if you were going to start a Mature site today, how would you do it?

Are you already an affiliate for some mature sites?
That's how to start.
I'm sure there are some old ladies on Camdough you can promote too.

If I was starting out, I´d first sign up to several well known, highly updating mature sites, welcoming you to sign up to my site NatalieKash promoting my site NatalieK.xxx

Once i´ve signed up to these sites, i´d create a blog, maybe a few different blogs linking to each other. Each one, slightly different in niche, but holding the same mature sites. Updating daily, i´d use my social media to promote my site and the websites, twitter, instagram, snapchat & fb, with blogs on WP, blogger & a few other hosts. Also using yahoo, i´d create a group, the aol groups are still looked at too

What makes my mature site different to any other is the personal contact and custom videos option inc. in the fans pass & I enjoy sending personal pics in private messaging most mornings. The personal interaction really helps with retention

yeah, I'd say if you don't have mature traffic already, don't even think about it

Depends on many factors:

How much content do you have?
Is it exclusive?
Can you shoot/acquire more content or no?

But either way I'd go with granny fuckers.
