Guide

Stay under sitemap file limits

Google and Bing document ~50,000 URLs or 50MB per sitemap file. Split before you hit either ceiling.

Name child files consistently (sitemap-1.xml …) and point robots.txt at the index, not every child.

After deploying chunks, validate with the sitemap checker.

Questions

Split / Merge FAQ

Do you crawl my website?

No. These builders work from pasted URLs or XML in your browser - safer and faster for founder workflows.

What is the 50,000 URL limit?

Google and Bing document a soft per-file limit of 50,000 URLs (or 50MB). Split large lists, then point robots.txt at an index. See the sitemap checker.

Where should I host the file?

At a public HTTPS URL referenced by a Sitemap: line in robots.txt (often /sitemap.xml or /sitemap_index.xml).

XML Sitemap Generator

Generate a urlset XML sitemap from a pasted URL list - optional changefreq, priority, and lastmod.

Sitemap Index Generator

Build a sitemapindex XML file from a list of child sitemap URLs.

Sitemap Validator

Validate XML sitemaps for fetch errors, soft limits, and bad loc/lastmod/changefreq/priority values.

Robots.txt Generator

Build a clean robots.txt with sitemap URL, disallow paths, and optional AI-scraper blocks.
