Summary

AI Overviews healthcare traffic exposure is now close to total on clinical queries: BrightEdge measured AI Overviews on 100% of treatment and procedure queries in December 2025, up from 45% in 2023, and WebFX found them on 51% of 130,070 health searches. Seer Interactive recorded organic click through rate on AI Overview queries falling from 1.76% in June 2024 to 0.61% in September 2025, then recovering to 2.4% by February 2026. Local provider searches are the exception, dropping from 100% AI Overview coverage to 0%.

AI Overviews healthcare traffic losses are real, measurable and very unevenly spread. Google now writes an answer above the blue links for almost every clinical question a patient types, so the click that used to land on your hospital site often never happens. Your rankings have not moved. Patient behavior has.

This report rebuilds the AI Overviews healthcare traffic numbers from dated, named studies you can open yourself, and it corrects a figure the earlier version of this page got wrong. Click through rates on AI Overview queries fell hard through 2025, then recovered part of the way in early 2026. Both halves matter if you are setting a 2026 healthcare budget.

AI Overviews appear on 100% of treatment and procedure queries and on 51% of all health searches. When one appears, organic click through rate sat at 0.61% in September 2025 against a 1.76% baseline in June 2024, then climbed back to 2.4% by February 2026. Local provider searches now show no AI Overviews at all.

How Many Healthcare Queries Trigger an AI Overview

Almost all of them, once the query turns clinical. BrightEdge measured AI Overviews on 100% of treatment and procedure queries in December 2025, up from 45% in 2023. The exception runs the other way: local and provider intent fell to 0%.

Bar chart of AI Overviews healthcare traffic exposure by clinical query category, 2023 against December 2025

Clinical query categories, 2023 against December 2025

BrightEdge tracked AI Overview deployment across healthcare query categories for 3 years and published the comparison on 24 December 2025.

  • Treatment and procedure queries: 45% in 2023, 100% in December 2025
  • Pain related queries: 58% in 2023, 98% in December 2025
  • Symptoms and conditions queries: 57% in 2023, 93% in December 2025
  • Medical coding queries (ICD-10, CPT): 67% in 2023, 90% in December 2025

Length is no shelter either. WebFX found queries of 7 words or more carried AI Overviews 73.9% of the time, against 35.8% for searches of 1 or 2 words. The long tail clinical page you built to escape competition is more exposed than the head term, not less.

The aggregate rate across 130,070 health queries

WebFX analyzed 130,070 health related queries using July 2025 data and found AI Overviews on 51% of them, roughly double the rate across all industries. The aggregate hides the split that decides your page level exposure.

  • Informational health queries: 66.9%
  • Commercial health queries: 45.4%
  • Transactional health queries: 35.3%
  • Queries carrying a location modifier: 35.8%
  • Brand plus location queries: 25.7%

For context on where this started, Healthline Media reported in July 2024 that 45% of the health queries it tracked returned AI Overviews, and its VP of SEO described that as a dip after Google pulled the feature back. The 2025 measurements show where it settled.

Where Google has pulled AI Overviews back

2 retreats are visible in the record. BrightEdge recorded local and provider intent queries moving from 100% AI Overview coverage in December 2023 to 14% in December 2024 and 0% in December 2025.

Separately, TechCrunch reported on 11 January 2026 that Google had removed AI Overviews from specific liver blood test queries after a Guardian investigation into misleading reference ranges. Google declined to discuss individual removals and said it works to make broad improvements. The signal for healthcare teams is useful anyway: Google will trade coverage away when clinical precision is at stake.

What AI Overviews Do to Healthcare Click Through Rates

Seer Interactive put organic click through rate at 0.61% on AI Overview queries in September 2025, against a 1.76% June 2024 baseline, a 61% fall. Its April 2026 update shows a partial recovery to 2.4%, with queries carrying no AI Overview at 3.8%.

Table of AI Overviews healthcare traffic click through rates from Seer Interactive for 2025 and 2026

The 2024 to 2025 fall

Seer analyzed 3,119 search terms across 42 organizations, covering 25.1 million organic impressions and 1.1 million paid impressions from June 2024 to September 2025, and published the update on 4 November 2025.

  • Organic CTR with an AI Overview: 1.76% to 0.61%, a 61% fall
  • Organic CTR without an AI Overview: 2.72% to 1.62%, a 41% fall
  • Paid CTR with an AI Overview: 19.70% to 6.34%, a 68% fall
  • Paid CTR without an AI Overview: 19.1% to 13.04%, a 32% fall

Read the second line again. Queries with no AI Overview on them still lost 41% of their click through rate over the same period. The squeeze is wider than the feature that gets blamed for it.

The 2026 recovery this report previously missed

Seer’s 2026 update, published 24 April 2026 covers 53 brands, 5.47 million tracked queries and 2.43 billion organic impressions across 2025, plus Q1 2026 actuals. It reports organic CTR on AI Overview queries climbing from a floor of 1.3% in December 2025 to 2.4% in February 2026, while CTR on queries without an AI Overview rose from 2.8% in January 2025 to 3.8% in February 2026.

