Sitemap segmenter: split large sitemaps for faster Google discovery.
Sitemap segmentation by content type is a 2026-recommended technique for improving crawl discovery and indexing speed. Search Console gives you per-segment indexing status, faster recrawl on segments that change frequently, and better visibility into which content types are indexed vs not.
About this tool.
Sitemap segmentation by content type is a 2026-recommended technique. Google Search Console provides per-sitemap indexing reports, so segmenting by type (sitemap-blog.xml, sitemap-tools.xml, sitemap-locations.xml) lets you see which content types are indexed at what rate. This visibility alone catches problems that would be invisible in a monolithic sitemap.
Beyond visibility, segmented sitemaps with accurate per-segment lastmod values compress Google's crawl interval on actively-updated segments. A blog sitemap updated weekly gets recrawled weekly. A reference-library sitemap updated quarterly gets recrawled quarterly. This is more efficient for both your server and Google.
The sitemap protocol limits each sitemap file to 50,000 URLs and 50MB uncompressed. Above either limit, you must segment. But the right segmentation strategy for sites under those limits is by content type, not by URL count.
A sitemap-index.xml at the root references all segmented sitemaps. Search engines fetch the index first, then fetch each segmented sitemap. This is the same pattern Google's own properties use (try google.com/sitemap.xml — it returns an index referencing 100 plus segmented sitemaps).
ThatDeveloperGuy segments every client sitemap by content type. The most common segments: pages (top-level pages), blog (articles), services (service pages), locations (city/region pages), industries (vertical pages), tools (utility pages), reference (canonical docs), case-studies (portfolio entries). Plus the standard sitemap-image.xml and sitemap-video.xml for media-specific sitemaps.
This tool segments client-side from the sitemap content you paste. For production deployment, you need to write each segment to its corresponding file on your server and update the sitemap-index.xml at the root. Submit each segment plus the index to Google Search Console for full per-segment reporting.
FAQ.
Why segment my sitemap?
Faster discovery, per-segment GSC reporting, more efficient recrawl scheduling, easier debugging. A single 50,000-URL sitemap gives you one number; ten 5,000-URL segments give you ten data points to diagnose problems.
How many segments is too many?
Google supports up to 500 sitemaps per sitemap-index. Practical limit: 10-30 segments for most sites. Don't segment so finely that each sitemap has under 50 URLs.
Do I need to submit each segment to GSC?
Yes if you want per-segment reporting. Submit each segment individually via GSC > Sitemaps. Also submit the sitemap-index.xml for redundancy.
Does segmentation affect crawl budget?
Slightly positively. Google can schedule recrawls per segment based on actual lastmod patterns. Properly segmented sites with accurate lastmod see ~15-25% faster impression onset on new content.
What if my sitemap is under 50K URLs?
Segment anyway. The reporting benefit alone is worth it. ThatDeveloperGuy segments client sites starting at 50 URLs total.
Can I have one sitemap reference both pages and images?
Yes, using the image: namespace in your URL entries. But for cleaner reporting, keep a separate sitemap-image.xml. Google reads both correctly.
