Yes, Google is the dominant force in search engines at the moment.  But that doesn't mean you should ignore Yahoo and Bing altogether in your link building efforts.  While Yahoo's share of searches is declining, Bing's is continually on the rise.  And, if Microsoft's deal with Yahoo goes through, Bing will pretty much take over Yahoo anyway.  Here are some tips to create effective link building on Bing:

1. Branding - Create your brand and market it everywhere: website, blog, forums, social media, etc.
2. Network - Seek out "professionals" in your field, industry experts, bloggers, etc., and build a rapport with them so they are well aware of who you and your brand are.  That can go a long way in upping your "expert" quotient with search engines.
3. Press Releases - Don't underestimate the power of a press release.  Places like prlog.org allow you to create and distribute a press release for free to places like Google News and creates an RSS feed for distribution.
4. Article Submissions - Creating and submitting articles about your areas of expertise to article directories, like ezinearticles.com, both increases your online presence and makes you appear to be an expert; two things search engines value most.
5. Interact on Blogs and Forums - Blog posts and forum discussions are great ways to interact with other professionals and possible clients as well as give advice and show your "smarts".
6. Social Networking - I can't stress this enough!  Facebook, LinkedIn, Plaxo, Twitter, Trulia, Zillow, etc.  You can create a link back to your site in your profile on all of these places.  Make sure you connect with "experts" in your field on all of these sites.
7. Newsletters - Create an email newsletter to let your contacts know about new and important information.  Use your sphere of influence to create a larger internet presence.

When considering your search engine optimization, concentrating only on Google may not be as effective as you want.  Don't forget to use effective link building on Bing as well.  It's definitely an "up and comer".  Remember: If you need help with any of this, your real estate virtual assistant can help!
