How does ChatGPT decide which dentist to recommend?
ChatGPT's web search retrieves through Bing's index. We check Bing indexing, business-information consistency, review data and treatment content alongside whether ChatGPT names a practice; we have not measured whether changing any one of those checks causes a practice to be named.
Unlike a Google search, ChatGPT doesn't return a page of links you scroll through. It synthesizes an answer and names a few businesses directly. That makes the stakes higher: being fourth is the same as being invisible. Understanding the pipeline — retrieval, then selection — is what lets you influence it.
Being eligible and being chosen are different things. SOCi's 2026 Local Visibility Index analyzed nearly 350,000 locations across 2,751 multi-location brands and found ChatGPT recommended about 1.2% of those locations.

Does ChatGPT use Google, or does it use Bing?
ChatGPT search leans on Bing's index plus business-data providers and review consistency, not Google's index alone. For a local question it gathers 20 to 30 of the top web results and writes its answer from those, according to Search Engine Land's 2025 breakdown of ChatGPT local search. Bing indexing is what makes a practice eligible to be named. It is not a promise of being named.
The practical consequence is that your Google rankings tell you almost nothing about your ChatGPT visibility. If your site has never been submitted to Bing, ChatGPT has no reliable way to retrieve it, no matter how strong your Google SEO is. Being in the index is the floor, not the ceiling. In our June 2026 Columbus scan, the 21 practices whose Bing data we could read were all indexed, from about 50 pages to more than 145,000, and ChatGPT named none of the 58 practices we checked.

What does OpenAI's own documentation say about how ChatGPT search shows local businesses?
OpenAI's Help Center says ChatGPT search can use location to find local results and may share location with third-party providers for nearby business listings. It names two conditions for a website to be eligible: allow OAI-Searchbot to crawl it, and make sure the host or content delivery network allows OpenAI's published searchbot IP addresses. It also says ranking uses multiple factors and "Placement is not guaranteed." The article does not list those factors for local businesses.
The article says ChatGPT search "sometimes partners with other search providers" and, when it does, sends them rewritten queries. It does not name those providers in its text; the privacy policies it links for them are Microsoft's and Shopify's. The Bing-index point earlier on this page comes from Search Engine Land's reporting, not from this OpenAI article.
For local results, OpenAI says ChatGPT "may use an approximate location based on your IP address," and that device location sharing is optional and off by default. When results show the wrong area, its advice is to "Include your city, neighborhood, or postal code in your question." A local answer therefore depends partly on where, and how specifically, the question is asked, so when you check what ChatGPT says about your practice, include your city or postal code.
On eligibility, the second condition is the easy one to miss. OpenAI says to "confirm that the website host or content delivery network allows traffic from OpenAI's published searchbot IP addresses." A robots.txt file that welcomes the crawler does not help if a firewall or CDN setting turns it away, and this guide shows how to check whether your site blocks ChatGPT.
Two more OpenAI statements bear on what a practice can influence. In its ads FAQ, OpenAI says "Ads do not influence ChatGPT's answers" and that "advertisers have no ability to shape, rank, or alter ChatGPT's responses." Its separate shopping article covers product and merchant results and does not mention local businesses, so its ranking factors, such as price and availability, should not be read as applying to a dental practice.

Which local ranking factors does Google document for Business Profiles?
Google's Business Profile Help describes three factors for local results: relevance, distance and prominence. It also says there is no way to request or pay for a better local ranking. That describes Google Maps and Search. Neither Google's page nor OpenAI's article says ChatGPT applies the same factors.
| Factor | Google's wording |
|---|---|
| Relevance | "Relevance is how well a Business Profile matches what someone is searching for." Google advises providing complete and detailed business info. |
| Distance | "Distance refers to how far each business is from the customer who's searching." If a customer does not share where they are, Google uses what it knows about their location. |
| Prominence | "Prominence means how well-known a business is." It is also based on info such as how many websites link to your business and how many reviews you have; Google says more reviews and positive ratings can help local ranking. |

