$2.4M · 19.82% ACoS

The average, defended.

Sub-20% ACoS is two different achievements depending on the spend behind it, and a US pet supplements and wellness account holding it at seven-figure volume is the harder one. At small budgets a clean average is cheap; at this scale every loose search term surfaces in the number within days. The category pulls volume and efficiency against each other, and this account was asked for both at once.

The average was defended term by term. Targeting stayed concentrated on queries that convert, so spend never spread thin across the catalog; branded defense sat isolated from non-branded scaling; search-term reports were read on a weekly cadence, and negative-keyword hygiene trimmed waste before it could pull the number up. Growth was allowed wherever the return stayed inside the ceiling and held back wherever it slipped. Sub-20% at this volume is a state the account was kept in, week after week.

The supplied 2023 US dashboard shows $2.4M in sales and 19.82% ACoS. This historical account-specific record does not establish a universal efficiency benchmark or predict another seller's outcome.
