Bot 2.0 Replacing MSNBot 1.1 For Better Crawling
Microsoft will be saying good-bye to MSNBot1.1 that will be replaced by the next bot: 2.0B. The team has said that new development will enable Bing to gather better information from a bigger number of websites that Microsoft indexes across the globe.
Here’s an extract about the new replacement from the Bing Community Blog:
“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 (+http://search.msn.com/msnbot.htm)
The only Bing user agent you will see in your logs from this point forward will be this, our new bot:
msnbot/2.0b (+http://search.msn.com/msnbot.htm)”
It is said that the new bot will conduct better and richer crawl accordingly.
