First of all I want to say thank you so much to all of you. Your responses are really helpful and I gained a lot of insight from them, appreciate it! You guys are right the focus should be on the payments not just the signups. So far non of the users who signed up purchased the courses. I tried to reach out to the ones that signed up but none responded. I'm going to talk to more users and get more feedback as you guys suggested. As for the kind of ads, they are targeted to a specific group by location, age, interests, and search queries which we believe will be our target customers. We are doing the ads through Google.
