As we all know Microsoft has some share on facebook and it is taking advantages rom facebook's content.
It seems facebook is linked everywhere in microsoft's product specially bing.com. Also yahoo is also using bing's crawler.
I think this is a huge challenge to google crawler engine which is based on relevance based ranking algorithm.
These days google seems to be heavily focussed on advertisement and I personally felt that google's first page contains only crap results which is basically advertisement. I am slowly moving into other search engine like bing.com, ask.com..etc

What say sajha users, do you think bing is next big thing in coming years?.

Well,
 Let me put this other way around. Microsoft and Yahoo merged together to grow as a big search engine and basically to compete with Google. Their (Bing, Yahoo and Google) main goal is to reach out maximum users and earn money via advertise. According to the market reports 2010, Google alone captures almost 63% internet marketing (numbers may be up and down little bit). Google is very innovative company which has changed everything in web search and internet marketing.

I don't know if you have used Google tools to monitor and analyze site but I have to do for my blog. I use tools from Google, Microsoft and Yahoo. Compared to Google, it seems like Bing and Yahoo are learning how to crawl and gather information from site, how to analyze web data and process them to reach out internet users.

My own experience:::

My site is not so heavy busy site but get decent traffic (About 10,000 page views) a month and 82% of it's traffic is from Google, 7% from Bing and 6% from Yahoo. It's not conclusion but it will not be over statement if I say people still prefer to use google than other search engines.

Just my thoughts and may not match with other's view.

Just in case if you are wondering which I site I run, it is www.umeshupreti.com. May be you are wonering why IT guy is running photography blog. Well photography is my hobby and I started my blog as a hobby but now it's tool to earn money to pay my bill too. :)
