I must of missed this.
I do a little promo with MrSkin and quite frankly I have never done well with it. 1 to 3 sales a year in the beginning and the last few years is even worse.
I only started to add a category creating
Erotic To Naughty Celebrities because I had just added a bikini category and had found a bunch of celebs in their swimsuits so it made sense 10 years ago.
As for traffic it added some traffic back then but not much today.
