E-E-A-T

advancedwidespread

E-E-A-T is Google's four criteria for assessing content credibility: whether it is backed by experience, expertise, authoritativeness, and trustworthiness.

In plain terms

If your neighbor and a pediatrician practicing for twenty years both give advice for your feverish child, you do not trust them equally. You check who is speaking, where they know it from, what others think of them, and whether they have deceived you before. E-E-A-T describes this same sound judgment for websites.

The four letters stand for four questions. Experience: has the author tried what they write about? Expertise: do they understand the topic? Authority: do others cite them on the subject? Trustworthiness: is the site accurate, transparent, and honest? According to Google, trustworthiness is the most important, with the other three supporting it.

E-E-A-T is not a program or a score, but a set of criteria. Google's human quality raters use it to judge whether search results are good, and website creators use it as a compass.

In the AI era, this matters even more. Anyone can have text generated in moments today, so the content that stands out is that backed by a real person, real experience, and verifiable sources.

How it works

By its own account, Google provides detailed guidelines to roughly 16,000 external, contracted human evaluators, who use them to review search results and websites.
The evaluator checks who stands behind the site: whether there is a named author, contact details, an imprint, and what independent sources say about the site.
It assesses the four criteria and adjusts the strictness to the topic. The bar is much higher for health, financial, and legal matters than for a cookie recipe.
Evaluations do not directly change the ranking of any single page. Google uses them to verify whether its ranking algorithms are working correctly.
Algorithms monitor signals that align with these criteria. An example is whether credible sites link to the content.

An everyday example

You search to see whether two medications can be taken together. Among the top results are articles from a hospital, a pharmacists' chamber or a doctor, not an anonymous blog. This is partly because, on such topics, Google gives priority to pages that signal credibility.

A common misconception

MythE-E-A-T is a score calculated by Google for every page, which can be boosted with a few technical tricks.

In realityThere is no such score, and E-E-A-T is not a ranking factor in itself. It is a framework used by human evaluators, which algorithms only approximate through various signals.

Limits and risks

The appearance of authenticity can be faked: with a fabricated author biography and AI-generated 'expert' text, the system can be deceived for a time.
Algorithms infer only from indirect signals, so it happens that a page of an excellent but unknown specialist ranks lower than that of a major brand.
This is Google's own set of criteria, not a standard or a law. Other search engines and AI assistants may weigh things differently.
A good ranking is no guarantee of truth; you should also check the source.

Similar, but not the same

Search Engine Optimization (SEO) – SEO is the collective term for all tasks that help a page achieve better ranking, while E-E-A-T within it describes only the credibility aspects.
YMYL-tartalom – YMYL refers to topics (health, money, safety) where errors can cause serious harm, while E-E-A-T is the standard applied especially strictly to these.
PageRank – PageRank is a value calculated mechanically from links, while E-E-A-T is a non-numerical framework based on human assessment.

A brief history

Google introduced the E-A-T triad (Expertise, Authoritativeness, Trustworthiness) in 2014 in guidelines for search quality raters. In December 2022, a fourth criterion, Experience, was added, making it E-E-A-T.

Where things stand

By the end of 2026, E-E-A-T remains a fundamental concept in search marketing, and Google's repeatedly updated evaluator guidelines continue to be built on it. The industry still regards it as a reference point in the era of AI search engines and AI agents, as they too must select reliable sources.
