Hi Op. I'm tagging to follow and also I would like to point out some questionable things I think you are doing right now. You're cutting too early You cut campaign 2 on $14 ad spend. Is campaign 1 and campaign 2 the same offer? If they are, why aren't you doing 2-3x the offer payout before making cuts? I assume you are doing this because your main testing budget is small. Native ads need minimum 10k testing budget. If you don't have 10k then you should go to a cheaper traffic type. You're running one offer I've ran a network and negotiated deals between advertisers for the network before. I've also ran campaigns for networks that have burnt me thru shaving, high restrictions midway thru the campaign. DO NOT PUT YOUR EGGS IN ONE BASKET. Get more offers. Work with more networks. A good offer can take a campaign from red to green. Advertisers and networks set 180 day contracts typically. Often times advertisers do not pay on time, so the network has to shut the offer down before resuming. Advertisers and networks shave. See if you can get another network with the same offer and try to compare the ROI.
