its my first tgp im making now, i was thinking what niche?
I was thinking ill try just a general niche: hardcore-teens-babes-ethnic(latina,ebony,asian).
Is it a good idea to put more niches, like fetish, in it too or is it a better idea to concentrate more on a less number of niches to get more targeted traffic?
I submit also free sites and thats very niche specific, and my conversions are much higher then my galleries.
