IndexNow
IndexNow is an open protocol that lets a website instantly notify participating search engines when pages are added, updated, or deleted, instead of waiting for crawlers to rediscover them. Supported by Microsoft Bing and Yandex among others, it uses a simple API call with a verification key to push URL change notifications.
Key Takeaways
- IndexNow is an open protocol that lets a website instantly notify participating search engines when pages are added, updated, or deleted.
- It is supported by Microsoft Bing and Yandex among others, using a simple API call with a verification key.
- It replaces waiting for crawlers to rediscover changes, so new content can become eligible for search and AI answers sooner.
- It is most valuable for sites that publish or change pages frequently.
- Pinging for trivial or low-value changes wastes effort and can dilute the signal, so notifications should be reserved for meaningful updates.
How It Works
IndexNow works by letting a site push a notification the moment a URL changes, rather than waiting passively for a crawler to return. You host a verification key file on your domain, then send a simple API request listing the changed URLs to a participating endpoint. Engines that support the protocol, including Bing and Yandex, share submissions with each other, so one ping reaches multiple engines.
Faster awareness helps content compete sooner in both traditional search and AI answers, which connects it to Answer Engine Optimization, where being crawled and understood quickly matters. It pairs well with an editorial signal file like llms.txt that points engines to your best content.
Used wisely, IndexNow helps counter Content Decay by getting refreshed pages re-evaluated fast, and it supports Entity SEO by keeping the entities on updated pages current. The discipline is restraint: ping meaningful changes, not every minor edit.
Why It Matters
Faster indexing means new and updated content becomes eligible for search and AI answers sooner. For sites that publish or change pages frequently, IndexNow reduces the lag between shipping content and having engines aware of it.
Example
A news-style site publishes several articles a day. It wires IndexNow into its publishing workflow so that each time an editor hits publish or updates a story, the CMS automatically sends the URL to the IndexNow endpoint. New pieces appear in Bing noticeably sooner than when the site relied on crawlers alone, shortening the gap between shipping and being discoverable.
Common Mistake
Pinging IndexNow for every trivial change or for low-value pages. Flooding the endpoint wastes effort and can dilute the signal. Reserve notifications for meaningful additions and updates.
Frequently Asked Questions
Which search engines support IndexNow?
Microsoft Bing and Yandex are core supporters, and several other engines and platforms participate. Because participating engines share submissions with each other, notifying one supported endpoint effectively informs the others in the network.
Does IndexNow work with Google?
Google has run tests but does not treat IndexNow as a primary submission method the way Bing does. For Google, rely on internal linking, sitemaps, and Search Console. IndexNow still delivers clear value for Bing and its partners.
How do I set up IndexNow?
Generate a key, host a text file containing that key on your domain, then send an API request listing changed URLs to a participating endpoint. Many CMS platforms and plugins automate the submission step once the key is in place.
Will IndexNow improve my rankings?
No. IndexNow speeds up discovery of changes; it does not boost rankings directly. Faster indexing means content becomes eligible sooner, but relevance, quality, and links still determine where it ranks once indexed.
