I haven't evaluated the chain of my network ads in some time. We been selling some direct campaigns.
But we have a lull now and I want to get the best CPM and performance I can.
Currently I have TribalFusion, Burst, ValueClick.
TF I'm getting a great fill rate but not great cpm.
Burst has a terrible fill rate.
Is there anyone I'm missing that I need to substitute for? Are there other networks now that I should look at?
