Need help from experts to scale up

I have been promoting chaturbate which is an adult webcam site. Mostly I am doing it from facebook by posting comments on sex related pages. I even made one youtube video showing how to register there and also a blog regarding the same. I am earning around 5-6$ a day for the past one month... But i need to scale it up now. So what should i do other than facebook. Most of the traffic I am getting is through facebook. I am aslo posting on a few forums..but that isnt helping much. Is it that I need to make better posts? On an average me getting 1 lead after 10 clicks
