# How to Reduce ACoS on Amazon Ads: 5 Proven Strategies That Work > Learn exactly how to reduce ACoS on Amazon PPC ads with actionable tactics: keyword optimization, negative targeting, listing quality, and bid management. Real steps, not theory. Amazon PPC Strategy # How to Reduce ACoS on Amazon Ads: 5 Proven Strategies That Work Published July 4, 2026 by VEONIB ## Quick Answer To reduce ACoS on Amazon ads, focus on three levers: lower your cost-per-click through smart bid management, improve your conversion rate with better listings and video content, and eliminate wasted spend using negative keywords and search term audits. Most sellers see a 20-40% ACoS drop after implementing all three. If you are running Amazon PPC campaigns and watching your ACoS climb higher each week, you are not alone. A rising ACoS is the single most common frustration among Amazon sellers, and it usually creeps up slowly: a few extra cents per click here, a lower conversion rate there, and suddenly half your revenue is going back to Amazon. The good news is that reducing ACoS is entirely within your control. It does not require a massive ad budget or a team of specialists. It requires understanding where your ad dollars are bleeding and knowing which lever to pull. **Simple Think:** ACoS (Advertising Cost of Sales) = ad spend / attributed sales × 100. If you spend $200 on ads and generate $1,000 in sales, your ACoS is 20%. Every dollar you save on ACoS drops straight to your bottom line. ## 1\. What Reducing ACoS Really Means ACoS is the ratio of ad spend to revenue generated by those ads. When someone tells you to "reduce ACoS," they are asking you to either lower what you pay for clicks or increase the sales those clicks produce. It is a two-sided equation. Many sellers fixate on the spend side and blindly lower bids. That often backfires because cheaper clicks come with lower placement, fewer impressions, and ultimately less revenue. Smart ACoS reduction works both sides of the equation simultaneously. ## 2\. Fastest Ways to Cut ACoS These tactics deliver the quickest results. Implement them this week. - **Audit your search term report.** Download your last 30 days of search term data. Identify terms spending money with zero or low conversions. Add them as negative exact match keywords immediately. - **Pause high-ACoS campaigns.** Any campaign above your breakeven ACoS for 14+ days should be paused or restructured. Do not keep pouring money into losing campaigns out of attachment. - **Switch to exact match.** Broad and phrase matches often trigger irrelevant searches. Exact match gives you control over which queries trigger your ads, reducing wasted clicks. - **Lower bids on poor performers.** For keywords with high ACoS but decent volume, reduce bids by 15-25% rather than pausing entirely. This maintains some visibility while cutting cost. ## 3\. Keyword Optimization for Lower ACoS Keyword optimization is where most ACoS reduction happens. A well-structured keyword strategy can cut your ACoS by half without spending a dollar less on bids. ### Separate Match Types by Campaign Run separate campaigns for broad, phrase, and exact match keywords. This lets you set different bids for each match type and prevents broad match waste from dragging down exact match performance. Exact match usually converts at 2-3x the rate of broad match. ### Mine the Search Term Report Weekly Every week, download your search term report and look for three things: high-spend terms with no conversions (negative them), high-converting new terms (add them as exact match), and terms with ACOS above 60% (lower the bid or pause). ### Use Negative Targeting Ruthlessly Negative keywords are the fastest way to stop wasting money. Add negatives at both the campaign and ad group level. Common negative candidates include "free," "cheap," "diy," "used," and brand names that are not yours. **Pro Tip:** A keyword with a 50% ACoS and $500 in sales is performing better than a keyword with a 20% ACoS and $20 in sales. Do not judge keywords by ACoS alone. Consider the absolute profit contribution. ## 4\. Listing Quality and Conversion Rate Your ACoS is not just a reflection of your ad strategy. It is also a direct reflection of your product listing. If your listing converts poorly, your ACoS will be high no matter how well you manage bids. ### Improve Conversion Rate to Lower ACoS A listing with a 10% conversion rate generates twice the sales from the same ad spend as a listing with a 5% conversion rate. That means your ACoS halves instantly. Focus on these elements: - **Product video:** Listings with professional videos convert 15-30% higher on average. Video shows the product in use, builds trust, and answers questions before they are asked. - **High-resolution images:** Use at least 6 images showing the product from multiple angles, in use, and with clear size references. - **Bullet points and description:** Lead with benefits, not features. Use plain language your customer would use when searching. - **A+ Content:** Amazon A+ Content improves conversion by 5-10% on average. This is a low-effort, high-impact improvement. ### Create Professional Product Videos with VEONIB Listing videos are the single highest-impact improvement for conversion rate.

Bid Management and Budget Strategy Bid management is a balancing act. Bid too high and your ACoS suffers. Bid too low and you lose visibility. The key is dynamic adjustment based on real performance data. - **Use dynamic bids down only.** This strategy lowers your bid for clicks that are less likely to convert, protecting your ACoS from underperforming placements. - **Set placement premiums carefully.** Top-of-search placement typically has higher conversion but also higher CPC. Only bid for top placement on your best-converting keywords. - **Review bids every 72 hours.** Amazon auction dynamics change constantly. A keyword that was profitable at $0.80 bid last week may need a $0.60 bid this week. ## 6\.

Premium brands with high margins can sustain up to 40%, while commodity sellers often need under 15%. The real answer depends on your profit margins. **Can lowering bids reduce ACoS?** Yes, lowering bids reduces ACoS directly by decreasing cost per click. However, aggressive bid cuts can reduce impressions and sales velocity. The goal is finding the sweet spot where bids are low enough for efficiency but high enough for visibility. **How does video content affect ACoS?** Video content significantly improves conversion rates on Amazon, which directly lowers ACoS. Listings with professional product videos see 15-30% higher conversion rates, meaning fewer clicks are wasted and your ad spend goes further. **What is the fastest way to reduce ACoS?** The fastest ways to reduce ACoS are: adding negative keywords to stop wasted spend, pausing high-ACoS keywords, launching precise exact-match campaigns, and improving your listing conversion rate. Combined, these tactics can lower ACoS by 20-40% in under two weeks. VEONIB — AI-Powered Ecommerce Video Generator. Turn any product URL into a professional video in 60 seconds.
