Thanks for the reply Travis.
I must have posted earlier as you replied and missed your first post. You got to the heart of what I was trying to say. What particularly bothered me was what I original posted, as the url looked like this xxx.soapbenefits.com/how-to-make-homemade-soap, then article title (how to make homemade soap) and blog title (soap benefits)
Like you said, it's hard not to write an article on something like homemade soap in a 600 word article without at least mentioning soap at least four of five times, I was thinking... mmm, including title url, etc.. I'm at 2% keyword density here.
With so much emphasis being put on making sure to non optimize keywords, having the keyword twice in the url bothered me. I've already implemented your tips and removed any reference to the keyword in categories too. Thanks for the help, and you're right I probably over thought it to much.
