The Index Behind AI Search
ChatGPT's browsing feature, Microsoft Copilot, and several other AI search tools rely on Bing's index per their public documentation (OpenAI / ChatGPT search announcement). This means your Bing indexing status directly determines whether those AI engines can find and cite your content. Google's Gemini app uses Google's index; Perplexity has its own crawler in addition to leveraging third-party indexes.
If you have been ignoring Bing Webmaster Tools (and most people have), you may be invisible to several major AI search engines.
What to Do Right Now
- Go to bing.com/webmasters and sign up (it is free)
- Verify your domain using DNS, meta tag, or CNAME
- Submit your XML sitemap
- Check your indexing status — how many of your pages does Bing actually know about?
- Review any crawl errors or blocked pages
Common Issues We See
When we audit SaaS websites for AI visibility, the most common Bing-related issues are:
- robots.txt blocking Bing's crawler (Bingbot) but allowing Googlebot
- Pages indexed by Google but missing from Bing's index
- Sitemap not submitted to Bing (many tools only auto-submit to Google)
- Slow crawl rate because Bing has not been told the site is important
Bing-Specific Optimization Tips
Bing's documentation describes some different ranking signals than Google ('s Search Central documentation. For AI visibility specifically, focus on: clear meta descriptions, valid schema.org markup (schema.org is canonical), and exact-match content. Bing's webmaster guidelines spell these out in detail.
