Should I add my social media links to my booth?

If you would like attendees to have access to your social media, then yes.

This is entirely up to you. It is not mandatory, however, if you would like attendees to have access to your social media when they visit your booth, then you should add them. You can do this from the "My Organization" area of your company profile.  The more information you provide on your booth, the more the candidate can educate themselves about your organization.
