Amazon PPC Audit: The Exact Checklist Our Team Uses on Every Account
Running Amazon ads isn’t the hard part. Running profitable Amazon ads is.
We’ve audited accounts spending $500 a month and accounts spending $50,000 a month. Surprisingly, the problems are usually the same: wasted spend, duplicate keywords, loose campaign structure, and ACoS climbing for no obvious reason.
That’s exactly where an Amazon PPC audit comes in. It tells you what’s working, what’s leaking budget, and what needs fixing before you increase ad spend.
In this guide, we’re sharing the exact Amazon PPC audit checklist our team uses on every account. From Amazon PPC keyword research and negative keyword analysis to bid optimization and campaign structure, this is the framework we use to improve performance without guessing.

Summary
An Amazon PPC audit is a complete review of your advertising account, campaigns, keywords, bids, search terms, targeting, and ACoS performance.
Instead of looking only at spend or sales, a proper Amazon PPC account audit identifies wasted budget, uncovers profitable keywords, improves campaign structure, and creates a roadmap for better Amazon PPC optimization.
Whether you’re launching a new product or scaling an existing catalog, regular audits help keep campaigns profitable and easier to scale.
Key Takeaways
Audits Find Wasted Ad Spend Fast
The biggest savings often come from fixing existing campaigns, not launching new ones.
Campaign Structure Matters More Than Budget
A clean Amazon PPC campaign structure makes optimization easier and improves keyword control.
Negative Keywords Protect Your Budget
Adding Amazon PPC negative keywords prevents ads from showing for irrelevant searches.
Amazon PPC Optimization Is Ongoing
The best-performing accounts are audited regularly, not only when ACoS increases.
What Is an Amazon PPC Audit and Why Does It Matter in 2026?
An Amazon PPC audit is a health check for your advertising account.
Think of it like opening Seller Central and asking one simple question: Where is my ad budget actually going?
A good audit looks beyond impressions and clicks. It checks campaign structure, keyword targeting, bids, placements, search terms, and conversion performance together. Accordingly, you get a clearer picture of what’s driving profitable sales and what’s simply spending money.
In 2026, this matters even more. Amazon’s advertising ecosystem is getting more competitive, CPCs continue to fluctuate, and AI-driven shopping behavior is changing how products are discovered. As a result, campaigns that worked six months ago may already need optimization.
Expert Observation
At Krolog, one pattern shows up in almost every Amazon PPC campaign audit. Sellers often increase budgets when sales drop. However, budget isn’t usually the problem. Campaign structure and keyword quality are.
Amazon PPC Audit Checklist: Where We Start on Every Account
Every account looks different.
- Different products.
- Different budgets.
- Different goals.
The checklist doesn’t change much, though.
Before touching bids or budgets, we audit the foundation. Accordingly, this Amazon PPC audit checklist helps us spot wasted spend before making optimization decisions.
Step 1: Audit Amazon PPC Campaign Structure First
A messy campaign structure makes optimization harder than it needs to be. We usually start by checking whether campaigns are separated by targeting type instead of mixing everything.
A healthy Amazon PPC campaign structure includes:
- Auto campaigns for discovery.
- Manual keyword campaigns.
- Product targeting campaigns.
- Brand or category campaigns when relevant.
If exact, phrase, and broad keywords live inside one campaign, optimization becomes confusing. Split them; it gives you cleaner data and better bid control.
Step 2: Run an Amazon PPC Keyword Audit
Keywords drive the account. Bad keywords drain it.
An Amazon PPC keyword audit looks at every keyword and asks three questions:
- Is it generating sales?
- Is the ACoS profitable?
- Does it still match customer intent?
Keep scaling keywords with profitable conversions. Pause or reduce bids on keywords spending consistently without results.
Expert Observation
One thing we notice often is that sellers keep adding new keywords every week but never clean old ones. Campaigns slowly become crowded, and performance gets harder to read.
Real World Example
Krolog Case Study: How an Amazon PPC Audit Changed Campaign Performance
This isn’t just our checklist on paper. It’s the same audit framework we used for Cantoo City, a Canadian art supplies brand whose Amazon ads were underperforming before partnering with Krolog.
We started with a complete Amazon PPC account audit, reviewing:
- Campaign structure
- Keyword targeting
- Bids
- Search terms.
