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

2. On-Page Metadata, structure, schema title-tag, meta-description, page-metadata, schema-markup, internal-links, heading-structure

3. Content Gaps, intent, optimization keyword-research, content-strategy, content-optimization

4. Off-Page Backlinks, authority link-building, backlink-analysis

Principle: Fix foundation before optimizing pages. See seo-strategy for workflow and prioritization.
