Consumer reviews have a significant influence on purchasing decisions. 70% of people trust online reviews and 82% think reviews are valuable. A one star rating increase on Yelp can mean a 5-9% increase in restaurant revenue. While shoppers trust reviews on Amazon and Best Buy more than consumer reports, 80% are concerned about fake reviews. Marketers write approximately one third of reviews, and consumers read an average of 11 reviews before purchasing. Good customer service leads to more positive reviews, while 31% of reviews need to be negative to doubt a product's quality. PR practitioners should treat reviews like social media and respond to negative reviews to protect brands from fake reviews.
