Crawler & Bing Preview Access

search What we check

Whether your server actually serves Bingbot and BingPreview (Bing's rendering agent), or returns a 4xx (often 406) to them while serving normal browsers.

build How to fix

1. 1 Make sure Bingbot and BingPreview receive the same 200 response as a regular browser.
2. 2 If you use Rails `allow_browser :modern`, it returns 406 to old browsers and BingPreview - allowlist crawler/preview agents or relax the policy.
3. 3 Check any WAF/CDN rule or User-Agent filter that could block crawler traffic.
