This is a self-funded case study using our ad testing solution. Curious about the 9 essential ingredients for creating advertising that drives profitable growth? Explore our Creative Effectiveness Playbook.
When a creative idea is distinctive enough to grab attention, spark an emotional response, and keep the brand and product benefit front and center, advertising does not need to choose between long-term brand building and short-term impact. It can do both — and our latest U.K. Campaign of the Month provides a terrific example of this.
With a strong Cubery Rating of 6.8, placing it in the top quarter of ads in the U.K., Tesco Whoosh’s “Serious Delivery” is built on a simple idea: take the everyday need for fast grocery delivery and treat it with the intensity of a cinematic action thriller. By leaning into tension, pace, and familiar genre conventions, the ad turns a functional service benefit into a highly emotional piece of creative.
Moment-by-Moment Emotional Activation
However, the approach was not without risk. The action-thriller style is not necessarily what audiences expect from Tesco, so the unfamiliar executional style could have made it harder to connect the story back to the brand. But as we’ve seen throughout a decade of creative testing, when ads move into new and unfamiliar territory, one element is especially important in ensuring commercial impact is delivered: distinctive assets.
Tesco’s delivery scooters, bags, and the prominently branded driver were woven throughout the story, ensuring the brand remained unmistakably present even as the narrative got wilder. Rather than allowing the genre to overpower Tesco Whoosh, the brand travelled with the action.
And while this strong brand presence helped embed Tesco in people’s long-term memories, the ad also gave people a clear and immediately useful takeaway. The speed and convenience of Whoosh were impossible to miss, with the urgency of the storyline dramatizing the service benefit.
That combination of attention, clear brand connection, and a compelling proposition helped the campaign deliver an exceptional Surge Index of 127, placing it in the top 10% of ads in the U.K. — reflecting its likelihood to prompt a short-term behavioral response.
The lesson: short- and long-term advertising goals do not require separate creative ideas. When entertainment, branding, and product benefit reinforce one another, a single campaign can build memories for the future while giving people a reason to act today.
