Author byline schema lacks credential signals (E-E-A-T)

E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness) is the framework Google and AI answer engines use to judge whether content was written by someone qualified to write it. This check found your page names an author in its schema, but that author's Person entity carries no credential signals: no jobTitle, hasCredential (a qualification or certification), alumniOf, sameAs profile links, or knowsAbout topics. The byline is essentially just a name with nothing backing it up. AI answer engines and Google's E-E-A-T weighting both reward content where the author's expertise can actually be demonstrated, not just claimed. A named byline with no supporting credentials is a weak signal on any content, and it matters even more for advice-driven or YMYL (Your Money or Your Life) topics like health, finance or legal content, where credibility directly affects whether AI systems will cite the page. Your developer needs about 30-45 minutes per author. Enrich the author's Person schema with jobTitle, hasCredential for any relevant qualifications, alumniOf for their education, sameAs links to their LinkedIn or professional profile, and knowsAbout listing their subject areas, so the byline is backed by verifiable facts rather than just a name.
