After spending about $50 for traffic. We have this

I used Peakconversion to narrow down to two landers, both perform at a similar level.

Here is a screenshot of the placements' stats,

Day 2,
Pick lander 1 as the winner, made three variations of it LP1v1, LP1v2 and LP1v3.
Start a new campaign using the three with exact same settings (disable a few placements which cost >2X the payout)
After spending about $20, it looks like this

With landers' stat look like this

I don't really know what to do from here.
I have also created another campaign with lower bidding (CPM $0.8) and haven't got much data yet.
Do you guys think this looks like campaign that can get a positive return in the end?
