Why does a bio page matter more for a health practice?
Google’s own guidance on helpful content introduces E-E-A-T (experience, expertise, authoritativeness and trustworthiness) and then says plainly: "Of these aspects, trust is most important."1 It adds that its systems give "even more weight" to content showing strong E-E-A-T on topics that could affect people’s health, financial stability or safety.1 A chiropractor’s page about back pain, a naturopath’s page about fatigue and a dentist’s page about implants all sit in that category.
The same guidance asks site owners three questions about each page: who created it, how, and why. On the first, it asks whether pages carry a byline where one might be expected and whether "bylines lead to further information about the author".1 That further information is the bio page. Without one, the byline is a name with nothing behind it.
One clarification, because it gets misquoted. Google employs search quality raters who score results against a long public handbook, and that handbook is where most of the E-E-A-T detail lives.2 Google states that rater data "is not used directly in our ranking algorithms".1 The handbook describes what Google is trying to reward. It is not a checklist that moves rankings by itself.
What the rater guidelines ask about who is behind a page
The September 2025 edition of the Search Quality Rater Guidelines tells raters to start by "finding out who is responsible for the website and who created the content on the page".2 It separates experience from expertise. Experience is first-hand or life experience with the topic. Expertise is "the necessary knowledge or skill for the topic".2 For YMYL pages that give information or advice, the guidelines say "a high level of expertise may be required for the page to be trustworthy", while personal stories can carry weight when they are consistent with expert consensus.2
For a practice this cuts two ways. A patient story is experience. A clinical explanation needs a named clinician with stated training, and the bio page is where you show it.
What should a practitioner bio page include?
Write it so a skeptical patient, a referring doctor and an AI assistant can each check it without calling you. That means facts that exist somewhere else as well as on your site.
| Element | What to write | Where it can be verified |
|---|---|---|
| Full name and credentials | Name exactly as licensed, then letters (DC, DDS, ND, LAc, RDN) | State licensing board lookup |
| License | State and license number, and every state you are licensed in | State licensing board lookup |
| NPI | The 10-digit number, if you have one | NPPES NPI Registry |
| Training | School, degree, year; board certifications by name | School or certifying body |
| Scope | What you see patients for, and what you refer out | Your own service pages, consistently |
| Memberships | Associations you actually belong to | The association’s member directory |
| Photo | A current, real photo of you | Your Google Business Profile photos |
Use the name the license uses. If the board lists "Katherine" and your site says "Kate", an assistant comparing sources has one more reason to hedge. And keep the scope line: saying what you do not treat reads as more trustworthy, not less.
How does the NPI Registry fit in?
Since 2007, CMS has published the provider data in NPPES that is disclosable under the Freedom of Information Act. The NPI Registry is "a query-only database which is updated daily", free to search by NPI or by name.3 It shows what you, or someone acting for you, reported to NPPES.3 That usually includes practice addresses, phone numbers and your taxonomy.
Covered providers are required to report changes to their NPPES data within 30 days of the change.4 In practice many do not, and the registry keeps an address from two moves ago. When your bio says one thing and a federal database says another, the database often wins in a patient’s mind and sometimes in an AI answer. Open the registry, search your own name, and correct it before you polish the bio. The wider version of this job, matching every listing, is covered in becoming the practice AI recommends.
Bylines on articles
Every article on the site should show who wrote it and, where it applies, who reviewed it clinically, with both names linking to their bio pages. Google’s article markup guidance asks that every author shown on the page also appear in the markup, each in a separate author field, with a url or sameAs pointing to a profile page.6 It also says the author name field should hold only the name, with no job title or honorific.6
If an article was drafted by staff or with software and then checked by a licensed practitioner, say that. "Written by the practice team, reviewed by Dr. Ana Ruiz, DC" is a checkable claim.
Person markup: repeat the page, do not decorate it
Schema.org’s Person type has the properties a bio needs: jobTitle, worksFor, alumniOf, hasCredential ("a credential awarded to the Person"), knowsAbout and sameAs, which is a "URL of a reference Web page that unambiguously indicates the item’s identity".5 Good sameAs targets are your NPI Registry entry, your licensing board record if it has a stable URL, and your professional association profile.
The rule that matters is the one in the schema markup guide: markup may only state what the page visibly states. A hasCredential entry for a certification that appears nowhere on the page is a claim to machines that you are not making to people.
Common mistakes
- A single "Meet the team" page with first names only and no credentials.
- Credentials listed as a string of letters with no license state or number.
- Stock photos, or a headshot ten years old.
- Claims of "leading expert" or "top-rated" with nothing checkable behind them. A claim you cannot prove is a problem for the same reason covered in health claims on a practice website.
- A bio that differs from the Google Business Profile, the registry and the association directory on basic facts.
Checking bios, bylines, the registry and the markup together is part of a credibility audit. This post explains public guidance as published. It is not legal advice, and license and scope-of-practice questions belong with your state board or a lawyer.
