Today, I has been reg some sites with Bing Webmaster center, and check keyword with it. Here some my keywords on top of Bing.com http://www.bing.com/search?q=luot+net&go=&form=QBRE&qs=n&sk=&sc=8-3 http://www.bing.com/search?q=luot+net+tim+vui&go=&form=QBRE&qs=n&sk= What are your top keywords on Bing?
I haven't paid too much attention to bing but should pay more as it will have the yahoo growth in search share.
"luot" use in Vietnamese, in English it's main "surf" http://www.bing.com/search?q=luot&go=&form=QBRE&qs=n&sk=&sc=2-4
Bing is a bit tricky sometimes, like Yahoo. After some time and working on your Google optimization tasks, your web ranks could improve but the Bing status might be a bit weak. Some believe that on page options are still rewarding while optimizing websites to rank high on Bing.
