Obviously I want to rank that main page since it has the keyword in the URL.
However, when it comes to backlinks, would you ONLY invest your $$ on high PR backlinks for the mainpage? Or would the high PR backlinks that was put on your main page spread out through the rest of your pages? Or is it required that you put high PR backlinks everywhere on your site (main page, sub page , etc.)? In other words, does that you mean might have to spend more $$ ?? =P.
