MSNBot 1.1 is retired

The Bing team has been talking about its new crawler (aka bot), MSNBot 2.0b, in this blog for quite some time now. We have made numerous improvements in its performance, addressed some webmaster concerns, and published detailed information on how to control the bot with a robots.txt file. Today we are announcing that the new bot is fully operational. This development will enable Bing to do a better job at gathering the information we need from the myriad of websites we index worldwide.

As MSNBot 2.0b enters full-scale production, the time has come to retire our previous generation bot, MSNBot 1.1. By the end of the first week in November, you will no longer see the following user agent in your referrer logs:

msnbot/1.1 (+

The only Bing user agent you will see in your logs from this point forward will be this, our new bot:

msnbot/2.0b (+

This event is a major milestone for the Bing engineering team, and we look forward to the positive developments that this bot will bring to our search engine index and thus to Bing customers. We want to specifically thank all those webmasters who provided us with valuable feedback as we ramped up the production of the new bot. Your assistance and cooperation was essential to making this milestone happen.

Stay tuned for more information about this and other developments from the Bing engineering team. We’ll have a lot more to talk about in the coming weeks and months.

If you have any questions, comments, or suggestions, feel free to post them in our Crawling/Indexing Discussion forum. Be back at you soon…

    Does this mean your search engine might index something other my sitemap now?  Because that would be awesome.

    Will you be able to offer a stronger set of webmaster tools as a result of the new bot?  It would be great if you could provide deeper metrics and data that rivals or exceeds that of Google.

    it would be interesting read somethign about the improvements of the Bot. You know, it's a decade that you are going around with it, at least, since you announced the new version, you could have revelead some stuff.

    I still waiting it on my web site as well as understand how it really crawl pdf files.

    As has been said before will you be offering more webmaster tool. For me google analytics is a great application and tool for my blog but it'd be nice if there was an alternative.

    So as webmasters do we have to do anything differently?

  15. raphael

    Does this change include the msnbot-mobile ?

  16. rickdej


    No, it doesn't. This announcement only pertains to the MSNBot 1.1 crawler.

    No offence, but I wish you guys would moderate your forums, it is such a hassle searching for information from any kind from this forum.

    Spammy comments do not help people like me who are searching for very specific information – it wastes our time and shows callous disregard for individuals Bing is trying to win over.

    You should work on improving the search results in other languages, not only in English. And find a way to index sitemaps of more web pages.

    Is this new crawler seo friendly ?
