The case shows how an FMCG campaign can work closer to shopping planning, not only on reach and clicks.

the result depends on category, creative, campaign period, and measurement methodology

Sweets are a competitive FMCG category with many impulse and routine purchase moments. Retail media helps brands appear when shoppers are choosing what to add to the next basket.

Campaign goal

The campaign promoted sweets such as bars, cookies, and chocolate. The objective was to support sales, encourage trial, and strengthen brand choice during shopping planning.

Setup

Listonic Ads placed the brand in shopping-app contexts and used formats connected with adding products to lists. The campaign focused on people already preparing grocery purchases rather than only on broad audience reach.

Result

The described campaign delivered ROAS 2.67x, generated 20,054 product additions, reached CTR 1.19%, and increased the loyalty indicator by 53%.

Why it matters

The case shows how a brand in a high-frequency category can use retail media to influence choice before the store visit. That makes the result easier to discuss in terms of planning behavior, not just ad exposure.
