Retail media is easy to measure. Retail impact isn't.
For brands investing in retail media, the challenge is no longer reaching consumers, it's proving that marketing activity is driving measurable commercial growth.
While impressions, clicks and engagement can indicate campaign performance, they rarely tell the full story. Understanding whether media investment is influencing shopper behaviour and generating in-store sales remains one of the biggest challenges facing marketers today. When challenger energy drink brand Sneak, wanted to understand the real-world impact of its retail media investment, Brand Potential was tasked with finding a way to connect marketing activity directly to retail outcomes.

Turning Shopper Insights Into Sales Growth
To help answer that challenge, we used mJourney, our location intelligence platform that combines audience targeting, footfall measurement and sales attribution to provide a clearer view of how marketing influences consumer behaviour.
Working alongside Sneak, we developed a hyper-local campaign targeting key audiences including students, gamers and shift workers around Tesco stores across Northern Ireland.
By combining location intelligence with store visit and sales data, we were able to track how media exposure translated into physical store visits and ultimately commercial performance. More importantly, we were able to provide the evidence needed to demonstrate a direct link between marketing investment and sales growth.
The Results
The campaign exceeded expectations across every key measure.
18,548 store visits generated
More than 8x the original forecast
£0.53 cost per visit
20% average uplift in Tesco sales following the campaign
Up to 60% sales growth in individual stores

Data-driven growth that lasts
Perhaps most significantly, sales performance remained elevated after the campaign ended, indicating that location-based advertising can influence longer-term purchasing behaviour rather than simply driving short-term spikes in demand.
The campaign provided Sneak with clear evidence of marketing effectiveness and a stronger foundation for future retail investment decisions.
