what is indexnow and why does it matter for ai search?
IndexNow is a free protocol that instantly notifies Bing, Yandex, Naver, and Seznam when a URL is created or updated, cutting indexing time from days to minutes. Since ChatGPT search, Copilot, and DuckDuckGo AI chat all retrieve from Bing, fast Bing indexing directly accelerates AI citation eligibility. Generate a key, host it at your domain root, and push URLs via the IndexNow API on publish. Most CMS platforms including WordPress, Shopify, and Webflow now support IndexNow natively.
Evidence and detail
- IndexNow was launched by Microsoft and Yandex in October 2021 and is now adopted by Cloudflare and Wix.
- Bing indexes IndexNow-submitted URLs within roughly 10 minutes versus 3 to 7 days for sitemap-only flow.
- Cloudflare offers a one-click IndexNow integration that automatically pings Bing on cache purge and origin updates.
- Faster Bing indexing means ChatGPT search citations are eligible within hours of publish, not days.
