When you create a social app, you can choose which URL will be shared in the posts from participants.
1. Go to Marketing Activities.
2. Select the app, and click Edit Draft.
3. In the social app editor, go to App Settings and then Advanced Options.
4. Select the URL the social posts links to.
Share Posts can link to three places:
Referring Page: The page that contains the app.
Other Landing Page: A different Marketo landing page from the ones in the drop-down.
External URL: A non-Marketo landing page.
