On average, less than half of programmatic spend becomes a qualified impression
The best-performing advertisers choose the right sites to buy and keep checking them for the whole campaign. Less of their budget is lost to fraud, ads nobody sees and low-quality sites.
Maridion curates what goes into the buy. AfterBid keeps checking it while the campaign runs.
% of programmatic spend that reaches a fraud-free, measurable, viewable impression on a genuine site
Every domain in a deal has earned its place.
Each deal carries only the domains and placements worth bidding on, so your DSP sees fewer, better-qualified bid requests.
