WordPress sitemaps: core, Yoast, Rank Math and manual

WordPress already makes a sitemap. What matters is knowing which one is live, what it leaves out, and when a hand-built file should sit next to it.

Which sitemap is your site serving?

SetupSitemap URLNotes
WordPress core 5.5+/wp-sitemap.xmlNo lastmod on the index; includes user archives
Yoast SEO/sitemap_index.xmlDisables core; adds images and lastmod
Rank Math/sitemap_index.xmlDisables core; per-type toggles
All in One SEO/sitemap.xmlDisables core

Only one should be active. Two plugins each generating a sitemap, or core plus a plugin, leads to duplicate submissions and confusing Search Console reports.

Common WordPress sitemap problems

  • 404 on the sitemap URL. Flush permalinks (Settings → Permalinks → Save).
  • Blank page or XML error. A plugin or theme outputs whitespace before the XML. Deactivate plugins one by one, or check functions.php for a trailing newline after ?>.
  • Cached HTML version. Exclude *sitemap*.xml from page caching and minification.
  • Noindexed content listed. Check the post type settings in your SEO plugin; the sitemap should mirror what is indexable.

When to generate one by hand

For URLs outside WordPress's database: a static tool in /calculator/, a headless front end, a landing-page builder on a subpath, or a list of legacy URLs during a migration.

  1. Build the file with the generator (e.g. sitemap-extra.xml).
  2. Upload it to the web root over SFTP or your host's file manager.
  3. Add a second Sitemap: line in robots.txt, or submit it in Search Console.
Open the generator

Check what your plugin produces with the validator, or export its URLs with the extractor.

Questions people ask

Does WordPress have a built-in sitemap?
Yes. Since WordPress 5.5 core generates /wp-sitemap.xml, an index of posts, pages, custom post types, taxonomies and author archives. SEO plugins such as Yoast and Rank Math disable it and serve their own.
Where is my WordPress sitemap?
Try /sitemap_index.xml (Yoast, Rank Math), /wp-sitemap.xml (core) or /sitemap.xml (some plugins, often redirecting to one of the others). Or let the sitemap finder check them all.
Do I need a sitemap plugin?
Not necessarily. Core’s sitemap is valid and adequate for most blogs. SEO plugins add controls (exclude post types, image entries, a lastmod on the index) and remove things like user archives you may not want listed.
When would I use a manual sitemap on WordPress?
For URLs WordPress doesn’t know about: a static microsite in a subfolder, a headless front end, landing pages served by another app, or a one-off sitemap for a migration. Upload the generated file to the web root and add it to robots.txt next to the plugin’s sitemap.
Why does my WordPress sitemap show a 404?
Usually stale rewrite rules. Go to Settings → Permalinks and click Save without changing anything. Also check that a caching or security plugin isn’t intercepting the sitemap URL.
