Social media settings can be found on any of your pages at Website > [Page] > Settings > Social Media.
By default, when someone takes action on your website, a prompt to post on social media is displayed. If you do not want to encourage social sharing, uncheck the box next to “Prompt for posting” and click the Save social media settings button.
The text for the default post is automatically generated using the page name. We recommend that you edit the post. Use a clear call to action that will motivate your supporters to share the page and encourage their friends to take the same action.
