E-E-A-T

E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness) is the framework Google uses in its Search Quality Evaluator Guidelines to assess the quality and credibility of web content and the entities behind it. The four dimensions evaluate whether content demonstrates first-hand experience with the topic, subject-matter expertise appropriate to the content type, recognized authority relative to other sources in the field, and overall trustworthiness of the content, site, and creator. E-E-A-T is not a direct ranking signal (it is not an algorithm metric) but is used by Google’s quality raters to evaluate whether Google’s algorithms are surfacing high-quality content.

How it works

Google’s quality rater guidelines ask evaluators to assess pages on all four E-E-A-T dimensions when rating page quality. High E-E-A-T signals include: content created by named authors with verifiable credentials, first-person accounts or original research demonstrating direct experience, the site being cited or linked from other authoritative sources in the domain, transparent contact information and editorial policies, and accurate, up-to-date factual content. YMYL (Your Money or Your Life) topics like health, finance, legal, and safety content face the highest E-E-A-T scrutiny because low-quality information in these areas can have serious consequences.

Key facts

• Experience addition: The first ‘E’ (Experience) was added to E-A-T in December 2022, recognizing that first-hand experience from practitioners (even without formal credentials) is a valid quality signal.
• YMYL sensitivity: Finance, medical, and legal content must demonstrate the highest E-E-A-T standards; anonymous or thin content in these categories is penalized most severely.
• Author bios: Detailed author pages with credentials, publications, social profiles, and linked bios are a concrete E-E-A-T signal that publishers can implement directly.

For builders

For WikiWalls, E-E-A-T signals are especially important given the finance and builder-tool content that overlaps with YMYL categories. Practical E-E-A-T improvements include adding author bio pages with professional backgrounds, citing primary sources and data in content, keeping definitions up to date (outdated content damages trustworthiness), and building content that demonstrates genuine practical experience (case studies, tool reviews with real usage data). Building topical authority through comprehensive coverage is itself an authoritativeness signal that compounds over time.
