Popunder CPM Question
 

I am currently running a popunder campaign on Juicyads. When I am setting up my campaign it has my CPM bid, I've ran lower cost bids 2.50 per 1000 impressions and I have ran higher bids 3.50 per 1000 impressions.MY question is at the end of the day I got 12,000 impressions for the 2.50 bid and 6,700 for the 3.50 bid, what is the purpose of higher bid when you get more impressions with lower cost? Is there something I am missing?

Well... welcome to media buying. It's a road of loosing money until you get it right, then you'll make money and have to work every day at optimizing or you start loosing money again.

You bid in a system of real time bids, so other buyers bid as well. They bid on things such as GEO (country), type, device, browser, OS, niche and every single parameter they can to optimize.

If you just blanket bid on all GEOs with a CPM price you will get more traffic that if you bid on say UK MAC traffic. But you also get crappy countries like India that is worth maybe 0.4 CPM tops.

That was the super short version. Please pause your campaign, go google media buying. Read for a few days straight. Then go back and create a new campaign. You also need to test multiple sources, you can find a list of adult traffic brokers here: Adult Traffic Brokers – Adult Media Guide

in short: the cheaper the CPM the crappier the sources

The million dollar question. Welcome to hell.
