Internet Marketing Tip: Social networking sites have become a top priority for internet marketers because of the sheer volume of people who use them, especially Facebook. However, there are some do's and don'ts you should follow to make the most of this marketing opportunity. Do post your real photo as a profile picture instead of logos, luxury items or other impersonal objects. Provide some personal information instead of just trying to promote your product. Talk about your hobbies and interests, as well as your favorite sports, movies and books. Let potential buyers see that you're a real person, not an entity.
