What actually makes content feel credible—to search engines and AI systems.
EEAT Ranker documents how Experience, Expertise, Authority, and Trust signals appear on real pages — and whether strengthening them changes how content performs in search and AI-generated answers.
exists
Credibility signals are becoming part of how content gets discovered.
Search engines and AI systems both weight credibility when deciding what to surface. Author attribution, credential clarity, source density, and brand trust all appear in that assessment. EEAT Ranker tests how much each one matters.
These signals are often subtle. They appear to matter more as AI systems become part of how people find and verify information — not just search engines.
questions
Open questions — tested against real pages.
Each field note addresses one of these directly, with measured outcomes where available.
Do stronger trust signals increase citation frequency in LLM-generated answers?
Which EEAT elements produce measurable retrieval lift vs cosmetic change?
How do AI systems interpret credibility signals compared to traditional search ranking?
Can targeted edits to a single page change its AI visibility within weeks?
tests work
Real pages. Isolated changes. Measured outcomes.
Existing published content — live URLs, real traffic, real signals.
Author attribution, credential clarity, source density, or claim specificity — one variable per test.
A fixed prompt set run via LLMin8 across ChatGPT, Perplexity, Claude, and Gemini before and after the change.
Findings documented including null results — when a credibility change produces no measurable retrieval effect.
may become
A public record — and eventually a diagnostic tool.
Patterns, examples, and edge cases — documented openly as experiments run. Over time this work may become a lightweight tool for auditing EEAT signals on any page.
For now: field notes, raw findings, and the occasional result that doesn’t fit the expected pattern.

“Trust is rarely one large change. It’s usually a collection of small signals — noticed or ignored.”EEAT Ranker is finding out which ones actually move the needle.
