SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps you prevent SEO crawl/indexing issues by validating existing XML sitemaps and producing clean, industry-aligned sitemaps that search engines can consume reliably.

Core Features & Use Cases

  • Sitemap validation: Checks XML structure, URL reachability (HTTP 200), lastmod quality, robots.txt linkage, and canonical/HTTPS compliance while flagging common sitemap problems.
  • Safe generation: Produces standards-compliant sitemap.xml (or split sitemap indexes) using templates, with quality gates to reduce spammy or low-value URL patterns.
  • Issue reporting & documentation: Outputs validation reports and generation artifacts such as a STRUCTURE.md describing the site architecture.

Quick Start

Use the seo-sitemap skill to analyze the sitemap at https://example.com/sitemap.xml and return a prioritized list of issues and fixes.

FAQPage Schema
How do I validate an XML sitemap for crawl and indexing issues?▼

Validating an XML sitemap involves checking XML structure, URL reachability for HTTP 200 responses, lastmod accuracy, robots.txt linkage, and HTTPS canonical compliance to prevent search engine indexing issues.

What does a sitemap audit check for URL quality and robots.txt compliance?▼

A sitemap audit checks URL quality by verifying HTTP 200 reachability, enforcing HTTPS-only canonical constraints, validating lastmod tags, confirming robots.txt linkage, and flagging common XML formatting problems.

How do I generate a standards-compliant XML sitemap index for large sites?▼

Generate a compliant sitemap index by using templates to split URLs into separate indexes, applying quality gates to exclude spammy URL patterns, and enforcing strict XML formatting rules for pages, images, and videos.

Does sitemap generation support images, videos, and location URLs?▼

Sitemap generation supports production-ready XML outputs containing pages, posts, images, videos, and locations while enforcing HTTPS-only canonical URL constraints and strict XML formatting rules.

Why does lastmod validation matter for XML sitemaps?▼

Lastmod validation matters because accurate lastmod tags improve crawl reliability by signaling content freshness to search engines, helping prioritize indexing for updated URLs during the site crawling process.

What is the best way to fix common XML sitemap errors and structure problems?▼

The best way to fix XML sitemap errors is to run a validation audit that flags structural issues, checks robots.txt linkage, verifies URL health, and outputs a prioritized list of issues with structured documentation.
