I've been submitting since March this year.
I'm starting to try different niches now, trying to find that special niche which I seem to be able to be successful with....
Previous main niches were:
Mature, hairy, pregnant, oral, bbw, and to a lesser degree amateurs, ethnic, and breasts.
Recently I've tried Hentai, pee, bisexual, voyeurism, and my last freesite was a teen solo girl site.
It's hard to tell which has been the best niche as there seems to be waves of popularity that I can't quite work out. Of course the amounts of traffic sent to each niche and the variety of sites promoted means it's tricky to pin down the "best", if there is one.
Hairy was great for me for a while, then BBW looked better. Mature has been quite solid, and voyeurism is looking promising. It's a long long learning curve!
