E-E-A-T Quality Signals

๐Ÿ…
Medical website
"After the 2018 Medic Update, medical sites without author attribution and sources lost up to 90% of traffic. Google started seriously evaluating who writes, what they write, and whether it can be trusted."
๐Ÿ“Œ E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness) โ€” a system for evaluating the quality of authors and sites. Especially critical for YMYL topics (health, finance, law).

E-E-A-T Breakdown

LetterMeaningHow to improve
E โ€” ExperienceAuthor's personal experience with the topicReal cases, photos, results
E โ€” ExpertiseProfessional knowledgeAuthor pages, credentials, education
A โ€” AuthorityIndustry recognitionMentions, backlinks, citations
T โ€” TrustReliability and honestyHTTPS, contacts, policies, reviews
E-E-A-T checklist:

โ˜ Author page with biography
โ˜ Links to credentials and social profiles
โ˜ Sources and citations in content
โ˜ Company contacts and address
โ˜ Reviews (Google, Trustpilot, etc.)
โ˜ HTTPS and privacy policy
๐ŸŽฏ Priority: Trustworthiness is the foundation of E-E-A-T. Without trust, other signals are weaker. Start with HTTPS, real contacts, and transparent policies.
๐ŸŽฎ Test yourself: arrange E-E-A-T levels by priority.
