NEW YORK—Online reviews help us decide where/what to eat, what to watch, what to buy and what to sell. They have become an integral part of who we are as consumers and business owners. They have a huge impact on how well businesses do or don’t do.

They have become the go-to way to make decisions about places we have never been and with the seemingly endless amount of options we have as consumers nowadays, they are one of the only ways to narrow down our choices as consumers. The infographic below shows how consumers read and use online review sites in numbers.

Facts: 68 percent of Millennials trust online reviews most, as opposed to 34 percent who trust television advertisements and on average they produce an uprise of 18 percent in sales. In addition, 90 percent of consumers read less than 10 reviews before forming an opinion about a business which means these decisions are being made quickly, without much hesitation.

Impact of Reviews: Online reviews have a huge impact on both businesses and consumers. The impact can be positive or negative. For example, for every star a business gets in their rating, their sales revenue will increase from approximately 5 percent to 9 percent.

Fake Reviews: A common misconception about online reviews is that they are all genuine reviews. This is simply not the case. Only 27 percent of consumers will trust an online review if they think it is authentic even though a whopping 30 percent of online reviews may be fake.
