http://thedigitalpimp.net/2009/08/choosing-niches/This is probably one of the basic questions that get asked constantly.
"Which niche or niches do I promote?"There are several ways you an go about this. You can choose niches that are known to convert well like shemales and gay or hairy. You an choose ethnic niches like Asian or Latina, Black.......these niches are more specific are traffic is more targeted.
You can go for what are called micro-niches like hairy Asian lesbians, to give a somewhat humorous example. Micro-niches are just very specific subniches of a larger niche.
The idea is to find a niche you can get a foothold in, that converts well and has a large enough target audience that you aren't wasting your time.
Another school of thought is to promote what you like. I'm kind of divided on this issue. On the one hand if you promote a niche you like your enthusiasm and knowledge of that niche will help you.
On the other hand you may end up promoting a niche that doesn't convert for a variety of reasons. Too general a niche (not filtered enough) or too much competition.......it's a risk.
Me, I stick to what I like. It's hit and miss.......but I have a lot of fun.
