Referrals are some of the best ways to get new clients or customers for many businesses. That simple "hey, this person or service was really good from this business, you should go to them" is a great way for people to gain business.

From the late 90's to the early 2000's it was all about how good your website was and how well you engaged with your audience via blog comments and message boards. Now it's all about how well you can engage with folks on social media, how can you captivate your audience, how can you make them stop and look at the picture or video on their feed? More importantly, how quickly can they share your content to their friends?
