How does Perplexity find and cite clinics, and what can you actually influence?

A patient in your city asks Perplexity which skin clinic to visit for acne treatment. What decides whether your clinic gets named, and is there anything you can actually do about it? Here is what Perplexity itself says, not what an SEO seller says it says.

How does Perplexity find an answer?

Perplexity does not answer from memory. Its own Help Center says it "searches the internet in real-time, gathering insights from top-tier sources" for every question, then compiles the most relevant parts into an answer with numbered citations linking back to where each fact came from.

1. 1

   Step 1: Reads the question

   Perplexity works out what is actually being asked, including local details like a city or specialty.
2. 2

   Step 2: Searches the live web

   It fetches current pages, not a fixed answer written in advance, gathering from articles, websites and directories.
3. 3

   Step 3: Summarises what it finds

   The most relevant facts are pulled together into one answer, in plain conversational language.
4. 4

   Step 4: Adds numbered citations

   Each answer links to the pages it used, so a reader can open the source and check it directly.

Two crawlers do the fetching: PerplexityBot keeps a search index of the web, and Perplexity-User visits a specific page only when it is needed to answer a live question. Perplexity's own developer documentation says neither one is used to train its underlying AI models, and that a site can block PerplexityBot in its robots.txt file if it chooses to.

What are the shield icons next to some sources?

Some citations in a Perplexity answer carry a small shield icon marked Government, Academic or Trusted. Perplexity's Help Center is specific about what this does and does not mean, and it is the one part of how Perplexity works that almost no clinic-marketing page explains correctly.

In practice this means your own clinic website will almost certainly never carry a shield, and chasing one is not a realistic goal. The labels matter more for the sites Perplexity cites about your clinic, such as a government health directory or a well-known publisher. A directory or review site that already carries a Trusted label is a more useful place to be listed correctly than a new page on your own site written only to look "AI-friendly".

How is Perplexity different from Google and ChatGPT?

All three now show AI-written answers, but they are built differently, and each documents itself differently too. This is the short version; our guide to AI answers for clinics covers Google and ChatGPT in more depth.

The practical difference for a clinic: on Google, claiming and correctly filling in your Business Profile is a direct, well-documented lever. On Perplexity, there is nothing to claim. Your only lever is the same open web that Perplexity already reads, which is also true for ChatGPT.

How accurate are Perplexity's citations?

Better than several other AI search tools, but still wrong a meaningful share of the time. This is not a clinic-specific figure, and no clinic-focused study of this kind exists yet, but it is the clearest sourced data point on how far to trust any AI-cited answer.

The lesson for a clinic is simple: a Perplexity answer that names you, or a competitor, is not guaranteed to be accurate even when it looks confident and cites a source. Always open the cited page yourself before you act on what an AI answer says, about your own clinic or anyone else's.

Which "Perplexity SEO" tips are actually documented?

Search for how to get cited by Perplexity and you will find dozens of confident guides, almost all written by marketing agencies, not by Perplexity. Some of the advice is genuinely useful. Some of it is a specific-sounding number nobody can point to a source for. We checked four claims that keep coming up against what Perplexity itself publishes, and against one independent look at crawler behaviour.

The practical point: a service that promises a guaranteed citation timeline or a guaranteed llms.txt fix is selling something Perplexity does not document. A JavaScript-dependent page is different: it is a real, checkable problem. On a computer, right-click your homepage and choose "View Page Source"; if your address, phone number, fees and hours are not visible there as plain text, a script is likely adding them after the page loads, and Perplexity may never see them. On a phone, ask whoever built or manages your website to check the same thing for you.

What can a clinic actually influence?

Nothing here is Perplexity-specific advice sold by an agency. It follows directly from how Perplexity says it works: it reads the open web live, so the same basics that help Google and ChatGPT also help here.

• The same details, everywhere. Your clinic name, address, phone number and services, written identically on your website, your Google Business Profile and any directory that lists you. Perplexity retrieves from all of these, and disagreement between them is a common reason a real clinic gets skipped.
• A website that states facts in plain text, not only in JavaScript. A page that says your hours, fees and services directly, in ordinary sentences, is easier for Perplexity to quote accurately than a page built mostly of images or a PDF, and this matters even more when a script adds the text after the page loads: PerplexityBot reads a page's raw HTML and does not run JavaScript, so anything added afterwards by a booking widget or script may go unseen. See the check above.
• A presence on the directories Indian patients and Perplexity actually use. Most "get cited by AI" guides are written for the US market and point clinics toward Zocdoc or Healthgrades, which barely exist here. One Indian agency's own test of 4 AI engines (opens in a new tab) found Practo, Google Business Profile, Justdial and Lybrate listings being cited for Indian clinic questions instead. A correct, complete profile on these, not a US directory, is the more useful hour to spend.
• Genuine reviews, not managed ones. Google's own guidance (opens in a new tab) and ASCI's advertising code (opens in a new tab) both treat fake or incentivised reviews as a violation, and a thin or inconsistent review history is unlikely to read as a strong signal to any AI tool either.

None of this guarantees a mention. Perplexity does not publish a ranking formula, and no credible source, including Perplexity's own documentation, claims one exists.

How do I check what Perplexity says about my clinic?

This takes about five minutes on your phone. Do it the same way a patient actually would: as a stranger who does not already know your clinic's name.

If your clinic is missing or wrong, the fix is not a Perplexity-specific trick. It is the same list above: fix your details everywhere at once, and give the open web something plain and correct to find. Run the same kind of check on ChatGPT and Gemini too; our 5-minute ChatGPT check walks through that side.

What should a clinic not do?

• Don't pay for a promised mention or label. Treat any such offer the way you would treat a promise to buy a place inside ChatGPT's answer: with real doubt.
• Don't let your details drift out of sync. A phone number or address that changed on one site and not another is one of the simplest reasons an AI tool skips a real clinic. One Indian agency's own test of 4 AI engines (opens in a new tab) observed this pattern too, though it is that agency's own, non-independent work, so treat it as indicative rather than proof.
• Don't assume a Perplexity answer about you is correct. Run the 5-minute check above every so often, the same way you would check a listing on any directory.
• Don't write pages only for AI tools. A page that states your facts plainly for a patient reading it is the same page that is easiest for Perplexity, Google and ChatGPT to quote.
