How to Lower Your ACoS on Amazon

To lower your ACoS on Amazon, cut wasted ad spend with negative keywords and search-term cleanup, restructure campaigns by intent, improve your listing so more clicks convert, and manage bids and placements to a target ACoS. The mistake to avoid is slashing budgets blindly - that lowers ACoS on paper while costing you rank and total sales.

1. Cut wasted spend with negatives

Pull a search-term report and find terms that spent money but rarely or never converted. Add them as negative keywords so you stop paying for irrelevant clicks. This is usually the single fastest way to bring ACoS down without losing good sales.

2. Restructure campaigns by intent

Separate branded, competitor, high-intent, and research keywords into their own campaigns so you can bid each correctly. When everything is mixed together, you overspend on weak terms and underspend on the ones that actually convert.

3. Improve listing conversion

ACoS is not just an ads problem - it is a conversion problem. Better main images, clearer titles and bullets, strong A+ content, competitive pricing, and more reviews all raise conversion, which lowers ACoS because the same clicks produce more sales.

4. Manage bids and placements

Lower bids on keywords running above your target ACoS, raise them on profitable ones, and adjust placement modifiers. Make changes gradually and give them time - over-cutting bids can drop you off page one and tank sales velocity.

What not to do

Do not pause all ads or cut budgets across the board to force a low ACoS. You will lose rank, organic momentum, and total revenue. The goal is profitable sales, not the lowest possible ACoS number.
