What Is E-E-A-T?

E-E-A-T (Experience, Expertise, Authoritativeness, and Trustworthiness) is a concept Google uses in its Search Quality Rater Guidelines to evaluate the quality of content. In 2022, Google added “Experience” to what was previously known as E-A-T, expanding it into E-E-A-T. While it is not an algorithm that directly determines search rankings, it is explicitly laid out in the guidelines Google’s quality raters use to judge whether content is trustworthy for users.

The Four Elements of E-E-A-T

The four elements are as follows: “Experience” refers to whether the author has firsthand experience with the topic; “Expertise” refers to whether the author has in-depth knowledge and skill in the field; “Authoritativeness” refers to how recognized and respected a site or author is within its industry; and “Trustworthiness” refers to whether the content and the site behind it can be relied upon. The addition of “Experience” is particularly telling — it signals a shift toward valuing firsthand, primary-source content over secondary content that simply summarizes what’s already available online.

Why So Many E-E-A-T Articles End Up Being Commodity Content

That said, simply following the same keywords and structure to “address” E-E-A-T often produces content indistinguishable from countless other explainer articles — the very definition of commodity content. Explainers on E-E-A-T itself are already abundant online, and the more writers approach it from the same angle, the more each piece gets lost in the crowd. That’s exactly why it matters who is writing, and what experience they’re drawing on.

What “Experience” Means to Delta Tribe

At Delta Tribe, based in Tama, Tokyo, we’ve worked on web production, systems development, multilingual localization, and e-commerce operations support across a wide range of industries and project scales. We believe this kind of hands-on experience is the very essence of E-E-A-T. Take CMS selection as an example: the real issues only surface once you’ve actually built and run a site — something no catalog-style comparison article can capture. Page speed, ease of updates, garbled text or cultural nuances in multilingual implementations — these are lessons learned in the field, not things anyone can simply write about secondhand.

Trustworthiness Comes from Relationships, Not Just Reputation

As for authoritativeness and trustworthiness, we’ve always prioritized the relationships we build with clients and partners over chasing external recognition. The idea of “kyōzon kyōei” (mutual coexistence and shared prosperity) embedded in our company name reflects a commitment to walking alongside clients over the long term, rather than treating each project as a one-off transaction. We believe strong citations and word of mouth are a natural byproduct of good work — not something to be engineered.

Conclusion: E-E-A-T Is Not a Technique, It’s a Practice

Because this is such an easy topic to turn into generic commentary, we believe the real shortcut to E-E-A-T is putting into words the knowledge you’ve gained by actually doing the work, rather than stopping at general explanations. As a production company, part of our role is helping clients translate their own experience into their website and content. It’s not enough to explain the terminology in a guideline — the real question is how to embody it in day-to-day production work. That’s the practice we intend to keep sharing on this blog.
