Microsoft`s new Bing search engine (don`t ask) at http://www.bing.com/ was launched earlier this year in a direct challenge to Google`s current market dominance. While Bing has been generally well received, it still has a long way to go, with the latest market share for Google above 90%. See our page on the latest market share: http://www.webgrowth.co.uk/latest-search-engine-market-share.php
Microsoft`s clout means Bing will gradually eat into Google`s near monopoly, but most of the same good SEO (search engine optimisation) principles that work with Google will work with Bing.
Therefore Google is still THE search engine you should consider when optimising your website to appear higher in search engine results. We have made Google`s own Search Optimisation Guide available on our search engine optimisation page, which is an excellent introduction to a huge subject.

i am a user of Microsofts BING search engine and it is as good as google for static webpage search. for searching blogs, i think google gives more relevant search results compared bing.
i think that Bing is not as good as Google. Google would still index new websites faster than Bing. Microsoft would still need a lot of catching to do with GoogleBot.
I use both Bing and Google search engine and i dont see much difference in their search results. I use google for searching hard to find academic topics and Bing for general search.
