Authorship answers a question readers often ask without thinking about it: Who is behind this content? On a company website, the answer usually has two levels: the person who wrote a piece and the company that publishes it. Google names both in the guidelines for its quality raters, people who assess the quality of web pages on Google’s behalf: it should be clear who is responsible for a website and who created the content on a page. For a company’s homepage or a product page, the company itself counts as the creator there; for articles with named authors, it is those authors.
How authorship becomes visible
In its guidance on creating helpful, reliable, people-first content, Google asks whether it is self-evident to visitors who authored the content and whether bylines lead to background information about the authors and the topics they cover. Google strongly encourages adding accurate authorship information, such as bylines where readers might expect them. Authorship shows mainly in three places:
- Byline: the name and role right on the piece, such as “By Jane Example, Head of Engineering at Example GmbH.”
- Author page: a separate page for each person, with their background, qualifications, hands-on experience, and the topics they write about. The byline links to it.
- Company information: an About page, the legal notice, and company details that read the same everywhere. Keeping the name, address, and description identical on profiles and in directories as well is part of brand fact consistency.
Besides the name, a byline often shows the date of publication or of the last update. How such dates are signaled to people and machines is a matter of content freshness.
Authorship in structured data
What the byline shows people, structured data records for machines: information in the page’s code, often simply called markup. The schema.org vocabulary provides two properties for articles and other content: author for the person or organization that wrote the content, and publisher for the person or organization that publishes it. An author can be described like this, with the name of each entry before the colon and its value after it:
- @type: Person (states what is being described)
- name: Jane Example
- jobTitle: Head of Engineering
- url: the address of her author page
- worksFor: Example GmbH
The publisher entry names the company that publishes the piece, with the type Organization, its name, and the address of the website. If the website already contains Organization markup, the entry can refer to it through its fixed identifier (@id). Google sets out a few rules for author information: every person shown as an author on the page belongs in the markup, each in their own author field. The name property holds only the name—no job title, honorifics such as “Dr.,” or phrases like “posted by.” People get the type Person, companies the type Organization. Like all structured data, the markup has to match what is visible on the page.
E-E-A-T: Google’s concept of trustworthy content
E-E-A-T stands for experience, expertise, authoritativeness, and trustworthiness: first-hand experience, the knowledge a topic requires, recognition as a go-to source for it, and trust—whether content is accurate, honest, and reliable. Google uses it to describe qualities of helpful, reliable content. According to Google, trust matters most; the other three aspects contribute to it, and content doesn’t have to demonstrate all of them. Google says E-E-A-T itself is not a single factor that its systems measure; instead, they rely on a mix of factors that point to these qualities. Google adds that clearly indicating who created a piece of content likely aligns with the concepts of E-E-A-T.
E-E-A-T is explained in detail in the guidelines for Google’s quality raters. One of the things their assessment can draw on is what a website or a person says about themselves, for example on an About page or a profile page. According to Google, raters’ judgments don’t feed directly into its systems; they help Google check whether those systems work as intended.
What authorship means for GEO
For AI Overviews and AI Mode, Google points to its guidance on helpful, reliable, people-first content, which includes the recommendation on author information. Perplexity gives some cited websites a source label; most websites carry none. When assigning labels, Perplexity checks, among other things, whether a website says who wrote each piece; whether the labels affect which sources go into an answer, Perplexity does not say. No AI provider documents author information as something that determines which sources an AI system selects or cites.
The case for authorship is still tangible. Readers can see who is behind a piece of content and judge their qualifications. Content becomes clearly attributable for people and machines alike: the byline, the author page, and the markup connect a piece to a person and that person to the company, so both can become recognizable as entities. And the effort is small, because the byline and the link to the author page are usually set up once in the article template and then appear on every article.
