How to Reduce Amazon PPC Costs in 2026: Proven Strategies That Actually Work

Amazon PPC costs continue to rise across competitive categories, which means every wasted click puts more pressure on profitability. The fastest path to improving returns is not cutting every bid—it is eliminating wasted spend before it reaches your budget.

The solution is not to cut every campaign. The real solution is to eliminate wasted spend, protect profitable traffic, and improve your campaign structure.

To reduce Amazon PPC costs, start with the areas that waste the most budget:

• Poor campaign structure
• Irrelevant search terms
• Overpriced bids
• Broad match waste
• Weak placement control
• Low-converting ASINs
• Unclear ACoS targets

For a broader overview of account setup before cost optimization, read SalesDuo’s Amazon PPC campaign strategy guide.

This guide shows you how to reduce Amazon PPC costs without cutting the campaigns that continue to drive profitable sales.

1. Fix Your Campaign Structure First to Lower CPC

Campaign structure best practices to lower CPC start with separating discovery, branded, non-branded, competitor, and exact-match campaigns. A messy structure makes it hard to see which campaigns are wasting money and which ones deserve more budget.

If auto, manual, branded, non-branded, and competitor campaigns are mixed together, your data becomes unclear. You may lower bids on good keywords or keep funding campaigns that are not converting.

A clean structure gives you better control over CPC, ACoS, budget, and keyword performance.

Separate Auto and Manual Campaigns

Auto campaigns should be used for discovery. Manual campaigns should be used for control.

Auto campaigns help you find search terms that shoppers are already using. But once a search term starts converting, move it into a manual campaign.

This gives you better control over:

• Bids
• Match type
• Daily budget
• ACoS target
• Keyword-level performance

Auto campaigns should not hold your best keywords forever. Move winners into manual exact campaigns and manage them closely.

Separate Branded, Non-Branded, and Competitor Campaigns

Branded, non-branded, and competitor keywords behave differently. They should not share the same budget.

A customer who searches for your brand name already knows your product. That traffic usually converts better. A customer searching for a generic category term is still comparing options. A customer searching for a competitor brand needs even more convincing.

Each campaign type should have its own bid range and performance goal.

Branded searches usually come from shoppers who already know your product, so they often behave differently from broad category searches. If both sit in the same campaign, strong branded results can hide weak non-branded performance. Separating them helps you see where spend is working, where it is leaking, and how much you should bid for each type of traffic.

This structure makes it easier to see what is working. It also prevents strong, branded performance from masking weak generic or competitor campaigns.

Use SKAGs for Top Keywords

Use single keyword ad groups for your most important keywords. These are often called SKAGs.

SKAGs work best for proven exact-match keywords with consistent traffic and conversion data. Applying them to every keyword can create unnecessary complexity and make budget management harder, especially for low-volume search terms.

A SKAG assigns a single keyword to its own ad group. This helps you better control the bid, budget, and performance of that keyword.

Do not use SKAGs for every keyword. Use them only for proven keywords that already have:

• Steady sales
• Strong conversion rate
• ACoS near your target
• Enough data to justify separate control

This helps reduce wasted spend by keeping your best keywords separate from weaker ones.

For a broader setup process, read SalesDuo’s guide to Amazon PPC campaign strategy.

2. Negative Keyword Strategy: The Fastest Cost Reduction Available

The quickest way to reduce wasted Amazon PPC spend is to stop your ads from appearing for searches that are unlikely to convert. Negative keywords help filter out those low-value clicks before they use up your budget.

Lowering bids can reduce spend, but it can also reduce sales if you lower bids on good keywords. Negative keywords are safer because they remove waste while keeping useful traffic active.

Start by reviewing your Search Term Report every week.

Review Search Term Reports Weekly

Your Search Term Report shows the actual searches that triggered your ads. This report is one of the best places to find wasted spend.

Look for search terms with:

• Clicks but no sales
• High spend and low orders
• Poor ACoS
• Low relevance
• Terms that belong in another campaign

Example:

If you sell a premium glass food container and your ad shows for “cheap plastic lunch box,” that search may bring clicks but poor sales. Add it as a negative keyword.

Pre-Populate Negatives Before Auto Campaigns Launch

Do not wait for wasted spend data before adding negatives. Before any auto campaign goes live, add a seed list of obviously irrelevant terms based on your product category. If you sell premium kitchenware, add "cheap," "free," "used," "DIY," and "replacement" before the campaign's first day. This prevents paying for traffic you already know will not convert.

Use Negative Exact and Negative Phrase Correctly

Use negative exact when one specific search term is wasting money.

Example:

If “plastic lunch box with lid” gets clicks but no sales, add that full term as a negative exact.

Use a negative phrase when a full phrase pattern is clearly irrelevant.

