Let me explain better: I'm driving traffic from a social network to a landing page and I'm monetizing it with CPI since most of the traffic (80-90%) is mobile. Besides being mobile, 20-40% comes from USA. That's only what I know about the traffic, nothing about the demographics, etc. I'm already earning a good sum of money but I want more and something that I can use at long term. Here are some options that I had in mind: -> build an email list (but what could I advertise? something related to the niche of my landing page? my visitors are coming to get something free, like a discount coupon) -> open a popup with a facebook/instagram/etc page in hope they will follow -> open a popup with a website of mine and monetize it with adsense -> sell traffic with popups -> ??? I have some ideas as you can see, I just don't know if they are good and which one to choose from.
