IndexNow is a free, ouvrir push protocol from Microsoft Bing and Yandex (launched Oct 18, 2021; aussi Seznam, Naver, and Yep): vous ping participating engines the instant une URL is ajouté, mis à jour, or deleted, and un submission is shared à travers tout of les. Setup is a clé fichier at votre root plus a simple HTTP OBTENIR (un URL) or POST (up to 10 000). It speeds up discovery and recrawl — it doesn't guarantee indexation and it's pas a ranking lever. Google ne fait pas utiliser IndexNow: it said it voudrait tester the protocol in 2021 and jamais adopted it, so it ne fait pashing pour Google. Garder votre sitemaps; IndexNow is additive, and the Google Indexation API is a separate, narrow outil.

TL;DR — IndexNow is an ouvrir push protocol (Microsoft Bing + Yandex, launched Oct 18, 2021; joined by Seznam, Naver, and Yep). Vous host a {key}.txt fichier at votre root pour verification, alors notify engines on ajouter/mettre à jour/delete via a OBTENIR (un URL) or a JSON POST (≤10 000 URLs). The differentiator is the shared ping — submit une fois, reach every participant. It accelerates discovery and recrawl prioritization; it fait pas guarantee indexation and is pas a ranking signal. Google ne fait pas utiliser IndexNow — it said in Nov 2021 it voudrait “be testing” the protocol and jamais adopted it, so it ne fait pashing pour Google. Garder votre sitemaps; the Google Indexation API is a separate, narrow outil.

Ce que IndexNow en réalité is

IndexNow is the push side of URL discovery. La plupart discovery is pull — engines follow liens and lire votre sitemap on leur propre schedule. IndexNow lets vous proactively tell participating engines que something modifié so ils peut prioritize the (re)explorer. Bing’s propre framing: “Si you’re ajout, updating, or deleting content, IndexNow notifies multiple moteur de recherches of votre content changements as soon as ils se produire.”

It was launched October 18, 2021 by Microsoft Bing and Yandex, and it’s a free, ouvrir protocol — “a free, open-source protocol empowering website owners with unprecedented contrôler over how quickly leur content is découvert,” in Bing’s words. The protocol spec lives at indexnow.org.

Who participates (and who doesn’t)

Participating engines today: Bing, Yandex, Naver, Seznam.cz, and Yep (Ahrefs’ moteur de recherche) — that’s the liste indexnow.org’s homepage credits as offering prise en charge. Parce que Bing powers a chunk of the AI-search ecosystem, feeding Bing’s index via IndexNow peut aussi aider visibility on Copilot, ChatGPT Search, and DuckDuckGo.

As of my July 2026 vérifier, indexnow.org’s FAQ aussi listes a submission endpoint pour Amazon (indexnow.amazonbot.amazon) alongside Bing, Naver, Seznam.cz, and Yandex — but the homepage’s propre “support from” line hasn’t been mis à jour to inclure it. I’d treat Amazon’s participation as newly emerging plutôt que entièrement confirmed jusqu’à le site is internally consistent à propos de it.

Participating aussi isn’t a promise to explorer or index ce que vous send: indexnow.org’s propre spec is explicit que engines “agree que submitted URLs va be automatically shared” with every autre participant — sharing the ping, pas committing to act on it.

Google n’est pas on que liste. Plus on que ci-dessous — it’s the unique la plupart misunderstood chose à propos de ce protocol.

Comment cela fonctionne

Là are four moving parts: a clé, a clé fichier, the submission, and the shared ping.

1. Generate a clé

A clé is a hexadecimal string (the spec permet 8–128 characters: a–z, A–Z, 0–9, and dashes). It’s ce que ties votre submissions to votre domain. Bing: “An API key is needed to match the ownership of the domain with submitted URLs.”

2. Host the clé fichier (verification)

Placer a UTF-8 text fichier named {your-key}.txt, containing the clé, at votre site root (or un autre emplacement vous declare via keyLocation). Engines récupérer it to confirmer vous contrôler the host avant ils accept anything. Bing: “Host votre UTF-8 clé fichier at the root of votre website.” The indexnow.org spec: the clé fichier is how “moteur de recherches utiliser ce fichier to confirmer domain ownership avant accepting IndexNow submissions.” Ce is the whole authentication model — there’s aucun OAuth, aucun service account, simplement a fichier vous pouvez serve.

