Amazon PPC Audit Checklist: 20 Points to Review for Better Performance

Why Every Seller Needs a Regular PPC Audit

Amazon PPC campaigns are not set-and-forget assets. Market conditions shift, competitors adjust their strategies, Amazon changes its algorithms, and your own product catalog evolves. Without regular audits, campaigns that were once profitable slowly degrade as inefficiencies accumulate.

A PPC audit is a systematic review of your entire advertising account to identify areas of waste, missed opportunities, and structural problems. Think of it as a health check for your advertising. Just as you would review your financial statements quarterly, your PPC campaigns deserve the same disciplined scrutiny.

This checklist covers 20 specific audit points organized into five categories: account structure, keyword and targeting performance, bid and budget management, search term analysis, and reporting and measurement. Work through each point methodically, and by the end, you will have a clear action plan for improving your advertising performance.

Category 1: Account Structure (Points 1 through 5)

Point 1: Campaign Organization

Review your campaign naming conventions and overall structure. Every campaign should have a clear, descriptive name that tells you the product, targeting type, and match type at a glance.

Good naming: "YogaMat-SP-Manual-Exact" tells you the product (Yoga Mat), ad type (Sponsored Products), targeting approach (Manual), and match type (Exact).

Bad naming: "Campaign 1" or "Test campaign" tells you nothing and creates confusion as your account grows.

Check that your campaigns are organized logically. Common structures include organizing by product line, by funnel stage (brand, category, competitor), or by match type. The specific structure matters less than consistency.

Point 2: Campaign Type Coverage

Verify that you are using the full range of campaign types appropriate for your products. A healthy account typically includes Sponsored Products for direct keyword targeting and auto discovery, Sponsored Brands for brand visibility and Store traffic (if Brand Registered), Sponsored Display for retargeting and competitor targeting, and at minimum, one auto campaign per major product for ongoing keyword discovery.

If you are only running Sponsored Products, you are missing significant traffic opportunities. Add the missing campaign types to your action plan.

Point 3: Ad Group Structure

Check that each ad group contains a tightly themed set of keywords. Ad groups with dozens of unrelated keywords make optimization nearly impossible because you cannot tell which keywords are driving the results.

Audit check: If any ad group has more than 20 to 25 keywords, it probably needs to be split into more focused groups. If an ad group mixes very different search intents, like "yoga mat" and "yoga blocks," split them.

Point 4: Product Grouping

Review how products are grouped within campaigns. Each advertised product should be paired with keywords or targets that are specifically relevant to that product. Running ten different products in one ad group means they all share the same bid, making it impossible to optimize for each product's unique economics.

Point 5: Portfolio Organization

Amazon allows you to organize campaigns into portfolios with separate budget caps. Check that you have portfolios set up by product line or business unit. This gives you top-level budget control and makes performance reporting cleaner.

Category 2: Keyword and Targeting Performance (Points 6 through 10)

Point 6: High-Spend Zero-Conversion Keywords

Pull a report of all keywords that have spent more than three times your target cost per acquisition with zero conversions. These are your most obvious sources of waste. For each one, decide whether to pause the keyword, reduce the bid dramatically, or add specific search terms as negatives while keeping the keyword active.

This single audit point often uncovers the biggest savings. It is not uncommon to find 10 to 20 percent of total spend going to keywords that have never generated a sale.

Point 7: High ACoS Keywords

Identify keywords where ACoS significantly exceeds your target. Rather than immediately pausing them, consider whether the bid is simply too high. Reducing the bid by 20 to 30 percent may bring the ACoS into line while preserving the sales volume.

Also check whether high-ACoS keywords are driving significant total sales volume. A keyword with 50 percent ACoS but generating 30 percent of your revenue needs careful handling rather than a blunt pause.

Point 8: Low Impression Keywords

Find keywords with very few impressions over the past 30 days. Low impressions usually mean your bid is too low to win auctions or the keyword has very low search volume.

For low-bid keywords worth targeting, increase the bid incrementally. For zero-volume keywords, consider removing them and replacing with higher-volume alternatives.

Point 9: Match Type Distribution

Analyze how your spend is distributed across broad, phrase, and exact match types. A healthy distribution typically looks like 50 to 60 percent of spend on exact match for your proven winners, 20 to 30 percent on phrase match for close variations, and 15 to 25 percent on broad match and auto campaigns for discovery.

If broad match or auto campaigns are consuming the majority of your budget, you are likely paying for a lot of irrelevant clicks. Shift budget toward exact match campaigns for your proven keywords.

Point 10: Product Targeting Review

If you are running Sponsored Display or Sponsored Products product targeting campaigns, review the ASIN-level performance. Check which targeted ASINs are converting and which are not. Remove non-performing targets and look for new high-potential targets based on your competitive landscape.

Category 3: Bid and Budget Management (Points 11 through 15)

Point 11: Budget Utilization

Check whether your campaigns are running out of daily budget. Amazon's campaign status will show "Budget limited" for campaigns that exhaust their daily budget before the end of the day.

