What on-page-seo-auditor does

The skill provides step-by-step guidance for inspecting on-page search engine optimization elements. The agent references rules in SKILL.md to analyze headers, meta tags, and copy structure directly within your coding workspace.

Development has shifted from the standalone seo-geo-claude-skills repo to the aaron-marketing-skills bundle. Installing from this signpost repository pulls the frozen standalone release tagged v9.9.12 at optimize/on-page-seo-auditor/SKILL.md. This is a reason to pull from the new marketing bundle if you need ongoing rule revisions.

Setup relies on the npx skills CLI or placing the markdown prompt directly into your agent configuration folder. No external API keys are required.

What it helps with

  • audit on-page SEO metrics on a target landing page
  • inspect metadata, titles, and heading hierarchy
  • identify missing content optimization elements
  • configure SEO audit guidelines across supported AI editors

Example prompts for the agent

  • Run an on-page SEO audit on index.html and list all missing metadata.
  • Review the heading structure and content hierarchy of this landing page.
  • Audit the current page according to on-page-seo-auditor guidelines.
