  "summary": "Ask a coding agent to fetch your sitemap, request every URL, and check status codes, redirects, canonicals, noindex rules, robots.txt and internal links against the code that produces them. Make it sort the findings by what stops pages from being crawled or indexed, and tell it to skip health scores. Review each fix as a diff before you deploy. One founder reports that the agent found a robots rule that had blocked his whole site for weeks.\n",
  "outcome": "You get a ranked list of crawl and index problems, the file that causes each one, and fixes that you reviewed and deployed.",
  "difficulty": "intermediate",
  "time": "About 20 minutes to audit 40 pages, in one tester's report",
  "cost": "Included in a Claude Code, Codex or Cursor plan",
  "risk": "medium",
  "risk_note": "A wrong robots rule, canonical or redirect can remove pages from Google. Approve every change and check the live site after the deploy.",
  "human_checkpoints": [
    "Approve the list of fixes before the agent edits any file.",
    "Review every diff to robots.txt, canonicals, redirects and noindex rules before you deploy.",
    "Confirm that a redirect or a noindex rule is a mistake before the agent removes it. Some are on purpose."
  ],
  "prompt": "Audit [https://example.com] for technical SEO. The code that serves the site is in this repository.\n\n1. Fetch [https://example.com/sitemap.xml] and /robots.txt. Request every URL in the sitemap, and every internal link you find on those pages. Send no more than [2] requests per second.\n2. For each URL, record: status code, final URL after redirects, number of redirect hops, canonical tag, meta robots tag, X-Robots-Tag header, title, meta description, H1, and the number of internal links that point to it.\n3. Check the host rules: http must 301 to https, and www and non-www must 301 to one host. Check that the trailing-slash rule is the same on every page.\n4. For [3] page templates, compare the raw HTML with the rendered page. Flag any main content or navigation that only appears after JavaScript runs.\n5. Group the findings in this order:\n   a. Blocks crawling or indexing (robots rules, noindex on real pages, 4xx or 5xx pages that get links).\n   b. Sends Google conflicting signals (a canonical that points to a redirect or a noindex page, sitemap URLs that redirect or return 404).\n   c. Weak pages (missing or duplicate titles, pages with 0 to 2 internal links).\n   d. Minor items.\n   Do not give a health score.\n6. For each finding, name the file or setting that causes it and propose the smallest fix.\n7. Write everything to [seo/audit-YYYY-MM-DD.md]. Then stop and wait for my approval before you change any file.\n",
