In the first day I lost over $300. But after one month I made $600 spending $1200. Sometimes its hard to tell whether you should stick or not. Post whatever campaign you have. 1. The number of pageviews, and CTR 2. Along with how much money you made. No need to reveal niches or what offers you are running or keywords you are using. I will tell you whether you should continue and give maybe helpful advice.
I have a campaign 1.8 million page views per day with 0.35% CTR with 0.45% conversion ratio and netting $15 per sale... What do you think?
Its just common sense to stop a campaign if you are just loosing money from it. There no Expert required to tell you that you are loosing money (especially when the expert himself has lost money in it ).
