AI agent skills for SEO and content

SEO skills are worth judging by how much they refuse to do. The good ones audit against things that are checkable — structured data validity, canonical correctness, whether a page answers the query it targets — and decline to promise rankings. Anything that outputs a keyword-density number or suggests generating pages at scale is selling you a penalty. Prefer skills that write for the reader and treat markup as bookkeeping.

Every skill listed here is a plain SKILL.md file in the format Anthropic documents for Agent Skills, read unchanged by Cursor, OpenAI Codex and 60+ agents. Each passes a safety review before it is publicly listed; the verdict and declared capabilities are on every skill's page.

Frequently asked questions

What is an agent skill for SEO and content?

SEO skills are worth judging by how much they refuse to do. The good ones audit against things that are checkable — structured data validity, canonical correctness, whether a page answers the query it targets — and decline to promise rankings. Anything that outputs a keyword-density number or suggests generating pages at scale is selling you a penalty. Prefer skills that write for the reader and treat markup as bookkeeping.

Can an SEO skill audit a live site?

Some can, if your agent can fetch pages — they crawl a handful of URLs and check markup, headings and metadata. Others work purely on content you paste in. Network access is declared on every skill's page, so you can tell which kind you are installing.

Which agents can use these SEO and content skills?

Any agent that reads SKILL.md files: Claude Code, Claude.ai, Cursor, OpenAI Codex, Windsurf, OpenCode and 60+ others. The format is not vendor-specific, so the same file works everywhere — each agent just keeps its skills in a different directory, listed at /agents.

Are these SEO and content skills free?

Yes. Searching, reading and installing skills on SkillMD is free and needs no account. Individual skills carry their own licence, shown on each skill's page.
