permalink names for longtail pages

[icosane]

I'm building an authority type site based around 1 main keyword, and plan on having many pages specifically targeting long tail key words. My domain name is an exact match.

Some of the long tail keywords I want to target also include my main keyword. As an example something like "accounting study guide" as the longtail, but if i already had the domain name for "accounting"

In that case how should I name the permalinks? accounting/studyguide or accounting/accountingstudyguide ??

Thanks, this forum is so helpful. As soon as I make some $ i'll join the war room

personally, this is what I would do

accounting.com/study-guide.html
accounting.com/practice-test.html

and so on

looks nice, and google friendly.

don't waste too much time focusing on this
