If you’re a business owner, you probably already know the power of a bad review. But did you know that in our mobile-crazed ecosystem, reviews are more important than ever?

Sometimes reviews count for even more than the word of a friend, with 4/5 consumers changing their mind about a recommended purchase after consulting reviews. It doesn’t even take any words to have an impact, with a Harvard Business Review study noting that additional stars on Yelp ratings translate to as much as 5-9% increase in revenue.
