I was thinking about this a week ago or so when I was trying to choose a domain name.
To be honest I'm still not completely sure as how to go about it.
I found this article that gave me some insight:
http://www.nineyards.com/2006/keyword-url.htmlI became concerned that if your key phrase is kinda long, a hyphenated URL can start to look somewhat spammy.
After reading it I just decided to stick to the non-hyphenated url.
Here's something I've noticed. Most of you probably have heard Holly has a new blog called "Honest Marketing Movement". If you go to google and search "Honest Marketing" notice how google has highlighted "honestmarketing" in bold green in the url honestmarketingmovement.com even though your search term was "Honest Marketing" with a space.
Does that mean google recognises key phrases in urls NOT seperated by hyphens?