From there, we restructured campaigns by intent, refined keyword targeting, added negative keywords, and continuously optimized bids based on performance data.
The result was a stronger, more efficient advertising account that helped the brand achieve:
- 400% increase in total sales
- 191% improvement in ROAS trend
- 128% increase in conversion rate
- 106% increase in visitor engagemen
Amazon PPC Search Term Analysis Finds Wasted Spend Faster
Keywords and search terms aren’t the same.
Keywords are what you target. Search terms are what customers actually typed.
That’s why Amazon PPC search term analysis is one of the highest-impact parts of every audit.
What We Look For
| Search Term Pattern | Audit Action |
|---|---|
| High spend, zero sales. | Add as a negative keyword. |
| High conversions, low bid. | Increase bid gradually. |
| Relevant long-tail search term. | Move into an exact-match campaign. |
| Irrelevant customer searches. | Block through negative keywords. |
A good search term report usually reveals opportunities you never targeted directly.
Amazon PPC Negative Keywords Protect Your Budget
If there’s one step sellers skip the most, it’s Amazon PPC negative keywords.
Negative keywords stop Amazon from showing ads for searches that don’t convert.
What Are Negative Keywords on Amazon?
Negative keywords on Amazon are search terms you tell Amazon not to target.
For example, if you’re selling premium leather sneaker cleaner, searches for kids shoe polish or boot repair kit may be irrelevant. Blocking them prevents wasted clicks.
How to Find Negative Keywords for Amazon FBA
During every Amazon PPC campaign audit, we review:
- Search terms with multiple clicks but no sales.
- High-spend search queries with poor conversion rates.
- Irrelevant product categories.
- Duplicate traffic between campaigns.
This process usually reduces wasted spend before increasing budgets.
Expert Observation
Some accounts have hundreds of dollars spent on irrelevant searches because no one reviews search term reports regularly. Adding the right negative keywords often improves ACoS faster than changing bids.
Amazon PPC Bid Optimization Turns Good Campaigns Into Profitable Campaigns
Once campaigns and keywords are clean, it’s time to optimize bids.
This is where most sellers go wrong. They either increase every bid or reduce everything after ACoS goes up. Neither works.
How We Approach Amazon PPC Bid Optimization
We review bids based on performance, not guesswork.
- Increase bids on keywords with profitable conversions and good placement potential.
- Lower bids on keywords with high spend and weak returns.
- Pause keywords that continue spending without sales after enough clicks.
- Review Top of Search and Product Page placement adjustments separately.
The goal isn’t the lowest CPC but profitable visibility.
Monitor Amazon PPC ACoS Alongside Conversion Rate
Amazon PPC ACoS tells you how much you’re spending to generate sales. A useful metric, but never read it alone.
Look at ACoS together with:
- Conversion rate
- Click-through rate (CTR)
- Cost per click (CPC)
- Total sales generated
A high ACoS keyword may still deserve budget if it’s driving strong organic rankings or profitable lifetime value. Context matters.
Expert Observation
We’ve seen sellers pause keywords simply because ACoS looked high for a few days. A better approach is reviewing search term quality and conversion history before making changes.

A thorough PPC audit can uncover wasted spend, weak keywords, inefficient bids, and campaign gaps. Use the right checklist to turn your Amazon ads into a more efficient growth channel.
Common Amazon PPC Audit Mistakes Sellers Make
Even experienced advertisers miss these during an Amazon PPC account audit.
- Scaling Budget Before Optimizing Campaigns: Increasing your budget won’t fix poor targeting or low-converting keywords. Audit campaigns first, then scale the ones already delivering profitable results.
- Ignoring Search Term Reports: Your Search Term Report shows what shoppers actually searched before clicking your ad. Regularly reviewing it helps uncover wasted spend and new keyword opportunities.
- Missing Negative Keywords: Without Amazon negative keywords, your ads keep appearing for irrelevant searches. Adding them reduces wasted clicks and improves campaign efficiency.
- Overlapping Campaign Targeting: Running the same keywords across broad, phrase, and exact campaigns without a clear structure can make your campaigns compete against each other and drive up CPC.
- Never Auditing Old Campaigns: Campaigns launched months ago often keep spending with outdated bids, keywords, and targeting. A regular Amazon PPC audit keeps
campaigns aligned with current performance and market trends.
