Q: What kind of information do I put on a Web site once I decide on a niche?
A: That’s sort of an unusual question. I would think you’d typically pick a niche where you have some background knowledge.
My topline advice would be that you should develop some original content.
Rather than pick a niche, because it is hot and sexy and trendy, pick something you know about, so you can write from your experience and knowledge-base, instead of just trying to manufacture content.
Pick something you know and add your unique take to the coverage of that area.
One method for generating content is to create a site similar to what I do with AskShawnCollins.com.
Anybody can ask a question about affiliate marketing, and I answer it via video and text.
Try that and you will eventually have a regular flow of new questions to help generate your original content.
