SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? XML sitemaps often contain broken URLs, non-canonical pages, or structural errors that hurt search engine crawling, and building a new sitemap from scratch requires knowing protocol limits and SEO best practices. ## Core Features & Use Cases - Sitemap Validation: Checks XML format, URL count limits (50,000 per file), HTTP status codes, lastmod accuracy, and flags non-canonical, noindexed, or redirected URLs. - Sitemap Generation: Creates new sitemaps from industry templates with quality gates that warn about thin programmatic pages (e.g., location pages at scale) and automatically splits large sites with a sitemap index. - Use Case: An SEO specialist auditing a client's site can validate the existing sitemap, receive a severity-ranked issue report in VALIDATION-REPORT.md, then generate a clean replacement sitemap split by content type. ## Quick Start Analyze the sitemap at https://example.com/sitemap.xml and report any validation issues.

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 XML sitemap for SEO issues?▼

Sitemap validation checks XML format correctness, HTTP 200 status for all URLs, accurate lastmod dates, and exclusion of non-canonical, noindexed, or redirected URLs. Issues are reported with severity levels from Critical to Info in a validation report.

How to generate a sitemap for a new website?▼

Sitemap generation starts by detecting the business type, loading an industry template, and planning the structure interactively. The output is valid XML split at 50,000 URLs with a sitemap index, plus a STRUCTURE.md documenting the site architecture.

What is the maximum number of URLs in a sitemap?▼

A single sitemap file supports a maximum of 50,000 URLs per the protocol limit. Larger sites must split URLs across multiple sitemap files referenced by a sitemap index file, typically organized by content type.

Should I include priority and changefreq tags in my sitemap?▼

The priority and changefreq tags are ignored by Google and can be safely removed from sitemaps. Validation flags them as informational issues only, with no impact on crawling or indexing.

Why are noindexed or redirected URLs a problem in sitemaps?▼

Noindexed and redirected URLs in a sitemap send conflicting signals to search engines and waste crawl budget. Validation flags noindexed URLs as high severity and redirected URLs as medium severity, recommending removal or updating to final URLs.

When should I avoid generating programmatic pages at scale?▼

Avoid mass-generating location pages with only the city name swapped, competitor-alternative pages without real comparison data, or unreviewed AI-generated content. The generation workflow warns at 30+ location pages and hard-stops at 50+ without justification.
