Just thinking... keyword instead of content in setup?

My domain name contains my main keyword, but not the second main keyword.

So I was thinking, would it be an idea to use second keyword instead of "content" in my URL setup?

E.g. www.city-keyword.com/country-keyword/ (CMS)

What do you think?

It likely won't help too much. I would, however, make sure that 'country' was somewhere on the page itself in a heading tag of some sort.
