Most Amazon ad accounts are quietly leaking money, not because the seller did anything obviously wrong, but because campaigns drift without regular review. An audit finds that leak. This checklist walks you through every area to inspect, using reports you already have, so you can spot wasted spend and fix it, or judge whether it is time to bring in help.
What Is an Amazon PPC Audit?
A PPC audit is a structured review of your advertising account that answers one question: where is money being wasted, and what is the highest-impact fix? It looks at campaign structure, spend efficiency, negative keyword coverage, bid logic, ACoS against margin, placements, and search term harvesting. The result is a prioritized action list, not a vague could-be-better.
Why Audit Your PPC
Amazon's ad auction shifts constantly. Competitors change bids, new search terms appear, and your own data accumulates. Without periodic review, three things happen: negatives stop being added, bids fall out of line with conversion, and budget drifts toward whatever is loudest rather than what converts. An audit resets the account to reality.
The payoff is usually fast. Because the most common problems are wasted-spend problems, fixing them lowers ACoS almost immediately, without cutting the revenue you actually want.
The 7-Point PPC Audit Checklist
Work through each area in order. For each one, the question is simple: is this being done, and is the data healthy? Anything you cannot confidently tick is a lead for wasted spend.
- Campaign structure. Are auto, broad, phrase, and exact campaigns cleanly separated so you can see what drives spend and sales? Tangled structure hides waste.
- Wasted spend. Pull the search term report. Flag every term with meaningful clicks and zero orders. That is money leaking out weekly.
- Negative keywords. Are negatives being added regularly? An account with almost no negatives is almost certainly overspending on irrelevant traffic.
- Bid logic. Are bids tied to conversion data, or set once and forgotten? Look for high-spend keywords above target ACoS that never got adjusted.
- ACoS vs margin. Is ACoS measured against your real break-even, or a generic benchmark? Mature campaigns above break-even without a launch reason are a problem.
- Placements. Check placement performance (top of search, rest of search, product pages). Are modifiers pushing budget toward what actually converts?
- Search term harvesting. Are converting terms from auto and broad being promoted into exact-match campaigns? If not, you are discovering winners and doing nothing with them.
Each of these maps directly to the ongoing routine in our Amazon PPC management guide. The audit finds the gaps; the weekly workflow keeps them closed.
Red Flags to Watch For
- Search terms with 10 or more clicks and zero orders that are still not negatives.
- One giant campaign mixing auto targeting with dozens of manual keywords.
- ACoS consistently above your break-even margin on mature products. If you are unsure of your target, read our Amazon ACoS guide.
- Bids that have not changed in months despite fresh conversion data.
- No exact-match campaigns for your proven, best-converting keywords.
- Ad spend rising while organic rank stays flat (rising TACoS).
DIY vs Professional Audit
A self-audit with the checklist above will surface the obvious waste, and you should do it. A professional audit goes further: it benchmarks your account against similar brands, digs into bid and placement logic, and quantifies the revenue opportunity, not just the problems.
We will review your entire Amazon PPC account, campaign structure, ACoS by campaign, wasted spend, and missed opportunities, and walk you through a clear, prioritized plan in your discovery call, at no cost. Learn more about our Amazon PPC management service.
Frequently Asked Questions
What is an Amazon PPC audit?
An Amazon PPC audit is a structured review of your advertising account to find wasted spend, weak campaign structure, missing negative keywords, mis-set bids, and untapped opportunities. The output is a prioritized list of fixes that lower ACoS and improve return.
How often should I audit my Amazon PPC?
Run a light audit monthly and a deep audit quarterly, on top of your normal weekly optimization. If you have never audited the account, do a full one now.
What are the biggest sources of wasted Amazon ad spend?
The most common are: search terms getting clicks but no orders (missing negatives), broad and auto campaigns running without weekly review, bids set too high on low-converting keywords, and advertising an under-optimized listing that cannot convert the traffic you are paying for.
Can I audit my Amazon PPC myself?
Yes. The checklist in this article walks through every area to review using reports you already have in Seller Central, mainly the search term report and campaign performance data. A professional audit goes deeper on structure, bid logic, and opportunity.
How do I know if my ACoS is a problem?
Compare your ACoS to your break-even ACoS (your profit margin). If a mature campaign runs consistently above break-even without a launch reason, that is a red flag.
