02 · Behavior

What Bingbot does

Bingbot crawls pages automatically for the Bing search index, with desktop and mobile user agents. Its rendering engine is regularly updated to the latest stable Microsoft Edge, which is reflected in the Chrome/W.X.Y.Z part of the user agent. It honors robots.txt and the Crawl-delay directive.

03 · Impact

Why Bingbot matters for your site

If you allow it

  • Required to appear in Bing search
  • Honors robots.txt and Crawl-delay

If you block it

  • Only for pages you do not want in Bing (use targeted Disallow rules)
  • Spoofed bingbot traffic should be blocked after verification
