# E-E-A-T

> E-E-A-T is not a specific ranking factor. It names aspects of helpful content (experience, expertise, authoritativeness, trustworthiness) that Google's systems identify through a mix of signals. Trust matters most, and quality raters' assessments are not used directly in ranking.

## Definition

> **Officially documented:**
> Google's systems "identify a mix of factors that can help determine which content demonstrates aspects of experience, expertise, authoritativeness, and trustworthiness, or what we call E-E-A-T. Of these aspects, trust is most important."

## What it is not

> **Officially documented:**
> "While E-E-A-T itself isn't a specific ranking factor, using a mix of factors that can identify content with good E-E-A-T is useful."
>
> Sources: [Google Search Central: Creating helpful, reliable, people-first content](https://developers.google.com/search/docs/fundamentals/creating-helpful-content)

There is no E-E-A-T score to measure or optimize directly. Claims of a single E-E-A-T signal, such as an author bio, a badge or a schema property, go beyond what Google documents.

## YMYL topics

> **Officially documented:**
> Google's systems give "even more weight to content that aligns with strong E-E-A-T" for Your Money or Your Life (YMYL) topics. These are topics that could significantly affect people's health, financial stability or safety, or the welfare of society.

## Quality raters

> **Officially documented:**
> Search quality raters are trained to judge whether content has strong E-E-A-T, using the search quality rater guidelines. Google says raters have no control over how pages rank. "Rater data is not used directly in our ranking algorithms." Google compares it to a restaurant's feedback cards.

The rater guidelines are therefore a useful self-assessment tool, not a ranking specification.

## Not established

- Whether, or how, AI answer engines other than Google weigh comparable signals when choosing sources. Their documentation does not use the term.
