TripAdvisor awards top-rated hospitality businesses the Certificate of Excellence annually. The TripAdvisor Certificate of Excellence is one of three prestigious awards that give bragging rights to hotels, restaurants, and attractions. Displaying a TripAdvisor Certificate of Excellence can improve walk-in business and improve your online listings. Many of the factors in TripAdvisor rankings are determined by a secret, proprietary algorithm (generally involving quantity, recency, and quality of reviews), but we know that asking your happy customers to leave you TripAdvisor reviews you’ll be well on your way to earning this award.