Si vous utiliser a non-root keyLocation, its chemin aussi scopes qui URLs que clé peut cover — ce is a detail personnes miss. Per the indexnow.org spec: “the emplacement of a clé fichier determines the définir of URLs que peut be inclus with ce clé.” A clé fichier at example.com/catalog/key.txt peut submit URLs sous /catalog/ but pas sous /help/. Root placement avoids ce limite entirely, qui is pourquoi the spec calls it the “strongly recommended” option.

3. Submit URLs — OBTENIR (unique) or POST (bulk)

Pour un URL, a plain HTTP OBTENIR is suffisant:

https://api.indexnow.org/indexnow?url={url-changed}&key={your-key}

Pour nombreux URLs, a unique JSON POST carries up to 10 000 of les (“IndexNow supports bulk submission of up to 10,000 URLs per POST request.”):

{
  "host": "www.example.org",
  "key": "your-key",
  "keyLocation": "https://www.example.org/your-key.txt",
  "urlList": [
    "https://www.example.org/url1",
    "https://www.example.org/folder/url2"
  ]
}

Au-delà the 10 000-per-POST cap, indexnow.org doesn’t publish a fixed daily URL quota — its FAQ dit plainly que it “ne fait pas publicly disclose exact rate limites, as chaque participating moteur de recherche sets its propre daily submission thresholds per site.” En pratique, the seulement quota signal you’ll voir is a 429 réponse, pas a documented number to plan autour.

The protocol’s documented réponse codes are worth knowing quand you’re debugging: 200 OK (submitted successfully), 202 Accepted (reçu, but — per indexnow.org’s spec — “IndexNow key validation pending”, qui the FAQ dit typically montre up seulement on votre premier submission with a nouveau clé, avant subsequent requêtes settle back to 200), 400 (bad requête / invalid format), 403 Forbidden (clé pas valid, or the fichier is trouvé but the clé isn’t in it), 422 (URLs don’t belong to the host, or the clé schema doesn’t match), and 429 (aussi nombreux requêtes — treated as potential spam). Bing’s propre get-started page listes the même définir minus 202.

4. The shared ping — submit une fois, reach every participant

Ce is the fonctionnalité que rend IndexNow worth the trouble. From the spec: “Chaque endpoint sends votre submission directement to its respective moteur de recherche, and votre submission va be shared à travers tout IndexNow-enabled moteur de recherches.” Vous peut hit the global endpoint, api.indexnow.org, or quelconque participant’s endpoint (Bing’s, Yandex’s, etc.) — the effect is the même. Un submission propagates to tout of les. Vous don’t maintain a separate integration per engine.

Fait Google utiliser IndexNow?

Aucun. Ce is the partie la plupart pages on the web obtenir incorrect or leave vague, so I vouloir to be exact à propos de it.

Google’s seulement substantive public statement came in November 2021, to Search Engine Land. A Google spokesperson said: “We’re encouraged by fonctionner to faire web exploration plus efficient, and we va be testing the potential benefits of ce protocol.” Remarque the framing — it’s à propos de explorer efficiency and testing, pas a commitment to adopt. Moteur de recherche Journal reported the même statement the même day sous a “will be testing” headline.

Années plus tard, nothing has modifié. Google jamais adopted IndexNow. Yoast, who construire an official IndexNow-capable plugin, put Google’s stance plainly: “Google n’est pas currently participating in ce initiative, citing its very efficient exploration mechanism and its continued improvement.” Wikipedia’s entry likewise notes que as of 2022 Google had pas officially adopted the protocol — and it encore hasn’t.

So: submitting to IndexNow ne fait pashing pour Google indexation or rankings. Don’t conflate ce with Google’s separate crawl-efficiency fonctionner (Gary Illyes’ “explorer moins” push) — that’s à propos de Google exploration its propre façon plus efficiently, pas à propos de adopting IndexNow as the mechanism. Pour Google, votre discovery channels remain liens, sitemaps (with accurate lastmod), RSS/feeds, and WebSub — the push and pull mechanisms I walk via on my How Search Fonctionne deck. IndexNow simply isn’t un of les.

