Tell search engines what changed

Tell search engines that support IndexNow, such as Bing, Yandex and Seznam, about new and changed pages. Prove the site is yours with a key file served from it.

By Erik Bergstedt, Agent Wranglers. Updated 20 October 2026.

How to do it

Create a key of 8 to 128 letters, digits or dashes. Serve it as a text file at /<key>.txt, holding only the key. After each deploy, POST the changed URLs to https://api.indexnow.org/indexnow. Send the ping only after the new release passes its health check, or the search engine finds the key file missing and answers 403. Google does not use IndexNow, so keep the sitemap's lastmod honest too.

Example

curl -X POST https://api.indexnow.org/indexnow \
  -H 'Content-Type: application/json; charset=utf-8' \
  -d '{"host":"example.com","key":"a1b2c3d4e5f6","keyLocation":"https://example.com/a1b2c3d4e5f6.txt","urlList":["https://example.com/pricing"]}'

How to check

The API answers 200 or 202.
