The trust signals that matter most on a veterinary or pet care website are a verifiable license, real accreditation and vet-reviewed health content. For pet sitters, add proof of insurance and bonding. Pet owners trust you with an animal they love. This guide is part of our Trust Signals and E-E-A-T Guide.
Google says E-E-A-T (experience, expertise, authoritativeness and trust) isn't a specific ranking factor. It still asks whether readers can tell who created content, and whether that person has relevant expertise. Pet health advice is a place where that question matters, because readers may act on it.
Each business type uses different signals. A hospital leans on licenses and accreditation. A sitter or groomer leans on insurance, certification and references. Use only what you really hold.
Key Takeaways
- Link each veterinarian to their state board's license lookup.
- California law limits "veterinary specialist" and "board certified" to people certified by recognized organizations.
- AAHA accreditation is earned against published standards, so name it only if your hospital holds it.
- Fear Free has separate certifications for individuals and practices, so use the correct one.
- For pet sitters, name your insurance and bonding, and say what they cover in general terms.
- Never add a "Reviewed by" line unless the named person actually reviewed that page.
The credentials that matter in veterinary and pet care
| Credential | Who holds it | How owners verify it |
|---|---|---|
| Veterinarian license (DVM or equivalent) | Individual veterinarians | State board, such as the California Veterinary Medical Board "Verify a License" tool |
| Registered veterinary technician | Licensed or registered technicians, by state | State board lookup |
| AAHA accreditation | Veterinary hospitals | AAHA "Find an AAHA-Accredited Hospital" |
| Fear Free Certified Professional | Individuals, including vets, groomers, trainers and sitters | Fear Free directory |
| Fear Free Certified Practice | Veterinary practices | Fear Free directory |
| CPPS (Certified Professional Pet Sitter) | Pet sitters | Pet Sitters International |
| Insurance and bonding | Pet businesses | Certificate from your insurer, available on request |
AAHA
The American Animal Hospital Association says its Standards of Accreditation contain more than 900 standards, with only about 50 mandatory and the rest scored on points. AAHA also says around 15% of practices achieve accreditation. You can repeat those figures with a link, as of November 2026. Do not change them into "top 15%," which suggests a quality ranking AAHA did not state.
Fear Free
The Fear Free site separates two things. Certified Professionals are individuals who finished an online certification program. Veterinary Practice Certification applies at the facility level and requires the whole team, a list of standards and a virtual visit. So one certified technician does not make your clinic a Fear Free Certified Practice.
Pet sitters
Pet Sitters International lists a certification program and an insurance resource page. The insurance page says coverage is not included with PSI membership. So "PSI member" is not the same as "insured."
We did not verify a general US licensing rule for pet sitters, and local rules may apply. Check your city, county and state before you describe yourself as "licensed."
What the rules say about showing them
We did not find a general rule requiring every veterinary website to display a license number. Some state rules do limit the claims you can make.
California is a clear example. Business and Professions Code section 4883 lets the Veterinary Medical Board discipline licensees for several things:
- False or misleading advertising (subdivision f).
- Specialist claims (subdivision s). This covers saying a licensee or registrant is a "veterinary specialist" or "board certified." They must be certified by a specialty organization recognized by the American Veterinary Medical Association or the National Association of Veterinary Technicians in America.
So a California general practitioner should not write "dental specialist" or "board-certified in surgery" on the basis of a course or a special interest. "Special interest in dentistry" is safer, if it is true. Your board may use different wording, so confirm before publishing.
Rules vary by state; confirm with your licensing board or counsel.
Reviews and health claims
The FTC rule on consumer reviews and testimonials, effective 21 October 2024, applies to pet businesses too. It covers fake reviews, buying reviews tied to a sentiment, insider reviews and review suppression. Do not delete honest bad reviews from your site and describe what remains as all your reviews. Our reviews and testimonials guide explains the details.
If you sell pet supplements or foods, health claims need evidence. The FTC's Health Products Compliance Guidance describes the standard for health-related products as competent and reliable scientific evidence. It is written around human health products, so ask counsel how it and FDA rules apply to animal products.
Bylines and reviewers for pet health content
Articles on toxins, vaccines, dosing, surgery recovery or symptoms need a qualified check. In our 149-site audit, 105 of 130 sites with articles had sampled articles credited to the company or to no one.
Who should write. A veterinarian, a credentialed technician or a writer working from their notes. A groomer or trainer can write from experience on their own craft.
Who should review. A licensed veterinarian should review medical content. A credentialed technician can review nursing care and handling, within their role. Non-medical content may not need a vet, such as how to prepare a pet for a sitter visit.
What the line should say.
"Reviewed by [Dr. full name, DVM], [state] license [number]. Last reviewed [date]."
Never add a "Reviewed by" line unless the named person actually reviewed that page. A pet store or sitter who has no vet on staff should not borrow a vet's name. Hire one to really review the page, as our reviewer hiring guide explains. Otherwise, leave the line off and send readers to their own vet.
How often. Recheck urgent care, toxin and medication pages at least yearly. Recheck sooner if a label or guidance changes. Do not change the visible date without a real recheck, as our last updated dates guide explains.
No dosing advice. Avoid general dose amounts for medications. Tell owners to call their veterinarian or an emergency clinic about urgent symptoms.
Where each signal goes on your site

Schema.org has a VeterinaryCare type for a vet's office. Schema describes visible facts, and it does not guarantee a rich result. Keep credentials in real text, not in images only. Our schema markup guide has examples, and our team and provider page guide covers staff bios and consent.
Common mistakes
- Calling a general practitioner a "specialist" because of a course or interest.
- Showing the AAHA logo after accreditation has lapsed, or on a location it does not cover.
- Treating one staff member's Fear Free certificate as certification of the clinic.
- Saying "licensed, bonded and insured" without knowing whether a license exists for your service.
- Publishing pet health advice credited to "the team," with no vet check.
- Using stock photos of pets and staff as if they were your own.
Next step
Check each doctor profile for license links and specialist wording, then confirm your accreditation and certifications are current. Add vet review where it really takes place. See our veterinary and pet website services, or get a free 20–30 page website audit within 24 hours.
Frequently asked questions
Do veterinarians have to show a license number online?
We did not find a universal rule. State boards set their own requirements, so check yours. Showing the number with a lookup link is an easy way to let owners verify it.
Can a general practice vet call themselves a specialist?
In California, the statute limits "veterinary specialist" and "board certified" to people certified by recognized specialty organizations. Other states may differ. Describe a special interest honestly instead, and confirm the wording with your board.
Is AAHA accreditation required?
No rule we found requires it, and it is earned through AAHA's own process. AAHA says about 50 of its more than 900 standards are mandatory, with the rest scored. Only mention it if your hospital currently holds it.
What should a pet sitter say about insurance?
Name the coverage you hold in general terms, and offer a certificate on request. PSI says insurance is not included in its membership, so do not treat membership as coverage. Make sure the policy is current before you say so.
Who should review pet health articles?
A licensed veterinarian should check medical topics. Only name them if they really read and approved the article, and keep a dated record. For urgent symptoms, tell owners to contact a veterinarian.
