My First Test

[rickgwork]

I'm new to this. I ran a test with a Golden Goose offer, and after two days of spending a total of €50,259 on a Propeller Ads campaign, I got 27 conversions and revenue of €10.45, which is an ROI of -79.2%. My question is, is it possible to optimize a campaign with these numbers, or should I simply test a new offer? What would be a recommended ROI to make a campaign profitable? -50%, -30%? Are there other metrics that are important when deciding whether a campaign could end
