It's easy for businesses to get caught up in Google's expectations for their sites, when trying to market through search. That's certainly a wise thing to do, considering Google dominates the search market by a huge margin. Still, there are other search engines that people are using, and it is also wise to make sure your site is performing to the best of its ability in those too.
I'm obviously talking about Yahoo and Bing, but
Yahoo's share is declining, while Bing's is gaining. Furthermore, if the deal between Microsoft and Yahoo goes through, Bing search will be talking over Yahoo anyway.
Do you take Bing into account when optimizing your site? Comment here.

We don't hear as much about what Bing wants out of a site for rankings, but Rick DeJarnette of Bing Webmaster Center has
shared some dos and don'ts of link-building for Bing. Not surprisingly, a lot of his advice for honoring Bing's policy, does not differ too much from advice that Google would give you. It is, however, still always nice to see how they feel, just to clear up any possible confusion.
Like Google, Bing places great emphasis on quality links to determine its rankings. "Just don't make the mistake of believing it will result in instant gratification. Successful link building efforts require a long-term commitment, not an overnight or turnkey solution," says DeJarnette. "You need to continually invest in link building efforts with creativity and time."
