Seo Sitemap

Sitemap Analysis & Generation

Mode 1: Analyze Existing Sitemap

Validation Checks

• Valid XML format
• URL count ` dates are accurate (not all identical)
• No deprecated tags: ` and ` 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 template from ../seo-plan/assets/ directory
3. Interactive structure planning with user
4. Apply quality gates:

• ⚠️ WARNING at 30+ location pages (require 60%+ unique content)
• 🛑 HARD STOP at 50+ location pages (require justification)

1. Generate valid XML output
2. Split at 50k URLs with sitemap index
3. 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

  
    https://example.com/page
    2026-02-07
  

Sitemap Index (for >50k URLs)

  
    https://example.com/sitemap-pages.xml
    2026-02-07
  
  
    https://example.com/sitemap-posts.xml
    2026-02-07
  

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
