How Yieldmo boosted mobile inventory profits by packaging it with contextual intelligence

The challenge

Yieldmo, a leading mobile advertising platform, faced a significant challenge: a growing proportion of their in-app inventory was becoming unaddressable due to IDFA deprecation. Buyers were reducing spend on inventory they couldn't target or measure, causing CPMs to compress and overall inventory yield to decline.

Yieldmo needed a way to make their in-app inventory addressable again — without relying on personal identifiers — so that buyers could apply audience targeting and pay premium rates.

The solution

NumberEight integrated its Deep Contextual product with Yieldmo's supply-side infrastructure, enriching in-app ad requests with rich contextual signals derived from on-device content analysis. This allowed buyers to understand the context of each impression — the app category, content theme, brand safety signals, and user intent — without accessing any personal data.

NumberEight also layered in Affinity Audience segments where available, giving buyers the option to target by both context and audience affinity simultaneously — a uniquely powerful combination for mobile inventory.

The results

By making previously unaddressable inventory valuable again, Yieldmo saw dramatic increases in both addressability rates and the ad spend directed to their in-app inventory. Buyers who had reduced investment due to ID deprecation returned, and new buyers were attracted by the contextual targeting capabilities.
