Sitemap Manager

Audit an existing XML sitemap — URL counts vs protocol limits, lastmod validity, sampled URL status codes, robots.txt and noindex conflicts, missing pages, compression — or generate a new sitemap (plan or valid XML with index splitting) from industry templates for SaaS, ecommerce, local, publisher, or agency sites.

Purpose

Analyze existing XML sitemaps for issues and opportunities, or generate new sitemaps with industry-specific templates and best practices.

Modes

Mode 1: Analyze Existing Sitemap (/digital-marketing-pro:sitemap-manager [URL])

Provide a sitemap URL (e.g., https://example.com/sitemap.xml) to audit:

  1. Fetch and parse: Download sitemap XML, detect sitemap index vs single sitemap
  2. URL count: Total URLs, URLs per sitemap file (flag if approaching 50K protocol limit)
  3. lastmod audit: Check for presence, format (W3C datetime), staleness (>6 months without update), fake lastmod (all same date)
  4. Priority and changefreq: Check for deprecated/ignored signals (Google ignores both — flag if present, recommend removal to reduce file size)
  5. URL health: Sample 20-50 URLs and check HTTP status codes — flag 404s, 301s, 302s, 5xx errors
  6. Indexation alignment: Cross-reference with robots.txt and meta robots — flag noindexed URLs in sitemap, flag sitemap URLs blocked by robots.txt
  7. Missing URLs: Compare sitemap against site crawl or provided URL list — identify pages missing from sitemap
  8. Image/video/news sitemaps: Check for specialized sitemap extensions
  9. Compression: Check if sitemap is gzip compressed (recommended for large sitemaps)
  10. robots.txt registration: Verify sitemap is declared in robots.txt

Mode 2: Generate New Sitemap (/digital-marketing-pro:sitemap-manager generate)

Generate a sitemap plan or actual XML:

  1. Discover site structure: Crawl from homepage or use provided URL list
  2. Categorize pages: Group by type (homepage, category, product, blog, landing, legal)
  3. Apply industry template: Use appropriate structure based on business model (SaaS, ecommerce, local, publisher, agency)
  4. Set lastmod: Use actual page modification dates, not generation date
  5. Split strategy: Plan sitemap index structure if >50K URLs or >50MB uncompressed
  6. Exclude rules: Noindexed pages, paginated results, faceted URLs, utility pages (login, cart, search results)
  7. Generate XML: Produce valid XML sitemap following the sitemap protocol (sitemaps.org)
