You HAVE to pick one thing and exhaust it. For instance, if you launch a new product through social networking, you should be spending 8-10 hours a week just on social networking. The web changes too often for you not to dedicate a significant amount of time to your efforts. You should also pick products that are in a niche you belive in and like...this makes so much easier to promote sales. I'm going to suggest www.trafficmasters.tv to you. That's how I got started and have been very successful.
