saturated niche indeed. most of your visitors probably are webmasters that won't click ads for obvious reason.
The problem is that is is so overly saturated with scams and BS that very few people believe the sales pitches.
"It's inexcusable for scientists to torture animals; let them make their experiments on journalists and politicians." -Henrik Ibsen
It's saturated with low-quality attempts at developing high-quality websites.
Look up 'make money online' and you'll find nothing but useless information, affiliate pages, or things like Ruben said. (Neobux) The information just isn't useful... That's why I'm trying to make my make money online blog different - I'm trying to actually give people good information, and I'm not selling anything at all. But I think that, if you can do the right linkbuilding, you'll find success in this niche because good websites are hard to find.
It's true that this niche is heavily saturated, but that doesn't mean there's no room to break into it. You just need to have a revolutionary idea which hasn't been done yet. Share this around the web and market it the best you can, and you'll slowly gain visitors. Making Money Online may be saturated, but there's a good reason for that - people are interested in how to make money online! If they think your website is going to teach them how to do that, they'll not only come back for more but they'll probably recommend it to others.
The only way to make money with this niche is to do something new and creative, just keep working at it and you'll get there.
