Or do they sell the excess inventory you dont to a larger ad network??
Sorry guys, but you'll have to blame the strange ads on Google =)
Publishers on isocket can put another ad network's code in as a default setting - so that when their ad space isn't sold directly, it will default to AdSense / whatever.
We do not arbitrage or sell your unused inventory for our benefit.
In terms of our business model - yes, we're actually commission-free. It's a flat monthly fee. Sorry to do this to ya, but we haven't publicly announced what the pricing is yet.
Cheers
