Author Markup: Show Google and AI Who Wrote It

Google keeps telling you that experience and expertise matter. The E-E-A-T framework rewards content written by someone who knows the subject. Here is the catch: Google cannot reward a byline it cannot read as a person.

A name printed on a page is text. To a search engine, By Jane Smith could be any Jane Smith on earth, with no thread connecting that byline to a real, credentialed human. Author structured data is the thread. Google's Article guidance recommends marking each author with a Person type and, strongly, a sameAs link to a page that uniquely identifies that author. That is the machine-readable half of E-E-A-T, and Brass-SEO treats it as part of a page's authority signal, not an afterthought.

What Google's Article Guidance Says

Brass-SEO treats Google's Article structured data documentation as the spec for authorship. Google recommends marking each author with the Person type, putting only the author's name in the author.name field, and it strongly recommends adding a url or sameAs property that points to a page uniquely identifying that author.

The guidance is specific about the small stuff. When a piece has more than one author, each gets its own author field rather than a single field with two names jammed together. The author.name field holds the name and nothing else. Google names the fixes it wants and the mistakes it sees, which makes this one of the rare SEO tasks with an official answer key.

What a Plain Byline Leaves Out

Brass-SEO points out the gap a visible byline leaves. A name on the page tells a human who wrote the piece and tells Google almost nothing, because the same three words could belong to any number of people with no way to pick the right one.

E-E-A-T asks whether the author has real experience and expertise in the topic. Answering that requires connecting the byline to a specific person with a track record. A bare text name carries none of that connection. It is a label with no link to the credentials behind it. The author might be a recognized surgeon writing about surgery, and Google would have no structured way to know.

The sameAs Property Does the Disambiguation

Brass-SEO uses sameAs as the link that resolves the ambiguity. The sameAs property points from your author to authoritative profiles of the same person — a bio page, a professional profile, a published-work listing — so Google can tie the byline to one specific, verifiable identity.

This is the same mechanism Google uses across its Knowledge Graph to keep entities straight. A sameAs to a well-known profile says this author is that person, the one with these credentials and this body of work. The stronger and more authoritative the profile you point to, the clearer the identity signal. An about page on your own site is a fair start. A link to a recognized external profile of the author is stronger.

How to Write Author Markup

Brass-SEO recommends the smallest correct version first. A Person author with a name and a sameAs to one authoritative profile satisfies Google's core recommendation and gives you a base to extend later.

{
  "@context": "https://schema.org",
  "@type": "Article",
  "headline": "Your Article Title",
  "author": {
    "@type": "Person",
    "name": "Jane Smith",
    "url": "https://example.com/about/jane-smith",
    "sameAs": [
      "https://www.linkedin.com/in/janesmith",
      "https://en.wikipedia.org/wiki/Jane_Smith"
    ]
  }
}

Keep the type as Person for a human author, and reserve Organization for cases where the byline genuinely is the company. Put only the name in author.name, with no title, honorific, or publisher name mixed in. For a co-authored piece, repeat the author object for each writer. The markup should match the byline a reader sees, since Google expects the structured data to reflect the visible page.

Why AI Cares About Author Identity Too

Brass-SEO extends the same markup to AI visibility. The sameAs property is the mechanism entity systems and AI retrieval use to disambiguate people, so author markup that establishes a credentialed identity does double duty: E-E-A-T for Google, entity grounding for AI.

AI answer engines increasingly weigh whether a source is written by an identifiable expert. An author connected by sameAs to a recognized profile reads as a known entity rather than an anonymous string. Brass-SEO's piece on expert citations in AI search covers why named expertise moves the needle, and the deeper treatment lives in author bylines and E-E-A-T. The research index entry on E-E-A-T gathers the primary sources behind the framework.

Frequently Asked Questions

What author properties does Google recommend?

Google's Article structured data guidance recommends the author.name field with only the author's name, the Person type for people, and a url or sameAs pointing to a page that uniquely identifies the author, such as a bio or profile page. Google strongly recommends including the type and the url or sameAs property.

What should not go in the author.name field?

Only the author's name belongs there. Google says to leave out titles, honorifics, and the publisher's name, and to use dedicated properties for those instead. Putting a company name in author.name is a common error that muddies the author signal.

Does author markup guarantee better rankings?

No single markup guarantees rankings. Author markup makes authorship machine-readable, which supports the Experience and Expertise signals in Google's E-E-A-T framework. E-E-A-T is assessed across many signals, and structured author data is one input rather than a switch.

Do I need markup for every author?

Google says to include every author shown on the page, each in its own author field. For a single-author post, one Person entry is enough. For co-authored posts, list each writer separately instead of combining names in one field.
