Capitalized vs. Non-capitalized keywords in URL

...Different rankings?

[alphacooler]

My new site is setup in the following manner: www.widgets.com/Keyword for all of my subdirectories. During searches on G, "Keyword" is not being highlighted because of its case.

Initially I believed this wasn't a problem because G queries are case insensitive; however I've recently launched a few new subdirectories with lowercase keywords and rankings seem improved. The "rough" control here is that none of these pages have any backlinks yet and are only getting PR from my homepage(PR7). Moreover the targetted kw's have roughly the same competition (+/- 30k results).

So the question is: should I redirect from my old URL's to lowercase ones?

If so, what is the syntax to do so in my .htaccess?

Furthermore can I expect any duplicate content problems with this switch?

Any suggestions to make this as easy as possible?

Thanks so much.

Interesting, i would love to hear more comments on this also. Basically, my main site is made up with subdirectories in Capital letter for the first key term.

If that is what happening, i might also consider changing to lowercase for every word. Didnt know that search engines differentiate uppercase and lowercase letter when highligting.

Does anyone know if this is just a problem with a post-query highlighting filter or does this indicate that capitalized keywords are not counted?

Anyone else?