IndexNow vs sitemaps vs the Google Indexation API

Personnes reach pour IndexNow expecting it to replace something. It doesn’t. Ces are three différent outils with three différent jobs:

IndexNowXML SitemapsGoogle Indexation API
ModelPush (notify on modifier)Pull (engines explorer on schedule)Push (notify Google)
EnginesBing, Yandex, Naver, Seznam, Yep (shared)Tout engines, incl. GoogleGoogle seulement
Content scopeTout content typesTout content typesSeulement JobPosting + BroadcastEvent (livestream)
SpeedNear-instant on participantsDays to weeks to be découvertNear-instant pour eligible content

SetupClé fichier at root + HTTPXML fichier referenced in robots.txt / GSCCloud project + service account
Google effectNoneYesYes — but seulement the two allowed schema types

The takeaways I’d vouloir vous to leave with:

  • They’re complementary, pas substitutes. Garder votre sitemaps — that’s how Google and everyone sinon discovers vous at scale. Utiliser IndexNow to accelerate discovery on Bing/Yandex/Naver/Seznam/Yep.
  • The Google Indexation API n’est pas “Google’s IndexNow.” It’s officially limited to job postings and livestream video — “Google’s Indexation API officially seulement supports two content types,” as CrawlWP puts it. The “instant indexation” plugins que fire it at ordinary pages are off-policy.
  • Pour Google, là is aucun public push API pour ordinary pages. Sitemaps plus bon explorer health is the chemin.

Benefits and limites

The efficiency story is the honest pitch. The canonical justification is Cloudflare’s observation que “53% of this crawler traffic is wasted” — engines re-crawling pages que didn’t modifier. IndexNow attacks exactly que waste by telling engines quand to come back au lieu de making les guess. Bing frames the upside as helping “drive plus relevant trafic to votre site, améliorer search engine rankings, and lower explorer costs,” and in 2025 décrit IndexNow as “becoming foundational to the way search engines keep pace with web changes.”

Où it genuinely helps:

  • Fast-changing or time-sensitive content — news, ecommerce inventory and pricing, press releases, anything où minutes matter on Bing.
  • Bing-fed AI surfaces — Copilot, ChatGPT Search, DuckDuckGo tout lean on Bing’s index.

Où it doesn’t:

  • Google — zero effect, complet arrêter.
  • Rankings — it speeds discovery, pas position. Faster exploration ≠ plus élevé ranking.
  • Guaranteed indexation — it’s a prioritization signal; the engine encore decides si and quand to index.

Adoption has grown fast — Bing reported “plus que 16 million web sites… publishing over 1,2 billion URLs per day” in August 2022, and “3,5 billion URLs submitted per day” by December 2024, with adopters notamment Shopify, GoDaddy, the Internet Archive, and Condé Nast. (Quelconque plus grand 2026 figures vous voir floating autour are secondary-sourced; I’d treat les as estimates jusqu’à Bing publishes a fresh number.)

How to définir it up (vous probably won’t écrire code)

La plupart personnes jamais touch the raw API — a platform fait it pour vous:

  • Cloudflare — un click. Enable Robot d’exploration Hints (Cache → Configuration) and “Cloudflare va prendre care of signaling to ces moteur de recherches quand votre content has modifié via the IndexNow protocol.” Ce was the premier big one-click integration, shipped on launch day.
  • WordPress — Yoast SEO Premium (it “va ping IndexNow whenever vous publish or mettre à jour votre content”), Rank Math, Tout in Un SEO, or Microsoft’s official IndexNow plugin.
  • Wix, Duda, Shopify — built-in prise en charge.
  • Bing Webmaster Outils — manual URL submission tied to IndexNow, plus the IndexNow Insights report.
  • Ahrefs Site Audit — the integration I construit (voir the Outils tab). Generate a clé in the explorer config, drop it in the clé fichier, and submit lune pages Site Audit flags as modifié, redirigé, or supprimé.

Si vous are rolling votre propre, voir the Scripts tab pour the réel OBTENIR and POST calls and the key-file setup.

Courant myths

  • “IndexNow gets you indexed in Google / boosts Google rankings.” Faux. Google doesn’t consume IndexNow.
  • “Faster indexing means higher rankings.” Faux. IndexNow speeds discovery; ranking encore dépend on the usual factors.
  • “Google is about to adopt it.” Non pris en charge. It testé it in 2021 and jamais adopted it; its plus tard crawl-efficiency fonctionner is unrelated.
  • “IndexNow replaces sitemaps.” Faux. Sitemaps remain essential, surtout pour Google. IndexNow is additive.
  • “The Indexing API is Google’s IndexNow for any page.” Faux — JobPosting + BroadcastEvent seulement.
  • “It guarantees indexing.” Faux. It’s a prioritization signal.

Où ce sits in the bigger picture

IndexNow is the cross-engine push analog of the feed mechanisms Google uses (RSS, WebSub) — même idea (“tell me what changed”), différent participants. It lives in the getting-pages-discovered-faster corner of exploration, alongside the Google Indexation API.
