I wouldn’t do an everything alternative site. I’m interested in BDSM, rubber, leather, etc., but I have zero interest in cross dressers, trannies, or shemales.
I run a fetish blog and I don’t include them. While there might be some who are into all kinds of things, I really thing that the whole cross dressing / tranny niche is one unto itself.

Look at it this way, if you’re a cross dresser you might not be interested in bondage. And while I’m into bondage etc., I’m not really interested even in seeing men dominated by women.

I think the narrower you make your focus the easier it’ll be to attract and build traffic. My hairy man blog’s traffic doesn’t want to see jocks, my jocks traffic doesn’t want to see hairy men. Why would tranny traffic want to see people tying each other up.

Another thing, by including trannies and shemales in a larger alt site, you might actually be insulting them. Just because you’re on the fringe doesn’t mean you like everything else on the fringe.

Do trannies alone and learn about that niche and that traffic. I think you’ll have more success.

Final point, are you really interested in this or you’re just following it because you have a good adult domain name? If you’re not really into it, you might lose interest really quickly. I’ve tried a couple of times to do something with twinks, but in the end I figured out that I really don’t like them so the domains just sat there.

Funnily enough, I just wrote an article suggesting some top tips for choosing a niche (it’s on a new adult affiliate advice blog that isn’t really active yet) and one of my primary suggestions was to ensure that there is a personal interest.

I agree with what Den80 and ducthien have said, if you have little interest in the subject, you’ll burn out easily and be distracted by something else within a couple of months at most.

My most successful sites are sites that I have a deep interest in, I’m motivated to post and update them, and really write for them, through my own interest. The sales that come from it are great, better than anything else I work on.

I can write about all kinds of action and all niches, but when you’re doing it for yourself rather than as I do for paying customers, it’s far too easy to abandon projects if you have little interest.

Also, I don’t know what it’s like elsewhere, but the cross-dressing community in the UK is extremely segregated from the rest. There are a lot of men involved that have zero interest in the sexual aspects of it, it’s a confusing issue and one to only deal with if you are actually involved yourself and can understand the community and the various motivations. As Den80 says, you risk insulting people by associating them with things that they might have absolutely no interest in.

I’m not sure if you’re considering a social network style site, but having attempted to build a social network previously, I speak from experience when I say that it takes a lot of work, a lot of investment and a lot of money. It’s a big gamble. The basic hosting options are rarely adequate for it, the platforms are so buggy you’ll probably need an IT professional several times in the first year, monetizing it without adding a membership model will probably not cover it.

I hate to sound so negative, but I too would just build a regular blog, only if you have some interest. That’s just my opinion though. Good luck with whatever you decide to do with it!

I strongly believe that your adult site can not be successful if you do not have an interest in it even if you outsource most of your work needed to maintain your website.

I have been there, done that. I opened a site in a strange niche but after a week or two abandoned it because the lack of interest.
