IndexNow

IndexNow is a protocol that lets a site instantly notify participating search engines (notably Bing and Yandex) when a URL is added, updated, or removed.

Instead of waiting for a crawler to find a change, you push a ping and the engine fetches it quickly.

Why it matters: Bing crawls small sites slowly, so IndexNow is the fastest route into Bing's index — and therefore into ChatGPT's pool of citable pages.
