It's become commonplace to find social media icons on business websites that link to social networks where the company has a presence.
Facebook becomes the personality of your business where visitors can find out more about the people who make it up. Twitter can be a news ticker that keeps followers informed about your company on an up to the minute basis. LinkedIn is where professional connections are made, and Pinterest brings story of your company to life in photos and videos. (And Google+ will help you get found in search!)
What does all that add up to? A more complete composite of who you are and what you do that breeds familiarly, enhances likeability and garners trust. And we all know that people want to do business with companies they know, like and trust. Adding social media icons is a path to make that happen.
Social media icons that link to social networks is one way to add social depth. Social sharing icons such as Google’s +1 Button, Facebook’s Like Button, Twitter’s Retweet Button, and Pinterest's Pin it button are another.
These make it easier for visitors to share you content with friends. There's no marketing like word of mouth and this is a great way to put your business in front of others, and by friends and family members they already trust.
