Microsoft’s Fabrice Canel confirmed this morning that the brand new Bingbot user-agent is now 100% dwell at present. The brand new Bingbot will typically be used for crawling 100% of web sites, until one thing goes unsuitable and Bing has to fallback to the earlier Bingbot user-agent.
Bing’s affirmation. Fabrice Canel posted on Twitter, “sure, 100% at present. We fallback to earlier consumer brokers the place acceptable.”
He linked to the up to date Bing crawler consumer brokers web page that beforehand listed this because the consumer 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 consumer 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)
W.X.Y.Z Safari/537.36Mozilla/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; +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 consumer agent title change, for BingBot. In December, Microsoft instructed us the brand new Bingbot consumer agent can be 100% dwell by January 2023.
Outdated user-agent. Microsoft stated it might cease utilizing its historic consumer 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 particular model of Microsoft Edge is crawling your web site. 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” will probably be substituted with the newest Microsoft Edge model Bing is utilizing, for eg. “100.0.4896.127″.
Why we care. You most likely ought to have been ready for this variation because it was introduced again in 2019. However in any occasion, this variation can impression your web site when you’ve got any consumer agent detection strategies for BingBot. Ensure that to check your web site to see if it helps the brand new consumer agent. Most websites most likely don’t want to fret about this, however when you’ve got performed any superior bot detection, it’s possible you’ll have to take steps to replace these scripts.
Evidently if you happen to didn’t make the mandatory adjustments, then Bing will use the outdated consumer agent as a fallback.
