Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# Sitemap Analysis & Generation ## Mode 1: Analyze Existing Sitemap ### Validation Checks - Valid XML format - URL count <50,000 per file (protocol limit) - All URLs return HTTP 200 - `<lastmod>` dates are accurate (not all identical) - No deprecated tags: `<priority>` and `<changefreq>` are ignored by Google - Sitemap referenced in robots.txt - Compare crawled pages vs sitemap; flag missing pages ### Quality Signals - Sitemap index file if >50k URLs - Split by content type (pages, posts, images, videos) - No non-canonical URLs in sitemap - No noindexed URLs in sitemap - No redirected URLs in sitemap - HTTPS URLs only (no HTTP) ### Common Issues | Issue | Severity | Fix | |-------|----------|-----| | >50k URLs in single file | Critical | Split with sitemap index | | Non-200 URLs | High | Remove or fix broken URLs | | Noindexed URLs included | High | Remove from sitemap | | Redirected URLs included | Medium | Update to final URLs | | All identical lastmod | Low | Use actual modification dates | | Priority/changefreq used | Info | Can remove (ignored by Google) | ## Mode 2: Generate New Sitemap ### Process 1. Ask for business type (or auto-detect from existing site) 2. Load industry

What does the seo-sitemap skill do?
Analyze existing XML sitemaps or generate new ones with industry templates. Validates format, URLs, and structure. Use when user says "sitemap", "generate sitemap", "sitemap issues", or "XML sitemap".
How do I install it?
Run `npx skills add Infrasity-Labs/dev-gtm-claude-skills --skill seo-sitemap --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From Infrasity-Labs/dev-gtm-claude-skills, a repository with 97 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
