Paste a sitemap and see every problem at once, with what it means and how to fix it. It counts the URLs and checks dates, duplicates and limits.

This is an interactive tool. Use it at https://promptitin.com/free-tools/sitemap-checker.

## How to use it

1. Open yoursite.com/sitemap.xml in your browser, view the page source and copy all of it.
2. Paste it in the box, or open the saved file. Tap Try an example to see how it works.
3. Read the problems first, then the warnings. Each one says how to fix it.

## Tips

- List only pages you want in search: no redirects, no noindex pages, no duplicates.
- Use real lastmod dates. Search engines stop trusting them if every page changes every day.
- Google ignores changefreq and priority, so you can leave them out.
- Large sites can split pages across several sitemaps and list them in a sitemap index.

## FAQ

### Why can't I enter my sitemap's URL?

The checker runs in your browser and doesn't fetch other sites. Open the sitemap, copy its source and paste it, which takes a few seconds.

### What are the sitemap limits?

50,000 URLs and 50 MB uncompressed per sitemap. Bigger sites split their URLs across several sitemaps listed in a sitemap index.

### Does it check if my pages load?

No. It checks the sitemap itself. For crawl errors on the pages, use the Pages report in Google Search Console.

### Does it work with sitemap index files?

Yes. It checks the list of sitemaps, and you can paste each child sitemap to check its pages.
