I promote whatever sells...
Right now I promote a lot of pornstars... because I found a sponsor that converts really well for me and it sells like crazy... Do I like pornstars? I'm a girl, not a guy, so to be honest I really could care less, they do nothing for me at all, except I really like to scrutinize their makeup ( I like the smokey eyes) since I am a makeup freak and clothes and belly button rings since I'm contemplating getting one...lol After checking out some girls with "peachy gloss" I ran to Maceys and bought some new Mac Lipglass, that's about the extent of my interest in them.....
I also promote niches like foot fetish, used to promote gay a while ago.. The only interest I have in "foot fetish" in buying new
shoes....
For certain sponsors that have lots of free content, I have been promoting and making galleries for ALL their niches and have gotten sales for ALL their niches even though I am not interested in 90% of them.... I really could give a fuck if I like the niche or not as long as I get paid. If promoting watersports wouldn't be considered such "high risk" in the US, I would promote that too even though I don't like it.
