Directory Structure Help

For a little bit of background....

My current structure is:
www.domain.com/CATEGORY-Keyword1-Keyword2/Title (doesn't rank well)
www.domain.com/CATEGORY-Keyword1-Keyword2/ (just a place holder, does not exist)
www.domain.com/Keyword1Keyword2/Category (ranks very well)

What I want to do:
I am thinking of changing...
www.domain.com/CATEGORY-Keyword1-Keyword2/Title TO www.domain.com/Keyword1Keyword2/Category/Title

Because the current pages for www.domain.com/CATEGORY-Keyword1-Keyword2/Title are not ranking well at all. Some pages don't even get indexed.

Would you recommend this change or should I keep it the same?
It would be a bit more of deep linking but at least the directory up exists in all folders and the page before would have PR.

I appreciate ALL responses!!!

 

We have tried almost ever combination so far, the best we have done is the following:

www.domain.com/keyword phrase 1 (the category)/keyword phrase 2 (the subcategory)/title (the detail page)

The closest documentation from Google on this is for the description, but we use it for the <title>

Hope this helps.

 

Go ahead and change to the one which is working www.domain.com/Keyword1Keyword2/Category

more closed the keywords to domain the better it is.

 

Remember I am adding TITLE at the end of the category. That is what you meant right?

 

For me, I see no sense on having "category" at the end of the domain. For me,
"www.domain.com/Keyword1Keyword2" format is enough.

 

Category is needed to classify even further. Those pages are ranking so I will not remove them.

 

YEs, you said it right. I meant title at the end.
