# Bingbot [Search Engine Crawler](/content/ai-agent-directory?tags=Search%20Engine%20Crawler/index.html) Microsoft Bing web crawler for search indexing. Overall rank #2 of 51 ▲2 m/m Category rank #2 of 11 ## What does Bingbot do? `Bingbot` crawls the web to discover and refresh pages for Bing's search index. Crawled content feeds Bing Search results, Bing Chat, [Microsoft](https://microsoft.com/) Copilot, and other AI-powered answer features across [Microsoft](https://microsoft.com/)'s ecosystem. Bing Search drives direct referral traffic through clickable links in standard results, and Bing's AI features often include source citations that link back to your site. ## Should I allow and optimize for Bingbot to drive organic growth? `Bingbot` is the gateway to Bing Search, which serves hundreds of millions of queries per day. Allowing it is essential for appearing in Bing results, Bing Chat, and [Microsoft](https://microsoft.com/) Copilot responses. All of these surfaces drive direct referral traffic through clickable links and source citations. Bing also powers search results in [DuckDuckGo](https://duckduckgo.com/), [Yahoo](https://yahoo.com/) (in some markets), and other partners, amplifying your reach beyond bing.com itself. Blocking `Bingbot` removes your site from all of these channels. Here's how to optimize for Bingbot: - Allow Bingbot in your robots.txt and submit your sitemap through Bing Webmaster Tools - Use semantic HTML and structured data (JSON-LD) to help Bing understand your content - Ensure pages load quickly and render critical content server-side when possible - Add descriptive title tags and meta descriptions to improve snippet quality in search results - Use IndexNow (supported natively by Bing) to notify Bing instantly when you publish or update content - Set appropriate meta robots directives (nocache, noarchive) if you want to control AI training use without blocking indexing - Verify your site in Bing Webmaster Tools to access crawl stats, URL inspection, and crawl rate controls ## Data Usage & Training Content crawled by `Bingbot` may be used to train [Microsoft](https://microsoft.com/)'s generative AI foundation models. Pages without NOCACHE or NOARCHIVE meta tags can appear in Bing Chat answers and feed into training data. You can limit this: adding a NOCACHE meta tag restricts training use to URL, title, and snippet only. Adding NOARCHIVE prevents your content from being used for training entirely. ## How Bingbot Accesses Content Here's how Bingbot accesses your site and understands your content: - Fetches HTML via standard HTTP requests using a well-known user-agent string - Fully renders JavaScript (uses a Chrome-like UA variant for JS rendering) - Follows links to discover new pages and re-crawls known pages for freshness - Processes sitemaps declared in robots.txt - Respects robots.txt Disallow, Allow, Crawl-delay, and Sitemap directives - Supports meta robots tags, X-Robots-Tag headers, and Bing-specific directives via name="`bingbot`" `Bingbot` crawls continuously using an algorithmic approach that prioritizes page discovery and freshness. You can adjust crawl rate through the Crawl Control feature in Bing Webmaster Tools, or by setting a Crawl-delay directive in a `Bingbot`-specific robots.txt section. ## How to Block or Control Bingbot To block `Bingbot` entirely via robots.txt: User-agent: `Bingbot` Disallow: / To block specific paths while allowing others, use Disallow and Allow rules in a `Bingbot`-specific section. Be aware that bot-specific sections override the generic (*) section entirely, so repeat any general directives you still want applied. To prevent indexing without blocking crawls, use a "noindex" meta robots tag or X-Robots-Tag header. To limit AI training use, add "nocache" (restricts to URL/title/snippet) or "noarchive" (prevents training use entirely). For IP-based blocking, reference the published IP list at [https://www.bing.com/toolbox/bingbot.json.](https://www.bing.com/toolbox/bingbot.json.) Verify any IP claiming to be `Bingbot` using reverse DNS lookup (PTR should resolve to search.msn.com) followed by forward DNS confirmation, or use [Microsoft](https://microsoft.com/)'s Verify `Bingbot` tool. Bing Webmaster Tools also offers a Block URLs feature and Crawl Control settings for finer-grained management. ## Common Issues & Troubleshooting Watch out for these common problems when working with Bingbot: - User-agent strings are easy to spoof. Always verify `Bingbot` via reverse/forward DNS or the published IP list before trusting the UA. - Bot-specific robots.txt sections override generic (*) rules entirely. If you add a `Bingbot` section, repeat any global directives you still need applied. - Crawl-delay is non-standard and behaves differently across crawlers. Test your configuration and monitor crawl stats in Bing Webmaster Tools. - Accidentally blocking `Bingbot` removes your site from Bing Search, Bing Chat, Copilot, and all [Microsoft](https://microsoft.com/)-powered search partners. - CloudFlare and similar bot protection services may block `Bingbot` if not configured to allowlist its IP ranges. - NOARCHIVE meta tags prevent content from appearing in Bing Chat answers and AI training, which may reduce your visibility in AI-powered features even though standard search indexing continues. ## Quick Reference ### Platform [Microsoft](/content/ai-agent-directory?platforms=Microsoft/index.html) ### Agent Category [Search Engine Crawler](/content/ai-agent-directory?tags=Search%20Engine%20Crawler/index.html) ### Growth Value High ### Official Documentation [bing.com/webmasters/help/which-crawlers-does-bing-use-8c184e...](https://www.bing.com/webmasters/help/which-crawlers-does-bing-use-8c184ec0) ### User Agent String `bingbot` ### robots.txt Entry `User-agent: bingbot Disallow: /` ### Frequently Asked Questions #### Does Bingbot respect robots.txt? #### How do I verify that a request is really from Bingbot? #### Does Bingbot use my content to train AI models? #### Can I control how often Bingbot crawls my site? #### What happens if I block Bingbot? #### Does Bingbot render JavaScript? #### What is the difference between Bingbot and other Microsoft crawlers?
