Sitemap Index Generator — Create Sitemap Index Files Free
Create a valid sitemap index file that references multiple individual sitemaps. Essential for large websites exceeding the 50,000 URL limit.
The sitemaps.org rules cap each XML sitemap at 50,000 URLs and about 50 MB uncompressed per file. If your site is larger, you cannot put every URL in a single sitemap.xml — you split the URLs across several child sitemaps and point search engines to them with one sitemap index file (a sitemapindex root element) that lists each child sitemap's loc URL.
This tool builds that index for you: enter the full public URLs of each child sitemap (for example sitemap-posts.xml and sitemap-products.xml on your domain), and download a standards-compliant sitemap-index.xml you can host at your domain root or wherever you serve sitemaps.
Pair it with the Sitemap Split & Merger tool when you already have one huge sitemap and need to slice it into multiple files under the limit, then paste those resulting sitemap URLs here to produce the index. Use the XML Sitemap Generator for net-new URL lists and the Sitemap Validator on each child file and on the index before you submit to Google Search Console.
