Case Study: Yakult launches a confident cross-market campaign with Kantar Marketplace ad testing

When pivoting from country-led advertising to a single cross-market campaign, Yakult turned to ad testing insights from Link Now and Link Express on Kantar Marketplace

The probiotic drink brand Yakult faced the challenge of validating and launching a new cross-market campaign, "Little bottle on a big mission," across several European countries. They needed to act quickly to determine if the creative would resonate internationally and transition from a country-led advertising approach with confidence. To address this, they turned to vendor Kantar for ad testing using the LINK with neuroscience solution on Kantar Marketplace.

Kantar’s solution provided a standardized approach with robust, multi-country insights, allowing Yakult to assess the creative’s potential in just four days. The ad pre-test confirmed the campaign’s viability across all markets and its ability to drive both brand equity and sales. As a result, Yakult was able to confidently launch a consistent, effective European campaign to grow the brand.
