Consumers lose trust – in a big way – when a product or service doesn’t have a 4- or 5-star rating in online reviews, according to a new survey. Some products and services live or die by the online reviews they get. There is a massive drop in trust between a 4-star and a 3-star rating – which can result in lost revenue for those companies. The question: What is the minimum star rating (out of five) a product or service needs for consumers in the consideration stage of a purchase decision? Digital marketing agency Go Fish Digital surveyed 1,070 people about online reviews to find out how much they influence purchasing decisions.
