Know Where Your Audience Lives
advice from Jacob Dayan
Focus your efforts on where your audience is most present. There are some great tools around the web to find out some key demographics and psychographics about many major social media sites. Keep your eyes open for industry-specific forums and pay attention to the advertising opportunities there. Most forums will not let you post for free, but they are a great way to reach a rich target audience that will be more inclined to purchase your goods/services.
