Curtice Brothers is a prestige ketchup amongst world famous chefs. However, it was still relatively unknown amongst everyday consumers. To prove the unique quality of Curtice Brothers, we let the brutally honest users of Tripadvisor review the ketchup without even knowing it. We gave the worst rated restaurants on TripAdvisor bottles of Curtice Brothers and waited to see what difference the ketchup would make to their ratings. We then showed the success on geolocated digital ads and billboards close to the restaurants. The result: every restaurant reported an increase of at least half a star rating.
