E-E-A-TShowing why you should be believed

Where E-E-A-T comes from#

Google employs human quality raters who evaluate search results using a published document, the Search Quality Rater Guidelines. Their ratings do not directly change rankings for any page. They are used to assess whether Google's ranking systems are producing good results, which informs how those systems are improved.

E-A-T, for expertise, authoritativeness and trustworthiness, appeared in those guidelines years ago. In December 2022 Google added a second E, for experience. The guidelines describe trust as the most important member of the family: the others contribute to it.

So E-E-A-T is best understood not as a checklist to satisfy, but as a description of what Google is trying to reward. Optimising for it means becoming, and visibly being, a source that deserves trust on the topic.

You cannot add trust to a page; you can only stop hiding the reasons for it.

The four elements in plain terms#

Not a ranking factor, but not irrelevant#

Google has said E-E-A-T itself is not a specific ranking factor. There is no E-E-A-T score. But Google has also said its systems use a mix of signals that align with E-E-A-T, especially for topics where poor information could cause harm. The honest summary: you cannot optimise E-E-A-T directly, but you can become the kind of source the signals are trying to identify.

This matters most for what the guidelines call Your Money or Your Life (YMYL) topics: health, finance, safety, legal matters and similar subjects that can significantly affect people's wellbeing. For these, the bar for trust is much higher, and anonymous or unqualified content is unlikely to be preferred.

How to demonstrate experience#

Experience is the element most generic content lacks, and the one AI-written content cannot fake. It shows in specifics: the photograph taken on the job, the measurement from the actual test, the step the manual leaves out, the mistake you made the first time and how you fixed it.

For businesses, the practical method is to put practitioners into the content process. Interview the engineer who installs the system, the chef who develops the recipe, the consultant who runs the workshops. Their detail turns a page that could have been written by anyone into one that could only have been written by you.

Make experience visible, not just present. Say who did the work and when, show the evidence, and explain the reasoning behind recommendations. A sentence such as 'we tested this on our own warehouse floor over two monsoon seasons' tells readers and raters more than a paragraph of general advice, provided it is true.

How to demonstrate expertise and authority#

• Named authors with relevant backgrounds, and author pages that describe their experience and link to their professional profiles.
• Review by qualified people for sensitive topics, with the reviewer named.
• Depth and precision: covering the nuances, exceptions and trade-offs that a non-expert would miss.
• A body of work: many good pages on a subject build more recognition than one excellent page among unrelated content; see topic clusters.
• External recognition: being cited, interviewed and linked by respected sources, as covered in link building.

How to demonstrate trust#

Trust is partly about content and partly about the organisation behind it. Readers and raters look for evidence that a real, accountable business stands behind the page and that its claims can be relied upon.

E-E-A-T for different kinds of business#

What counts as credible evidence varies by sector. For a clinic, it is qualified practitioners named and reviewing content, with clear statements of what advice is general and when to see a doctor. For a financial adviser, it is registration details, clear disclosure of how the firm is paid and careful separation of education from recommendation.

For a manufacturer, it is engineering detail, test methods, certifications and photographs of real products in real use. For a software company, it is documentation written by people who build and support the product, honest comparisons and transparent security information. For a local service business, it is the owner's name, years of practice in the area, real project photos and genuine reviews.

In each case, the question is the same: what would a sceptical, informed buyer want to see before trusting this page? Answer that, visibly, and you are doing what E-E-A-T describes.

What erodes trust quickly#

• Anonymous advice on topics where qualifications matter.
• Cosmetic 'updated' dates on pages whose content has not changed.
• Claims of results, rankings or awards that cannot be verified.
• Undisclosed affiliate links or sponsored recommendations.
• Pages that contradict each other or the business's own policies.
• Reviews that look curated, incentivised or copied.

These do not just fail to help; they actively damage credibility with readers and are exactly what quality raters are trained to notice. Removing them is often a faster win than adding new trust signals.

Audit priority pages against this list once a year, and ask someone outside the content team to do it. Familiarity makes people blind to anonymous bylines, stale dates and unsupported claims that a newcomer notices immediately.

Where to focus first#

E-E-A-T also matters beyond classic search. AI answer systems appear to favour clear, credible, well-attributed sources, which makes the same qualities relevant to generative engine optimisation. For writing standards that put this into practice, see AI content quality.
