Ok, so not quite sure if I got the right sub-forum for this one. But, I had a problem arise this morning that I'm attempting to suss out. I have a site where I rank nr6 for a desired keyphrase and nr 8 on another. I'm starting a new marketing effort for the site. Should I:
1 - Focus on getting these two key phrases ranked higher (the traffic they currently bring is nice, so I assume getting higher would be nicer
2 - Only focus on the least competitive one of the two and a new keyphrase that I'm ranking about nr 50 on?

I know in a perfect world, focusing on all is best, but am time and resource limited on the new campaign. I'm thinking its better to increase what I have in-hand to a higher ranking, but looking for opinions.
