How a cancer clinic in Mexico cut Google Ads CPL from $325 to $95 in 60 days.
A cancer treatment clinic in Tijuana was spending real money on Google Ads and getting leads that didn't convert. Within 60 days of rebuilding the landing page around the emotional reality of a patient evaluating international cancer treatment, and restructuring campaigns by keyword intent rather than running everything together, cost per lead dropped 71%, lead volume tripled on the same budget, and the lead-to-consultation rate exceeded 50%.

The Problem
Real ad spend producing leads that wouldn't convert.
The clinic had been running Google Ads for some time but had not done a deep audit or structural rebuild in years. Cost per lead was sitting at $325 to $350. The clinic's team flagged lead quality as poor — too many inquiries from people who weren't the right fit, not enough from patients who were serious about pursuing treatment.
Account structure made it impossible to fix on the surface. One or two ad groups were covering a broad mix of keyword themes. Bidding was set to maximize clicks via manual max CPCs, leaving Google to find conversions however it chose rather than optimizing toward them directly.
The landing page situation compounded the campaign problem. Traffic from Google Ads was going to a page that hadn't been built for conversion. It wasn't slow or broken — it just wasn't doing the work a landing page needs to do when the person reading it is evaluating whether to fly to another country for cancer treatment.
From the Field
“When we audited the account, the keywords looked defensible on the surface. The problem wasn't which terms they were bidding on — it was that "alternative cancer treatment" and "immunotherapy clinic" were sitting in the same ad group pointing at the same page. Those are different patients with different decision frameworks and different trust needs. Mixing them doesn't just hurt CPL. It makes it impossible to build messaging that actually converts either one.”

Audit Findings
Three structural failures driving the $325 CPL.
The keywords weren't bad. The structure wrapped around them was.
Mixed-intent keyword grouping
"Alternative cancer treatment" and "immunotherapy" sat in the same ad group, pointing at the same page. The two audiences think about medicine differently and need fundamentally different messaging. One ad cannot convert both.
Max CPC bidding optimizing for clicks
The account was telling Google to get traffic, not to find patients likely to fill out a consultation form. A click from "what is immunotherapy" cost the same as a click from "immunotherapy clinic accepting patients" — but only one of those becomes a consultation.
Landing page built to inform, not to convert
Generic service descriptions, no named physicians, video testimonials sitting unused, contact form below the fold. A patient evaluating an international cancer treatment journey wasn't being given any reason to take the next step.
Landing Page Rebuild
Rebuilt around the emotional reality of a patient choosing international cancer treatment.
The landing page rebuild was the first project before touching the ad campaigns. Converting more traffic from a broken landing page would have produced higher volume of equally poor leads. The page needed to work before the campaigns were worth scaling.
For a patient traveling internationally for cancer treatment, trust is not a feature — it is the prerequisite for everything else. The page was rebuilt to communicate reliability, compassion, and credibility from the first scroll. Copy acknowledged the weight of the decision without being clinical or cold.

Campaign Architecture
Intent segmentation + conversion-based bidding.
The keyword themes that were collapsed into one ad group got separated into distinct campaigns with distinct ad copy and distinct landing page entry points.
Specific-therapy campaigns
Immunotherapy, targeted cancer therapy, named protocols. Tightest match types. Ad copy emphasizing physician credentials, clinical precision, and outcomes. Highest-intent campaign — produced the best CPL and the strongest downstream consultation quality.
Alternative / integrative campaigns
Patients exploring options outside conventional oncology. Distinct messaging built around patient experience, individualized care, and compassion. Separate landing page section that reckoned with the patient's earlier-decision-stage mindset.
Medical tourism + OON campaigns
Second-opinion seekers and out-of-network patients. Messaging emphasized access, what the evaluation process looks like, and how soon a patient could get a consultation.
Conversion-based bidding
Switched from max CPC to maximize-conversions, then target CPA once the account had 30-50 conversion events. The algorithm started shifting spend toward queries, times, and devices that produced form submissions — not just clicks.

Client Voice
“I think the biggest change has just been consistency. Earlier we'd get a few referrals and have a good month. Now we are having good months and great months — a good month is sort of the floor. That not only has improved our revenue, but our ability to deliver phenomenal care.”

What Carries Over
Four lessons that generalize beyond oncology.
Intent segmentation is non-negotiable in high-consideration medicine
Any specialty where patients arrive at the search bar with meaningfully different beliefs about treatment — oncology, regenerative, mental health — pays a structural tax for mixing those intents in one ad group. Separate the campaigns or accept underperformance.
Rebuild the landing page before scaling the ads
Pushing more spend through a broken page produces more bad leads at the same conversion ratio. The page is where the conversion math compounds — fix it first, then turn the volume up.
Conversion-based bidding requires patience the team has to be coached on
The first 2-4 weeks after switching to maximize-conversions look choppy. Most clinics revert prematurely. Building shared understanding that this is expected — and reviewing weekly, not daily — is part of the engagement, not a footnote.
Video testimonials belong at trust-stall points, not at the bottom
Most clinic landing pages bury video below where 80% of visitors ever scroll. For high-stakes decisions, video is the most persuasive element on the page. Move it to the spots where the patient is most likely to hesitate — right after the treatment overview, right before the form.
If your CPL feels too high
We'll tell you exactly what's structural and what's not.
If your cancer clinic — or any high-consideration specialty practice — is producing leads at a cost that makes the channel feel unworkable, or your team is flagging lead quality as consistently poor, the problem is almost always structural. Book a strategy call and we will audit the account and tell you what we find.

How a multi-location plastic surgery group increased qualified consultations by 510% in six months.
The four-location plastic surgery group was spending $28K/month on Google and Meta Ads with flat consultation volume — the budget wasn't the problem, the system was. We rebuilt campaigns at the procedure level, built four procedure-specific landing pages, and connected tracking to actual booked consultations. Qualified surgical consultations grew 510% in six months at the same ad budget.
How a 14-provider orthopedic group built 120+ monthly consultations and fully absorbed 3 new providers in 8 months.
The practice was adding surgeons faster than referrals could consistently fill schedules. We implemented SEO, Google Ads, landing pages, and conversion tracking tied to booked consultations. Within 8 months, the practice was consistently generating enough patient demand to support the expanded provider team.
How an 11-location med spa group sustained a 3.1× return on ad spend and grew booked consultations by 62%.
The 11-location med spa group had inconsistent results across markets, with each location running different programs and no portfolio-wide standard. We rebuilt the creative with a compliance-first approach, shifted to conversion-objective campaigns, and built treatment-specific landing pages for each market. The group now sustains 3.1x ROAS across all 11 locations with consistent booked-consultation volume.
