Issue with IndexNow Automatic Submission Indexing ‘noindex’ Pages

I’ve noticed something similar, especially when using IndexNow in combination with dynamic CMS platforms.

From what I’ve gathered, IndexNow just submits the URL, but doesn’t necessarily re-check meta directives like noindex immediately. So if a page was temporarily missing the noindex tag (e.g., during deploy or cache rebuild), it may have been indexed before the correct directive was applied.

A couple of things that helped me:

- Make sure the noindex header or tag is present consistently — both on initial load and when crawled without cookies or JS.
- Double-check your server’s cache/CDN settings. I once found that the edge cache was serving an outdated version *without* the noindex, even though the origin was correct.
- Use the Bing URL Inspection Tool to see the current status — it sometimes shows when a URL was last crawled and what directives were seen.

Would be great if Microsoft shared more transparency on how quickly IndexNow honors updated noindex signals after submission.

Let us know if you find a reliable fix — this seems like an area a lot of SEOs are still trying to fully understand.
