Are Personas Good for EAT?

The author page and social profiles can be used to establish a person as an expert. If their LinkedIn doesn't really support whether that's fine, if they have links to pages that are certifications or scholarly papers they've written, definitely put those in too. But you're not looking to establish that they're an expert through LinkedIn. You're just trying toestablish that they're human. They're real person. That's the main component that this is an actual person.