If a profitable campaign is budget-limited, you are leaving money on the table. Increase the budget. If an unprofitable campaign is burning through its budget, reduce bids before increasing the budget.

Point 12: Bid Strategy Alignment

Review the bidding strategy for each campaign. Amazon offers "Dynamic bids - down only," "Dynamic bids - up and down," and "Fixed bids." For most sellers, "Dynamic bids - down only" is the safest starting point because Amazon will reduce your bid when it predicts a conversion is unlikely but will never exceed your maximum bid.

"Dynamic bids - up and down" can increase your bid by up to 100 percent for top-of-search placements. This is aggressive and should only be used on campaigns with strong conversion rates and healthy margins.

Check that your bid strategy matches each campaign's maturity and performance. New campaigns should typically use "down only" until you have enough data to justify "up and down."

Point 13: Placement Adjustments

Amazon allows you to adjust bids by placement: top of search, rest of search, and product pages. Pull your placement report and analyze performance by placement.

If top-of-search delivers significantly better conversion rates, consider adding a positive placement adjustment of 25 to 50 percent to increase your visibility in that premium position. Conversely, if product page placements are underperforming, your base bid should account for this since there is no option to bid down for specific placements.

Point 14: Bid Consistency Check

Look for bids that are misaligned with performance. An exact match keyword converting at 15 percent should have a higher bid than a broad match keyword converting at 3 percent, even if they target the same root term. Yet many sellers set identical bids across match types.

Calculate your target bid for each keyword using the formula: Target Bid equals Conversion Rate times Average Selling Price times Target ACoS. Compare this to your actual bid and adjust accordingly. SellerPilot AI performs this calculation automatically, making bid optimization across hundreds of keywords much faster.

Point 15: Day-Over-Day Budget Pacing

Review your spending patterns over the past 30 days. Are there days where spend spikes unexpectedly? Are there days with very low spend? Inconsistent pacing often indicates budget issues, bid changes that were too aggressive, or external factors like deals and promotions affecting auction dynamics.

Category 4: Search Term Analysis (Points 16 through 18)

Point 16: Search Term Harvesting

Review search terms from your auto and broad match campaigns that have generated three or more conversions. These proven terms should be "harvested" into manual exact match campaigns where you can set a specific bid and track performance precisely.

Check that your harvesting process is running regularly. If you have not harvested in the last 30 days, you are missing opportunities to optimize your top-performing search terms.

Point 17: Negative Keyword Gaps

Run the n-gram analysis described in our negative keyword strategy guide. Look for words and phrases that consistently appear in high-spend, low-conversion search terms. Every dollar saved through negative keywords is a dollar that can be redirected to keywords that actually convert.

Point 18: Search Term Relevance Check

Randomly sample 50 to 100 search terms from your broad match and auto campaigns. For each one, ask: "Would a shopper searching this term genuinely want my product?" If the answer is no for more than 20 percent of your sample, your campaigns have a relevance problem that needs to be addressed through tighter keywords, more negatives, or both.

Category 5: Reporting and Measurement (Points 19 through 20)

Point 19: Attribution Window Understanding

Amazon uses a 7-day click attribution window for Sponsored Products and Sponsored Brands, and a 14-day window for Sponsored Display. This means a click today can be attributed a sale up to 7 or 14 days later.

When analyzing campaign performance, make sure you are looking at data that has fully matured. A report pulled for yesterday's performance will be incomplete because attribution has not finished. Always analyze data that is at least 7 to 14 days old for accurate performance assessment.

Point 20: Total Advertising Cost of Sales

Finally, calculate your Total ACoS (TACoS), which is your total ad spend divided by your total revenue including organic sales. TACoS measures how efficiently your advertising supports your overall business, not just the directly attributed sales.

A healthy TACoS typically ranges from 5 to 15 percent for established products. If TACoS is rising while ACoS is stable, it means your organic sales are declining relative to your ad-driven sales, which could indicate an organic ranking problem.

Track TACoS monthly and compare it to your ACoS trend. The goal is for TACoS to gradually decrease over time as your advertising investments build organic momentum.

Running Your Audit: Practical Timeline

You do not need to complete all 20 points in one sitting. Here is a practical timeline.

Week 1: Points 1 through 5 (Account Structure). This is foundational work that makes everything else easier.

Week 2: Points 6 through 10 (Keyword and Targeting Performance). This is where you find the biggest immediate savings.

Week 3: Points 11 through 15 (Bid and Budget Management). Fine-tune your investment allocation.

Week 4: Points 16 through 20 (Search Terms and Reporting). Build ongoing processes for continuous improvement.

After your initial audit, schedule quarterly re-audits to catch drift and new opportunities. Each subsequent audit will be faster because you have the framework in place and only need to check for changes.

A thorough PPC audit is the difference between advertising that drains profit and advertising that builds it. Work through these 20 points systematically, implement the changes you identify, and then measure the impact over the following 30 days. The results will speak for themselves.
