Why Supply Is the Next Performance Lever

Advertisers know when their campaigns deliver impressions, but they don’t always know which supply sources drove app installs, purchases, subscriptions or other outcomes – making it difficult to move spend toward the inventory that actually performs. This is why supply-level conversion measurement matters: it helps advertisers see what’s working and optimize campaigns while live. 

For many advertisers, campaign optimization has historically focused on audiences, creative, bids, and delivery. And while those inputs matter, they don’t tell the full performance story on their own. Two supply sources can deliver similar reach or video completion rates yet produce meaningfully different downstream results. Without a closer look into which inventory contributes to actual conversions, advertisers may keep spending against supply that looks efficient but isn’t driving or delivering the final outcomes that matter most. 

Nexxen SSP Performance Deals help advertisers see which supply is performing best to achieve desired outcomes, then use that intelligence to optimize in flight and move spend to high-performing supply. Through Nexxen’s partnership with global app measurement and attribution partner Kochava, advertisers can connect impression delivery to conversion activity across mobile, CTV, and digital channels (including outcomes like app installs, in-app events, subscriptions, purchases, registrations or other advertiser-defined actions, depending on the campaign goal). The value is not just better reporting after the campaign ends – with in-flight visibility, advertisers can use performance signals while there’s still time to act. Nexxen can help identify which supply sources, device types, contexts, and frequency strategies are contributing to stronger performance, then make optimization recommendations that help buyers shift spend toward the inventory that’s driving results – giving advertisers a more practical way to evaluate supply.  

The closer advertisers get to understanding why (and how) performance happens, the better equipped they are to improve it. Supply-level conversion measurement delivers that visibility while campaigns are still live, leaving room to optimize before the budget is spent. Nexxen’s partnership with Kochava enables supply to become a more accountable part of the performance strategy, while giving advertisers a clearer path to connect media spend to business results and ensure every impression works harder.