Example:

If your product is not plastic, you may add “plastic” as a negative phrase. But use this carefully because it can block many searches at once.

A simple rule:

Use negative exact for performance problems. Use negative phrases to clarify relevance problems.

Build Negative Keyword Lists Across Campaigns

Some negative keywords should apply across many campaigns.

If you sell premium-priced products, search terms such as “free,” “used,” or “cheap” often attract shoppers who are unlikely to make a purchase. When appropriate, add these terms to a shared negative keyword list to help prevent unnecessary ad spend.

In many Amazon accounts, irrelevant search terms helps reduce avoidable clicks and makes campaign cleanup easier to measure over time. The exact impact varies by category, competition level, and campaign structure. 

That is why the negative keyword strategy should come before major bid cuts. It removes bad traffic without hurting your best keywords.

3. Bid Reduction Without Losing Impressions

Bid cuts should be based on campaign data, not assumptions. Reducing every bid may lower your spend for a short time, but it can also limit impressions for keywords that are still driving profitable sales.

Instead, review ACoS, CPC, conversion rate, and placement performance before changing bids. The aim is to reduce spend on low traffic keywords while keeping high-performing, sales-driving keywords visible.

Use the ACoS Bid Reduction Formula

Use this formula when a keyword is getting sales but has an ACoS above your target:

New bid = Current bid × (Target ACoS / Actual ACoS)

Use the same format for both ACoS values. For example, use either percentages (25 and 50) or decimals (0.25 and 0.50), but do not mix formats. Apply this formula only after a keyword has generated enough clicks and sales to provide reliable performance data.

Example:

If your current bid is $1.50, your target ACoS is 25%, and your actual ACoS is 50%, the new bid should be:

$1.50 × (25 / 50) = $0.75

This gives you a clear bid adjustment based on actual performance.

You can also calculate a keyword-level ceiling bid directly using the margin:

Breakeven bid = Conversion Rate × Sale Price × Profit Margin

Use conversion rate and profit margin as decimals.

Example:

• Conversion rate = 10% = 0.10
• Sale price = $40
• Profit margin = 30% = 0.30

Breakeven bid = 0.10 × $40 × 0.30 = $1.20

Any bid above $1.20 would exceed the profit available from that sale.

Use this formula carefully. If a keyword supports a launch or ranking push, you may not want to cut the bid too quickly. But for mature campaigns, this formula helps bring spend closer to your profit target.

Reduce Placement Modifiers Where ACoS Is High

Amazon ad placements do not perform equally.

Top of search may cost more, but it can also convert better. Product pages may cost less, but the buying intent may be weaker. Rest of search can vary by product and category.

Check placement reports before reducing bids.

Do not blindly chase the cheapest CPC. A cheap click is still expensive if it does not convert.

Set Keyword-Level Bid Tiers

Not every keyword deserves the same bid.

Group keywords into simple performance tiers.

This keeps spending focused on keywords that help sales and reduces waste from weaker terms.

For a full process, read SalesDuo’s Amazon PPC bid management workflow.

4. Match Type Optimization: Narrow Spend to High-Intent Queries

Match type optimization reduces PPC costs by reallocating spend to searches with stronger buying intent. Broad match is useful for research, but it can become expensive if it is not controlled.

Broad match can uncover valuable search terms, but it can also generate traffic that is less targeted than phrase or exact match. For that reason, broad match should primarily be used for discovery campaigns with controlled budgets and weekly search-term reviews.

A practical threshold is to review any broad-match search term once it has enough clicks or spend to make a decision. If it has spent near your target cost per order without producing a sale, lower the bid, add it as a negative, or move it into a cleaner campaign for testing.

Move Winning Broad Terms Into Exact Match

When a broad match campaign finds a converting search term, move that exact search term into a manual exact campaign.

Example:

This gives you better bid control. You are no longer paying for a wide group of searches when one specific search term has already proven itself.

Moving proven search terms from broad match into exact match campaigns often improves efficiency by giving sellers greater control over bids, budgets, and keyword targeting. In many cases, exact-match terms also convert more efficiently than their broad-match counterparts.

Use Phrase Match as the Middle Step

Phrase match is useful when you want more control than broad match, but still want to find close variations.

Use phrase match for keywords that show intent but need more testing. Once a phrase-match search term gets enough sales, move it into an exact match.

Keep Broad Match on a Tight Budget

Broad match should not control most of your spend.

Use broad match with:

• Lower daily budgets
• Lower default bids
• Weekly search term reviews
• Strong negative keyword lists
• Clear pause rules

This allows broad match to find new opportunities without draining the account.

5. Dayparting: Reduce Spend During Low-Converting Hours

Dayparting helps reduce PPC cost by lowering spend during hours when shoppers click but do not buy. The goal is to save budget during weak hours and move it toward stronger buying periods.