The gap is still wide, and clinical pages still sit on the wrong side of it. What no longer holds is the claim that healthcare CTR only falls. Any 2026 forecast built on the September 2025 figures alone will understate what a clinical page can earn.

What that looks like on a hospital website

Worked example, not a measurement. Take a clinical section earning 10,000 monthly visits at the 3.8% click through rate Seer records for queries with no AI Overview. Hold impressions and rankings flat, then assume every one of those queries gains an AI Overview and drops to the 2.4% February 2026 rate. The section lands near 6,300 visits. Your own Search Console data beats this model, and the measurement section below shows how to pull it.

Which Healthcare Pages Lose Traffic and Which Hold

Informational clinical content takes the damage. Service and department pages sit in the middle. Local provider searches and branded queries hold, because Google stopped serving AI Overviews on local healthcare intent altogether.

Comparison of AI Overviews healthcare traffic exposure by page type, exposed against shielded

The AI Overviews healthcare traffic picture is not uniform across a hospital site, so a single site wide percentage tells you almost nothing. Split the estate by query intent first.

Most exposed: informational clinical content

Symptom guides, treatment explanations, condition descriptions, recovery timelines and clinical FAQ pages historically carried the biggest share of organic traffic to hospital sites. They are exactly what an AI Overview answers well.

Health publishing shows how far this runs. Sistrix data reported by Press Gazette on 14 May 2026 found AI Overviews in 72% of health search results for major UK news brands between 14 January and 24 April 2026, the highest share of any topic measured, against 5% for football and 7% for puzzles. On results where an AI Overview appeared, the click rate for the first organic listing fell from 27% to 11%.

Moderately exposed: service and department pages

Department pages, service listings and clinical programme pages carry mixed intent. WebFX measured AI Overviews on 45.4% of commercial health queries, well under the informational rate, because patients reaching these pages often already know which hospital they are considering.

Least exposed: local provider and branded searches

A patient typing orthopedic surgeon near me, best hospital in Pune or gynecologist in Mumbai gets a map pack and organic listings, not an AI summary. That makes local work one of the few channels still paying full click value, and it is worth funding deliberately: Google Business Profile completeness, review velocity, local keyword targeting, provider and location landing pages, local schema. Our note on local SEO trends worth acting on covers the basics.

The patient you lose is the one in between. She has not chosen a hospital, she is still comparing procedures, recovery times and providers, and that comparison now happens inside the AI answer rather than on your site.

The Zero Click Problem Behind Healthcare Search

Zero click is the backdrop, not the cause. SparkToro measured 68.01% of United States Google searches ending without a click in the first 4 months of 2026, up from 60.45% in 2024. Health queries sit above that average because they skew informational.

SparkToro published the figure on 9 June 2026 using Similarweb’s desktop and mobile web panel for January to April 2026 in the United States. The panel excludes the Google mobile search app, so it reads browser based search only.

Publisher data points the same way. Press Gazette on 12 January 2026, reporting the Reuters Institute’s Journalism and Technology Trends and Predictions 2026 alongside Chartbeat traffic across more than 2,500 publisher sites, found Google search referrals to publishers down 33% globally in the year to November 2025, and down 38% in the United States.

You will still see Gartner’s forecast quoted as fact. Gartner predicted in February 2024 that traditional search engine volume would drop 25% by 2026 as chatbots took share. Treat it as a forecast made over 2 years ago, not a measurement of what happened.

If clinical impressions are holding while clicks fall, the answer above the link is the likely cause rather than a ranking problem. Our triage checklist for declining organic traffic works through 6 causes in order, the AI traffic share report for 2026 shows how little of that lost traffic AI platforms actually send back, and the vertical breakdown of AI Overview traffic loss puts healthcare next to other sectors.

Getting Cited Inside the AI Overview

Citation is the only position inside an AI Overview that pays. Seer’s April 2026 update reports that being cited delivers 120% more organic clicks per impression than not being cited on the same queries.

Checklist of Google requirements affecting AI Overviews healthcare traffic and AI citation

What Google says you need

Google’s guidance is shorter than most optimization checklists. Its AI features documentation, updated 10 December 2025, states there are no additional requirements to appear in AI Overviews or AI Mode, nor other special optimizations necessary. A page has to be indexed and eligible to show in Search with a snippet.

It also closes the schema shortcut that healthcare teams keep buying. Google writes that you don’t need to create new machine readable files, AI text files, or markup to appear in these features, and that there’s also no special schema.org structured data that you need to add.

What YMYL actually changes for healthcare

Google’s helpful content guidance, updated 10 December 2025, defines YMYL as topics that could significantly impact the health, financial stability, or safety of people, or the welfare or well-being of society, and says its systems give even more weight to content that aligns with strong E-E-A-T on those topics. Trust is named the most important of the 4 signals.

The Search Quality Rater Guidelines, dated 11 September 2025, go further. Pages on clear YMYL topics require the most scrutiny for Page Quality rating, medical information is expected to be consistent with well established expert consensus, and health content that contradicts that consensus in a harmful way earns the lowest rating whatever the publisher’s standing.

