Profitability simulator

What strong search visibility can bring your practice

This simulator was built by cross-checking a large number of serious studies in the field (French national health insurance, UNASA, Fiducial, Doctolib and UFSBD, studies on Google clicks, practice panels) with what you tell us about your practice. It gives an idea of the potential results, without being able to guarantee them: results vary from one practice to another. No revenue to enter, and nothing is sent anywhere: everything is calculated in your browser. The sources are at the bottom of the page.

Your practice

A few reference points are enough. The default values are those of a typical practice.

Country
How this works

The country sets three things: the price level of treatments (Belgium and Luxembourg at the French level, Switzerland 2.5 times more expensive: implant ≈ CHF 3,500, crown CHF 1,700 to 2,200 versus €600 in France), what a loyal patient spends each year (France €360 according to the French national health insurance, Belgium €300, Switzerland €800, Luxembourg €450) and the price of an implant, used only for the “so many implants per month” equivalent. The number of new patients per inhabitant is the same everywhere: 7.6 per month per 1,000 inhabitants.

Your city
How this works

The size of the city gives the number of people searching for a dentist on Google around you each month. Calculation: France has 54 private-practice dentists per 100,000 inhabitants (French national health insurance, 2024) and a dentist sees 14 new patients per month (Doctolib and UFSBD), i.e. 7.6 new patients per month per 1,000 inhabitants; 17 to 33% of them go through Google or Google Maps (25% at the middle of the gauge). We use 15,000, 45,000 or 80,000 inhabitants. Example, mid-sized city: 45,000 × 7.6 ÷ 1,000 × 25% = 86 “Google” patients per month, shared among the practices in the area.

Practitioners at the practice
How this works

The practice owner performs 1 in N of the additional treatments, the associate dentists the rest. On associates' patients, we deduct the associate's share of fees (about 50%) on top of the lab and supplies; on the owner's patients, only the lab and supplies. The percentage shown below is the average of the two, weighted by what a new patient spends on the services selected.

How many additional new patients per month can you take on?
How this works

For reference: a dentist already sees 14 new patients per month on average (Doctolib and UFSBD). One free slot a day means about ten new patients a month.

This is a ceiling: if SEO brings more patients than you can take, the simulator stops at your number, and you choose the most interesting cases. “No limit” removes the ceiling; “practice full” sets the result to zero.

10 per month
Practice fullNo limit
What you offer
How this works

What a new patient spends in the first year, in France: €350 of routine care (check-up, X-rays, cleaning, a few fillings, sometimes a root canal; 2 to 3 times what an established patient spends on routine care), then, assuming half of treatment plans are not accepted: + €270 for crowns and prosthetics (3 patients in 10 accept a plan of about €900), + €200 for implants (1 in 10, ≈ €2,000), + €175 for orthodontics (1 in 20, ≈ €3,500), + €150 for cosmetic dentistry (1 in 20, ≈ €3,000). A typical practice reaches ≈ €820, i.e. 2 to 3 times a patient's average annual spend (€360), which is what practice panels measure.

Each service selected also brings patients who search Google for that specific treatment (“dental implant + city”, “aligners + city”): 0.8% of the area's “Google” patients per service. With routine care unselected, you no longer take new patients for it: only those searching for a specific treatment count (1% of the area per service), and they spend the price of the treatment: crowns €1,400, implant €2,000, orthodontics €3,500, cosmetic dentistry €3,000.

The money comes in at the pace of treatment: 6 months for routine care, 4 for a crown, 6 for an implant (healing included), 18 for orthodontics paid per semester or in monthly installments, 2 for cosmetic dentistry.

Your Google ranking for “dentist + your city”
How this works

Your ranking for “dentist + your city” sets the share of the area's “Google” patients you capture today: 1st 20%, 2nd or 3rd 15%, 4th or 5th 5%, 6th to 10th 3%, 11th to 20th 1%, lower than that 0.5%. These shares come from the click-through rates measured in Google's local pack (17.6% in 1st position, 15.4% in 2nd, 15.1% in 3rd, then a sharp drop; First Page Sage 2026, Monday Digital).

The ranking gain = what the top 2 would capture (13 to 20% depending on the gauge) minus what you already capture, multiplied by the area's “Google” patients. To this we add treatment-specific searches, the conversion of people who already find you but did not call (15% of your current flow), and AI (0.25 to 0.75 patients per month). Already 2nd or 3rd: a one-in-two chance of moving up to 1st. Already 1st: what remains is treatment-specific searches, conversion and AI. The total is capped at 12 to 20 patients per month, then at your capacity.

