Selling nudes online is easy if you find your niche. Specializing in something is not a mandatory step, but if you want to find a more target audience and thus ensure that money rolling in, it is advisable. Think about it: the more niche the photos you sell are, the less competition you will have and therefore, the more you can charge for them. Focusing on a specialized niche also means that you will have less people looking to buy, so at the end it’s a balancing act. What you can do, is focus on a certain fetish or niche, but not limit yourself to only that and sell regular nudes as well. Just find the market that you want to explore and milk it: BDSM, foot fetish, bondage… the list is endless.
