Adding "social media" links to a site will help your visitors to stay connected to your business. If you can get them to like you on Facebook or follow you on Twitter, every time you make a new announcement, or update your website, they might see it on their feed and come back or better yet, retweet that or share that on their timeline.
Follow these simple steps:
From your Admin panel select Store Settings > General > Store Preferences > Social Media > Save 👍🏻
Now add the widget to a layout and choose what to show
Now check it out on the storefront.
