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:
- Fetch and parse: Download sitemap XML, detect sitemap index vs single sitemap
- URL count: Total URLs, URLs per sitemap file (flag if approaching 50K protocol limit)
- lastmod audit: Check for presence, format (W3C datetime), staleness (>6 months without update), fake lastmod (all same date)
- Priority and changefreq: Check for deprecated/ignored signals (Google ignores both — flag if present, recommend removal to reduce file size)
- URL health: Sample 20-50 URLs and check HTTP status codes — flag 404s, 301s, 302s, 5xx errors
- Indexation alignment: Cross-reference with robots.txt and meta robots — flag noindexed URLs in sitemap, flag sitemap URLs blocked by robots.txt
- Missing URLs: Compare sitemap against site crawl or provided URL list — identify pages missing from sitemap
- Image/video/news sitemaps: Check for specialized sitemap extensions
- Compression: Check if sitemap is gzip compressed (recommended for large sitemaps)
- 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:
- Discover site structure: Crawl from homepage or use provided URL list
- Categorize pages: Group by type (homepage, category, product, blog, landing, legal)
- Apply industry template: Use appropriate structure based on business model (SaaS, ecommerce, local, publisher, agency)
- Set lastmod: Use actual page modification dates, not generation date
- Split strategy: Plan sitemap index structure if >50K URLs or >50MB uncompressed
- Exclude rules: Noindexed pages, paginated results, faceted URLs, utility pages (login, cart, search results)
- Generate XML: Produce valid XML sitemap following the sitemap protocol (sitemaps.org)