Your visibility score (out of 100)
How this works

The score sets the ramp-up: the share of the full run rate of new patients reached month by month from signing. Under 30: 15%, 40%, 60%, 75%, 85%, 92%, 97%, full run rate by the 8th month (simple fixes to the Google Business Profile and the website have a strong effect). From 30 to 69: 10%, 30%, 50%, 65%, 75%, 85%, 92%, full run rate by the 8th. 70 and above: 0%, 15%, 30%, 45%, 60%, 70%, 80%, 90%, full run rate by the 9th (only the slow levers remain: treatment pages, reviews, AI). These curves come from the measurements cited at the bottom of the page: the map reacts to the profile within 1 to 3 days and to the linked page within 2 weeks, new pages break through in 2 to 6 months, and reviews build up at the pace of patients.

Estimate
How this works

The gauge moves the uncertain assumptions together: the share of new patients who come through Google (17 to 33%), the share captured in the top 2 (13 to 20%), a new patient's spend (−20% to +20%), the ceiling on patients per month (12 to 20) and patients coming from AI (0.25 to 0.75 per month). In the middle: the most likely values according to the studies. Margin, retention and the pace of treatment do not move with the gauge.

Where the numbers come from, and how we calculate

We read the official statistics and the studies available in September 2026, country by country. Each figure carries a label: Measured for a public statistic or an accounting panel, Estimated for a calculation or an extrapolation from measured data.

  1. 1. How many patients search for a dentist on Google near youFrance has 54 private-practice dentists per 100,000 inhabitants, and a dentist sees 14 new patients per month on average. Of these new patients, 17 to 33% have Google or Google Maps as their first point of contact, 25% at the middle of the gauge (the rest come from word of mouth, booking platforms and referrals from other dentists). The size of the city gives the number of “Google” patients to be shared each month.
  2. 2. What share you capture, depending on your rankingOn a local search, the first result on the map gets 18 to 24% of clicks, the second and third about 15% each, and beyond the third the drop is sharp. We compare what you capture today with what the top 2 would capture, and we add treatment-specific searches (implant, aligners, emergency), the conversion of people who already find you, and AI. The total is capped, then limited to what you can take on.
  3. 3. What a new patient brings in, once everything is paidA patient spends €360 a year on average at their dentist. A new patient spends 2 to 3 times more in the first year: check-up, X-rays, cleaning and a few fillings (≈ €350), then, depending on what you offer, a prosthetic plan for 3 in 10, an implant for 1 in 10, orthodontics or cosmetic work for 1 in 20, assuming half of treatment plans are not accepted: about €820 for a typical practice. On one additional patient, we only deduct what the treatment really costs: the lab and supplies (8% on routine care, about 30% on a crown, an implant, aligners or veneers; 19% of revenue on average according to Fiducial), a little assistant time (5%), and the associate dentist's share of fees if an associate performs the treatment (about 50%). Rent, equipment, social contributions and tax are not deducted: they are there whether the patient comes or not. This leaves about 75% to the practitioner who treats the patient personally, and 25 to 30% to the practice on an associate's patients.
  4. 4. When the money really comes inGoogle reacts quickly to a corrected Google Business Profile (one to three days) and to a rebuilt website (two weeks), but reviews build up at the pace of patients, new pages break through in two to six months and directories take months: the full run rate is reached around the eighth month, provided patients are systematically asked for reviews (QR code at the practice, reminders), which is part of our service. A practice starting from far behind gets off to a stronger start (simple fixes have a strong effect); a practice already in good shape only has the slow levers left, and starts a month later. In between, the patient who finds you books an appointment ten days later, at the median. And each patient pays at the pace of their treatment: six months for routine care, four for a crown, six for an implant (healing included), eighteen for orthodontics paid per semester or in monthly installments, two for cosmetic work. After that, 7 new patients in 10 come back the following year, then 15% leave each year, and those who stay spend the average. The whole thing is simulated month by month over five years.

What this simulator is, and is not. It was built by cross-checking a large number of serious studies in the field, listed above, with what you tell us about your practice. It gives an idea of the potential results, but cannot guarantee them: results vary from one practice to another, and no one can promise a position on Google; in fact, the law prohibits dentists from buying one. It is an order of magnitude, built on national averages and on what you tell us. It does not replace the diagnostic of your practice, which we carry out free of charge based on your Google Business Profile, your website and the practices around you. The assumptions are shown in the calculation details, and the “pessimistic to optimistic” gauge lets you make them tougher. Returns over 2, 3 or 5 years assume you keep your ranking; the retention used (7 new patients in 10 come back the following year, then 15% leave each year) comes from US panels, in the absence of a French measurement. The gross margin shown is what remains once the lab, the supplies and whoever performs the treatment are paid, before rent, equipment, social contributions and income tax; our invoice, for its part, is tax-deductible. Prices exclude tax.
