E‑E‑A‑T is Google’s quality framework that evaluates a page’s Experience, Expertise, Authoritativeness, and Trustworthiness to rank content.
How to demonstrate author credentials
1. Add structured data – embed JSON‑LD with @type":"Person" or Organization and fields name, url, sameAs, jobTitle, affiliation, hasCredential. Example:
{
"@context":"https://schema.org",
"@type":"Person",
"name":"Dr. Jane Doe",
"url":"https://example.com/author/jane-doe",
"sameAs":["https://twitter.com/janedoe","https://orcid.org/0000-0002-1825-0097"],
"jobTitle":"Senior Data Scientist",
"affiliation":{"@type":"Organization","name":"Acme Analytics"},
"hasCredential":"PhD in Computer Science"
}2. Publish author bios on every by‑line – include education, years of experience, and links to verifiable profiles (LinkedIn, ORCID, Google Scholar). Keep the bio >150 words for Google’s “Helpful Content” parser.
3. Earn backlinks from high‑DR domains – aim for at least 5 referring domains with Domain Rating ≥ 60 in the last 90 days (Ahrefs). Use Ahrefs Site Explorer or SEMrush Backlink Gap to identify gaps.
4. Leverage Google Knowledge Graph API – submit verified data via the “People” endpoint; a knowledgePanel presence adds an authority signal.
5. Monitor YMYL flags – in Search Console, pages tagged “Your Money or Your Life” must have a Trust Score ≥ 70 (Google’s internal metric, visible via the “Core Web Vitals & Trust” report).
6. Show real‑world impact – embed citation metrics (e.g., 12 citations on Google Scholar) or case‑study results (e.g., 30 % conversion lift) directly on the page.
