Even our college textbooks from which I teach college classes in marketing management, are being revised because of this new revolution. The internet is vast and lacks location. The more specialized you become, the more business you will attract because people today want experts. They want people who are more focused on their specific needs. The one thing NOT to do is to stray and then line extend.
Line extension is a killer.
As long as you remain true to your core customer or competency, you're better off. You can create content, anything electronic, and get it to spread. It's good old viral marketing. You want to give away stuff that can multiply by itself. Wanda Loskot is author, speaker and professional business coach specializing in Internet marketing.
