What is the IndexNow Protocol?
IndexNow is an open-source URL submission protocol that allows website owners to notify participating search engines immediately when pages are published, updated, or deleted, rather than waiting for those engines to discover changes through their regular crawl schedules. A single IndexNow notification can be processed by all participating search engines simultaneously. The protocol works by: verifying domain ownership via a key file, then sending HTTP POST requests with URLs to the IndexNow API endpoint whenever content changes.
IndexNow for SaaS Programmatic Content
IndexNow is especially valuable for SaaS companies deploying large volumes of new content at once: a programmatic SEO deployment of 500 new integration pages, submitted via IndexNow immediately after creation, will be crawled by Bing within hours versus potentially weeks through regular discovery. For WordPress sites, Rank Math and Yoast SEO plugins support automatic IndexNow submission on publish. For custom implementations: use the IndexNow API to send batch URL submissions of up to 10,000 URLs per request.
Frequently Asked Questions
Which search engines support IndexNow?
As of 2026: Microsoft Bing, Yandex, Seznam.cz, Naver, and several smaller search engines support the IndexNow protocol. Google does not officially support IndexNow, maintaining its own crawl scheduling systems. However, Microsoft reports IndexNow notifications are shared with other participating engines. For Google indexing acceleration: continue using XML sitemap submission and URL Inspection request indexing for priority individual pages, while using IndexNow for broad coverage of all new content with Bing and other participating engines.
How do I implement IndexNow on a WordPress site?
Easiest implementation: install Rank Math SEO or Yoast SEO and enable IndexNow in plugin settings. The plugin generates your verification key file, places it at the domain root, and automatically submits new and updated posts to IndexNow on publish. Manual implementation: generate a random API key, place a key file at yourdomain.com/your-key.txt, then POST to https://api.indexnow.org/indexnow with your key and the URLs to submit as JSON payload. Verify the implementation is working by checking Bing Webmaster Tools for IndexNow submission history and monitoring time-to-index for newly submitted pages.
