First spotted at Webmasterworld, BingBot arrived yesterday, and Bing later confirmed a staged rollout is underway a couple days ahead of schedule.
Bing noted that you'll continue seeing traffic in your server logs mostly from MSNBot, but will transition to (and be completely replaced by) BingBot traffic (Mozilla/5.0 (compatible; bingbot/2.0 +http://www.bing.com/bingbot.htm) over the next few weeks.
This transition period is designed to provide time for Bing to "validate consistency, and provide you time to catch and fix potential issues with the new crawler." Bing said sites shouldn't experience a significant increase of the total crawl traffic from MSNBot and BingBot for any extended period.
Previously, Bing announced details for SEOs on the crawling changes:
- Review your server configurations for crawler access. Webmaster-managed bot access control methodologies, such as robots.txt files, robots tag directives, and HTTP headers, may need to be adjusted if you normally block all crawlers except for specific, preferred search crawlers.
- Bing will still honor all applicable robots.txt directives, including those specific to MSNBot. As of October 1st, if Bing detects separate sets of custom directives for both MSNBot and BingBot in your robots.txt file, the BingBot directives will take precedence.
- If your sites are configured for any special handling based on user agent (such as via the .htaccess file), you'll need to update this for BingBot so we can continue to crawl your sites as before.
- Make sure BingBot has the same access to your site as given to MSNBot. If you previously blocked the Bing crawler but allowed the Yahoo crawler access to your site, you'll need to allow access to BingBot to continue to be seen in Yahoo search results.
Bing also advised everyone to use standard SEO techniques and register their sites with the new Bing Webmaster Tools.
