Zeropark

Guys quick question is zero park traffic BAD? i spend like 40$ and got only 1 conversion. -39$ IN ROI. Though i am using tracker and offer has decent landing page. And this offer was converting like crazy with different network.

You should test then optimize placements.
You must have a tracking software to see where the conversions are coming from then optimize your campaign.
The important thing in zeropark is to set 1 or 2 $ for each target if you don't do that you will have 99% from one placement.
Good luck bro.
