Microsoft’s Fabrice Canel confirmed this morning that the brand new Bingbot user-agent is now 100% reside as we speak. The brand new Bingbot will usually be used for crawling 100% of web sites, until one thing goes mistaken and Bing has to fallback to the earlier Bingbot user-agent.
Bing’s affirmation. Fabrice Canel posted on Twitter, “sure, 100% as we speak. We fallback to earlier person brokers the place applicable.”
He linked to the up to date Bing crawler person brokers web page that beforehand listed this because the person agent:
Mozilla/5.0 (suitable; bingbot/2.0; +http://www.bing.com/bingbot.htm)
Mozilla/5.0 AppleWebKit/537.36 (KHTML, like Gecko; suitable; bingbot/2.0; +http://www. bing.com/bingbot.htm) Chrome/ WXYZ Safari/537.36
Mozilla/5.0 (Linux; Android 6.0.1; Nexus 5X Construct/MMB29P) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/ WXYZ  Cellular Safari/537.36 (suitable; bingbot/2.0; +http://www.bing.com/bingbot.htm)
The brand new person agent is documented as:
Mozilla/5.0 AppleWebKit/537.36 (KHTML, like Gecko; suitable; bingbot/2.0; +http://www.bing.com/bingbot.htm) Chrome/
Mozilla/5.0 (suitable; bingbot/2.0; +http://www.bing.com/bingbot.htm)

Some historical past. In 2019, Microsoft Bing introduced new Bingbot user-agent names that match higher with its evergreen Bingbot crawling and rendering service. Then in April 2022, Microsoft introduced a reputation change, a person agent identify change, for BingBot. In December, Microsoft advised us the brand new Bingbot person agent could be 100% reside by January 2023.
Outdated user-agent. Microsoft mentioned it could cease utilizing its historic person agent by the Fall of 2022. That user-agent seems to be like this:
Mozilla/5.0 (suitable; bingbot/2.0; +https://www.bing.com/bingbot.htm)
New user-agent. Bing will use a user-agent that identifies the precise model of Microsoft Edge is crawling your website. Right here is the format for each desktop and cell:
Desktop – Mozilla/5.0 AppleWebKit/537.36 (KHTML, like Gecko; suitable; bingbot/2.0; +https://www.bing.com/bingbot.htm) Chrome/W.X.Y.Z Safari/537.36
Cellular – Mozilla/5.0 (Linux; Android 6.0.1; Nexus 5X Construct/MMB29P) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/W.X.Y.Z Cellular Safari/537.36 (suitable; bingbot/2.0; +https://www.bing.com/bingbot.htm)
“W.X.Y.Z” shall be substituted with the newest Microsoft Edge model Bing is utilizing, for eg. “100.0.4896.127″.
Why we care. You in all probability ought to have been ready for this variation because it was introduced again in 2019. However in any occasion, this variation can influence your website if in case you have any person agent detection strategies for BingBot. Be sure to check your website to see if it helps the brand new person agent. Most websites in all probability don’t want to fret about this, however if in case you have completed any superior bot detection, you might have to take steps to replace these scripts.
Evidently if you happen to didn’t make the required modifications, then Bing will use the previous person agent as a fallback.
