Adding one more point, Fiverr traffic doesn't even work with CPM, since the quality of the traffic is very low you don't even get back the 5$ invested in Fiverr! I'm also trying some PPC banner, same here, only few clicks and paid very low (Plugrush/JuicyAds) because of the low quality traffic.
In my case the guy advertised the thing saying that most of the traffic is from US, but after few days in my stats I saw a tons of traffic from Google SriLanka domain.... plus digging in my stats majority of traffic was from AWS and "Unknown" netowork, traffic BOT indeed.
