From retailers to service providers and restaurants, businesses receive a noticeable uptake if they receive positive write-ups on user-generated review sites. On average, a one-star increase on Yelp leads to a 5 to 9 percent increase in a business's revenue, according to an infographic provided by Chatterbox, a company that builds customer-engagement platforms for marketing purposes. On the flip side, one negative review can cost you 30 customers.

Clearly, online reviews are serious business. And they are becoming increasingly important: By 2017, millennials -- a group whose purchasing decisions are disproportionately impacted by customer-reviews -- will have the most spending power of any generation.

All this online negativity can be very damaging, which is why it's essential you respond to bad reviews in a prompt and appropriate fashion.
