On this page
AI Overviews statistics for healthcare show that Google's AI summaries appear on 48.7% of the page-one Google queries in Conductor's health care set, the highest of the 10 industries it studied (Conductor), and on 89% of the healthcare keywords BrightEdge tracks (BrightEdge). They lean on large health publishers, and they change how often patients click through to the pages below them. This page collects the AI Overviews data healthcare marketers need, with each study's method, so you can see where the numbers agree and where they do not. Curve Compliance helps healthcare brands track how often Google's AI Overviews and other AI answers name them. AI Visibility is a feature in Curve Compliance, and Curve also offers it as a managed service. The managed service is Curve AEO, with a team that handles the strategy and execution for you.
Want to see whether Google's AI Overviews cite your site for the questions your patients search? Book a call to see AI Visibility on your own questions, or to talk about the managed service.
This is one of three deeper roundups that sit under AI search statistics for healthcare marketers. Curve AEO tracks how often AI answers, including AI Overviews, name your brand.
Key takeaways
- Reach is huge. Google says AI Overviews has over 2.5 billion monthly active users (Google).
- Health gets more AI Overviews than most topics. Ahrefs found AI Overviews on 44.1% of medical YMYL queries, more than double the 20.5% rate across all keywords (Ahrefs).
- Clinical questions are nearly all covered. In BrightEdge's tracked set, treatment queries showed AI Overviews 100% of the time and symptom queries 93% (BrightEdge).
- Local provider searches mostly are not. BrightEdge's healthcare data shows few or no AI Overviews on "near me" provider searches (BrightEdge), and across all topics only 7.9% of local searches trigger one (Ahrefs).
- Longer questions trigger more. Health searches of seven or more words triggered AI Overviews 73.9% of the time (WebFX).
- Ranking is not the same as being cited. About 24% of healthcare AI Overview sources also rank in Google's top 10 (BrightEdge).
- Patients trust them more than other results. 37% of patients picked the AI Overview as the part of Google's results they trust most when searching for care, ahead of organic links at 20% (rater8).
How many people see AI Overviews
| What was measured | Figure | Source |
|---|---|---|
| AI Overviews monthly active users (global) | Over 2.5 billion, May 2026 | Google I/O 2026 |
| Google usage for queries that show AI Overviews, U.S. and India | Over 10% increase | |
| AI Mode monthly users | Surpassed one billion, with queries more than doubling every quarter | |
| U.S. adults with at least one Google search that showed an AI summary in a month | 58% of 900 adults, March 2025 | Pew Research Center |
| Online health searchers who have seen AI-generated responses at the top of results | 65% | Annenberg Public Policy Center |
| Recent AI health users who used AI built into web search, such as Google AI summaries | 55% | West Health-Gallup |
Google's usage figure comes from its own comparison of people shown AI Overviews with people who were not, so it is Google's claim rather than an outside measurement (Google). Among recent AI health users, AI in web search (55%) was nearly as common as general chatbots such as ChatGPT or Copilot, at 61% (Gallup).
What it means for healthcare marketers: for many patients, the AI Overview is their first contact with AI health information, whether or not they ever open a chatbot.
How often AI Overviews appear on healthcare searches
Each study counts on a different set of searches, which is why the rates range so widely. Read each one with its method.
| Study | AI Overview rate | What was measured | Source |
|---|---|---|---|
| Conductor | 48.7% (equipment and services 49.2%) | Page-one health care queries within about 21.9 million U.S. Google searches across all 10 industries, September 15 to October 12, 2025 | Conductor |
| WebFX | 51% | 130,070 U.S. health queries, July 2025 | WebFX |
| Ahrefs | 43.0% for Health; 44.1% for medical YMYL queries | 146 million desktop SERPs, September 2025 | Ahrefs |
| BrightEdge | 89% (three-year study); 88% (18-month study of 2,760 keywords) | Tracked healthcare keywords, December 2025 | BrightEdge; BrightEdge |
| Agnoli et al. (preprint) | 96.4% | 3,611 benchmark health questions, September 2026 | arXiv |
| Pew Research Center | 18% (all topics) | Every Google search by 900 U.S. adults, March 2025 | Pew |
WebFX found health had the highest AI Overview rate of any industry in its analysis of 2.37 million U.S. search queries, at 51.6% (WebFX). BrightEdge reports healthcare coverage grew from 59% to 89% over two years in its tracked set (BrightEdge). The 2026 preprint used benchmark questions rather than real search logs, many of them several sentences long, so its 96.4% is not a search-wide rate (Agnoli et al.).
Rates also move. Semrush found AI Overviews on 6.49% of queries in January 2025, 24.61% in July and 15.69% in November. Comparing March with November 2025, it named Health among the industries with the greatest decreases in AI Overview share, though another section of the same page still says Health saw a huge rise (Semrush). Across all industries, BrightEdge saw presence grow from roughly 30% to 48% of its tracked queries over the year to February 2026 (BrightEdge).
What it means: on informational health searches, plan as if an AI Overview will appear. Which keyword set you track decides the rate you will see.
