How We Built a Healthtech Ad Account to Rs 300 CPL

We started this one with a brand-new ad account. Zero history zero pixel data and zero excuse to hide behind the line "the algorithm just needs time to learn."

That is the version of this story we actually want to tell because it is the hard one. Butterfly Learnings came to us as a healthtech buyer and healthtech buyers do not evaluate an agency on brand awareness or a nice-looking feed. They ask for a cost-per-lead number and a customer acquisition cost they can defend to their own management. Great creative is not a line item anyone signs off on.

Why We Did Not Pitch Creative First

Most agencies open a healthcare pitch with moodboards and ad concepts. We did not.

Instead we rebuilt the account structure from zero starting with how leads were being valued which stage of the funnel we were actually optimising toward and what a qualified lead meant for a healthtech buyer specifically. This was not a generic patient-acquisition template borrowed from a clinic client. Healthtech buyers think in terms of unit economics, not impressions or engagement.

Before a single ad was built we answered three questions. What does a genuinely qualified lead look like for this specific business. Which funnel stage actually determines whether that lead converts. And what number is the client's leadership actually going to hold us accountable to in a review meeting.

The Real Cost Per Lead Nobody Talks About

Most published healthcare cost-per-lead benchmarks understate the real number by three to four times once you account for funnel drop-off no-shows and onboarding. This fully-loaded cost is something most marketing teams never actually calculate because it requires pulling data from sales, operations and finance instead of just the ads dashboard.

We built the account to be honest about that number from week one instead of discovering it in month four when the client's leadership starts asking harder questions.

This decision changes everything downstream. When you optimise toward a shallow definition of a lead you get a low cost-per-lead number that looks great in a report and falls apart the moment sales tries to convert it. When you optimise toward the real, fully-loaded number from day one every subsequent decision in the account gets built on a foundation that can survive scrutiny.

Building an Account Structure That Survives Scrutiny

A healthtech ad account is not judged by a single screenshot of a strong week. It is judged over quarters, across leadership reviews and against a CAC number that someone has to defend internally.

We structured the account around three pillars.

Funnel-stage clarity. Every campaign was mapped to a specific stage of the buyer journey instead of running broad, undifferentiated traffic and hoping the right people converted somewhere along the way.

Lead-quality definitions set before launch. We agreed with the client on what counted as a genuinely qualified lead before optimisation began, not after the first batch of results came in and needed explaining.

Fully-loaded cost tracking from day one. Every reported number accounted for downstream drop-off, no-shows and onboarding costs rather than presenting an inflated top-line lead count that looked good but meant little.

This structure took longer to build than a standard campaign launch. It also meant the numbers we reported in week one were the same numbers that still held up in month four.

The Results

Once the structure was in place the results followed. The account landed at Rs 300 cost per lead with a 10x return on ad spend. Butterfly Learnings scaled to multiple centres on the back of an ad account built to survive scrutiny, not just impress in a screenshot.

Why This Approach Works for Healthtech Specifically

Healthtech buyers are unusually disciplined compared to other verticals because their leadership teams are trained to scrutinise unit economics closely. A generic patient-acquisition playbook borrowed from a local clinic will not hold up against that level of scrutiny, no matter how well it performs on paper in the short term.

Treating customer acquisition cost as the actual product being delivered, rather than as an incidental metric that follows good creative, changes how every part of the account gets built. It means the account structure itself has to prove the number, one verifiable data point at a time, instead of relying on a single strong month to carry the entire narrative.

The Takeaway

Strong creative matters and a well-built account still needs compelling ads to perform. But for a healthtech buyer creative is not the product you are selling them. A defensible, verifiable cost per lead and CAC number is. Build the account structure to prove that number honestly from week one and the results that follow are numbers a client can actually stand behind in their own leadership meetings, not just numbers that look good in a screenshot.
