Page Level
Page-level social sharing copy only relates to the copy which social channels will use when a user copies and pastes a specific page URL into, for example, Facebook. This will be the copy that Facebook scrapes and displays on the share.
Page level social copy can be edited using both Classic Builder and Visual Builder.
If using Classic Builder, edit the page you want to update, and head to Social Sharing within the white middle navigation.
If using Visual Builder, open the page in Visual Builder and click on the screw icon in the top menu. This will open Page Settings to the right, and one of the options will be Social Sharing.
Here’s an example from our friends at The Royal Women’s Hospital Foundation.
