SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

XML sitemaps are essential for SEO, but many sites face format errors, broken URLs, and inefficient indexing. This Skill analyzes existing sitemaps and generates new ones using industry templates to ensure proper crawlability and indexing.

Core Features & Use Cases

  • Analyze existing sitemap: validate XML syntax, ensure <loc> URLs are accessible (HTTP 200), check URL count limits, verify lastmod accuracy, and flag deprecated tags or non-canonical URLs.
  • Generate new sitemap: build sitemap.xml or split into sitemap index for large sites (>50k URLs), apply industry templates, and produce a STRUCTURE.md documenting site architecture.
  • Quality checks & issues: detect common issues (exceeding URL limits, mixed HTTP/HTTPS, missing sitemap reference in robots.txt).

Quick Start

To start, provide a site URL or an existing sitemap URL and choose Analyze to validate or Generate to create a new sitemap.

Frequently Asked Questions about seo-sitemap

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I validate an existing XML sitemap for broken URLs and syntax errors?▼

To validate an XML sitemap, you can analyze it to check XML syntax, ensure <loc> URLs return HTTP 200, verify URL count limits, and flag deprecated tags or non-canonical URLs. This ensures proper crawlability and indexing.

What is the best way to generate a standards-compliant sitemap for a large site?▼

Generating a standards-compliant sitemap for large sites involves building a sitemap.xml or splitting it into a sitemap index for over 50,000 URLs, applying industry templates, and outputting a STRUCTURE.md documenting site architecture.

Why does my XML sitemap fail search engine crawling checks?▼

An XML sitemap may fail crawling checks due to common issues like exceeding URL count limits, mixed HTTP/HTTPS protocols, missing sitemap references in robots.txt, or inaccurate lastmod dates flagged during analysis.

Can I check if my sitemap URLs are accessible and return HTTP 200?▼

Yes, you can check if sitemap URLs are accessible by analyzing the sitemap to verify that each <loc> URL returns an HTTP 200 status, which confirms the links are healthy for search engine crawlers.

When do I need a sitemap index instead of a single sitemap.xml file?▼

You need a sitemap index instead of a single sitemap.xml file when your site exceeds 50,000 URLs, requiring the sitemap to be split to comply with search engine indexing limits and ensure efficient crawling.
