Strategies: SEO Audit#

Guides end-to-end SEO audit: technical foundation, on-page, content, and off-page. Execute in order—technical blockers prevent indexing; on-page limits rankings; content and off-page build authority. Use when auditing an existing site or planning fixes.

When invoking: On first use, if helpful, open with 1–2 sentences on what this skill covers and why it matters, then provide the main output. On subsequent use or when the user asks to skip, go directly to the main output.
