# 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.

## Audit Order

| Phase | Focus | Skills |
|-------|-------|--------|
| **1. Technical** | Crawl, index, sitemap | robots-txt, xml-sitemap, canonical-tag, indexing, site-crawlability |

Audit Order

Phase	Focus	Skills
1. Technical	Crawl, index, sitemap	robots-txt, xml-sitemap, canonical-tag, indexing, site-crawlability
