AddThis social media icons can be enabled to allow your readers to share your website on their social media pages.
When enabled (in Site Settings > Social Media Share Buttons) AddThis buttons will appear at the bottom of each page in your site. When your reader clicks on them (on your published site) that specific page will be shared in your reader's social media post.
Alternatively, If you want to invite your readers to visit your Facebook business page or personal Facebook page, you can create a link on some text to direct them there, for example, 'Check out our FB page'.
Note: AddThis social media icons do not link to your own social media pages.
If you have a Smart or Pro site, you can create dedicated buttons to send your readers directly to your social media profiles:
• Go to 'Add a New Block'.
• Select ‘Special’.
• Scroll down to 'Social media button' and then set up the button from the page.
