Reported, not operator documented
Microsoft has not published a crawler page that names AzureAI-SearchBot. It is listed here because a credible public source does: ai.robots.txt. Reported Azure AI Search crawler token. Microsoft publishes no page for it.
What that means for you: the robots.txt rule on this page is the best available spelling, and a well-behaved crawler using this string will honour it, but there is no vendor statement of purpose, crawl rate or robots.txt compliance to rely on. Treat a matching request in your logs as a detection clue, not proof of who sent it, and combine the rule with a firewall rule if the traffic matters to you. If the operator publishes documentation, this profile moves to Official docs.
What is Azure AI Search?
Azure AI Search is an AI search-index crawler operated by Microsoft. It collects and indexes web content so it can be surfaced as citations or answers inside Microsoft's AI search experience. Allowing Azure AI Search can increase your visibility in AI-powered search results, which is why most sites choose to permit it.

Allowing Azure AI Search can increase your visibility in AI-powered search results, which is why most sites choose to permit it.
Azure AI Search uses the user-agent token AzureAI-SearchBot. You can control it via robots.txt, meta tags (noai), or the emerging llms.txt standard. Robots.txt is voluntary; for hard enforcement, combine it with server-level IP blocking.
What happens if you block Azure AI Search?
User-agent / Disallow: / without any SEO penalty.AzureAI-SearchBot compared with documented Microsoft crawlers
| Token | Documented by Microsoft? | What it is linked to | Effect of blocking |
|---|---|---|---|
| AzureAI-SearchBot | No (Reported) | Reported with Azure AI search services | Unknown; may stop an Azure-based indexer |
| bingbot | Yes | Bing Search and Copilot grounding | Removes you from Bing and Copilot answers |
| BingPreview | Yes | Page previews in Bing | Previews missing |
| OAI-SearchBot | Yes (OpenAI) | ChatGPT search, often confused with Microsoft | Drop out of ChatGPT search |
Microsoft's crawl-to-refer ratio was 40.7 pages per visitor in Cloudflare, 29 August 2025 data, far better than most AI-first operators, which is why Bingbot should almost never be blocked.
AzureAI-SearchBot use cases
| If you are... | Recommended setting and why |
|---|---|
| You want Copilot visibility | Keep Bingbot allowed. That is the documented route into Copilot. |
| You see AzureAI-SearchBot in logs | Treat it as an Azure-hosted indexer of unknown owner. Check reverse DNS; an Azure IP proves the host, not the operator. |
| You block unverified bots | A named Disallow group is safe; it has no documented search effect. |

Frequently Asked Questions
What user-agent string does Azure AI Search use?
AzureAI-SearchBot. That spelling comes from ai.robots.txt, not from Microsoft, which has not published crawler documentation naming it. Use it in robots.txt as the best available match, and treat a request carrying it as a clue rather than proof of who sent it.Is Azure AI Search safe?

User-agent / Disallow: / without any SEO penalty.How do I block Azure AI Search in robots.txt?
/robots.txt file:User-agent: AzureAI-SearchBot Disallow: /
