If you are really want to go for good start then health niche is the best , it can give you more exposure in less efforts . so according to me health niche is better. Thanks / Best Regards WDC
I often think that niches around women may be good, men tend to ignore ads, some older women on the net do not really understand what they are doing and click and read ads. I think men search for stuff they are shy to discuss, like health related.
Niches ordered in the order of searches, not necessarily in order of monetary gain: 1) Sex - but this is difficult to monetise with passive type monetisation methods like Adsense 2) Health niches - everybody is searching for something in the health niche - make it informational 3) Internet marketing - thats why we are here - easily monetisable as well...
