FAQ
Is this a Google Search Console sitemap test?
No. This tool validates sitemap XML structure and common Google-compatible rules offline; it doesn’t submit or fetch anything.
What sitemap types does it support?
Standard <urlset> sitemaps and <sitemapindex> indexes.
Why does it warn about lastmod?
Google expects ISO 8601 formatting. Wrong formats can be ignored or cause parsing issues.
Does a valid sitemap guarantee indexing in Google?
No. A sitemap helps discovery, but indexing depends on crawlability, quality, canonicalization, and robots/noindex signals.
What are the common Google limits for sitemaps?
Common limits are 50,000 URLs per sitemap and about 50 MB uncompressed; use a sitemap index when you exceed them.
Why is http:// flagged?
It’s a warning because most sites prefer HTTPS. If your canonical URLs are HTTP, keep it consistent and ensure redirects are correct.
Should URLs with # fragments be in a sitemap?
Usually no—fragments aren’t separate crawl targets. Use clean URLs without #.
