IndexNow for Bing: Key File Setup & Batch Submission

What is IndexNow (Bing)?

IndexNow lets you proactively notify search engines about URL updates. This site currently sends requests to the Bing IndexNow endpoint only.

Prerequisites

You need:

• An IndexNow key
• A publicly accessible key file on your site

1) Host the key file

The key file must be reachable at:

https://<host>/<key>.txt

Its content must be the key only:

<key>

2) Submit URLs

When submitting, all URLs must:

• Be valid http(s) URLs
• Belong to the same hostname

You can use this UI, or send the request yourself:

curl -X POST "https://www.bing.com/indexnow" \
  -H "Content-Type: application/json; charset=utf-8" \
  -d '{
    "host": "www.example.com",
    "key": "your-indexnow-key",
    "keyLocation": "https://www.example.com/your-indexnow-key.txt",
    "urlList": [
      "https://www.example.com/page-1",
      "https://www.example.com/page-2"
    ]
  }'

Common errors

• 403: key is invalid or the key file is not accessible
• 422: URL list is invalid, or URLs do not match the host
• 429: rate limited, retry later

Tips

• Submit one site per request (do not mix hosts).
• Keep the key file URL and the submitted host consistent.
• Start with a small batch to validate the setup.
