Your clinic is spending $12,000 a month on Google Ads. Same budget as last year. Similar keyword mix. Similar landing pages. Same agency. But this quarter, your cost per booked consultation jumped from roughly $280 to $410, and your coordinator is getting fewer qualified calls.
Do not solve that by blindly increasing spend.
The bigger issue may not be your bids, your ad copy, or your agency's weekly optimizations. Google Search changed underneath your campaign. AI Overviews are suppressing click-through rates on informational queries, zero-click searches keep climbing, and Google is simultaneously expanding ad inventory inside AI-generated search experiences. That changes how demand is captured, how patients validate clinics before clicking, and what your landing pages need to do when they finally arrive.
The auction got more expensive while the click pool got smaller
Across industries, the average CPC for Google Ads reached $5.26 in 2025, up about 12.9% YoY, and 87% of industries saw CPC increases (LocaliQ / Search Engine Land, 2025). For medical tourism keywords like "gastric sleeve Tijuana" or "plastic surgery Mexico," we don't have third-party benchmarks isolating those terms specifically. In the 14 bariatric and plastic surgery accounts we manage in Zona Rio (average monthly spend $8,000-$15,000, tracked from Q3 2024 through Q1 2026), CPCs on non-branded search terms increased 18-25% over that period.
At the same time, the search environment is producing fewer outbound clicks. SparkToro and Datos reported that a large majority of Google searches now end without a click to the open web, and BrightEdge reported that search impressions rose nearly 49% YoY while CTRs weakened (BrightEdge, 2025). You can be seen more often and still get less traffic out of the SERP.
That gap widened once AI Overviews expanded across more query types. Semrush found AI Overviews appearing on a growing share of Google results, becoming more common beyond purely informational queries over time. Seer Interactive then measured the performance impact: on queries where AI Overviews appeared, organic CTR fell 61% and paid CTR fell 68% (Seer Interactive, 2025). The term "Great Decoupling" circulated widely in the search industry through 2025 to describe this gap between impressions and clicks. Googlers referenced the dynamic in presentations, though it should be noted this isn't a formal Google designation.
For a Tijuana clinic, this plays out in a specific way. When a patient in Phoenix searches "how much does gastric sleeve cost in Tijuana," Google increasingly shows an AI Overview that synthesizes pricing data from clinic websites, Reddit threads, and medical tourism directories. The patient gets directional pricing without clicking your ad. Your impression counts. Your click doesn't happen. Your budget still gets consumed by the broader campaign. And the patient who does eventually click arrives with price expectations already set by what she read in the AI summary.
Paid search still works. Its job changed.
Paid search is not dying. Google expanded ads in AI Overviews on desktop throughout 2025 and publicly announced testing in AI Mode. Meanwhile, ChatGPT ads reportedly start at $200K with health restrictions that make them impractical for most clinics. Paid search remains a revenue channel. What shifted is where it sits in the patient's journey.
In a pre-AI-search workflow, the ad often introduced the clinic. The patient searched, clicked, landed on your page, and called the coordinator. In 2026, the patient frequently arrives after she has already read an AI Overview, compared clinics across multiple tabs, checked reviews or Reddit, and asked ChatGPT or Perplexity about price, risks, surgeon credentials, or recovery timelines. We cover how patients use ChatGPT to evaluate surgical quotes in our synthetic second opinion guide.
That changes the conversion job of the landing page. Your landing page no longer wins by educating from zero. It wins by confirming what the patient has already learned, correcting bad assumptions without sounding evasive, and proving that your clinic is the safest credible next step.
In the 14 accounts we manage (bariatric and plastic surgery, Zona Rio, $8K-$15K/month, Q3 2024-Q1 2026), we've observed that pages built around "Call for pricing" or generic benefit copy now underperform pages that do three things: show transparent price ranges, display credentials with verifiable sources (CMCPER directory link, cedula profesional lookup), and answer the exact questions AI tools and patients are already asking. We haven't isolated this as a controlled experiment, but the pattern has been consistent across 9 of our 14 accounts over the past two quarters.
Where your budget is leaking
In the accounts we audit, we consistently find three patterns of waste.
Informational queries consuming budget without converting. Queries like "what is gastric sleeve" or "bariatric surgery explained" trigger your ads, but the patient is in research mode. These are the queries most likely to trigger AI Overviews, which means Google increasingly answers them before the click. Adthena's Q1 2026 cross-industry analysis (six industries) found that healthcare AI Overviews were dominated by informational themes (74% News/FAQ content), filtering low-intent users before they reach paid results. In our accounts, we estimate 15-25% of monthly spend goes to informational queries that rarely convert to booked consultations. If your agency celebrates click volume on these terms without showing consultations by query intent, they're reporting activity, not business performance.
Broad match and automation dragging you into bad auctions. Google's push toward AI Max and automated campaign management means the algorithm decides where your ads appear. In our account audits (internal observation, not industry benchmark), 30-40% of search term reports typically show queries unrelated to medical tourism in Tijuana. General health traffic is not cross-border patient demand. The patient who searches "gastric sleeve risks" from Ohio and the patient who searches "gastric sleeve Tijuana consultation" from San Diego are two completely different conversion profiles. Your account may be treating them the same.
