Once upon a time, this young lady was a naive ghostwriter - never once having it dawn on me to apply what I was writing about (tons of marketing materials) for myself.
Now that I've been marketing for awhile, I realize that ghostwriters who write about Internet Marketing have this huge advantage over other marketers IF they'll use it. We're the ones who dig into the in-depth research and learn the complete ins and outs of a system.
We're often the first to apply it (if we're getting step by step techniques mapped out and screen shots taken). We get a jumpstart over the very people who have hired us. We're getting PAID to get an education and actually apply marketing systems!
For example, let's say someone finds out about a new web 2.0 website. They hire me to write a 20-100 page report about it. Well in order for me to do it RIGHT, I get my own account, go through the entire system and learn tips and strateies above and beyond to help the readers understand how to wield its available power.
By the time I'm done writing, I've been paid $20-30 a page to literally promote my own online business! I will have been paid to set up systems to promote myself. Of course, the client gets a nice deliverable too - but this is a very potent perk for writers who will take the time to become marketers and not just behind-the-scenes ghostwriters who help other people make money.
PS - I ghostwrote a wonderful 12 week course on credit and debt for a client recently and what I learned has helped me pay off 6 credit cards and stick over $4,000 in savings toward personal expenses and my kids' school expenses in just 2 months! So it pays to apply what you learn in ANY niche, not just IM.
