How were these skills chosen?
Each pick is listed in the directory, sits in the Marketing and SEO category or does SEO work, and is the strongest scorer for its job. The score is the directory's graded-v2 quality score. It adds points for passing the structural checks, a clear trigger description, a stated boundary, instruction depth, bundled references and scripts, recent commits, citations from curated lists, and declared tool permissions. Published scores run from 0 to 99.
The score measures structural evidence in the skill's files. It does not measure how well the skill ranks your pages. Read each SKILL.md before you install it, and check what it sends to outside services: seo-dataforseo and seo-google, for example, call external APIs with your credentials.
Which skill should you use for a technical SEO audit?
Use seo-audit from coreyhaines31/marketingskills when you want an agent to diagnose why a site is not ranking. It scored 88/100 and its repository is cited by four curated lists in the snapshot, the maximum adoption credit. If you also want the audit to report on AI search performance, seo from mblode/agent-skills (87/100) covers technical fixes, demand research, content briefs and SEO, AEO and GEO measurement in one skill.
For a whole-site crawl, AgriciDaniel/claude-seo splits the work into many focused skills. Its umbrella seo skill (81/100) covers full audits, single pages, technical checks, schema, images, sitemaps and AI search. It works as a hub: when you already know the job, use the narrower skill from the same repository.
Which skills help you show up in AI Overviews, ChatGPT and Perplexity?
Three listed skills target AI answers directly: ai-seo (coreyhaines31/marketingskills), seo-geo (infrasity-labs/dev-gtm-claude-skills) and seo-content (AgriciDaniel/claude-seo), which grades AI citation readiness. agent-ready from mblode/agent-skills (91/100) works on the machine side: llms.txt coverage and docs that agents can read without hitting 404s.
Keep Google's own guidance in view while you use them. Google Search Central says there are no additional requirements to appear in AI Overviews or AI Mode. A page needs to be indexed and eligible to show in Search with a snippet, and no special schema.org markup is required. Traffic from those features is counted in the Search Console Performance report under the Web search type. (Google Search Central: AI features and your website)
So the work that moves AI visibility is ordinary SEO done well, plus pages written so a model can lift a clean answer: a direct answer at the top, question headings, specific facts with sources, and a consistent name for your company and product everywhere it appears.
Which skills handle schema markup?
schema from coreyhaines31/marketingskills scored 90/100, the top schema skill in the directory. seo-schema from AgriciDaniel/claude-seo (81/100) detects, validates and generates Schema.org JSON-LD for a page or entity. Whichever you use, Google's rule holds: structured data has to match the visible text on the page.
Which skills cover keyword research and content briefs?
keyword-deep-dive from inhouseseo/superseo-skills (81/100) reads the top results and competitor pages for one keyword and returns a 90-day ranking plan. seo-content-brief from AgriciDaniel/claude-seo (86/100) turns competitor pages into a brief with section-level word counts. For live search volume, difficulty and SERP data, seo-dataforseo (88/100) connects to DataForSEO, which needs your own DataForSEO account.
What about local, international and programmatic SEO?
- Local:
seo-maps(85/100) covers geo-grid rank tracking, Google Business Profile audits and review analysis. - International:
seo-hreflang(86/100) audits and generates hreflang and catches the common mistakes. - Programmatic:
programmatic-seo(88/100) plans template-driven pages built from data. Pair it with an index-worthiness gate so thin pages never ship.
Can an SEO skill replace an SEO agency?
A skill gives your agent a repeatable method: it runs the checks, drafts the fixes and keeps the output consistent. What it does not bring is a strategy tied to your revenue, implementation across your real stack, and months of measurement in Search Console and in AI answers to see what moved.
That is the work Suede AI's AEO, GEO and SEO team does for clients. If you want the skills above running inside a strategy someone owns, talk to Suede AI.
Does Suede AI publish its own SEO skills?
Yes. Suede AI's own pack is listed separately from the third-party directory so it never competes for directory rankings:
- suede-seo-audit: a nine-lane audit covering access, intent, metadata, structure, supported schema, E-E-A-T, clusters and exact rewrite fixes.
- suede-ai-seo: optimization for AI answers in ChatGPT, Perplexity, Claude, Gemini and Google AI Overviews.
- suede-visibility-grader: a fast A to F grade for findability, first-screen clarity, CTA pull, proof and AI citation readiness.
- suede-programmatic-seo: data-backed page programs with index-worthiness gates and rollout checks.
How do you install one of these skills?
Every listing has copy-ready commands. The fastest route for most agents is the skills CLI, for example:

FAQ
What is an SEO skill for Claude Code?
