Landing page for a dietitian: display the right credential, avoid the wrong visual

"Dietitian" (diététicien) has been a title protected under France's Public Health Code since a 2007 law: only someone holding a diététique-specific vocational degree (BTS diététique, DUT génie biologique with a diététique specialty, or an equivalent state diploma) can legally use it, and misusing the title is a criminal offense. "Nutritionist," by contrast, is protected by no legal text at all — after a few weeks of online certification, anyone can legally call themselves a "nutritionist" on social media. For a genuinely qualified dietitian-nutritionist, the landing page therefore has a first job to do before it even tries to convince a visitor to book — proving in a few seconds that this isn't just another improvised Instagram account.

Clearing up the confusion before selling anything

A visitor typing "dietitian" or "nutritionist" into a search engine generally can't tell the two apart — and that exact ambiguity is what lets unqualified "nutrition coaches" compete on the same search terms, often with promises that a trained professional's code of conduct forbids. The page can't rely on a title alone: it needs to show, on the very first screen, what sets a state-recognized diploma apart from a weekend certification.

• The exact credential (BTS diététique, DUT génie biologique, state diploma) rather than a vague "nutrition specialist."
• The registration number (ADELI in France), required to practice and independently verifiable, which immediately signals a professional registered with the regional health authority.
• Membership in a professional association (in France, AFDN — Association française des diététiciens nutritionnistes) where it applies, a marker the public is increasingly learning to recognize.
• Real areas of expertise (diabetes, eating disorders, sports nutrition, prenatal and postnatal nutrition, allergies) rather than a generic promise of "weight loss."

The structure that builds trust in one page

1. Hero with the exact title and specialty: "State-registered dietitian-nutritionist in [city] — sports nutrition and eating disorders." The word "registered" in the first line does the sorting immediately.
2. A credibility block right below the hero: diploma, registration number, years in practice, continuing education — visible without scrolling, exactly where a skeptical visitor looks for proof before reading anything else.
3. A clear consultation format: in-office, home visit, or video consultation, with the duration and price of each type of appointment rather than a vague "quote on request" that pushes the visitor to compare elsewhere.
4. A care pathway rather than a promised outcome: describing the steps (initial assessment, personalized plan, follow-up sessions) conveys professionalism without ever promising a number on the scale.
5. Real online booking, along the lines detailed in our article Calendly vs. a contact form: a calendar with visible slots reassures far more than a bare "leave your number" field.
6. Written testimonials focused on the care experience (listening, guidance, adapting the plan) rather than on a number of kilos lost, which raises both a professional-conduct problem and an unverifiable-claim problem.

The before/after visual trap

Before/after visuals are among the most effective social-proof formats on a landing page — we cover the right way to use them in our article on before/after photos: how to make them convincing (and legal). But on a dietitian-nutritionist's page, this format deserves particular caution, for two compounding reasons: it shifts the message toward a numerical outcome that the profession's code of conduct forbids promising, and it can backfire. A study by Geier, Schwartz, and Brownell, published in 2003 in Eating and Weight Disorders ("Before and after" diet advertisements escalate weight stigma), exposed participants to diet ads with or without a before/after photo pair: the group shown the before/after pair rated weight as significantly more "easily controllable" than the other groups, a judgment linked to stronger stigma toward people who are overweight. For a health professional whose role is precisely to help patients build a calmer relationship with food, this format can end up contradicting the very message the consultation is meant to deliver.

An alternative that converts just as well: written testimonials focused on the process ("she took the time to understand my work schedule before proposing a plan"), years of practice, and non-visual indicators when the patient explicitly authorizes them (biological markers tracked as part of a specific medical condition, with their consent).

Why a "video consultation" button matters more than it looks

Offering a remote slot isn't just a marketing convenience: a secondary analysis of the Australian Healthy Rural Hearts randomized trial, published in 2025 in the International Journal of Behavioral Nutrition and Physical Activity (The effect of telehealth-based medical nutrition therapy on cardiovascular disease risk factors in a rural population), followed patients receiving five remote dietary consultations over six months: the telehealth group significantly increased the share of their diet coming from nutrient-dense foods compared with the usual-care group, along with better perceived quality of life. For a practice hesitant to feature video consultations on its page for fear it looks "less serious" than in-person care, this result is a direct counterargument: done well, it isn't a fallback option but a care format in its own right — and a "book a video call" button deserves the same prominence as "book in-office."

The rules to follow

• No promised numerical outcome ("lose X kg in Y weeks"): this kind of claim, common among unqualified coaches, exposes a regulated professional to disciplinary and professional-body sanctions — see our guide on landing pages in a regulated industry.
• No unauthorized health claim on any supplement or product that might be recommended: regulation strictly governs what can be stated as fact.
• Explicit consent for health data collected through the form (history, goals, conditions): this is sensitive data under GDPR, requiring a clear legal basis and clear disclosure, beyond the generic consent used for a simple contact request.
• A clear distinction from medical advice: stating that the consultation doesn't replace medical care for an already-diagnosed condition removes any ambiguity about the professional's role.

The costliest mistakes

• Not displaying the credential: in a market where anyone can call themselves a "nutritionist," the absence of proof of training reads as an absence of qualification, even when that's not the case.
• Numerical before/after photos: beyond the professional-conduct risk, the Geier study shows they reinforce stigma rather than trust in the care being offered.
• Only one consultation format: ignoring video consultations shuts out patients (in rural areas, with tight schedules) from a care format whose effectiveness is now documented.
• A health form with no specific GDPR notice: collecting medical history without an explicit legal basis is a real compliance gap, not just a theoretical one.
• A slow or unreadable mobile page: as with any health-related booking, the search often happens under time pressure — see our article on page speed and conversion.

Building the page in a day

Whether you're opening a new practice or clarifying your positioning against unqualified coaches in an established one, the technical base stays the same: a hero with the credential in view, an online calendar for both in-office and video slots, and testimonials focused on the care experience rather than numbers. LanderKit's practitioner / consultant template provides this structure — hero, credibility, specialties, booking, reviews — for €89, no subscription, on free hosting. Our articles on the therapist landing page and on landing pages in a regulated industry round out this guide if your practice combines several types of care.
