AI citations are the links an AI assistant attaches to its answer to show where a fact came from: the numbered sources in Perplexity, the inline links in ChatGPT, the link cards beside a Google AI Overview. The term also has an academic meaning, citing an AI tool such as ChatGPT in a paper or essay; this page is about the other direction, assistants citing websites. For a medical practice, the useful question is which of your pages an assistant could realistically cite, and for what.
In short: AI citations are the source links an assistant shows with its answer. For general medical questions, assistants tend to cite government and major health sites. A practice's pages earn citations for local, practical facts: services, hours, insurance, costs and what to expect. Clear answers, linked sources, dates and structured data make a page easier to cite.
What an AI citation is
A citation is a link from an AI answer to a page that supports it. It differs from a mention, which is your practice's name appearing in the answer text. You can be mentioned without being cited (the answer names you but links a directory), or cited without being mentioned (your blog post supports a general answer).
Each assistant shows citations a little differently, as its provider documents:
| Assistant | How sources appear |
|---|---|
| Perplexity | "Each answer includes numbered citations linking to the original sources" (Perplexity (opens in a new tab)) |
| ChatGPT search | Inline links to sources; OpenAI's developer docs require inline citations to be "clearly visible and clickable" when web results are shown (OpenAI (opens in a new tab)) |
| Google AI Overviews | Links to supporting information from the web, shown with the summary (Google Search Help (opens in a new tab)) |
| Claude | "Every response includes citations" when web search is on (Claude Help Center (opens in a new tab)) |
The term gets 720 searches a month (DataForSEO keyword difficulty 43), and "how to get cited by ai" gets 70 (Google Ads Keyword Planner data via DataForSEO, US, 12-month average to Sep 2026).

How assistants choose sources
No provider publishes a scoring formula, but their documentation describes the same pipeline: search an index, retrieve pages, write an answer, cite what supported it.
- Google says AI Overviews and AI Mode may run a "query fan-out", issuing multiple related searches, which lets it show "a wider and more diverse set of helpful links" than classic results. A page must be indexed and snippet-eligible to be linked (Google Search Central (opens in a new tab)).
- OpenAI says OAI-SearchBot surfaces websites in ChatGPT's search features, and sites that block it are not shown in ChatGPT search answers (OpenAI (opens in a new tab)).
- Perplexity says it searches the web in real time and gathers information from authoritative sources such as articles, websites and journals.
Independent measurement adds texture. In Pew Research Center's March 2025 browsing data, 88% of Google's AI summaries cited three or more sources, and Wikipedia, YouTube and Reddit were the most-linked sites in both AI summaries and standard results (Pew Research Center (opens in a new tab)).
What a practice's pages can realistically be cited for
Your edge is local, specific and current information that no national site has. This table is an editorial framework, not provider data:
| Patient question | Who is best placed to be cited | Your opportunity |
|---|---|---|
| "What is psoriasis?" | National health agencies, large health systems | Low: link to them |
| "Does Brookside Dermatology take Aetna?" | Your website | High |
| "Cost of a dental crown in Fresno without insurance" | Practices that publish prices or ranges | High, if you publish them |
| "What to expect at a first chiropractic visit at Spine & Joint Clinic" | Your website | High |
| "Best pediatric dentist in Fresno" | Directories, review platforms, practice websites | Medium |
| "Is Dr. Huang accepting new patients?" | Your website, directories | High, if kept current |
Practice names are fictional. The pattern holds across specialties: the more a question depends on your hours, prices, providers or policies, the more likely your own page is the best source.
Making a page citable: clarity, sources, freshness
Use this checklist on any page you want cited:
- Named author and clinical reviewer, with credentials, visible on the page
- Published and last-reviewed dates, updated when the content changes
- Clinical statements linked to MedlinePlus, PubMed or your specialty body
- Local facts in plain text: hours, insurance accepted, services, providers, address
- Answer first: the question as a heading, the answer in 40 to 60 words (see answer engine optimization)
- Structured data that matches the page: practice type, address, hours, phone (see schema markup)
- Readable by search crawlers: not blocked to Googlebot, OAI-SearchBot, PerplexityBot or Claude-SearchBot
- One page per service, so each question has an obvious home
The research behind generative engine optimization points the same way: in that 2023 study, adding citations to credible sources was one of the most effective changes a page could make.
Medfy's rebuilt websites include structured data, and its automated SEO produces researched articles every week, drafted from MedlinePlus and PubMed and approved by the practice.
Tracking when you're cited
You can see more than most practices realize:
- Google: Search Console's generative AI performance report (opens in a new tab) counts impressions whenever links to your site are shown in AI Overviews or AI Mode, broken down by page. It shows impressions only, not clicks or queries.
- Bing and Copilot: Bing Webmaster Tools' AI Performance shows where your content is cited in AI-generated answers across Microsoft Copilot, Bing and select partner experiences. Its Citation Share metric, in preview since June 2026, shows your share of citations for a grounding query (Bing (opens in a new tab)).
- Perplexity, ChatGPT, Claude, Gemini: no publisher dashboard, so run a fixed set of patient prompts weekly and record which pages are linked.
- Your analytics: visits referred by assistants confirm that citations are being clicked.
Expect citations to send modest traffic. Pew found users clicked a link inside a Google AI summary in about 1% of visits to pages with one. In Seer Interactive's (opens in a new tab) analysis of informational queries, brands cited in an AI Overview averaged 0.70% organic click-through in Q3 2025, versus 0.52% for brands that weren't cited. Both are correlations, not proof that citation causes clicks.
Medfy's AI visibility tracking runs those prompt checks weekly across ChatGPT, Gemini, Claude, Perplexity and Google AI Overviews, showing whether you're named and who is recommended instead. To understand what a single summary number can and can't tell you, read our guide to the AI visibility score. The free marketing audit gives you a starting score, and our overview of AI visibility for practices puts citations in context. No one can promise a citation: answers vary by phrasing, location and day.
Frequently asked questions
How do AI assistants decide which websites to cite?
They search an index, retrieve the pages that best match the question, write an answer and link the pages that support it. Google says its AI features use query fan-out and only link indexed, snippet-eligible pages. No provider publishes a weighting formula, but for health topics, answers lean toward authoritative sources with a strong reputation for medical information.
Can a small practice's website be cited by ChatGPT?
Yes, mainly for local and practical questions: insurance accepted, new-patient availability, costs, what to expect and services offered. For general medical questions, national health agencies and large health systems are more likely to be cited. Make sure OAI-SearchBot can crawl your site, answer the question near the top of the page, and keep your facts current.
Do citations in AI answers send traffic?
Some, but less than a top search ranking used to. Pew Research Center found users clicked a link inside a Google AI summary in about 1% of visits to pages with one. Seer Interactive's 2025 analysis of informational queries found cited brands earned 0.70% organic click-through versus 0.52% for uncited brands. A citation also builds trust even when it isn't clicked.
How can I see whether AI cites my website?
For Google, use Search Console's generative AI performance report, which counts impressions when your links appear in AI Overviews or AI Mode. For Copilot and Bing, use AI Performance in Bing Webmaster Tools. For ChatGPT, Perplexity, Claude and Gemini, run the same patient prompts weekly and record which pages each answer links, then watch referral visits in analytics.
