Bing Tests With Yahoo Remind Webmasters To Get Into Bing's Index [bing.com]
For webmasters, it’s important to be familiar with how the Bing crawler interacts with your site. After the full algorithmic transition is complete, you only need to optimize for one crawler (Bing), as we will provide Yahoo! with results from our index.
During this testing phase, it’s important to look at how your site is showing up in search results on Yahoo! and Bing today, so you can assess if there are any tweaks you need to make or feedback you need to share with the team to make sure your site is accurately represented in Bing’s results.
In particular, now is a good time for you to review your crawl policies in your robots.txt and ensure that you have identical polices for the msnbot/Bingbot and Yahoo’s bots. Just to note, you should not see an increase in bingbot traffic as a result of the transition.
