Running a business without a social media presence is a mistake.
It's harder to spread the word about your business.
You can share testimonials online, and your customers will have comments of their own to share. Online, their comments will be seen by possibly hundreds of their friends.
You're in the dark about your reputation.
What are people saying about you? If you have social media and are monitoring it correctly, you can see - and respond to - both the positive and negative experiences of your customers.
It's harder and more expensive to tell people about new products.
Using social media is far less expensive than traditional advertising. One post has the potential to be seen by hundreds of people - for free.
