Why Your Unique Value Proposition Sucks and How to Fix It
UVP -- Not easy to do with a commoditized product like porn but there are niche markets were there is money to be made.
I would create a traffic funnel to relevant well constructed landing pages.
If your content has not been distributed on the tubes -- all the better.
All video should be streamed MPEG-Dash EME HTTPS so it cannot be jacked.
Don't waste your time feeding the tubes just buy network traffic as cheap as you can -- target countries known to buy. But these are not limited to only the countries that bought 10 years ago. A lot depends on your niche. Asian girls -- Asian traffic Japan, South Korea, Singapore, even some filtered China. Get creative create a CTA touchpoint ( call to action (or, a reason to buy)) save 1/3 when you buy a 3 month subscription -- when all the money is yours (no affiliate involved). Don't be afraid to be different when you have a UVP -- you are on your own playing field in that customer's mind.
Use Twitter for social media funnels and Facebook -- very carefully -- for link and traffic authority. Even do an adult Blogger utilize the traffic on that domain. Don't spend too much effort on social media as you are always in the edge of a TOS termination.
We do some of these things but on our scale it is difficult to do all these things properly. Select a few that work for you and run with them.
