Entity SEO for experts: authors, credentials and sources AI trusts

Entity SEO is making it unambiguous to search engines and AI systems who you are, what you know and which pages are yours, then backing that with sources other people wrote. For an expert the work is mostly editorial: real author pages, one consistent name, matching markup, independent mentions and visible dates. None of it is a switch.

What is an entity, and why does it matter for AI search?

An entity is a distinct person, organisation, place or thing that a system can identify and link to other things, rather than a string of words that happens to match. Google's 2012 announcement of its Knowledge Graph (opens in a new tab)^[10] summed up the shift as "things, not strings".

Names collide: two practitioners can share one, and a quote can end up credited to the wrong person. A system that cannot tell which "you" a page describes has a weak basis for attributing an answer to you.

Google's page on AI features (opens in a new tab)^[7] states: "There's also no special schema.org structured data that you need to add." That covers Google's own AI features only; this article could not verify how other assistants choose sources. Treat everything below as practice that makes you easier to identify and check, not a recipe for being cited. It is one part of generative engine optimisation for expert businesses.

Is E-E-A-T a ranking factor you can switch on?

No. E-E-A-T stands for experience, expertise, authoritativeness and trust. It comes from Google's Search Quality Rater Guidelines (opens in a new tab)^[2], the document human raters use to judge page quality (the 11 September 2025 edition was the one served at that address on 22 October 2026). The guidelines say "No single rating can directly impact how a particular webpage, website, or result appears in Google Search".

Google's own guidance on helpful content (opens in a new tab)^[1] agrees: "E-E-A-T itself isn't a specific ranking factor". It adds that its systems give more weight to strong E-E-A-T on health, financial stability and safety topics, so on those topics strong E-E-A-T counts for more.

Trust sits at the centre. "Of these aspects, trust is most important," says the same page, and the rater guidelines call it "the most important member of the E-E-A-T family", because an untrustworthy page has low E-E-A-T however experienced it looks.

The guidelines name three places raters look for evidence: what a site or creator says about themselves (an About page or profile), what others say about them (independent references), and what is visible on the page itself. Everything below maps onto them.

What does the whole job look like?

The sections after the table give the reasoning and sources.

What should an author page say?

Google's helpful content guidance asks: "Do bylines lead to further information about the author or authors involved". It adds: "We strongly encourage adding accurate authorship information" and "avoid using deceptive authorship information". So every article an expert publishes needs a byline that links to a page about the person.

That page should carry:

• Your full name as you publish professionally, and your current role.
• What you do and who you do it for, in plain sentences.
• Credentials, each with a way to check it: a licence register entry, the awarding institution, a membership body listing.
• The experience behind your authority on the topic, limited to what can be shown.
• Links to your profiles and to places others have featured you, a contact route and a reviewed date.

For professionals who publish, the rater guidelines say "Educational degrees, peer validation, expert co-authors, and citations" can be evidence of positive reputation. They also tell raters to base E-E-A-T on the content, reputation research and verifiable credentials rather than claims of being an expert, and to rate overstated claims Low. A short, true bio does more for you than a long, inflated one.

This blog is built to work this way: named authors, each with an author page marked up as a Person, and profile links added only once an author supplies them. The bios currently state each author's role at Plandora and nothing more, which is the right default until there is more that can be shown.

How do you keep your name consistent everywhere?

Pick one form of your name and your business name, write it down, and use it on your byline, author page, profiles, association directories and conference bios. Decide once whether you use a title such as Dr. If a name has changed, keep the earlier one findable on your author page and link the two.

Then link in both directions: your author page points to each profile, and each profile points back to your site. Any system reconciling records by name has an easier job when the names agree and the links confirm it.

What markup should you add, and what does it do?

Three pieces cover most expert sites.

1. Article markup with an author. Google's Article documentation (opens in a new tab)^[5] says to "only specify the name of the author" in the name property and "Don't add any other piece of information". Use the Person type for people and Organization for organisations, put job titles in jobTitle and list each author separately.
2. Person markup on the author page. schema.org's Person type (opens in a new tab)^[8] has properties for name, jobTitle, worksFor, url, knowsAbout, alumniOf, hasCredential and sameAs. The sameAs property (opens in a new tab)^[9] is defined as a "URL of a reference Web page that unambiguously indicates the item's identity", such as a Wikipedia page, a Wikidata entry or an official website. Use it for profiles that are verifiably yours.
3. Organization markup on the About page. Google's organization guidance (opens in a new tab)^[6] lists many recommended properties, including name, url, logo and sameAs; none is required.

