E-E-A-T is not a single signal — it's an aggregation of dozens of on-page and off-page proxies.
E-E-A-T is not a direct ranking factor; it influences many ranking factors via algorithmic proxies. Below is the working checklist of what those proxies actually are.
On-Page E-E-A-T Signals
Content Quality Indicators
Comprehensive, well-researched content that fully answers the query.
Clear, authoritative writing style — confident, sourced, no fluff.
Proper citation of sources, with links to primary references.
Regular content updates with visible "last updated" dates.
Original insights and analysis — not just rephrased competitor content.
Author and Expertise Signals
Detailed author bios with credentials and links to other published work.
Dedicated author pages with comprehensive information.
Low — lacking expertise or experience, incomplete.
Medium — adequate, neither beneficial nor harmful, meets baseline.
High — beneficial, well-demonstrated expertise, strong trust signals.
Highest — exceptionally beneficial, recognised industry leader.
