Rod Larman is the marketing manager at The Grove Hotel in London. He discusses how social media and review sites like TripAdvisor have changed how hotels market themselves and interact with customers over the past 15 years. TripAdvisor is now the world's most influential travel site with over 260 million monthly visitors. While user reviews provide free feedback, responding can be time-consuming and scores take time to improve. However, actively working with TripAdvisor through tools like Review Express has helped The Grove's online reputation and ratings become more in line with competitors. Larman provides advice on effectively utilizing TripAdvisor to both engage customers and address any issues.
