Heads-up: link data is an estimate, and links should be earned on merit.
