Expertise

The E-E-A-T dimension covering the content creator’s knowledge and skill in the topic. Signals include a real author byline (not “Admin”), stated credentials and bio, thorough depth, and Person schema tying the author to a real entity. Expertise can be formal (a doctor) or everyday (a genuine hobbyist), as long as it’s demonstrated and attributable.
