How a supplements brand grew Amazon PPC sales 30% in a week without losing ACOS control
A health and wellness supplements brand on Amazon wanted to scale PPC without losing efficiency. In 1 week, PPC sales went from $4,201.17 to $5,464.29 (up 30.1%), by cutting spend on high-ACOS campaigns and scaling only where sales were already following spend, adding roughly $1,263 in incremental PPC sales.

01The challenge
A health and wellness supplements brand wanted to grow Amazon PPC sales, but budget was spread broadly across the account rather than concentrated on what was actually converting.
The risk with most "scale PPC" plays is that sales grow by spending more, not by spending better, and efficiency erodes as a result. This account needed growth that didn't cost its ACOS to get there.
02The approach: The ACOS-Guarded Scale
The ACOS-Guarded Scale is three moves, run in order: cut what isn't working, concentrate on what is, and keep cleaning up waste as you scale.
Cut spend on high-ACOS campaigns
Reduced spend on campaigns running high ACOS and shifted that budget toward targets that were already converting well, instead of letting underperformers keep drawing budget.
Scale only where sales follow spend
Concentrated scaling on the campaigns where sales were already tracking with spend, rather than pushing more budget across the full account and hoping efficiency held.
Keep cleaning as you scale
Continued bid and targeting cleanup throughout, which helped ACOS improve even as PPC sales increased, instead of the two moving in opposite directions.
03The results
One week later, PPC sales moved from $4,201.17 to $5,464.29, a 30.1% increase, adding an estimated $1,263.12 in incremental PPC sales for the week.
Why it worked: the account proved it could grow PPC sales while improving efficiency, not by trading one for the other. Scaling the spend that was already working, rather than spreading more spend everywhere, is what gave the account a healthier, more profitable base to keep growing from.
04FAQ
How do you scale Amazon PPC without hurting ACOS?
Cut spend on high-ACOS campaigns first, then concentrate scaling only on targets where sales are already following spend. On this supplements account, that approach grew PPC sales 30.1% in one week while ACOS improved, instead of the two trading off against each other.
What is the ACOS-Guarded Scale?
A three-step framework: (1) cut spend on high-ACOS campaigns and reallocate it to converting targets; (2) scale only where sales are already following spend, not across the whole account; (3) keep running bid and targeting cleanup throughout so efficiency improves as spend grows.
Why not just increase budget everywhere to grow PPC sales faster?
Spreading more budget across an account, including underperforming campaigns, usually grows sales and ACOS together. This account instead cut the underperformers first, which is what let PPC sales grow 30.1% while ACOS improved rather than worsened.
Does this work for brands outside supplements?
Yes. The underlying mechanic, cut what isn't converting, concentrate on what is, and keep cleaning up waste as you scale, applies to any Amazon account carrying budget on underperforming campaigns, regardless of category.
