Understand the difference between a sitemap index file and individual sitemap files in the XML sitemap protocol.
This page compares Sitemap Index and Individual Sitemap using the documented strengths, limitations, and practical fit recorded for each option. Descriptive claims are kept separate from measured benchmarks; a benchmark is shown only when its test conditions are available.
Choose Sitemap Index when your priority is references multiple sitemap files.
Choose Individual Sitemap when your priority is simple — one file with all urls.
Use a single sitemap file for sites under 50,000 URLs. Use a sitemap index when you need to split URLs across multiple files — this is standard for any site with significant content volume.
