SEO Audit, Fix, and Verification

Use this for technical site-quality work where the expected output is evidence-backed fixes, not a generic checklist. Scope is technical SEO plus the three other Lighthouse categories — performance, accessibility, best-practices — audited and iterated together with Ahrefs/GSC/Squirrel SEO evidence. Not content, keyword, or marketing strategy.

Author in a worktree. When this skill edits repo files (robots.txt, sitemaps, canonicals, config) — work in a git worktree off main, never the primary checkout on the main branch (rules/worktree-authoring.md). Integrate with /ship.

Required first reads

1. Read references/evals.md if you are changing this skill.
2. Read references/orchestration.md before any full /seo run.
3. Read references/issue-triage.md before classifying findings.
4. Read references/tooling.md before using Ahrefs, GSC, Squirrel, Lighthouse, sitemap submission, IndexNow, or browser automation.
5. Read references/report-template.md before final reporting.
6. Read references/ai-surfaces.md before answering anything about AI Overviews, AI Mode, or ChatGPT/Perplexity visibility (llms.txt, AI crawlers, snippet eligibility, schema-for-AI).

Operating principle

Start from crawler/search-console/Lighthouse evidence, classify findings before editing, fix only code/config defects, then verify after deployment with a fresh crawl, inspection, or Lighthouse re-run.
