The only conclusive result offered is that Bing is substantially harsher about domain age. From a Bing vs Google SEO test on seowizz.net, Tim Grice suggests the title tag may have a slightly stronger influence on Bing than it does on Google - but domain age is a definite.
Tim also suggest another difference in that Google seems to award less then Bing for backlinks. Bing seems to favor backlinks rather than a well optimized page based on results from the second Bing vs Google SEO test of the series. The test shows a well optimized page that holds the #1 Position for Google is far lower ranked in Bing - because it doesn't have as many quality backlinks as it's competitors. For the test keywords, the Pagerank 2 site is ranked higher on Bing than a well optimized PageRank 5 competitor. These are some interesting results considering the differences of both search engines.
How do I optimize specifically for Bing?You don't. The reasons for the differences between Bing and Google SEO come from situations you can't control. Domain age and backlinks are out of our hands, there is no difference in on-site SEO for Google and Bing.
Bings pretty much using the same Microsoft results we've seen with msn and live but with a cute Googly interface and a couple cool features. My belief is that it will get much more cash orientated in the future. I'll keep my eyes open, but I'm pretty sure DEO is going to be the same as SEO
What is DEO?Decision Engine Optimization - Well it's a 'Decision' engine isn't it? Grow up, Microsoft.
Have you seen the Bing TV ads? They are ridiculous, they make it seem like they are curing cancer. It's Google with some pepper, not everyone likes pepper - calm down, Bing.
