It's not an easy task. I see it as accelerating what would happen in a natural manner. Which is, accelerating the discovery of your site and subsequent linking. It's not easy. For a client there are certain sites that focus on the kind of person likely to be a purchasing customer. Especially when focused on the demographic, getting the word out to those likely to purchase your good or otherwise engage with your site, the traffic and awareness can matter more than the link juice.
