Posts sent to Facebook Profiles and Groups via Blog2Social display a link labeled with "Blog2Social". This is not a tag-line, but a compulsory labeling requirement for third party apps on Facebook and is automatically marked by Facebook.
When you share a post to a Facebook page a “Posted by Blog2Social” stamp will be displayed, but this stamp is only visible for you as admin or editor of this page. This labeling is not visible for the visitors of your Facebook Page.
When sharing posts on X (Twitter) the stamp is visible for you as admin or editor of this page as well as for the visitors of your profile.
For other social networks below there is no labeling, or link that will show that you’re posting with Blog2Social:
