Let's say you're starting a new site and you only have $50 left in your budget to advertise and get new people in. We'll say that whatever money you get from people buying whatever you're promoting won't show up in your pocket for at least a month. What do you think is the best place to get the most bang for your buck, with the highest quality leads? I hear a lot about Facebook ads, but I don't pay much attention to those myself. AdSense is also suggested, but I'm not sure what kind of leads that generates on a very limited budget.
