SEO Skills for Claude
A complete library of 81 SEO and content Agent Skills for Claude and compatible AI agents. MIT licensed, free.
What is it? SEO Skills by Gaznil is an installable library of 81 Agent Skills covering technical SEO, on-page optimization, AI search (GEO/AEO/LLMO), ecommerce SEO, international SEO, backlinks, local SEO, measurement and blog content production. Every skill does exactly one job that no other skill in the set does.

npx skills add gaznilmuzammil12-prog/seo-skills-by-gaznil@ai-seoHow it was built
Most SEO skill collections are either one oversized skill or a large pile with overlapping coverage. This library was assembled by opening and reading every candidate, then removing anything that duplicated a job another skill already did. Three verification passes were run against the final set:
- Purpose de-duplication. No two skills solve the same problem. Skills that duplicated an existing purpose were excluded regardless of how popular they were.
- Name-collision checking. All 81 names were checked against each other and against widely-installed SEO packs, so nothing silently shadows anything already present.
- Dangling-reference tracing. Every internal see also reference was followed. Missing targets were either added as skills or documented in an alias table.
Three skills whose upstream licence could not be established were deliberately excluded rather than published without attribution.

Frequently asked questions
What are the best SEO skills for Claude?
This library covers the full SEO surface in 81 skills with no overlapping coverage. It spans technical SEO, on-page, AI search, ecommerce, international, off-page, local, measurement and content production. Because purposes do not overlap, exactly one skill should match any given task, which makes skill selection unambiguous for the agent.
How do I add SEO skills to Claude Code?
Run npx skills add gaznilmuzammil12-prog/seo-skills-by-gaznil. To install a single skill, append @ and the skill name. To install as a plugin, use /plugin marketplace add followed by /plugin install.
What is the difference between SEO and AI SEO (GEO)?
Traditional SEO gets a page ranked. AI SEO — also called GEO (generative engine optimization) or AEO (answer engine optimization) — gets content cited inside AI-generated answers. A page can be cited by an AI system while ranking on page two or three, because AI systems select sources on structure, extractability and authority rather than rank position alone. The ai-seo skill in this library covers that, including llms.txt, Open Knowledge Format and agent readiness.
Are these SEO skills free?
Yes. All 81 are MIT licensed and free to use, modify and redistribute.
Do these skills work outside Claude?
Yes. They use the Agent Skills format — a directory containing a SKILL.md with YAML frontmatter. Any agent runtime that reads that format can use them.
What does this library not cover?
Three areas, deliberately, because no good implementation exists anywhere in the Agent Skills ecosystem: log file analysis, site migration SEO, and penalty and manual action recovery. If you build one of these, it belongs in this space.