Not every hour converts the same way. Some products sell better in the evenings, on weekends, or during lunch breaks. Others waste the budget overnight.

Use your own hourly data before making changes.

Find Low-Converting Time Windows

Use Amazon Marketing Stream, third-party automation platforms, or hourly performance data to identify when campaigns spend heavily but convert poorly. Amazon Marketing Stream provides near-real-time hourly performance metrics through the Amazon Ads API and may require integration through a supported tool or platform.

Look for time blocks with:

• High clicks and low orders
• Higher ACoS than average
• High CPC without better conversion
• Budget running out before peak hours

For many brands, the midnight to 6 a.m. window is a good time to review first. But this depends on category, audience, and marketplace.

Use Budget Rules to Control Spend

Amazon does not provide native dayparting controls for every campaign type. Most advertisers implement time-based bid and budget adjustments using API workflows, automation tools, or third-party PPC platforms.

A practical starting point:

If overnight conversions consistently underperform compared to the rest of the day, test modest budget reductions during those hours and measure the impact over a two-week period before making larger adjustments.

The goal is not to completely shut off ads. The goal is to stop low-quality traffic from using the budget that could be used more effectively later in the day.

Reinvest Savings Into Better Hours

Do not cut, spend, and leave the money unused.

Move saved budget into:

• High-converting hours
• High-performing campaigns
• Proven exact-match keywords
• Branded defense campaigns
• Strong product launches

This is also useful around Prime Day, Black Friday, Cyber Monday, and holiday periods. During seasonal events, increase budgets only for campaigns that already perform well.

After the event, reset bids and budgets toward normal levels. Then pull the Search Term Report within 48 hours to find new winning terms and remove wasted event traffic.

6. Set ACoS Targets by Campaign Goal

You cannot reduce Amazon PPC costs properly without knowing your ACoS target. Each campaign should have a target based on its goal, margin, and role in the account.

A launch campaign should not be judged the same way as a branded campaign. A competitor campaign should not be judged the same way as a ranking campaign.

Start with your break-even ACoS.

Calculate Break-Even ACoS First

Break-even ACoS tells you the highest ACoS you can afford before ads start eating profit.

Break-even ACoS = Profit margin before ads

If your product margin is 30%, your break-even ACoS is 30%.

That means a campaign with ACoS above 30% may be unprofitable unless it supports a clear growth goal, such as launch, ranking, or repeat 

purchases.

Use Different ACoS Targets by Campaign Type

Different campaign types need different targets.

This prevents you from cutting the wrong campaigns.

For example, a branded campaign with 8% ACoS and a generic campaign with 35% ACoS do not mean the same thing. Their traffic, intent, and job are different.

Track TACoS Alongside ACoS

ACoS only shows ad-attributed sales. TACoS compares ad spend to total sales, including organic.

TACoS matters more than ACoS alone when a campaign is supporting organic ranking. If a campaign runs at a higher ACoS while TACoS remains stable or improves, it may indicate that advertising is supporting broader account growth. However, TACoS alone cannot prove that advertising caused the organic lift, so it should be evaluated alongside keyword rankings and total sales trends.

If a campaign spends heavily, converts poorly, and does not improve organic sales, it needs to be fixed regardless of what TACoS shows.

7. Use Automation to Enforce Cost Limits at Scale

Automation helps reduce PPC costs when manual campaign checks become too slow. It can pause waste, control budgets, and flag poor-performing search terms faster than manual review alone.

But automation should not replace strategy. It should enforce the rules your PPC team has already set.

Use automation to control spend at scale, not to blindly manage your account.

Pause Keywords Above ACoS Thresholds

Rule-based automation can reduce bids or pause keywords when their costs exceed a set limit.

Some bid adjustments can be handled through Amazon’s native automation features, while automated pausing, search-term monitoring, and negative keyword workflows often require API integrations or third-party PPC platforms.

Examples:

This helps stop slow budget leaks before they become large losses.

Use Portfolio Budget Caps

Portfolio-level budget controls help manage total spend across related campaigns, such as auto, manual exact, branded, and competitor campaigns for the same ASIN. This helps prevent weaker discovery campaigns from consuming budget that should be reserved for proven exact-match or branded campaigns.

Automate Negative Keyword Discovery

Automation can also flag search terms that spend without converting.

For example, a tool can alert you when a search term crosses a spend threshold with no sales. Your team can then decide whether to add it as a negative exact or a negative phrase.

This saves time and keeps search term cleanup consistent.

8. Four More Quick Wins to Reduce Amazon PPC Costs

Reduce Product Page Placement Bids

Product page placement bids should be reduced when they spend heavily but do not convert. These placements can work well for ASIN targeting, but they often need stricter control than top-of-search traffic.

