My site does so much better on google than yahoo. Not sure why.

[konrad]

Hi my site is: http://www.westpenndentalcenter.com, and I am leading traffic website for denture repair, denture reline and duplicate dentures keywords.
I am running blog under the same domain http://www.westpenndentalcenter.com/denture-repair and i use two sitemaps.
I got my site to number 4 or 5 on google by now, but when it comes to yahoo they don't want to accept my main page or i am not sure what the problem is. For whatever reason I am showing like 25th on yahoo, and bing.
My goal is to get to at least top 3 on yahoo, but it has not change over last 2 years no matter what i do.
How long does yahoo usually takes in order to recognize website as not new. I am already page rank 3.
Thanks for any tips you guys may have for me.

There is no season to their reason, Konrad, and being followers behind Google, there is no indication their import nor processes will change soon.
