What is IndexNow? A clear guide for SEOs
Last updated: June 10, 2026. About 7 min read
IndexNow is an open protocol that lets websites notify participating search engines when URLs are added, updated, or deleted, so crawlers can learn about changes sooner instead of waiting for a routine crawl.
If you publish often or run a large site, IndexNow reduces the lag between “we shipped it” and “engines know it exists.” It is not magic ranking juice. It is a discovery signal.
Which search engines support IndexNow?
Support has included (among others):
- Microsoft Bing
- Yandex
- Seznam.cz
- Naver
- Additional partners that adopt the shared endpoint model
When you ping one supporting endpoint correctly, other participants can receive the same URL change notification. Always check current official documentation for the latest participant list.
How IndexNow works
- You generate an API key and host a key file on your domain.
- When content changes, you send an HTTP request with the key and one or more URLs.
- Participating engines receive the notification and may prioritize crawling those URLs.
Engines still choose whether and when to crawl or index. IndexNow improves the odds of timely discovery; it does not guarantee inclusion.
Simple request example
POST https://api.indexnow.org/indexnow
Content-Type: application/json
{
"host": "www.example.com",
"key": "your-indexnow-key",
"keyLocation": "https://www.example.com/your-indexnow-key.txt",
"urlList": [
"https://www.example.com/new-page",
"https://www.example.com/updated-guide"
]
}Exact endpoints and payload fields can vary slightly by implementation. Validate against the official IndexNow specification before production use.
Benefits of IndexNow
- Faster change awareness for Bing and other participants
- Efficient for large sites that update thousands of URLs
- Works well with automation (CMS hooks, deploy pipelines, indexing APIs)
- Complements sitemaps rather than replacing them
Limitations (including Google)
Google does not fully support IndexNow as a primary submission channel the way Bing does. For Google, you still rely on:
- Crawlable architecture and internal links
- XML sitemaps
- Google Search Console URL Inspection / sitemap reports
- Overall site quality and demand
Other limits: over-notifying low-value URLs wastes crawl attention; key misconfiguration fails silently; and notifications never override spam or quality filters.
How BestIndexingTool uses IndexNow
BestIndexingTool includes IndexNow support as part of a broader indexing tool feature set. When you submit URLs or backlinks, we can notify IndexNow-compatible engines and combine that with status tracking and reports so you see what was queued, not just hope a ping worked.
For Google-oriented workflows, pair our tool with solid GSC hygiene. Read how to index a website on Google for the full playbook, and compare options in our best backlink indexer 2026 guide.
Should you implement IndexNow yourself or use a tool?
- DIY: Best if you have engineering time and a single large property
- Managed tool: Best for agencies juggling many domains, backlinks, and client reports
