Forget all of the keywords given on this thread. Someone who finds a niche does not give it away, otherwise there is a risk of competition increase. Find your niche for yourself and keep it for you! thats my recommendation
DUI/anything law and then green/eco friendly companies seem to be giving very high clicks, somewhere in the .50-$2 range.
Nope. It aint a good niche because it's over populated and doesn't even pay that much. Competitive, but yep pay very well. I think insurance is one of the highest paying here in the UK. It's just a shame about all these damn price comparison sites taking the business. OP: Find unique niches that very few blogger/webmasters are discussing. That Google Adwords Tool is perfect for tracking down some hidden gems.
At the moment quality finance sites are doing well as despite the general perception, Finance Companies are now becoming very choosy at where they advertise etc which is good for the quality sites and perhaps not so good for the MFA sites.
The highest paying niches are anything finance, health, debts, credits, education, web hosting, and conference calling. These are the highest that I know of but they are highly competitive niches. So need a lot of hard work to be able to achieve a decent income from this. But if you are a hard worker and then everything is possible.
BTW. about the finance niche, anything that has to do with mortgage has fallen now and is no longer making as as it sued to be. I don't know if its me only but that's what I know. Thanks JulieV
Health, Finance are popular niches that pay really well. I've heard that travel is quite good, but I haven't tried them out yet.
Insurance, creditcards, loans, student loans, car insurance, weightloss, make money, yahoo domains are the best
