IndexNow — enviar URLs a Bing, comprobar clave y códigos
Genera una clave IndexNow, descarga el .txt, comprueba que el archivo en vivo coincida y envía URLs cambiadas a Bing y motores participantes. Sigue los pasos, lee la tabla de estados (200 vs 202) y un ejemplo JSON: avisar un cambio no garantiza indexación.
Cómo funciona
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.
Reglas a tener en cuenta
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.
Ejemplo
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.
Buenos usos
- 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.
Códigos HTTP
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 es un éxito?
Significa que el endpoint aceptó una petición bien formada. En Bing/global la clave puede validarse después; un archivo malo puede descartar el lote en silencio. Comprueba la clave primero.
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 garantiza indexación o rankings?
No. Solo notifica cambios. La indexación depende de cada motor.
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.
