I'm wondering how premium ad networks (The Deck, Carbon Ads, Fusion Ads, etc..) calculate the payout for publishers. The problem is they have a fixed price for a fixed timeframe (30 days or a week) instead of the classic "for N impressions" price, so how they assign the payout to the whole network?
They have usually 15-30 sites in a network and costs about 1500-2000$ (a lot more for The Deck) for a 30 day campaign. How they could give these high payouts everyone is talking about, even if (I suppose) their cut is 20%-30%?
And suppose if they don't fill all the available ad slots for one month, the payout will depend on how many paying advertisers they have for that month? Could be possible it's so variable?