That is the healthcare specific part of the job: named clinical authors with credentials a reader can check, dated medical review, sources that survive inspection, and no claim that runs ahead of consensus. Our guide to E-E-A-T for healthcare in AI search sets out how to build that layer.

Does citation work in practice

It does, and upGrowth has measured it outside healthcare. For Vance, a fintech client, AI Overview visibility moved from 12% to 89%, average position from 8 to 1 and monthly organic traffic from 1.8K to 5.6K between March and May 2024. The mechanics transfer to clinical content. The compliance bar does not: a treatment page carries a YMYL burden a payments FAQ never will.

How to Measure AI Overviews Healthcare Traffic Loss on Your Own Site

Search Console now reports part of this directly. The Generative AI performance report shows how many times links to your site were shown in a generative AI feature on Google Search, and Google says it rolled the insights out to all websites worldwide as of 31 August 2026.

The report covers AI Overviews and AI Mode. It counts impressions only, so it tells you where Google surfaces you inside AI answers, not what that surfacing earned. Sites without enough impressions in those features will not see the report at all, which is itself a finding.

  1. Pull 16 months of Search Console data for your clinical folder and chart impressions against clicks separately
  2. Flat or rising impressions with falling clicks is the AI Overview pattern, not a ranking loss
  3. Open the Generative AI report to see which pages Google already surfaces inside AI answers
  4. Segment by page type using the table above, because a 0% exposure location page and a 100% exposure treatment page need different work
  5. Track near me and brand plus location queries as a control group, since AI Overviews barely touch them

The gap between impressions and clicks on clinical queries is the number to take into a budget meeting. Our healthcare GEO timeline sets out what the first 90 days of work against that gap looks like, week by week.

AI Overviews Healthcare Traffic: Questions Hospital Teams Ask

How much AI Overviews healthcare traffic loss should a hospital expect?

It depends almost entirely on page type. BrightEdge measured AI Overviews on 100% of treatment and procedure queries in December 2025, and Seer Interactive put organic click through rate on AI Overview queries at 0.61% in September 2025 against a 1.76% June 2024 baseline. Seer’s April 2026 update shows recovery to 2.4%. Local provider and branded pages show almost no exposure, so a blended site average will understate what clinical pages actually lose.

Are AI Overviews still expanding across healthcare queries?

Coverage of clinical queries is close to saturated rather than still climbing. BrightEdge recorded treatment queries moving from 45% in 2023 to 100% in December 2025, and symptom queries from 57% to 93%. Google has also retreated in places: local and provider intent fell to 0%, and TechCrunch reported on 11 January 2026 that Google removed AI Overviews from specific liver blood test queries after a Guardian investigation.

Do AI Overviews affect appointment bookings or only research traffic?

Mostly research traffic. WebFX measured AI Overviews on 66.9% of informational health queries but only 35.3% of transactional ones, and on 25.7% of brand plus location queries. Patients with booking intent usually search by hospital name or by location, and Google shields those results. The loss sits in the comparison phase, where patients weigh procedures, recovery times and providers before choosing where to book.

Is local SEO still worth funding for hospitals in 2026?

Yes, and the evidence is unusually clean. BrightEdge tracked local and provider intent queries from 100% AI Overview coverage in December 2023 to 14% in December 2024 and 0% in December 2025. Google Business Profile completeness, review velocity, local keyword targeting and provider landing pages therefore still deliver full click through value, because no AI answer sits above those results competing for the click.

Does getting cited inside an AI Overview recover the lost clicks?

Partly. Seer’s April 2026 update reports that being cited inside an AI Overview delivers 120% more organic clicks per impression than not being cited on the same queries. That does not restore pre 2024 volumes for clinical content. It decides which brand keeps the clicks still available, and in healthcare the citation carries trust value even when the patient never clicks through.

What does Google actually require to appear in healthcare AI Overviews?

Nothing special, by Google’s own account. Its AI features documentation, updated 10 December 2025, says there are no additional requirements to appear in AI Overviews or AI Mode and no special schema.org structured data to add. What changes for healthcare is the quality bar: the Search Quality Rater Guidelines dated 11 September 2025 expect medical content to match well established expert consensus and give YMYL pages the most scrutiny.


Your Next Move

If you run marketing for a hospital, a clinic chain or a healthtech platform, the next step is small and specific: measure your own AI Overviews healthcare traffic gap on clinical pages, then decide what share of the 2026 budget moves from ranking work to citation work.

For Curious Minds

Google's AI Overviews have transformed user behavior by directly answering clinical questions, intercepting the click that once led to your website. This is more severe than a ranking decline because your content can be perfectly ranked yet receive no traffic, as patients get their information without leaving the search page. The core challenge is the evaporation of engagement opportunities, not just a shift in position. Data from BrightEdge shows AI Overviews appear on 100% of treatment and procedure queries, meaning nearly all informational patient traffic is at risk. Your strategic response should pivot from a pure rankings focus to a traffic-preservation model. This involves identifying and targeting query types that are less saturated with AI-generated answers, such as local provider searches, which now have zero AI Overview coverage. Explore the full report to understand which content areas are most exposed.
