Case Study: Graza boosts marketing efficiency with WorkMagic

Graza boosts Meta performance 2.7x with WorkMagic

Graza, a fast-growing olive oil brand, needed to prove the true effectiveness of its Meta Ads before increasing its investment. Their existing last-click attribution models could not isolate the actual impact Meta was driving. To solve this, they partnered with WorkMagic to implement a geo lift test.

WorkMagic used machine learning to design a geo lift test that accurately measured Meta's incremental impact. The test revealed Meta's true contribution was 2.7 times higher than last-click reported. This clarity gave Graza the confidence to scale its Meta spend by nearly 60%, resulting in a 106% increase in Meta-attributed sales, a 9% improvement in POAS, and a 14% reduction in CAC.
