Should You Block Bingbot?

Caution: Bingbot is a search engine crawler. Blocking it will remove your pages from Microsoft's search index, which directly impacts your organic traffic and visibility.

Only block Bingbot if you intentionally want to de-index your site from Microsoft. Instead, consider using Switch to serve optimized content or manage specific page access.

Blocking Methods

1robots.txt

High for cooperative crawlers

Add a Disallow rule for Bingbot's user-agent string in your robots.txt file. This is the standard, cooperative method that well-behaved crawlers respect.

2Server-side UA filtering

High

Configure your web server (nginx, Apache, Cloudflare) to reject requests matching Bingbot's user-agent patterns. This blocks at the network level before your application processes the request.

3Switch Journey Workflows

Highest — granular, real-time control

Create a custom journey in Switch that detects Bingbot and routes it to a block action, challenge, redirect, or modified content — without touching your server configuration.

robots.txt — Block Bingbot

Add the following to your robots.txt file (at the root of your domain) to block Bingbot:

User-agent: bingbot
Disallow: /

User-agent: Bingbot
Disallow: /

User-agent: msnbot
Disallow: /

robots.txt — Allow with Restrictions

Alternatively, allow Bingbot on most pages while blocking specific directories:

User-agent: bingbot
Disallow: /private/
Allow: /

User-agent: Bingbot
Disallow: /private/
Allow: /

User-agent: msnbot
Disallow: /private/
Allow: /

Bingbot User-Agent Strings

Use these patterns to identify Bingbot in your server logs or firewall rules:

bingbot
Bingbot
msnbot

Frequently Asked Questions

Does blocking Bingbot affect my Google search rankings?

No. Blocking Bingbot does not affect your Google search rankings. Only blocking Googlebot impacts Google Search visibility.

Does Bingbot respect robots.txt?

Yes, Bingbot respects robots.txt directives. Adding a Disallow rule for its user-agent will prevent it from crawling blocked paths.

Can I allow Bingbot on some pages but not others?

Yes. Use robots.txt to disallow specific directories, or use Switch journey workflows for granular page-level control with conditional logic.

Go beyond robots.txt

Switch detects Bingbot in real-time and lets you build custom journey workflows — block, challenge, redirect, or serve modified content. No server changes required.
