Description
Use when analyzing or generating XML sitemaps and robots.txt. Not for redirect analysis (seo-redirects).
<objective> Fetches and validates `/sitemap.xml` (or sitemap index) via `scripts/parse-sitemap.ts`, cross-checks URL coverage against crawled pages to detect orphan URLs (in sitemap but not linked) and missing URLs (linked but not in sitemap), and covers the special sitemap types — sitemap-news.xml for publishers (last-48h articles only), sitemap-image.xml, sitemap-video.xml — plus best practices (50,000 URL / 50 MB cap per sitemap, real `<lastmod>` file dates, HTTPS absolute URLs, robots.txt sitemap reference). Templates in `templates/sitemap/` and `templates/robots/`. </objective>

Sitemap

Workflow

  1. Fetch /sitemap.xml (or sitemap index)
  2. Run scripts/parse-sitemap.ts → validate structure
  3. Cross-check URL coverage vs crawled pages
  4. Detect orphan URLs (in sitemap but not linked)
  5. Detect missing URLs (linked but not in sitemap)

Best Practices

  • Max 50,000 URLs or 50 MB per sitemap (use index if larger)
  • <lastmod> actual file modification date (not generation date)
  • <priority> and <changefreq> largely ignored by Google
  • HTTPS only, absolute URLs
  • Reference in robots.txt: Sitemap: https://example.com/sitemap.xml

Special Sitemaps

  • News (publishers): sitemap-news.xml, only articles from last 48h
  • Image: sitemap-image.xml with <image:image> tags
  • Video: sitemap-video.xml with <video:video> tags

Templates

  • templates/sitemap/sitemap.xml
  • templates/sitemap/sitemap-news.xml
  • templates/sitemap/sitemap-image.xml
  • templates/robots/robots-saas.txt
  • templates/robots/robots-ecommerce.txt
