Are these statistics normal??

Here is a screenshot from my google analytics. What I am wondering is if the ratio of google searches is too high compared to bing and yahoo. The reason this bothers me is it makes me wonder if my site is being properly indexed by bing or yahoo and do i need to do something about it. Can anyone confirm if the ratios between google and yahoo/bing are normal?

Seems about right to me. I just checked my analytics and for about 20k visitors this is what mine were:

Google-15,005
Bing-274
Yahoo-134
aol-26
live-18
search-14
ask-13
msn-12
altavista-1

I have been checking my ranks in Yahoo and Bing and I actually rank higher in Yahoo than I do in Google but still get no search traffic. I think its just the amount of users that Google as rather than optimizing for Yahoo and Bing.

dont worry about it to much... it is perfectly normal going by my own stats too

Look at mine, and decide for yourself:

The reason this was annoying me was that i've tried submitting my sitemap to yahoo and bing and they still never index anywhere near all my pages. Google on the other hand when I gave them my sitemap in a very short space of time came along and indexed all my pages. Before i gave them the sitemap they were only indexing about 1/3 of my pages.

I've found that the submitting a sitemap process to yahoo and bing isn't as clear cut as with google and after i've submitted it, they still don't index all my pages which was making me wonder if they were just ignoring or not even looking at the sitemap. Or if i didn't submit it properly and this was explaining why the ratio of google to yahoo and bing had such a huge difference. I expected there to be a big difference but not this big??
