Objective

Attain wanted to scale CTV acquisition while maintaining CPA efficiency against internal benchmarks and overall campaign performance.

Challenge

As Attain looked to scale, the team needed a way to reach net-new households without sacrificing CPA efficiency. Broad targeting can add reach, but it can also dilute performance, so Attain focused on a more controlled expansion strategy.

Approach

Attain and tvScientific by Pinterest shifted from a steady-state approach to a deliberate growth plan built around audience strategy and staged scaling.

A key lever was Lookalike Segments, generated from tvScientific by Pinterest's proprietary household graph (or household ID) and available directly within the UI. This helped Attain reach new households that resemble high-value users, while keeping expansion more controlled than broad targeting.

Alongside lookalikes, Attain rounded out the strategy with retargeting and layered audience targeting, pairing Pinterest finance interest audiences with demographic cohorts.

As performance held, Attain scaled investment in steps and continued optimizing creative and budget allocation toward the audiences delivering the strongest results.

Why it worked

A staged approach reduced risk. Stepwise increases allowed Attain to scale while monitoring efficiency and volume.

Multi-Approach

A diversified audience mix improved stability. Lookalikes, retargeting, and layered audiences helped Attain avoid over-reliance on a single approach as budgets grew.
