It's hard to say without knowing which traffic source you are using....each one has different tags for tracking different things
You can check what tag tracks which variable at your traffic source in their help docs and add the tags accordingly to your
Also, have you checked each variable in
and for mobile pops the placement is where the traffic comes from, for example, on popads a placement will have an ID number such as 85239. Each placement has a different number so you can see which one is profitable or not.
Hi, aloevera!
Regarding ZeroPark: my advice is to work the targets more than the sources. Why? Due to the fact that the targets are a more granular option. Sometimes, you can have sources that are losing money but inside them you've got targets which are profitable. I advise you to cut sources if you’ve already optimized targets for those sources and costs are 3/4 times the CPA for that segment.
We use this method because the performance of the sources depends not only on the segments but also on the targets inside the segments. It’s easier to define when to stop a target than a source. If there are no conversions in all targets of that source, I’d recommend you to stop the source.
Moreover, if you have a source that isn’t profitable but inside it you have a profitable target, I advise you to create a so-called target campaign. You just include those targets.
Another good advice: work the keywords by creating Keyword campaigns. Try to do some tests on some keywords. It both reduces your costs and improves the performance.
I hope these tips will help you get the whole juice on ZeroPark!
Cheers!
