💡 Tips

Use XML sitemap for Google (better supported)
JSON useful for internal tools
Include lastmod for frequently updated pages
Priority is relative within your site
Split large sitemaps (50k URLs max)

⚠️ Common Pitfalls

Google doesn't officially support JSON sitemaps
Use XML sitemap.xml for SEO
lastmod should be ISO 8601 date
changefreq is just a hint
