How to scale Google Ads spend profitably for a supplement brand

Scaling a supplement brand is scaling a subscription business. The first order matters less than whether the customer places the second, and that is where supplements trail other subscription categories. The figure above comes from Recharge's subscription data: 86.6% of first-time supplement subscribers completed a first reorder, the lowest of the five wellness categories Recharge compared. After that, Recharge found, subscribers who clear the early reorders stay about as well as any consumable subscriber.

So the work is in two places: getting customers past the first reorder, and only paying to acquire as many customers as your own retention can pay back.

1. Track subscription and one-time orders as separate conversions. Report them separately in Google Ads and in Shopify, so you can see which campaigns bring subscribers and which bring one-off buyers.

2. Set a payback window before you set a target. Decide how long a new customer has to pay back their acquisition cost, such as three or six months, and work out what your own cohorts earn in that window at the subscription price. That figure is the most a new subscriber can cost.

   Illustrative arithmetic with made-up round numbers, not a benchmark.

   Your cohorts earn $48 of margin per new subscriber in the first six months. With a six-month payback window, the most you can pay to acquire one is $48. With a three-month window and $30 earned by then, it's $30.

3. Onboard for the first reorder. Recharge's advice is to use the window before the second order: explain dosing, what results to expect and by when, and why finishing the first supply matters. Every customer who reaches the second order is worth more to every campaign that brought them in.

4. Turn cancellations into skips. Recharge found supplements already have the highest skip rate of the five categories it compared. Offer pause, skip and reschedule at the moment of cancellation, so a customer who needs a break defers an order rather than leaving.

5. Time reminders to when the supply runs out. With a cadence of about 30 days, Recharge recommends a nudge just before the product runs out, letting the subscriber confirm or adjust the next order in one step.

6. Stay inside Google's healthcare policies. Google Ads restricts health claims and some supplement ingredients. Check ads and landing pages against its healthcare and medicines policies before scaling, because a disapproval mid-push stops spend on your best campaigns.

7. Scale the cohorts that renew. Each month, compare reorder rates for customers acquired by each campaign. Move budget toward the campaigns whose customers stay, even if their first-order ROAS is lower. A campaign with a modest first-order ROAS but subscribers who keep reordering can be the most profitable one in the account.

What this looks like month to month

For context, Triple Whale's Google Ads benchmarks put the median health and wellness brand's cost per acquisition at $34.76, up 13.36% on the previous year. Your own ceiling comes from step 2, not from the median. Review first-order POAS weekly and cohort reorder rates monthly, and let the cohorts decide where budget goes.