If the top of search runs at 28% ACoS and product pages run at 65% ACoS, your product page modifier may be too high. Reduce the modifier or separate product page campaigns for better control.

Evaluate placement performance only after there is enough click and sales data to make a fair judgment. Acting too early on a small data set can cause you to lower bids on placements that may still become profitable.

Pause Low-Performing ASINs and SKUs

Sometimes the PPC problem is not the keyword. It is the product being advertised.

If one ASIN converts at 0.5% while another converts at 3%, the weaker ASIN can drag up the average ACoS. Pause weak ASINs from shared campaigns and test them separately after fixing price, images, reviews, stock, or offer quality.

Consolidate Duplicate Keywords

Duplicate keywords make performance harder to read. One campaign may get clicks, another may get orders, and another may waste spend.

Keep the keyword where it serves its clearest purpose and provides the best data. Pause or reduce duplicates that do not add value.

Review and Lower Default Bids

Many auto campaigns still run on default bids that were set during launch. Those bids may no longer match the campaign’s current performance.

Use lower default bids in discovery campaigns and reserve higher bids for proven exact-match keywords.

Common Mistakes That Keep Amazon PPC Costs High

Most high PPC costs come from a few repeated mistakes. Fixing these mistakes can reduce waste faster than adding more campaigns.

Here are the biggest problems to check.

Treating Auto Campaigns as Scaling Campaigns

Auto campaigns are useful for discovery, but they should not hold your best keywords forever.

Move converting search terms into manual exact campaigns. Then control bids based on their own performance.

Running Broad Match Without Budget Caps

Broad match can find useful terms, but it can also bring irrelevant traffic.

Use broad match with tight budgets, weekly search term reviews, and strong negative keywords.

Following Suggested Bids Blindly

Amazon suggested bids can be helpful, but they are not your profit target.

Your bids should be based on margin, target ACoS, conversion rate, and campaign goal.

Ignoring Listing Conversion Rate

If your product page does not convert, cheaper clicks will not fix the campaign.

High PPC costs often start with low conversion rates rather than high bids. Weak images, limited reviews, unclear A+ Content, pricing issues, or poor offer quality can all reduce conversion rates and make every click more expensive.

Review:

• Main image
• Title
• Bullets
• A+ Content
• Price
• Reviews
• Coupon or offer
• Stock status

A low-converting listing makes every click more expensive.

Optimizing Only for ACoS

ACoS matters, but it does not show the full picture.

A campaign may have a higher ACoS during launch, but still help organic ranking. Another campaign may have low ACoS but very little growth value.

Use ACoS and TACoS together.

Not Resetting After Seasonal Events

During major shopping events like Prime Day, Black Friday, Cyber Monday, and the holiday season, many sellers increase bids and budgets to capture the surge in shopper demand.

But after the event, reset bids and budgets toward normal levels. Then review the Search Term Report within 48 hours to remove waste and collect new keyword opportunities.

Conclusion: Reduce Amazon PPC Costs by Cutting Waste, Not Growth

The most effective way to reduce Amazon PPC costs is to eliminate wasted spend before reducing profitable traffic.

Start with campaign structure, clean up search terms, add negative keywords, adjust bids using performance data, refine match types, and review placement performance. Then use automation to maintain those controls as your account grows.

The goal is not to spend less everywhere. The goal is to spend less on traffic that does not convert and more on the campaigns that drive profitable growth.

Frequently Asked Questions

What is the fastest way to reduce Amazon PPC costs?

The fastest way to reduce Amazon PPC costs is to stop wasting spend first. Review your Search Term Report, add irrelevant queries as negative keywords, lower bids on high-ACoS keywords, and move proven search terms into exact match campaigns.

What is a good ACoS target to aim for when reducing Amazon PPC costs?

A good ACoS target depends on your profit margin and campaign goal. If your pre-ad profit margin is 30%, your break-even ACoS is 30%. Mature campaigns should usually stay below break-even, while launch campaigns may run at a higher level for a short period.

How do negative keywords help reduce Amazon PPC spend?

Negative keywords help eliminate low-value search traffic by blocking terms that do not match your product or consistently underperform. This allows you to allocate more of your advertising budget to searches that are more likely to convert.

Can I reduce Amazon PPC costs without reducing sales?

Yes, you can reduce Amazon PPC costs without reducing sales by cutting waste rather than profitable traffic. Add negative keywords, lower bids on inefficient terms, reduce weak placements, and protect campaigns with strong conversion rates and profitable ACoS.

What is the difference between reducing ACoS and reducing PPC spend?

Reducing PPC spend means lowering the total amount spent on ads. Reducing ACoS means improving ad efficiency. A campaign can spend more and still improve ACoS if sales grow faster than ad spend.
