Doctolib, Google, PagesJaunes: Where Do AI Dental Recommendations Come From?

When ChatGPT recommends a dentist in the 15th arrondissement of Paris, where does it get that information? When Perplexity cites a practice for a dental implant, which source appears at the bottom of its response? And when Google AI Overview synthesizes the best dentists in a neighborhood, what data feeds its answer?

Understanding the sources means understanding the game. If you know exactly where AI recommendations come from, you know exactly where to focus your efforts. That is the difference between acting randomly and acting strategically.

This article maps the sources used by each AI platform for dentist recommendations in Paris, ranked by frequency and impact.

The Source Hierarchy: Overview

By cross-referencing data from our GEO audits, international studies (Yext on 2.2 million healthcare citations, SMX Paris 2026 on 15,000 geolocated queries), and the analysis of visible citations on Perplexity, here is the source hierarchy for Parisian dental queries, ranked by frequency of appearance.

Tier 1 — Primary sources (present in 50% or more of AI responses containing a dental recommendation): Google Business Profile and Google Reviews, Doctolib.

Tier 2 — Secondary sources (present in 15 to 40% of responses): Dental practice websites, PagesJaunes.

Tier 3 — Complementary sources (present in 5 to 15% of responses): Directory of the Order of Dental Surgeons, specialized health directories (Allo-Dentiste, Annuaire-Dentiste), editorial content and health blogs.

Tier 4 — Marginal sources (present in less than 5% of responses): Social media (Instagram, Facebook), forums and discussions (Reddit, Doctissimo), Wikipedia (for general dental care information, not for specific practices).

This hierarchy has a direct implication: if you are only optimized on Tier 3 and 4 sources, you are invisible. The bulk of your investment should go toward Tier 1, then Tier 2.

Source #1: Google Business Profile and Google Reviews

This is the most universal source. All three major AI platforms consult it.

For Google AI Overview, it is the absolute primary source. Google draws from its own ecosystem with 100% accuracy on factual data. Your GBP listing is literally the raw material for Google AI.

For Perplexity, Google Reviews is the second most cited source after Doctolib for dental queries in Paris. Perplexity extracts the average rating, number of reviews, and sometimes specific review excerpts to support its recommendation.

For ChatGPT, Google Reviews is a dominant source. Analysis of ChatGPT response content shows a strong correlation between the descriptions used by the AI and the text of Google reviews — confirming that ChatGPT reads and synthesizes reviews.

What you need to optimize: Complete your GBP listing to 100% (see our complete guide). Accumulate recent reviews containing service-related keywords (see our guide to Google reviews). Respond to every review. Publish posts regularly. This is the foundation of any GEO strategy for a dentist.

Estimated time investment: 1 to 2 hours per week for ongoing management, after an initial optimization of 3 to 4 hours.

Source #2: Doctolib

This is the specificity of the French market — and a strategic advantage that international GEO guides never mention. Doctolib is the dominant medical appointment booking platform in France, with tens of millions of users. For AI assistants, it is a reliable and structured medical data source.

For Perplexity, Doctolib is the most frequently cited source for dental recommendations in Paris. In our tests, Doctolib appears as a source in about 68% of Perplexity responses containing a dentist recommendation. This makes sense: Doctolib provides structured data (specialties, address, hours, availability, photos, patient reviews) that Perplexity can cite directly with a verifiable link.

For ChatGPT, Doctolib is an important source but less dominant than for Perplexity. ChatGPT uses Doctolib for factual information (specialties, address) but complements it with other sources for the “recommendation” dimension.

For Google AI Overview, Doctolib is not a direct source — Google prefers its own data. However, a well-referenced Doctolib profile can appear in standard Google search results, which indirectly influences Google AI.

What you need to optimize on Doctolib: Write a complete description of your practice (not just “Dental practice”). List all your specialties individually. Add professional photos of your practice. Ensure your address and phone number are identical to your Google Business listing. Encourage reviews on Doctolib in addition to Google reviews.

Estimated time investment: 1 hour for the initial optimization, then 15 minutes per month to verify that information is up to date.

Source #3: Your Website

A clean, up-to-date, and structured website is the third most impactful source for your AI visibility. But be careful: not just any website. AI assistants do not read your site the way a patient would. They look for exploitable data.

What makes a website useful for AI: Schema.org structured data (the most direct technical lever — see our Schema.org guide). Detailed service pages with clear answers to the questions patients ask. A structured FAQ page. Visible NAP information consistent with other platforms. Recently updated content (AI assistants favor pages with a recent last-modified date).

What makes a website useless for AI: A single-page showcase site with no textual content. A site whose information has not been updated in years. A site without any structured data. A site whose content is duplicated from a dental network template.

The case of practices without a website: In our study of 50 Parisian practices, 34% had no website. None of these practices appeared in the group visible to AI assistants. The absence of a website is a significant handicap because it reduces the number of sources AI can cross-reference for you. If a full website is not feasible, a minimal site with your basic information, services, and structured data is always better than nothing.

Estimated time investment: Variable depending on what already exists. Schema.org implementation takes 1 to 2 hours for a webmaster. Content enrichment (service pages, FAQ) can take 1 to 2 days of writing.