What are the steps that get a clinic into ChatGPT?
In order: allow AI crawlers in robots.txt, get indexed in Bing via Bing Webmaster Tools and IndexNow, add LocalBusiness and Dentist schema, keep your review rating near the roughly 4.3-star average AI-recommended practices tend to carry, keep reviews fresh, and make your name, address and phone identical across every platform. In our own scans most practices already sit near or above that average. The structured-data step is where they fall down. The first step is worth checking rather than assuming: across 6,497 US dental practice websites, 7.6% block a crawler run by OpenAI, Anthropic or Perplexity, as set out in are dental websites blocking AI crawlers?
This existing checklist sits inside Citevio's Citation-to-Chair Protocol. The label on each item shows its closest protocol layer; it does not add or remove a step.
- Read — Open robots.txt to AI. Confirm OAI-SearchBot, GPTBot and ClaudeBot are not blocked.
- Discover — Get into Bing. Set up Bing Webmaster Tools, submit your sitemap, enable IndexNow, and submit key pages manually.
- Match — Add structured data. Implement LocalBusiness, Dentist and FAQ schema so AI understands your practice.
- Trust — Keep reviews healthy. Build genuine reviews toward the ≈4.3★ average AI-recommended practices tend to carry — a reference point, not a cutoff.
- Trust — Keep reviews fresh. A steady, recent flow signals an active, trusted practice.
- Match + Trust — Make your details consistent. Identical name, address and phone everywhere — inconsistency lowers AI trust.
The Answer layer uses measured question gaps to decide what the practice should explain next. The Chair layer connects that work to the practice's enquiry and booking path. They remain protocol layers, not extra items inserted into this technical checklist.
Step three is where most practices actually fail. We scanned 212 dental practices across two cities in June 2026 and checked each of these signals. Almost all of them had already done step one and had healthy reviews from step four. Almost none had step three.
| What we checked, June 2026 | Charlotte (154 practices) | Columbus, OH (58 practices) |
|---|---|---|
| Named by ChatGPT | 2 of 154 (1.3%) | 0 of 58 |
| robots.txt open to AI crawlers | 147 of 154 (95.5%) | 54 of 58 (93.1%) |
| Complete structured data | 3 of 154 (1.9%) | 3 of 58 (5.2%) |
| Average rating of the practices ChatGPT skipped | 4.82★ | 4.74★ |
| Median review count of those practices | 264 | 205 |

What limit does the open dataset show for these steps?
The open release covers 527 scanned dental practice websites across 7 US metros and domain-level records across 6,497 domains. It shows the observable website and access inputs behind the method. It does not measure a client result or show that changing any one input caused ChatGPT to name a practice.
The files are released under CC BY 4.0 with a DOI, and the raw data is downloadable. The release does not measure patients, booked appointments or revenue after these steps. It is evidence that the checks can be inspected and repeated, not evidence that a clinic will receive a recommendation.
For readers checking the archive rather than the summary, the identifier is explicit. The permanent DOI is 10.5281/zenodo.23143214.
How long until ChatGPT shows my practice?
Once your pages are indexed in Bing, they can begin appearing in ChatGPT within days to a few weeks. The technical foundation is quick; building the review and consistency signals that make ChatGPT confident enough to recommend you compounds over a 30 to 90 day window. No one can guarantee a specific position.
New domains and practices with thin review profiles sit toward the slower end of that range. The fastest wins usually come from clinics that already have good reviews and simply weren't indexed or structured correctly — for them, the fix can surface quickly.
Expect movement, not a fixed date. According to a 2025 Profound analysis of about 80,000 prompts per engine, roughly 40 to 60% of the domains an engine cites for a given question change within a single month. Visibility is something you re-check, not something you win once.

