E-E-A-T Implementation: Concrete Steps, Not Abstract Advice

Experience, Expertise, Authoritativeness, Trustworthiness — Google's Quality Rater Guidelines describe these concepts at length. But the guidelines are for human evaluators. What search systems actually measure is a set of concrete, implementable signals.

The Patent Foundation

Google's patent on author authority scoring (US Patent 9,235,627) describes how search systems assign expertise scores to content creators based on their publishing history, entity associations, and topical consistency. E-E-A-T is not subjective — it is computed.

The 12 Implementable Signals

Experience Signals (3)

1. 1First-person evidence — Content that includes specific examples, data, and outcomes from direct experience. "We implemented this for 40 clients" beats "experts recommend."
2. 2Original data or research — Publishing proprietary data, case studies, or analysis that cannot be found elsewhere.
3. 3Process documentation — Showing your methodology, not just your conclusions.

Expertise Signals (3)

1. 4Author entity completeness — Every content creator must have a Person schema with name, jobTitle, worksFor, sameAs (linking to authoritative profiles), and knowsAbout properties.
2. 5Topical consistency — Authors who publish across many unrelated topics score lower than those with deep focus on specific domains.
3. 6Credential corroboration — Claims of expertise must be verifiable through external sources.

Authoritativeness Signals (3)

1. 7Entity co-occurrence — Your brand entity appearing alongside recognized entities in your industry across third-party sources.
2. 8Citation patterns — Other sites referencing your content as a source.
3. 9SERP feature presence — Earning Knowledge Panels, featured snippets, and People Also Ask inclusions.

Trustworthiness Signals (3)

1. 10Trust page completeness — About, Contact, Privacy Policy, Terms of Service — each must be comprehensive and current.
2. 11Technical trust — HTTPS, valid SSL, no mixed content, clear cookie policies.
3. 12Review and reputation signals — Third-party reviews on recognized platforms that corroborate your brand claims.

How We Implement This

At Patnick, we score all 12 signals through our Authority Signals dimension. For each signal, we provide:

• Current score (0-100)
• Specific gaps identified
• Implementation steps with priority ranking

We then implement directly — deploying author schemas, creating trust pages, restructuring content to include first-person evidence, and building the entity associations that search systems evaluate.

The Implementation Order

Our patent-backed research shows the highest-impact implementation order:

1. 1Trust pages and technical trust (foundations)
2. 2Author entity schemas (expertise signals)
3. 3Content restructuring for first-person evidence (experience signals)
4. 4External entity building (authoritativeness signals)

Following this sequence, we typically see measurable Authority Signals dimension improvement within 45-60 days.
