IndexNow is an open protocol jointly initiated by Microsoft Bing and Yandex that allows site owners to proactively inform search engines via a single HTTP request that the content of a URL has been added, updated, or deleted.
The IndexNow protocol itself does not specify how to determine content changes; it only receives a URL and a verification key, and the determination logic is entirely implemented on the site owner's side.
On October 8, 2026, NeuraGrowth shipped the change of switching IndexNow to hashing crawler-readable content.
The author uses IndexNow to ping Bing and Yandex on every push via a GitHub Action, automatically submitting a sitemap of 814+ URLs.
