IndexNow — Bing URL 送信・キー確認・ステータスコード

IndexNow キーを生成し、検証用 txt をダウンロード、公開ファイルの一致を確認してから変更 URL を Bing 等へ送信します。手順とステータス表（200 と 202）、JSON 例を確認してください。変更通知はインデックス保証ではありません。

HTTP 202 means the endpoint accepted a well-formed request — not that your key file already passed verification. Always Check key first. IndexNow notifies discovery; it does not guarantee indexing or rankings.

Host (must match your URLs)

IndexNow key

keyLocation (optional)

Default is https://{host}/{key}.txt on the same host. www and apex are different hosts.

Endpoint

URL list or sitemap XML

All URLs must use the same host. Max 500 URLs per submit in this tool.

Result / payload preview

使い方

1) Generate a key and download {key}.txt. 2) Host it at your site root (or another path on the same host). 3) Check key so this Worker can fetch and match the body. 4) Paste changed URLs (or sitemap XML), preview the JSON, then Submit. Confirm receipts in Bing Webmaster → IndexNow.

守るべきルール

Protocol rules for keys, hosts, status codes, and what IndexNow does not promise.

Key: 8–128 characters from [A-Za-z0-9-]. Option 1 (recommended): host UTF-8 text at https://{host}/{key}.txt containing only the key.
host in the JSON must equal the hostname of every URL and of keyLocation. www.example.com and example.com are different hosts.
200 = received; 202 = accepted with key validation often still pending (Bing/global). A green 202 is not proof the key file works — use Check key.
Protocol allows up to 10,000 URLs per POST; this page caps at 500 to reduce abuse. Prefer submitting only changed URLs.
Privacy: URL lists are sent through this site’s Worker to the IndexNow endpoint you choose, then discarded from our side — we do not store them in a content database.

例

Host www.example.com, key indexnowdemokey01, URL https://www.example.com/page → POST JSON with host, key, keyLocation https://www.example.com/indexnowdemokey01.txt, and urlList. After hosting the .txt, Check key should report HTTP 200 and bodyMatch true before Submit.

向いている場面

New site or tool launch: deploy the key file, check it, then submit the new URLs from your sitemap.
Content update: submit only the pages you changed instead of the whole site every time.
Removed pages: submit URLs that now return 404/410 so engines can recrawl sooner.

HTTP ステータス

What common IndexNow responses mean and what to do next.

Code	Meaning	Next step
200	OK — URLs received	Optional: confirm in Bing Webmaster IndexNow log
202	Accepted — key validation may still be pending	Verify the live key file; do not assume success from 202 alone
400	Bad request — invalid format	Fix JSON/URL encoding and retry
403	Forbidden — key not valid	Fix key file path, body, or blocking (auth/HTML error)
422	Unprocessable — URL/host/key schema mismatch	Align host and URLs; check key character rules
429	Too many requests	Wait and reduce batch frequency

Frequently asked questions

HTTP 202 は成功ですか？

形式が正しいリクエストを受け付けたという意味です。Bing/グローバルではキー検証が後から行われることがあります。先にキーを確認してください。

Where do I put the key file?

Preferred: site root as https://your-host/{key}.txt with the key as the only body text. You may use another path on the same host via keyLocation; Option 2 also limits which URL prefixes that key can cover.

Why does www vs non-www matter?

They are different hosts. If URLs use www, the key file must be on www (and the host field must be www). Fix DNS/canonical hosts first if you are unsure.

IndexNow はインデックスを保証しますか？

しません。変更の通知のみです。

Do you store my URL list?

No content database. The Worker forwards your JSON to IndexNow/Bing for the request and does not publish the list as a public page.
