IndexNow for AI Search: How to Get Indexed Faster in ChatGPT, Copilot, and Bing

IndexNow is a free protocol that lets you instantly notify Bing (and other search engines) when you publish, update, or delete web pages. Because Bing powers ChatGPT Search and Microsoft Copilot, faster Bing indexing means faster visibility in AI search results—often within hours instead of days.

What is IndexNow and why does it matter for AI search?

IndexNow is a submission API developed by Microsoft, Yandex, and Naver. Instead of waiting for search engine crawlers to discover your content changes, you push notifications directly to Bing's index. Bing then crawls your updated pages on priority, and that freshly indexed content flows into ChatGPT Search and Copilot's retrieval systems.

The practical win: new articles, product updates, and corrected information reach AI search engines faster—sometimes within 24 hours instead of the typical 3–7 day crawl cycle.

How does IndexNow feed ChatGPT Search and Copilot?

Bing is the indexing backbone for both ChatGPT Search (OpenAI's real-time search feature) and Microsoft Copilot. When you submit a URL via IndexNow, Bing prioritizes crawling it. That indexed content then becomes available to ChatGPT Search and Copilot when users ask related questions.

This is different from Google's indexing pipeline: Google AI Overviews pull from Google's own index, while ChatGPT and Copilot rely on Bing's. If you want fast AI search visibility across OpenAI and Microsoft's products, IndexNow is a direct lever.

How do you implement IndexNow?

Step 1: Generate an API key

• Go to bing.com/indexnow
• Click "Generate key" and save it as a .txt file
• Upload it to your site's root directory (e.g., yoursite.com/your-api-key.txt)
• Verify ownership by visiting yoursite.com/indexnow?url=yoursite.com&key=your-api-key

Step 2: Submit URLs

You can submit URLs three ways:

1. Manual submission: Use Bing's web form to paste individual URLs
2. API calls: POST requests with your key and URL list (best for automation)
3. CMS plugins: WordPress, Shopify, and other platforms have IndexNow plugins that auto-submit on publish

Step 3: Automate for ongoing updates

For high-traffic sites, use a plugin or custom script to auto-submit URLs when you publish or update content. This ensures Bing stays in sync with your site.

Step 4: Monitor indexing speed

Use Bing Webmaster Tools to check crawl rates and indexing status. Note: you can't directly measure ChatGPT Search visibility in real time, but faster Bing indexing is a prerequisite.

What's the difference between IndexNow and XML sitemaps?

XML sitemaps are passive—they sit on your site waiting for crawlers to find them. IndexNow is active: you push notifications immediately. Sitemaps are still useful for discovery and priority hints, but IndexNow is faster for time-sensitive content.

Best practice: use both. Submit your sitemap to Bing Webmaster Tools and implement IndexNow for critical updates.

How do you measure IndexNow's impact on AI search visibility?

Bing Webmaster Tools shows crawl frequency and index coverage, but that doesn't directly show ChatGPT Search or Copilot mentions. To measure actual AI search visibility, you need to:

• Sample queries related to your content across ChatGPT Search, Copilot, and Perplexity
• Track whether your brand or content appears in results
• Run multiple queries over time to establish a baseline and confidence level

Tools like Orem track this systematically—running repeated samples with 95% confidence intervals to separate real visibility gains from statistical noise. This matters because AI search results are less standardized than Google's, and single queries can be misleading.

Frequently asked questions

Does IndexNow guarantee faster indexing in ChatGPT Search?

IndexNow guarantees faster crawling by Bing, which feeds ChatGPT Search. However, OpenAI's ranking algorithm may still deprioritize your content. IndexNow solves the indexing problem, not the ranking problem.

Is IndexNow free?

Yes. There are no fees or usage limits.

Can I use IndexNow with Google?

Google doesn't support IndexNow. Use Google Search Console's URL Inspection tool and XML sitemaps instead.

How often should I submit URLs?

Submit only when content changes. Submitting the same URL repeatedly wastes resources and may trigger rate limits.
