What technical-seo-checker does

This skill provides technical SEO and page optimization checks directly inside an AI coding assistant. Originally developed in the aaron-he-zhu/seo-geo-claude-skills repository under optimize/technical-seo-checker, the standalone codebase has stopped receiving updates. That repository now serves as a signpost, leaving behind a frozen standalone copy tagged v9.9.12.

Active development moved to the aaron-marketing-skills bundle at path seo-geo/optimize/technical-seo-checker. This is a direct reason to install the skill from the active bundle rather than staying on frozen code.

You can install the skill with npx skills add or gh skill install. Manual setup is also supported by placing SKILL.md into the agent's configuration directory. The project is licensed under Apache-2.0.

What it helps with

audit technical SEO issues in a project
run page optimization checks through an AI assistant
configure technical SEO guidelines in Claude Code
migrate from the deprecated standalone repo to the active bundle

Example prompts for the agent
