Welcome to the Q&A Forum

I've been looking around, but haven't had much luck finding info or case-studies on targeting long-tail keywords or broad match traffic.  So, for example, trying to target a site about used toyotas.  (Not my term, but provides a decent example)  Theres more motivated traffic searching "2002 Toyota Camry" than "Used Toyotas".  While Used Toyotas make more sense for a site theme from a visitor perspective, I would rather have an article on my site rank for the easier keyword of say Blue 2002 Toyota Camry.  I make more money from long tail keywords than Used Toyotas.  Any thoughts or references about increasing those rankings would be appreciated.  Thanks.
