IndexNow: instant indexing for Bing and Yandex (but not Google)

IndexNow is a one-line ping that tells several search engines the instant your content changes, instead of waiting for them to crawl you. It is genuinely useful, with one catch that most guides bury until the end: Google is not one of the engines that uses it. IndexNow reaches Bing, Yandex, Naver and Seznam; Google has tested it since 2021 and never adopted it. So this guide covers what IndexNow does, who actually listens, and how to handle Google separately, because for Google you need a different path entirely.

01 · The definitionWhat IndexNow is

The old model is pull: search engines crawl the web on their own schedule, and your new page waits, invisible, until a crawler happens by. IndexNow flips that to push: the moment you publish, you send the URL to the engines, and they come fetch it. For time-sensitive pages, a changelog, a price update, a new post, that turns a wait of days into near-instant crawling. On the engines that support it.

02 · The engine listWho actually listens (and who doesn't)

This is the part to get straight before you invest any effort.

Google’s absence is the whole catch. It runs its own crawl infrastructure and has never joined IndexNow, so a ping does nothing for your Google ranking or indexing timeline. Any tool that markets IndexNow as a way to “instantly index on Google” is misrepresenting it. What IndexNow genuinely does is speed up Bing and the others, which still matters: they send real traffic, and some of them increasingly act as the live index behind AI answer tools.

03 · The two-minute versionHow to set it up

IndexNow is deliberately simple. You prove you own the domain with a key file, then submit URLs.

First, host a key file at your root. The filename is the key, and its only contents are the key itself:

<your-key>

Then notify the engines when something changes by sending the URL to an IndexNow endpoint. One call reaches all participating engines:

curl "https://api.indexnow.org/indexnow?url=https://pagewatch.dev/changelog&key=<your-key>"

In practice you rarely do this by hand. Cloudflare can fire IndexNow for you at the edge, and WordPress plugins like Yoast and Rank Math, and platforms like Shopify, offer native integrations that ping automatically whenever you publish. Set it once and forget it.

04 · The honest scopeWhat it does and does not promise

IndexNow removes the discovery delay on participating engines, and nothing more. It tells those engines a URL is worth crawling now; it does not force them to index it. They still apply their own quality filters, so a thin, blocked, or low-value page can be fetched and then skipped. It is “come look now,” not “add this to your index.”

So the honest summary: ship IndexNow because it is cheap, often automated for you, and a real speed-up on Bing and friends, not because it touches Google. In the bigger picture it is a small, worthwhile piece of the discovery floor, sitting alongside your sitemap and a clean robots.txt. It is plumbing for the engines that use it, not a shortcut past the work of becoming worth indexing.
