Why Repeat Purchase Rate Matters More Than First-Order ROAS

A brand can look highly efficient on a first-order ROAS basis while quietly struggling underneath, if very few of those customers ever place a second order. First-order ROAS is only half the profitability picture.

Repeat customers are dramatically cheaper to serve

A returning customer requires no additional acquisition spend, which means the true margin on a second or third order is almost always significantly higher than on the first, discount-driven purchase.

Low repeat rate often points to a product or experience issue

When repeat purchase rate is persistently low, the fix rarely lives in the ad account. It usually points to something in the product experience, delivery, or post-purchase communication that isn't giving customers a reason to come back.

Track it by cohort, not in aggregate

Looking at repeat rate by acquisition month or channel reveals whether a specific campaign or channel is bringing in customers who behave differently — information that gets hidden in an aggregate, business-wide number.
