The campaign was rigorously tested, and changes to creative were made in real time. The campaign generated critical insights into Walgreens’ client base and proved that each market had different requirements for success. The creative units that showed an animated video with a coupon for allergy medicine followed by messaging around high pollen counts performed the best in Atlanta, Dallas, Houston, New York and Philadelphia; while in Boston, LA, San Francisco and Minneapolis St. Paul, Stories that first informed that pollen counts were high followed by a coupon, performed best.
Clinch created 160 creative variations, personalized by location, and tested a Story featuring the coupon value and a Story featuring the “high pollen” message. The click through rate was 276% higher than previous allergy-related campaigns at a cost per person reached 41% lower and a cost per click 64% lower.
