BACKGROUND

Why Healthcare eCommerce Doesn’t Scale Like “Normal” Ecommerce

Healthcare eCommerce looks like standard direct-to-consumer retail from the outside. In practice, it behaves very differently — especially inside paid acquisition.

Regulation, compliance constraints, and platform eligibility rules introduce friction at every layer. Google Shopping, which is the backbone of scalable intent capture for most ecommerce businesses, is often unavailable or unstable in regulated categories. When it is available, approvals and policy constraints can turn what should be a growth lever into a months-long bottleneck.

At the same time, healthcare businesses tend to lean on partial or proxy metrics — such as registrations or leads — when purchase tracking isn’t fully reliable. That works temporarily, but it breaks the moment you try to scale. Without consistent purchase tracking, you are not doing performance marketing. You are optimizing blind.

That was the state of this account when I took over in July 2025.

THE PROBLEM

The Account Could Not See Its Own Revenue Clearly

When management began, the account was active and spending, but it was not structurally capable of scaling.

Registrations were being recorded consistently, but purchase tracking was unreliable. As a result, optimization decisions were being made using registrations as a proxy for revenue — a necessary workaround, but not a sustainable one. Merchant Center was not fully set up, and Google Shopping was not live. In a healthcare context, this effectively meant that the channel with the highest purchase intent simply did not exist.

This placed a hard ceiling on growth. Without accurate purchase data and Shopping inventory, the account could increase spend, but it could not do so confidently or efficiently. Scaling at that point would have meant amplifying noise rather than signal.

The priority was clear: before any attempt to grow volume, the foundation had to be rebuilt.

THE TURNING POINT

Fix the Tracking and Feed Before Scaling Spend

The first phase of work was not optimization in the traditional sense. It was infrastructure.

Purchase tracking was repaired so that transactions could be captured consistently and used as the primary performance signal inside Google Ads. This immediately changed the quality of decision-making. Instead of inferring success from upstream actions, the account could now evaluate performance based on actual purchases.

In parallel, Merchant Center was fixed and brought online, allowing Google Shopping to launch. In healthcare ecommerce, this step alone can be the primary blocker to scale. Getting Shopping approved, compliant, and stable unlocked access to high-intent demand that had previously been inaccessible.

Only once those two pieces were in place did scaling begin — and when it did, it was anchored to a real KPI: purchase CPA, with registrations used as a quality and control metric rather than a goal in themselves.

‍

THE SYSTEM

Why CPA Improved While Spend Increased

At a surface level, CPA is a simple ratio: spend divided by purchases. But in practice, it can be decomposed into two controllable forces — the cost to acquire intent and the efficiency with which that intent converts into revenue.

In this account, registrations served as the best observable representation of pre-purchase intent. That made CPA functionally dependent on two levers: cost per registration, and the registration-to-purchase conversion rate.

During the launch phase in July and August 2025, the system stabilized. Cost per registration averaged just over $31, and the registration-to-purchase rate settled around 20%. Purchase CPA during this period was $152.80 — a reasonable starting point, but not yet optimized.

The scale phase, from September through December, told the real story. As budget increased significantly, cost per registration fell by approximately 8.5%, dropping below $28.50. At the same time, the registration-to-purchase conversion rate held effectively flat, remaining just over 20%.

That combination is the cleanest form of scalable performance. Intent was acquired more efficiently without degrading downstream quality. As a result, purchase CPA declined even as volume more than tripled.

RESULTS

Scaling Without Losing Control

Between July 1 and December 28, 2025, the account moved from a stabilized launch phase into sustained scale without losing efficiency. Over this six-month window, total spend reached $434,905, driving 3,054.83 purchases at a blended $142.37 CPA. During the same period, the account generated 14,947 registrations at an average cost of $29.10 per registration, with 20.44% of registrants converting into purchasers.

What makes these results notable is not just the absolute volume, but how performance behaved under scale. As spend ramped aggressively after the initial launch phase, CPA did not inflate. Instead, it improved. From the first two months to the subsequent four months, spend increased by more than 200%, while purchases increased by over 235%, and CPA declined from $152.80 during launch to $139.25 during scale.

To make the progression easier to verify, the most important performance metrics are consolidated below.

The table makes the underlying mechanic clear. CPA improvements were driven primarily by cheaper acquisition of qualified intent, not by sacrificing downstream quality. Registration costs fell by roughly 8.5%, while the registration-to-purchase rate held essentially flat. That is the cleanest form of scalable performance: buying intent more efficiently without degrading conversion.

Performance peaks during the scale phase reinforced this pattern. September delivered the best CPA month of the entire run, producing 572 purchases at $128.85 CPA. November delivered the highest absolute purchase volume, with 683 purchases at $136.99 CPA. These were not isolated anomalies — they were produced by the same system operating under significantly higher budget pressure.

One week in particular illustrates the ceiling enabled by the foundation work. During the week of November 17, 2025, the account generated 194.67 purchases on $19,282 in spend, resulting in a $99.05 CPA, with nearly 24% of registrations converting into purchases. That week was not the result of a one-off tactic or temporary exploit. It was the system functioning at full alignment.

THE HONEST PART

Where Performance Softened

December was weaker than the September–November stretch. CPA rose, and the registration-to-purchase rate declined modestly. In healthcare ecommerce, this is neither unusual nor alarming. Auction dynamics tighten, seasonal behavior shifts, and product mix evolves as the year closes.

What matters is that this was not a structural failure. Purchase tracking remained reliable. Google Shopping stayed live and eligible. Optimization decisions were still anchored to purchase-level data rather than proxies. The system held; the environment changed. That distinction is critical — and it is exactly what a scalable performance foundation is designed to withstand.

Unit Economics and Why the Numbers Work

Estimated customer lifetime value for the business sits in the $400–$600 range. At a blended CPA of approximately $140, paid acquisition operates with meaningful margin and room for optimization.

This headroom is what makes the system durable. The account is not dependent on perfect conditions or narrow thresholds. It has space to absorb volatility, refine efficiency, and continue scaling responsibly over time.

What This Enabled — and What Comes Next

By the end of six months, the business had an acquisition engine it could actually trust. Purchase tracking was reliable. Google Shopping was live and contributing volume. Scaling decisions were tied to purchase CPA, with registrations functioning as a quality signal rather than a vanity metric.

From here, the path forward is straightforward. Short-term work focuses on locking in the efficiency band that drove the strongest months. Mid-term gains come from improving conversion between registration and purchase. Longer-term scaling decisions should be made profit-aware, tightening the feedback loop between paid acquisition and downstream value rather than CPA alone.

Outcome

This account did not scale because of aggressive bidding or clever hacks. It scaled because the elements that actually block growth in healthcare ecommerce were addressed first.

Reliable purchase tracking replaced guesswork. Merchant Center and Google Shopping unlocked real intent. Scaling decisions were tied to revenue, not proxies.

The outcome was 3,055 purchases in six months at approximately $142 CPA, with efficiency improving as the account transitioned from launch into scale.

That is what sustainable performance growth actually looks like in healthcare ecommerce.
