E-E-A-T stands for experience, expertise, authoritativeness and trustworthiness. Google uses the concept in its search quality rater guidelines to describe what helpful, reliable content looks like, with trust as the most important part. It is not a single ranking factor, but it describes the content Google wants to reward.

The four parts
| Part | What it looks like on a site |
|---|---|
| Experience | First-hand use, photos, real projects |
| Expertise | Named authors with relevant qualifications |
| Authoritativeness | Recognition from others in the field |
| Trustworthiness | Accuracy, transparency, secure site, clear contact details |
Why it matters more in AI search
Assistants prefer sources they can attribute. Named experts, sources and transparent company details make content safer to quote.
