A compressed sitemap file (.xml.gz) that reduces bandwidth and speeds up sitemap delivery.
A gzipped sitemap is a standard XML sitemap compressed using gzip to reduce file size. The file typically has the extension `.xml.gz` (e.g., `sitemap.xml.gz`). Search engines support gzipped sitemaps natively.
Gzip compression is especially useful for large sitemaps approaching the 50MB uncompressed limit. A typical sitemap compresses to about 10-20% of its original size.
When using gzipped sitemaps, the `Sitemap:` directive in robots.txt should reference the compressed file URL. The server should also serve the file with the correct `Content-Encoding: gzip` header.
SitemapKit's extract endpoint automatically handles gzipped sitemaps, decompressing them before parsing.
SitemapKit's API lets you discover, extract, and parse XML sitemaps from any domain. Get structured JSON data with all sitemap elements including Gzipped Sitemap.
