Custom Built Audiences is an audience development service that creates bespoke advertising segments tailored to specific advertiser requirements. Instead of using predefined or automated audience models, these audiences are designed and constructed based on detailed criteria provided by the advertiser, including behaviors, interests, contexts, and performance goals. The service relies on large‑scale behavioral data, contextual signals, and identity resolution techniques to assemble audiences that reflect real‑world consumer activity. Audience definitions are developed through a collaborative process, allowing advertisers to translate strategic goals into precise data specifications. Custom Built Audiences is intended for organizations that require full control over how audiences are defined and composed. It supports use cases where off‑the‑shelf or algorithmically generated segments are insufficient, such as highly regulated categories, niche markets, or complex targeting strategies.
