I would like to know your opinions on the dollar per click plus niche on the net. Who is paying big time for their ads. I'll tell you one thing. skateboarding is not a high paying niche.
no one is going to tell you that, because it would mean only more competition for them. Anyway, gaming (xbox, playstation, wii) isnt a 1+ dollar paying keyword also, but if you have enough traffic, any keyword will do the job.
There are alot, but the competition is very tough, think about something like mortages and than look at all the competion that is involved in it. Try to find a niche that is not to tough to break into, and go crazy! Accounting is good btw!
dunway.com for you. in all niches, if you forget about PPc and optimize for ppa, you´ll get much much more (even if doing the ppc for the ppa on your site, luckily)
