Sitemap Analysis & Generation

When to Use

Use when analyzing an existing XML sitemap or generating a new one.
Use when the user mentions sitemap issues, sitemap generation, or sitemap validation.
Use when checking URL coverage, sitemap limits, and sitemap quality rules.

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

Ask for business type (or auto-detect from existing site)
Load industry template from ../seo-plan/assets/ directory
Interactive structure planning with user
Apply quality gates:
- ⚠️ WARNING at 30+ location pages (require 60%+ unique content)
- 🛑 HARD STOP at 50+ location pages (require justification)
Generate valid XML output
Split at 50k URLs with sitemap index
Generate STRUCTURE.md documentation

Safe Programmatic Pages (OK at scale)

✅ Integration pages (with real setup docs) ✅ Template/tool pages (with downloadable content) ✅ Glossary pages (200+ word definitions) ✅ Product pages (unique specs, reviews) ✅ User profile pages (user-generated content)

Penalty Risk (avoid at scale)

❌ Location pages with only city name swapped ❌ "Best [tool] for [industry]" without industry-specific value ❌ "[Competitor] alternative" without real comparison data ❌ AI-generated pages without human review and unique value

Sitemap Format

Standard Sitemap

<?xml version="1.0" encoding="UTF-8"?>
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
  <url>
    <loc>https://example.com/page</loc>
    <lastmod>2026-02-07</lastmod>
  </url>
</urlset>

Sitemap Index (for >50k URLs)

<?xml version="1.0" encoding="UTF-8"?>
<sitemapindex xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
  <sitemap>
    <loc>https://example.com/sitemap-pages.xml</loc>
    <lastmod>2026-02-07</lastmod>
  </sitemap>
  <sitemap>
    <loc>https://example.com/sitemap-posts.xml</loc>
    <lastmod>2026-02-07</lastmod>
  </sitemap>
</sitemapindex>

Error Handling

URL unreachable: Report the HTTP status code and suggest checking if the site is live
No sitemap found: Check common locations (/sitemap.xml, /sitemap_index.xml, robots.txt reference) before reporting "not found"
Invalid XML format: Report specific parsing errors with line numbers
Rate limiting detected: Back off and report partial results with a note about retry timing

Output

For Analysis

VALIDATION-REPORT.md: analysis results
Issues list with severity
Recommendations

For Generation

sitemap.xml (or split files with index)
STRUCTURE.md: site architecture documentation
URL count and organization summary

Limitations

Use this skill only when the task clearly matches the scope described above.
Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.