Which health searches trigger AI Overviews
BrightEdge's December 2025 healthcare data shows clinical content near full coverage, and local provider searches near none (BrightEdge).
| Query type or specialty | AI Overview presence, December 2025 | Source |
|---|---|---|
| Treatment and procedure queries | 100% (up from 45% two years earlier) | BrightEdge |
| Pain-related queries | 98% | BrightEdge |
| Symptoms and conditions | 93% | BrightEdge |
| Medical coding (ICD-10, CPT) | 90% | BrightEdge |
| Genetic and genomic / cardiology / urology | 97% / 96% / 96% | BrightEdge |
| Gastroenterology / orthopedics / neurology | 94% / 94% / 89% | BrightEdge |
| Primary care / mental health and behavioral | 74% / 63% | BrightEdge |
| "Near me" and provider-finding queries | 0% (100% two years earlier); 11% in a separate BrightEdge study | BrightEdge; BrightEdge |
Two BrightEdge studies from different dates differ on local searches: its 18-month page shows "doctor near me" and "urgent care near me" type queries at 11% in December 2025 (BrightEdge). Across all industries, Ahrefs found AI Overviews on 7.9% of local searches versus 22.8% of non-local ones (Ahrefs). BrightEdge also reports that self-harm, eating disorder names, crisis terms and addiction queries stayed excluded from AI Overviews in all three years it tracked (BrightEdge).
Query wording matters as much as topic. WebFX found health searches of seven or more words triggered AI Overviews 73.9% of the time, against 35.8% for one or two words. Informational health queries triggered them 66.9% of the time, commercial 45.4%, transactional 35.3% and navigational 14.1%. Queries with a location (such as "dermatologist chattanooga") triggered them 35.8% of the time, against 54.2% for queries with no brand or location (WebFX).
Pew saw the same pattern across all topics: just 8% of one or two word searches produced an AI summary, against 53% of searches with 10 words or more, and 60% of searches that began with question words such as "who," "what," "when" or "why" (Pew Research Center). Ahrefs found AI Overviews on 57.9% of question queries (Ahrefs).
What it means: your condition, treatment and "what to expect" pages compete inside AI Overviews, while "near me" searches still run mostly through the map and local results. Treat them as two jobs. For the AI Mode side, see Google AI Mode for healthcare.
What AI Overviews cite in health
| Domain (health care equipment and services) | AI Overview share of voice | Source |
|---|---|---|
| healthline.com | 5.76% | Conductor |
| clevelandclinic.org | 4.55% | Conductor |
| mayoclinic.org | 4.13% | Conductor |
In pharmaceuticals, biotechnology and life sciences, AI Overview citations were highly fragmented, with Merck Manuals on top at .10%. News content was the most cited page type in health care AI Overviews, with over 46,000 pages cited, ahead of blog pages at just over 36,000 (Conductor).
Across all topics, Pew found 6% of the sources linked in AI summaries were .gov websites, against 2% in standard results. Wikipedia, YouTube and Reddit together made up 15% of AI summary sources and 17% of standard result sources. 88% of AI summaries cited three or more sources, and the median summary was 67 words long (Pew Research Center). In Ahrefs' November 2026 snapshot of U.S. AI Overviews across all topics, YouTube led with 24.5% of citations among the top 50 sources, and Healthline was the top health site at number 13 with 0.7% (Ahrefs).
| Overlap with Google's organic results | Figure | Source |
|---|---|---|
| Healthcare AI Overview sources that also rank in the top 10 | About 24%, the highest of nine industries | BrightEdge |
| All industries, same measure | About 17% | BrightEdge |
| Healthcare AI Overview citations not in the top 100 | 22.5% | BrightEdge |
| URLs cited in AI Overviews that appear in the first 10 results (all topics) | 37.9%, March 2026 | Ahrefs |
| Top five health results cited by the matching AI Overview | 44.4% | Agnoli et al. |
The 2026 audit found AI Overviews overrepresented commercial health publishers such as WebMD and Healthline at the expense of academic and government sources (Agnoli et al.). Freshness helps less here than in chatbots: AI Overviews cite content that is 16 days older than the organic results on average (Ahrefs).
What it means: a top ranking helps but is not enough. Pages that answer one question clearly, cite their own sources and carry clinical review give AI Overviews something to quote. See how to rank in AI Overviews and where AI gets healthcare answers.
What AI Overviews do to clicks
Fewer people click when an AI Overview appears: Ahrefs found it correlates with a 58% lower average click-through rate for the top-ranking page (Ahrefs). The full click data, including what being cited is worth, is in zero-click searches in healthcare.
How accurate health AI Overviews are
The 2026 audit of 3,611 health questions, a preprint not yet peer reviewed, used GPT-4.1 to grade AI Overviews against physician-written rubrics and found they earned 38.2% of available points (accuracy 54.2%, completeness 21.6%). An estimated 56.7% of cited statements were supported by their cited page, and 20.8% of statements were factual claims with no citation. Where a rubric anticipated a specific inaccurate or potentially harmful claim, 22.2% of AI Overviews contained it (Agnoli et al.).
An audit of 1,508 baby care and pregnancy searches, accepted at a peer-reviewed conference, found medical safeguards in just 11% of AI Overviews, and the AI Overview and featured snippet on the same page were inconsistent in 33% of cases (Hu et al.). Google said soon after AI Overviews launched in the U.S. that it found a content policy violation on "less than one in every 7 million unique queries on which AI Overviews appeared," and that for health it "launched additional triggering refinements" (Google). Policy violations are not the same as factual errors.
What it means: patients read these summaries as the answer. Clear, clinician-reviewed pages with named sources give Google better material to quote.
What to do with these numbers
- List the questions that matter. Pick the condition, treatment and "what to expect" questions your patients search, in full sentences.
- Check which ones show an AI Overview. Record whether your site is cited, and which sites are.
- Fix the pages AI reads. Give each page one clear answer near the top, sources, an author and clinical review.
- Keep local listings accurate. Provider searches still run through the map and local results.
- Measure over time. Citations change week to week, so track trends, not single checks. See AI Overview tracking for healthcare.
