XML Sitemap too big: Splitting Sitemap files
Too large sitemaps must be separated into several files and a sitemap index.
Too large sitemaps must be separated into several files and a sitemap index The sitemap is a control signal. It should only contain URLs that are reachable, relevant and meaningfully indexable from an SEO point of view.
Control file size and URL number separately
A large sitemap can either contain too many entries or become too large due to extensive extensions. Check both sizes on the uncompressed XML file. Divide the export meaningfully, for example by content type or stable URL groups, and merge the parts into a sitemap index.
Example: Recognizing the Result
Illustrative example: A sitemap grows through variants and contains more URLs than a single file can hold. Compression does not solve the exceeding of the URL number.
Limit cause and implement correction
Check that each part file is reachable and no URL is lost due to the splitting or is unintentionally output multiple times. The index must state the actual published file names. Also test the next regular export; a one-time manual division does not fix a generator, which then writes a single oversized file again.
What makes you recognize a suitable correction
Clean up the selection and distribute it to limited sub-sitemaps; validate the sitemap index as well as any file after export.
Classification and boundaries
When is this indication not a clear error?
For a single sitemap, a maximum of 50,000 URLs and 50 MB of uncompressed file size apply. Respect both boundaries independently of each other.
XML sitemap too large according to CMS and cause
Many audit messages can be resolved faster if they are grouped by system, page type and technical cause. CMS indentations are only linked where XML sitemap has a clear cause or fixed route in the respective system.
For this error, there is currently no own CMS deepening, because the correction is usually not sufficiently system-specific. Take advantage of the general causes and checks on this page.
