I've seen hundreds, even thousands of topics on webmaster forums about the best performing niches. One thing that people should understand, is that people that actually found good niches, won't spread what they are .
That's why I've created this thread to talk about niches that performed very bad for you. For example, I've created a website in the tuning niche and had 5 to 10 clicks daily but they only paid $0,01 - $0,03 per click
What were the worst niches for YOU?