Markup states what you claim; it does not prove it. Google's structured data introduction (opens in a new tab)^[4] is blunt about the limit: "don't add structured data about information that is not visible to the user, even if the information is accurate". If hasCredential appears in your markup, the credential must appear on the page. For how crawlers read markup alongside the visible page, see how AI crawlers read your website.

What counts as third-party corroboration?

The rater guidelines tell raters to look for "independent reviews, references, news articles, and other sources of credible information" about a site or creator. In practice:

• A listing in a professional body or licensing directory that confirms your membership or licence.
• Conference programmes and speaker pages that name you.
• Interviews and podcasts whose show notes name you and link to you.
• Trade press that quotes you, and co-authored papers or guides.

Each should name you as you name yourself and, where possible, link to your author page. The guidelines also treat endorsements from a party with a clear conflict of interest, such as a manufacturer reviewing its own product or a paid influencer, as less trustworthy. Corroboration you wrote or paid for will weigh less.

Having little of it yet isn't in itself a sign of low quality: for small websites the guidelines say little or no reputation information is "not indicative of high or low quality". It is a reason to start earning sources.

Should you create a Wikipedia or Wikidata entry?

Probably not yet, and not yourself. Wikipedia's notability guideline (opens in a new tab)^[11] presumes a topic suits its own article when it has "significant coverage in reliable sources that are independent of the subject". Independent excludes works by the subject or anyone affiliated with it: the subject's own website, press releases, advertising and autobiographies. Notability "does not necessarily depend on things such as fame, importance, or popularity", so it measures coverage, not achievement. Topics that fail are not kept as separate articles, and those with nowhere to merge are "generally deleted".

Wikipedia's conflict of interest guidance (opens in a new tab)^[12] says you should "generally refrain from creating articles about yourself", and that paid editing must be disclosed. If an article about you or your business is wrong, propose a sourced correction on its talk page instead of editing directly.

Wikidata's notability criteria (opens in a new tab)^[13] differ: an item is acceptable if, among other routes, it refers to a "clearly identifiable conceptual or material entity" that can be described with "serious and publicly available references". Whether your references count as serious is a community judgement, so treat an item as an outcome of your corroboration, not a step in building it.

Why keep dates and sources visible?

A published date, a reviewed date and primary sources linked beside the claims they support let a reader, or any system retrieving the page, see how fresh a statement is and where it came from. If you add datePublished or dateModified to markup, show the dates on the page too, by the same match-the-page rule.

This blog's article format has fields for named authors, published, updated and reviewed dates, and an accessed date for every source. Writing each claim so it stands alone with its source is covered in answer-first writing for people and AI.

What should you not do?

Invent authors or inflate credentials. AI-generated headshots, made-up names and false credentials are the fabricated creator profiles Google's guidance calls deception. The rater guidelines call deceptive information about a website or content creator "a strong reason for the Lowest rating", and an inflated bio carries more risk on health, finance and safety topics, where Google weighs E-E-A-T more heavily.

Publish at scale to look authoritative. Google's spam policies (opens in a new tab)^[3] define it: "Scaled content abuse is when many pages are generated for the primary purpose of manipulating search rankings and not helping users." The policy applies "no matter how it's created" and lists generating many pages with AI tools without adding value for users as one example. An expert's practical risk is putting their name on many pages they have not written or reviewed: scaled content and deceptive authorship at once.

Manufacture corroboration. Bought reviews, invented citations and undisclosed paid Wikipedia editing invite the conflict-of-interest discount, or worse.

Where does a Digital Mind fit?

A Digital Mind on your site answers visitors from the knowledge and instructions you approve. It is not the human expert and should not be presented as one, so the named person, credentials and sources stay on your own pages, where a reader or an AI system decides whether to believe you.
