Why Every Amazon Seller Needs a Third-Party PPC Audit (and a Free Tool to Get Started)

Running Amazon PPC is no longer optional. With rising competition, increasing CPCs, and a crowded marketplace, Amazon sellers and brands rely on advertising more than ever to stay visible, competitive, and profitable.

But here’s the hidden truth: most Amazon accounts leak money without the sellers even realising it.

From irrelevant search terms and poorly structured campaigns to incorrect bidding and a lack of negative keywords, many Amazon PPC setups lose between 15–40% of potential returns due to inefficiencies and missed optimisation opportunities.

This is exactly why regular, third-party Amazon PPC audits are so important.

To make this process simpler and accessible, we’ve launched a free Amazon PPC Audit Tool for sellers and brands:

In just a few minutes, you can understand the key KPIs of your Amazon account, identify wasted ad spend, and uncover growth opportunities—without downloading or analysing complex spreadsheets.

Why a Third-Party Amazon PPC Audit Matters

Many brands either manage their Amazon PPC in-house or rely on agencies. While that’s a good start, there’s one common problem: it’s hard to objectively audit your own work.

A third-party or independent audit brings a fresh, unbiased view of your ad performance and account structure.

1. Fresh Perspective, Zero Bias

When the same team that creates and manages campaigns also evaluates them, certain issues may go unnoticed. A third-party perspective helps you:

• Spot long-standing inefficiencies
• Challenge assumptions about “what’s working”
• See your campaigns the way an expert outsider would

2. Identifying Wasted Ad Spend

One of the biggest benefits of an Amazon PPC audit is finding where your money is silently leaking. An effective audit helps uncover:

• Irrelevant or low-intent search terms are consuming budget
• Keywords with high spend but poor sales performance
• Campaigns with high ACoS and low profitability
• Overlapping or competing campaigns targeting the same keywords

By identifying and cutting wasted ad spend, you free up budget that can be redirected towards high-performing campaigns and keywords.

3. Actionable Optimisation Roadmap

A good PPC audit doesn’t just say “something is wrong”; it shows you what to fix and how to fix it. For example:

• Which campaigns need restructuring or consolidation
• Which keywords deserve higher bids and more budget
• Which search terms should be added as exact keywords
• Which terms should be added as negative keywords
• Which ASINs need better visibility and targeting

4. Alignment With Business Goals

Many Amazon ad accounts are built to “get traffic” rather than to support a business strategy. A PPC audit realigns your campaigns with your goals, such as:

• Improving profitability and lowering ACoS
• Scaling hero products that drive most of your revenue
• Launching and ranking new products more effectively
• Maintaining healthy TACoS (Total Advertising Cost of Sales)
• Strengthening brand visibility on key category keywords

5. Staying Updated With Amazon’s Changes

Amazon regularly updates its advertising features, placements, and reporting capabilities. A third-party audit ensures your strategies stay aligned with:

• New ad types and placements
• Updated best practices
• Evolving marketplace competition

The Importance of Quarterly Amazon PPC Audits

Amazon PPC is dynamic. What worked beautifully six months ago might be underperforming today. That’s why we strongly recommend conducting an Amazon PPC audit at least once every quarter.

1. Early Detection of Performance Drops

Quarterly audits help you catch problems before they become expensive:

• Gradual increases in ACoS
• Declining click-through rates (CTR)
• Lower conversion rates (CVR)
• Rising CPCs with no improvement in sales

Instead of discovering issues after months of wasted spend, a quarterly check-in gives you timely control.

2. Adapting to Seasonal Trends

Each quarter has different buying behaviours—festive seasons, sales events, Prime Day, Q4 spikes, and more. A quarterly audit allows you to:

• Adjust bids and budgets based on seasonality
• Prepare your campaigns for upcoming peaks
• Optimise around the best-selling periods for your niche

3. Continuous Improvement of KPIs

Regular audits help you improve key performance indicators over time:

• ACoS (Advertising Cost of Sales)
• ROAS (Return on Ad Spend)
• TACoS (Total ACoS across overall sales)
• CTR (Click-Through Rate)
• CVR (Conversion Rate)
• Overall profitability

Instead of looking at PPC as a one-time setup, quarterly audits ensure it becomes a continuous optimisation process.

4. Keeping Your Campaign Structure Clean

Over time, PPC accounts tend to become cluttered with:

• Old testing campaigns
• Paused experiments you forgot about
• Duplicate or overlapping ad groups
• Unused keywords and ASIN targets

Quarterly audits give you a chance to clean up and simplify, making your account easier to manage and optimise.

5. Stronger Long-Term Brand Growth

When you consistently review and optimise your Amazon PPC, you’re not just fixing issues—you’re building a strong, scalable advertising engine that supports long-term brand growth.