Landing pages contradicting what AI already told the patient. If your landing page says "All-Inclusive Package from $3,999" but AI Overviews and Reddit threads have already told the patient the real cost is $5,200-$5,600, your landing page creates immediate distrust. The page doesn't feel incomplete. It feels strategically evasive. That's when the bounce happens. In 6 of our accounts where we aligned landing page pricing with the numbers circulating in AI responses and patient forums, bounce rates on paid traffic measurably decreased over a 60-day tracking window.

Most agencies report CPCs, CTR, clicks, and impression share. Those metrics are not useless. They are incomplete.
The number that matters is cost per booked consultation, segmented by branded vs non-branded, informational vs transactional intent, procedure line, geography, and landing page.
The question that matters:
Is your clinic paying more for traffic that converts later, weaker, or not at all?
If CPC is up 13%, CTR is down, and your landing page is no longer aligned with how patients pre-qualify you through AI search, your cost per booked consultation can deteriorate much faster than top-line account metrics suggest.
In our 14 clinic accounts (Zona Rio, bariatric + plastic surgery, Q3 2024-Q1 2026), cost per booked consultation increased from approximately $260-285 in Q1 2024 to $370-450 in Q1 2026 on a similar budget range. We define "consultation" as a booked appointment confirmed by the coordinator, excluding branded search and PMax campaigns from this comparison. Individual results vary by specialty, keyword mix, landing page quality, and seasonal factors.
A serious agency conversation sounds like this: "Here is which intent buckets still produce booked consultations, here is where AI-heavy SERPs are compressing click-through rate, and here is what your landing pages must change to recover efficiency."
Capture intent that AI already warmed up
The clinics getting the best results from paid search in 2026 are the ones that adapted to where paid search now sits in the journey.
Shift spend toward transactional intent. Stop overfunding loose educational searches. Prioritize terms that indicate action, comparison, or near-term booking: "book gastric sleeve consultation Tijuana," "bariatric surgeon Tijuana schedule appointment," "plastic surgery package Tijuana price." Lower volume, closer to revenue.
Make landing pages confirmable, not just persuasive. A landing page in 2026 should answer: What does this procedure cost here? What is included? Who performs it? What credentials can I verify? What recovery timeline should I expect? If the patient already asked AI those questions, your page should feel like the authoritative confirmation layer, not the first time she's hearing the information.
Get cited in AI Overviews so paid and organic reinforce each other. Semrush found that by October 2025, ads appeared on 25.56% of SERPs that included AI Overviews, up from 5.17% in March. Google separately confirmed expanding ads inside AI Overviews and testing ads in AI Mode. If your clinic's content gets cited in AI Overviews because you have structured pricing data, surgeon schema, and verifiable credentials, your paid ads can appear alongside that citation. You become visible in both the AI answer and the ad slot. For the full AI visibility framework, see our complete GEO playbook.
Use first-party data to tighten your audience. With third-party cookies disappearing, build first-party audiences. Upload past patient email lists for lookalike targeting. Implement server-side tracking for accurate conversion data. Note: match rates vary, consent requirements apply, and this is not a silver bullet. But smaller, qualified audiences at higher CPCs often produce better cost-per-consultation than broad audiences at lower CPCs.
Who should own this inside the clinic
Not just the agency.
This now sits at the intersection of marketing budget, pricing strategy, site content, surgeon reputation, structured data, review management, and conversion operations. In most clinics we work with in Zona Rio, the decision owner is the marketing director or the operations leader who controls commercial performance. Your PPC agency can manage campaigns. It cannot, by itself, fix pricing opacity on your landing pages, missing proof on your credentials page, or the gap between what your site says and what AI tells patients before they click.
Frequently Asked Questions
Should I stop running Google Ads?
No. For most Tijuana medical tourism clinics, Google Ads remains the fastest short-term channel for booked consultations. Shift strategy toward high-intent transactional queries, tighter query control, and landing pages that validate what patients already learned through AI search.
Are ads appearing inside AI Overviews now?
Yes. Google expanded ads in AI Overviews on desktop, and Semrush reported the share of AI Overview SERPs containing ads rose from 5.17% in March 2025 to 25.56% in October 2025.
Is my agency right that CPCs are rising everywhere?
Mostly yes. Average CPCs rose to $5.26 in 2025, up roughly 12.9% YoY, and 87% of industries saw increases (LocaliQ / Search Engine Land). But informational searches affected by AI Overviews are under more pressure than higher-intent transactional searches. A good agency shows the breakdown by query intent, not just the average.
How does AI-generated research affect conversion rate?
It changes what the click means. By the time a patient clicks your ad, she may already have a price anchor, trust concerns, and credential expectations shaped by AI summaries, reviews, and forums. If your landing page feels vague or contradictory, conversion rate drops. If it confirms and adds proof, it converts.
What should I audit this week?
Pull the last 30 days of search terms and sort by spend. Review which queries are informational, which are transactional, which keywords regularly trigger AI Overviews, which landing pages still hide pricing or proof, and which campaigns generate booked consultations rather than just leads. That will tell you whether your budget is buying demand or renting traffic.
Run this audit this week. Open your Google Ads account. Pull the search terms report for the last 30 days. Count how many of your top-spending keywords trigger AI Overviews when you search them manually. If more than half do, your budget is fighting a structural headwind that no amount of bid optimization can fix. The fix starts with what your landing page says, what AI says about you, and whether those two things match.
