Search with caps and without caps

When i search with

"Best freebie" with B caps in it my website appearing at first page of google.com in top five but when i search "best freebie" it's at 2nd page.
Why its like that?

 

Google treats upper case and lower case versions of a keyword differently.

It is likely that the anchor text in backlinks to your site use the uppercase variation more often than the lower case.

 

That's interesting... different results appear indeed. Have it been always like that or it is something new? I mean that case sensitivity thing.
Anyway.. I see your site on 17th position both cases.

 

But it was like that as i described.

 

I have never seen that before. Truely amazing. I always thought it made no difference.

 

i dunno what you people are talking about. i can't find any differences in the two methods described here. whether you search with caps or without it, you will get the same result in either case

 

I got the same results in both case. your site is at 9 position right now with both keywords................
