SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes assets (resource) components.

What problem does it solve?

It prevents sitemap-related SEO failures by analyzing existing XML sitemaps for validity, coverage, and Google-relevant issues, or generating a correct, template-based sitemap with guardrails.

Core Features & Use Cases

  • Sitemap validation: Checks XML correctness, URL counts, HTTP 200 reachability, lastmod accuracy, and removes problematic entries like noindex, redirected, and non-canonical URLs.
  • Coverage and crawl consistency: Compares crawled pages against the sitemap and flags missing pages.
  • Sitemap generation with quality gates: Generates new sitemaps (including split sitemap index behavior) and produces STRUCTURE.md documentation using industry templates while applying scale-based stopping/warning rules for location-page content.

Quick Start

Ask to analyze or generate a sitemap by saying: Analyze https://example.com/sitemap.xml and report issues and fixes.

FAQPage Schema
How do I validate an XML sitemap for SEO errors and URL reachability?

XML sitemap validation checks URL correctness, HTTP 200 reachability, and lastmod accuracy while removing problematic entries like redirected or non-canonical URLs to ensure search-engine-ready URL discovery.

What is the best way to generate an XML sitemap for a large website?

Generating an XML sitemap for large websites uses industry templates with quality gates, applying scale-based stopping rules and split sitemap index behavior to output valid XML and STRUCTURE documentation.

How do I check sitemap coverage and crawl consistency against my actual website pages?

Checking sitemap coverage compares crawled pages against the existing sitemap entries to flag missing pages, verifying crawl consistency and ensuring all relevant website content is discovered by search engines.

Do I need to remove noindex or redirected URLs from my XML sitemap?

Yes, XML sitemap validation removes problematic entries including noindex, redirected, and non-canonical URLs to ensure search engines only discover and index valid, canonical pages during the crawling process.

When should I split my XML sitemap into a sitemap index?

Splitting an XML sitemap into a sitemap index is required when applying formatting rules for HTTPS-only URLs and scale-based stopping rules, ensuring generated sitemaps remain valid and manageable for search engine processing.

Can I generate a sitemap with structure documentation for location pages?

Yes, sitemap generation produces STRUCTURE.md documentation using industry templates while applying scale-based stopping and warning rules specifically for location-page content to prevent sitemap bloat and ensure structured URL indexing.
