Demonstrating E-E-A-T with structured data

Introduction: structured data does not create authority, it makes it readable

This is the misunderstanding that makes most markup useless. You add a JSON-LD block hoping it will produce credibility, and nothing happens — because markup adds nothing that is not already there.

Structured data is a translation, not a production. It translates into machine-readable form what the page already demonstrates to a human. If the page does not demonstrate it, the translation describes emptiness.

And it gets worse: a declaration the content does not support is more expensive than silence, because it is verifiable. We have a case of our own on this, and we tell it in §4.

1. What the four letters actually mean

Experience — the person writing has done the thing. An article about recovering from an attack written by someone who has handled one does not look like an article written by someone who has read about one.

Expertise — the person writing knows the field. It is demonstrated by precision and by the limits named, not by a title.

Authoritativeness — others recognise it. It is not declared, it is observed: citations, references, people picking it up.

Trustworthiness — the most important of the four for a commercial site. It is built from mundane things: who you are, how to reach you, what the terms are, what happens if something goes wrong.

Structured data covers the fourth well and the second partly. It does not touch the first or the third at all. Knowing this stops you expecting from markup what only content can do.

2. What to declare, and in what order

By decreasing return, and none of these points requires a paid tool:

Organization, once, for the site. Name, site, logos, official profiles. It is the base that connects everything else. Watch one point we measured ourselves: if the official-profiles field is declared empty, some engines confuse the brand with a namesake. Declaring it empty is worse than leaving it out.

Person for the author, with a real author page. Not a name at the bottom of an article: a page saying who the person is, what they have done, where to find them elsewhere. Without that page, the author markup points at nothing.

Article with the dates. Publication and last modification. The second matters more than the first on a subject that ages.

FAQPage only if the page genuinely contains questions. Marking up as an FAQ paragraphs that are not questions is the most widespread shortcut and the most easily detected.

Product with real price and availability on product pages. The detail is in Schema markup in JSON-LD.

3. What NEVER to declare

This section is shorter and worth more than the previous one.

• An average rating with no real reviews. It is the most tempting declaration and the riskiest.
• An author who does not exist. An invented name with an invented page is a forgery, not a technique.
• A modification date that matches no modification. Updating the date without touching the content is detectable and produces nothing.
• A price different from the one in the basket. Beyond the penalty, it is grounds for a customer complaint.

The common criterion, and it sums up the article: a structured declaration must be derivable from the page. If a human cannot verify it by reading, it does not get declared.

4. Our own case, because it is the clearest

In our own archives, a page declared an average rating and a review count while the product had no customers at all. The figure had not been invented out of malice: it came from a template filled with example values that nobody had removed.

Two lessons, and it is the second that counts:

1. a public figure you cannot derive from a fact becomes false silently — no warning, no error, just a declaration that stops being true;
2. the risk was not the penalty, it was the discovery. A visitor comparing the declared rating with the absence of reviews on the page loses trust in the rest of the site too, including the parts that are accurate.

Hence the rule we apply: we declare nothing we cannot show. Including when the declaration would suit us.

5. The protocol, on one page

• Organization declared once, with real official profiles — never an empty field
• A real author page for every byline, before marking up author
• Article with publication and last-modified dates, the second updated only on a real modification
• FAQPage only on pages that contain genuine questions
• Product with price and availability read from the source, not typed by hand
• AggregateRating only if real reviews exist — otherwise nothing
• Check the markup with the testing tool, then read the page again and ask: could a human verify this?

That last point is the one tools do not do. Markup can be technically valid and say something false.

Conclusion

E-E-A-T is not marked up, it is earned — and structured data only serves to make it readable to a machine that cannot read between the lines.

The useful work is therefore not adding JSON-LD blocks: it is having something to declare. A real author page, clear terms, a human contact, real reviews. The markup comes afterwards, and it takes ten minutes.

The test that settles it: take one of your structured declarations and look, on the page itself, for what supports it. If you cannot find it, an engine cannot either — and neither can a visitor.
