About ProSEO

A Claude Code plugin of 32 SEO skills, 18 sub-agents and 53 Python tools, covering technical SEO, content quality, schema, AI-search visibility, local, e-commerce and international SEO.

What it is

ProSEO is a set of skills for Claude Code. Each one encodes a specific SEO workflow — what to check, in what order, and how to judge the result — so the analysis is repeatable rather than improvised. Skills can be run individually as one-off checks, or through a staged lifecycle that keeps state between sessions.

It reads public pages and public APIs. Most skills need no credentials; the few that do (Search Console, GA4) store configuration in ~/.config/pro-seo/, never in the repository.

How this documentation is built

Every page on this site is generated from the repository by site/build.py. Skill pages are built by reading each skills/<name>/SKILL.md, the reference page by reading the agent and script files. The published docs therefore cannot drift from what is actually installed — if a skill is added and not documented, the build fails rather than shipping a site that quietly omits it.

The footer of every page states the commit it was built from, so you can always tell which version of the source you are reading.

How the content here is written

The usage notes and the "reading the result" guidance on each skill page are hand-written, not generated — the SKILL.md files are written as instructions to Claude and read oddly to a person. Anything describing what a skill produces is traceable to that skill's source file.

Deliberately absent: invented sample output. Where a skill emits a score, these pages say that it emits a score rather than showing a made-up one, because a number on a documentation page reads as real.

A worked example

This site was audited with pro-seo-audit. The first run scored it 69/100 and found five issues: undescriptive titles, thin pages, no structured data, no social preview image, and a 404 where the skills hub should have been. It also caught a contrast failure the build had shipped. Applying the recommendations moved it to 86/100. The audit artifacts are in the repository under proseo-docs-audit/.
