Different results for caps versus non caps

[coldfused]

Say I have a term I am optimizing for like:

Red Widget

How can the results for "Red Widget" be so different from the results for "Red widget" or "red widget".

I mean literally two and three page differences.

I am optimizing for "Red Widget" and the results are page 3 and climbing, which is good. But for the term "Red widget" page 1.

someone please explain this and how would you go about correcting the problem?

There was a long discussion earlier this year on Google's odd case sensitivity:

Different ranking when using capital letters [webmasterworld.com]

To be honest, it's a bit of a mystery to me, and I'm at a loss to find a consistent pattern in which sites perform better or worse for different letter case combinations. Note that the vast majority of searches are all lowercase, though, so I would make that your primary target. There's variation in searcher behaviour for things like certain brand names and acronyms as I recall.

Thanks Andy.