Source #4: PagesJaunes

PagesJaunes remains a relevant source for AI assistants, despite its declining popularity with the general public. Why? Because PagesJaunes is a structured, verifiable, and long-standing directory — three qualities that AI assistants value.

When PagesJaunes appears: Primarily on Perplexity, which cites PagesJaunes in about 18% of dental responses. ChatGPT consults it less frequently but references it to verify factual information (address, phone number).

What you need to do: Verify that your PagesJaunes listing exists and that the information is strictly identical to your Google Business listing. If you do not have a listing, create one — it is free and takes 10 minutes. PagesJaunes is not your number one priority, but it is a consistency signal that reinforces AI trust.

Estimated time investment: 10 minutes for creation or verification, then an annual check.

Source #5: Directory of the Order of Dental Surgeons

The Order’s directory is a unique authoritative source for the dental sector. It confirms that you are a registered, qualified, and authorized practitioner. It is a credibility signal that AI assistants cannot find anywhere else.

How AI uses it: AI assistants do not directly cite the Order’s directory in their responses, but they use it in the background to verify a practice’s legitimacy. A practice listed in the Order’s directory with consistent information benefits from an implicit trust signal.

What you need to do: Verify that your information on the Order’s directory is up to date and matches your other profiles. This is often overlooked because the directory is managed by the Order itself, but the information can be outdated if you have changed address or phone number.

Source #6: Specialized Health Directories

Directories such as Allo-Dentiste, Annuaire-Dentiste.fr, or Kelest contribute to what GEO specialists call “mention coverage.” The more you are listed in directories with consistent information, the more AI assistants perceive your practice as an established and reliable player.

These sources are rarely cited directly in AI responses, but they function as validation signals. An AI that finds your practice mentioned consistently across 7 platforms considers it more reliable than one that appears on only 2.

What you need to do: Register on 3 to 5 relevant health directories with the same information as everywhere else. The time investment is minimal (30 minutes total), and the cumulative signal is real.

The Priority Action Plan

Here is how to allocate your time based on each source’s impact on your AI visibility.

Priority 1 — Google Business Profile (40% of your effort). This is the source that feeds all three AI platforms simultaneously. Initial optimization takes 3-4 hours, then 1-2 hours per week for ongoing management (reviews, posts, photos). It is the investment with the best return.

Priority 2 — Doctolib (25% of your effort). Essential for Perplexity and influential for ChatGPT. Initial optimization takes 1 hour. After that, it is light maintenance: keep your profile up to date and encourage reviews.

Priority 3 — Website + Schema.org (20% of your effort). Impactful for all three platforms, especially Google AI Overview. If you already have a site, adding Schema and enriching content is a one-time investment. If you do not have a site, it is a larger project but one that multiplies your chances of AI visibility.

Priority 4 — Secondary directories (10% of your effort). PagesJaunes, Order of Dental Surgeons, health directories. One-time registrations or verifications, then forget about them — their role is to exist with consistent information, not to be actively managed.

Priority 5 — Editorial content and third-party mentions (5% of your effort). Being mentioned in a health blog post, a neighborhood guide, or editorial content is a bonus that strengthens your ChatGPT visibility. It is not an immediate priority, but if the opportunity arises, take it.

The Strategic Lesson: Being Consistently Present Everywhere Beats Being Perfect Somewhere

The most determining factor is not the perfect optimization of a single platform. It is the consistency of your information across all sources.

A practice with an average Google listing, a basic Doctolib profile, and a decent PagesJaunes listing — but with strictly identical information everywhere — will be better perceived by AI assistants than a practice with a perfect Google listing but inconsistencies on other platforms.

AI assistants triangulate. They cross-reference data from multiple sources to establish a trust level. Each consistent source strengthens trust. Each inconsistency erodes it.

This is the fundamental principle of GEO: building a digital presence that AI assistants can leverage with confidence, wherever they look.

FAQ — AI Recommendation Sources for Dentists

Do Doctolib reviews count as much as Google reviews?

Google reviews have a broader impact because they are consulted by all three AI platforms (ChatGPT, Perplexity, Google AI). Doctolib reviews are primarily used by Perplexity. Our recommendation: focus 70% of your review collection effort on Google and 30% on Doctolib.

Do I need to be on every possible directory?

No. Quality trumps quantity. Being consistently present on 5 to 7 key platforms (Google, Doctolib, your website, PagesJaunes, Order of Dental Surgeons, 1-2 health directories) is more than sufficient. Multiplying registrations on obscure directories without keeping them updated can create inconsistencies — which is counterproductive.

Do social media (Instagram, Facebook) influence AI recommendations?

Marginally. Google now indexes Instagram profiles of businesses, which can indirectly influence Google AI Overview. But for dentists, social media is not a significant source of AI recommendations. Your time is better invested in Google Business, Doctolib, and your website.

If I change my phone number or address, which platforms should I update?

All of them, and ideally at the same time. Start with Google Business (primary source), then Doctolib, your website, PagesJaunes, the Order’s directory, and any other directory where you are listed. An old phone number lingering on a single platform can create an inconsistency that AI assistants detect.
