Proving Pinterest’s True Contribution: How Thirdlove Scaled New Customer Acquisition

How much of Pinterest’s reported performance was truly incremental?

When Thirdlove launched a new line, Pinterest Performance+ helped the brand reach new customers while continuing to engage existing ones. But platform reporting alone could not show how much incremental revenue was actually caused by the campaigns. Working with Measured, Thirdlove isolated incremental lift from conversions that may have happened anyway, gaining a clearer view of Pinterest’s role in customer acquisition and a stronger basis for evaluating performance than attribution alone.

Using Incrementality Insights to Guide Media Budget Allocation

The results showed Pinterest delivered iROAS more than 2x Measured’s benchmark, with incremental sales coming from both new and existing customers. More importantly, the analysis gave Thirdlove evidence it could use for the next investment decision: was Pinterest driving enough incremental growth to justify scaling spend and shifting more toward acquisition?