Frequently asked questions
Does ChatGPT use Google to find dentists?
No. ChatGPT search leans on Bing's index plus business-data providers and review consistency, not Google's index alone, so a practice absent from those sources can be invisible to ChatGPT even while it ranks well on Google. Search Engine Land's 2025 breakdown of ChatGPT local search describes it gathering 20 to 30 of the top web results and answering from those. Bing indexing is the entry condition, not a ranking promise, which is why a practice can sit on page one of Google and still never appear in ChatGPT.
How do I get my dental website into Bing so ChatGPT can find it?
Create a free Bing Webmaster Tools account, submit your XML sitemap, enable IndexNow for fast crawling, and manually submit your key pages. Make sure your robots.txt allows OAI-SearchBot and GPTBot. New pages typically appear in Bing within days to a few weeks, after which they can begin surfacing in ChatGPT.
What rating do I need for ChatGPT to recommend my practice?
In SOCi's 2026 local visibility index, the locations these engines actually recommended averaged 4.3 stars on ChatGPT, 4.1 on Perplexity and 3.9 on Gemini. Those are averages of what got recommended, not cutoffs you have to clear. Those averages do not show that changing a rating causes an AI recommendation, and Citevio has not measured that causal effect.
What is Bing Webmaster Tools and why does ChatGPT visibility depend on it?
Bing Webmaster Tools is the free account where you submit your sitemap, enable IndexNow and manually submit key pages so Bing actually crawls and indexes your site. Since ChatGPT's local search retrieves through Bing's index, a site that has never been submitted there gives ChatGPT nothing to find — no matter how well the same site ranks on Google.
What does enabling IndexNow actually do?
IndexNow is the setting that speeds up how fast Bing crawls new or updated pages, rather than waiting for its normal crawl schedule. It's listed alongside submitting your sitemap because getting a page into Bing's index quickly is what lets it start appearing in ChatGPT's local search sooner.
Which schema types should a dental practice add for ChatGPT?
LocalBusiness, Dentist and FAQ schema. Structured data restates, in a form a machine reads without guessing, what your practice is, where it is and what it treats — which is the step our June 2026 scan found practices skipping most often.
Why does robots.txt matter specifically for the crawlers ChatGPT uses?
Because it's where you confirm the specific crawlers ChatGPT and other assistants use aren't blocked — OAI-SearchBot, GPTBot and ClaudeBot by name. It's worth checking rather than assuming: across 6,497 US dental practice websites we studied, 7.6% block a crawler run by OpenAI, Anthropic or Perplexity, as set out in our study of dental websites blocking AI crawlers.
How many of the dental practices you scanned had complete structured data?
Very few. In our June 2026 scan, only 3 of 154 Charlotte practices and 3 of 58 Columbus practices had complete structured data. That gap was much larger than the gap in reviews or robots.txt access.
If most practices you scanned already had open robots.txt and healthy reviews, what was actually missing?
Structured data. Almost every practice in our scan already had an open robots.txt and healthy reviews — the first and fourth steps in the list above. Almost none had implemented step three, which is the one most practices in our scan actually needed to fix.
How consistent do my business details need to be across platforms?
Identical — the same practice name, address and phone number on your website, your Google Business Profile, and every directory or platform where you're listed. Our steps list this as the last of six checks: inconsistent details lower AI trust in what it's reading about you.
My practice ranks well on Google. Why might ChatGPT still not know I exist?
Because ChatGPT's local search doesn't consult Google's index. Your Google rankings tell you almost nothing about your ChatGPT visibility — if your site has never been submitted to Bing, ChatGPT has no reliable way to retrieve it, regardless of how strong your Google SEO is.
Does being indexed in Bing guarantee ChatGPT will name my practice?
No. Being indexed in Bing is the floor, not the ceiling. In our June 2026 Columbus scan, the 21 practices whose Bing data we could read were all indexed — with page counts from about 50 to more than 145,000 — and ChatGPT still named none of the 58 practices we checked.
Can anyone guarantee my dental practice will be recommended by ChatGPT?
No agency can guarantee a specific ChatGPT recommendation, and we don't either. What we guarantee instead is the work itself — a complete, documented technical setup, the full optimization work in your plan, and honest before/after reporting — plus our own money: if your practice hasn't been named by at least two of four engines in at least one agreed question within 45 days of confirmed setup, we refund the one-time setup fee in full.
Does Citevio only work on ChatGPT, or other AI engines too?
No. Citevio covers ChatGPT, Perplexity, Gemini and Google AI Overviews. Each pulls from different data sources — Bing's index, Google Business Profile, review platforms, community content — so each gets its own playbook rather than one generic fix.
Does Citevio only work with practices in the cities you scanned?
No. Citevio works with practices anywhere in the United States; the Charlotte and Columbus numbers on this page are from a research scan, not a service area limit. The two real limits are a maximum of three cosmetic or Invisalign practices per state at any one time, and on the Dominance plan, one practice per metro.
What does Citevio's service cost?
Visibility runs $1,400 per month, Authority $2,900 per month and Dominance $5,500 per month, published openly rather than quoted on a call. Every plan runs the same underlying protocol; what changes is how much of the trust and answer-layer work happens each month.
Do I need to rebuild my website to fix these issues?
Usually not. Most of what an engine needs is already on the site — it's either unreadable to crawlers or missing the specific answer a patient asked for. We work with the site you have, and if something genuinely needs to change, we say what and why before touching it.
How long until ChatGPT starts showing my practice after I fix these issues?
Once your pages are indexed in Bing, they can begin appearing in ChatGPT within days to a few weeks. The review and consistency signals that make ChatGPT confident enough to actually recommend you compound over a longer 30 to 90 day window, and no one can guarantee a specific position within that.
