Author bio
Also called: author box, byline, author page, author byline
An author bio is a short on-page blurb, usually near the byline or at the end of an article, that names the writer and states their relevant credentials, experience, and focus areas. It signals to readers and search engines who created the content, which supports E-E-A-T.
Google’s guidance on people-first content frames three “Who” self-assessment questions: is it self-evident who authored the content, do pages carry a byline where one is expected, and do those bylines lead to further information about the author. An author bio answers all three in one block. Google says it “strongly encourage[s] adding accurate authorship information, such as bylines to content where readers might expect it.”
What a bio needs to earn trust
A useful bio does more than print a name. It states the writer’s relevant qualifications, links to a dedicated author page, and often links out to profiles that corroborate those claims (a professional body, published work, LinkedIn). For YMYL topics (health, finance, legal), the credential line carries the most weight, because someone assessing trust wants to see the person is actually qualified to advise.
Pair the visible bio with Person schema. In Article structured data, Google recommends the author property use the Person type with a real name plus a url or sameAs pointing to the author’s page. Keep author.name clean: no job title, no honorific, no publisher name mixed in.
A bio that signals expertise:
Dr. Jane Okoro, DVM, has practiced small-animal medicine for 12 years. She writes our clinical guides and reviews all pet-health content. [Full profile]
Skip the empty version (“Jane loves coffee and long walks”). It fills space without demonstrating any expertise, so it does nothing for readers or raters.
How it affects your traffic
Author bios are an on-page E-E-A-T signal you control directly, and thin or missing bylines are one of the most common gaps we flag in an audit. Adding credentialed bios, dedicated author pages, and matching Person schema strengthens how both Google and AI answer engines attribute your content, which matters more as they surface named experts. Our On-Page SEO work builds this authorship layer into the page templates, so trust signals ship with every article instead of being bolted on later.
