I have a new site ( 4 linked domains to a main one ) its based on seflies (sexy and nude ) and wondering what would be the best way to promote, market and at some stage sell. so far i have a facebook page, twitter page. few banners from google and is a cheap but useable simple image sharing script. ideas?
Yeah, go into a different niche. Stop trying to make money the hard way. At the end of the day, it's all about how much money you made - not how smart you are.
Research the kinds of sites your target audience is currently visiting. As your site is a very visual based site and probably steers towards a younger demographic maybe look into sites like instagram.
It is without doubt how a selfie can help improve as well as promote your brand. Be cautious that there is no control over this 'selfie'. That means, anyone can see it along with the comments attached. The best way though is how you market them. Try joining to Google communities and build engagement there.
I think you should try Tumblr and Pinterest as pictures work best there. There are 2 clients of ours who had this exact problem (they own nude pic blogs) and my team and I used Tumblr to fix the problem. Just watermark the pictures, then you are good to go.
