How to scale Google Ads spend profitably for a beauty brand

Beauty is a replenishment category, and that changes how to scale. A campaign that looks unprofitable on the first order can be the best one in the account if its customers come back. A campaign that looks profitable can be buying one-off shoppers with a discount code. The sequence below scales on profit you can measure.

The number above comes from Recharge's subscription data: 97.5% of first-time beauty subscribers completed a first reorder. The same data shows how fast that falls away. Only 6.6% of the cohort reached a sixth reorder, and 20.7% of beauty renewal cycles ended in cancellation. Beauty subscribers reorder about every 42 days, slower than the other categories Recharge compared. These are subscribers only, not every beauty buyer, and your own store will differ.

1. Pick the products that bring customers back. Look at which first purchases lead to a second one within your normal reorder cycle. Those hero products are the ones to fund first. A best-seller that nobody reorders earns its money once. Shopify's returning customer rate gives you the store-wide picture; for a product-level answer, export orders and group customers by the product in their first order, then see who ordered again.

2. Separate new and returning customers. Some returning customers would buy anyway, and Google Ads counts their orders as conversions all the same. Use Google Ads' new customer acquisition goal, which can bid more for new customers or bid only for them, and report new and returning revenue separately.

3. Set acquisition targets from repeat rate you have measured. Work out what an average new customer is worth over a period you can observe, such as six months, using your own Shopify data. That, times your margin after gifts and discounts, is the most a new customer can cost.

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

   A new customer spends $45 on the first order and $90 more over the next six months. At a 55% margin after gifts and discounts, that's $74.25 of profit, so a new customer can cost up to $74.25 and still break even over six months, against $24.75 on the first order alone.

4. Keep promotions out of the scaling test. A code changes conversion rate and margin at the same time, so you can't tell whether the budget or the offer caused the result. Scale on full-price campaigns first, then test offers separately.

5. Scale in small steps. For context, Triple Whale's Google Ads benchmarks put the median beauty brand at a $25.39 cost per acquisition and a $70.24 median order value. Your ceiling comes from step 3, not from the median.

6. Check the cohort, not just the campaign. Each month, look at whether customers acquired during a scaling push came back at the same rate as earlier customers. If they didn't, the extra spend reached less loyal buyers, and the targets from step 3 need to come down.

What this looks like month to month

Review new-customer POAS weekly, and cohort repeat rates monthly. Add budget where new-customer acquisition cost is under the ceiling you worked out and the cohorts are holding their repeat rate. Pull back when either slips.
