How to block or allow Bingbot in robots.txt
Bingbot follows robots.txt and, unlike Googlebot, honors Crawl-delay.
Block Bingbot
User-agent: Bingbot Disallow: /
Allow Bingbot
User-agent: Bingbot Allow: /
Put the rules in /robots.txt at the root of each host. Check the result with our AI Crawler Checker, which also catches firewall and CDN blocks that robots.txt doesn't show.
Should you block Bingbot?
Allow it. Blocking Bingbot removes you from Bing and from the AI products built on Bing's index.
How to verify real Bingbot traffic
Reverse DNS on the IP should end in search.msn.com, and a forward lookup should return the same IP. Or match it against Microsoft's published list. Bing Webmaster Tools also has a Verify Bingbot tool.

Frequently asked questions
What is Bingbot?
Bingbot is Microsoft Bing's crawler. Bing's index also powers Microsoft Copilot answers and is used by other search products, so Bingbot access matters beyond Bing itself.
How do I block Bingbot?
Add "User-agent: Bingbot" followed by "Disallow: /" to your robots.txt. To block only part of the site, disallow those paths instead of "/". Bingbot follows robots.txt and, unlike Googlebot, honors Crawl-delay.
Is a request claiming to be Bingbot really from Microsoft?
Not necessarily: anyone can copy a user agent. Reverse DNS on the IP should end in search.msn.com, and a forward lookup should return the same IP. Or match it against Microsoft's published list. Bing Webmaster Tools also has a Verify Bingbot tool.
Checked against Microsoft's documentation on 2026-11-06. Vendors change user agents and policies, so confirm in the official docs before relying on them.
