Why some sites doesn't get ranked in Google but in Bing and Yahoo

[HQP]

Few of my sites e.g. Business-Training-Schools.com and Ultrasoundtechnicians.com doesnt get much visits from Google but these sites get top ranked in Bing and Yahoo. I have tried searching for answer to these question but i did not find anything convincing.

I am relatively new to SEO. But different search engines use different ranking factors into their mix. So what might work for a search engine might not convince the other SE.

Your strategy should be aligned with your Traffic SEO Objetives,

I personally would relocate my SEO Efforts towards Google, because its high volume of traffic, in order to meet your objectives.

I have a similar situation but in the reverse order. I am well ranked in Google, but i am in the dumper for Bing, and mediocre in Yahoo. However, the traffic that i get from Google is very high and meets my SEO Objetives.

Hopefully my comments were of some help!!

Thanks for sharing your situation,

Regards!

I wouldn't worry about it, no one uses Bing or Yahoo!!

Google uses a different algorithm to calculate rankings than Bing and Yahoo (Yahoo is now powered by Bing so both will always give the same results).

While the many factors that both Bing and Google take into account might be similar they are not identical. What might get you hit with a Google penalty (and see your site wiped off the SERP map in Google) might have no effect in Bing.

Here's a handy infographic from pentonmarketingservices.com on the differences between the two.  Of course, the differences between the two are always changing as Google constantly brings out new updates:
