ExoClick is the network most adult media buyers test first, and for good reason: the self-serve platform carries enormous volume across banners, native, video pre-roll, popunder and push, with real-time bidding and an API for anyone scaling campaigns. Targeting is granular down to site, zone, geo and device, so disciplined buyers can carve profitable pockets out of broad inventory.

The breadth is also the catch - the open marketplace means quality varies by placement, and you'll burn a little budget learning which zones convert. Treat it as a platform to optimize on rather than a set-and-forget buy and it rewards the effort. For most operators it's a default core network, not an afterthought.
