I own a relatively new website (3mo) service which I would like to grow. The service already has 2000+ registered users mostly attracted through Adwords. The site is already indexed in Google and Yahoo but positioned very low. The niche of the service is not crowded and the primary search terms are not very competitive (low to medium judging from adwords and the number of similar sites).
The goal of the project is to bring more free traffic to the site as well as raise it in Google and Yahoo Search for the primary 2 search terms (one keyword and one phrase).
