Sitemap Generator - Online XML Sitemap Builder

1. Generate a sitemap

URLs must be absolute (https://…). This emits a static map; add real lastmod per page when updates matter — here it is a single default.

1. Paste one URL per line.
2. Pick default changefreq (e.g. weekly) and priority (0.0–1.0).
3. Download sitemap.xml, upload to the root, and submit to GSC/Bing.

2. Using priority / changefreq

Split into a sitemap index beyond 50k URLs or 50MB.

• Home ~1.0, core sections ~0.8, long-tail ~0.5.
• changefreq is a crawl hint, not a guarantee.
• Do not set everything to 1.0 — if all pages are top priority, none are.

3. Limits and next steps

Next: meta-tag-pixel-checker for SEO tags; open-graph-previewer for share cards.

• Multilingual sites need hreflang annotations (not generated here).
• Reference the sitemap in robots.txt so crawlers find it.
• Cross-check: robots.txt-generator can emit that reference.

4. lastmod honesty and index sitemaps

Search engines increasingly distrust lastmod stamps that change on every build regardless of content — a file that says everything changed daily teaches the crawler to ignore the field. Stamp lastmod only when page content materially changed, and let your generator derive it from the data source, not from build time. Past roughly 50,000 URLs, the spec wants a sitemap index file pointing at child sitemaps; most crawlers handle large single files, but the index structure also lets you split by update frequency so the hot section gets crawled on its own cadence. Verify with the search console before assuming ingestion — a sitemap that parses but is never crawled usually means the URLs redirect.
