Effectively managing Amazon PPC campaigns hinges on understanding the wealth of data available through Amazon Advertising Reports.
From Search Term Reports that reveal high-converting keywords to Targeting Reports that uncover duplicate bids and ROAS insights, each report plays a vital role in shaping smart, profitable ad strategies.
But it’s not always straightforward. Many reports contain discrepancies compared to the ad dashboard due to attribution windows, data latency, and API limitations.
Misinterpreting this data can lead to poor optimization decisions.
In this article, we’ll break down the key Amazon Advertising Reports and explain how to interpret them effectively. We’ll also highlight common mismatches between reports and dashboards and offer tips for reconciling data.
Whether you’re troubleshooting campaign performance or making long-term budget decisions, mastering these reports will give you the confidence to act strategically.
Types of Advertising Reports
Here’s a rundown of all the advertising reports at your disposal.
Search Term Reports
Search Term Reports show you the search terms that your customers used to find your products:
Report includes:
- Keyword targeting
- Keyword Match Type
- Customer search term used
- Sales and conversion rate for that term during a specified period
- Clicks
- Click Through Rate (CTR)
- Impressions
- Cost Per Click (CPC)
- Spend
How to use this report:
- Harvest the search terms with the best conversion rates.
- Identify search terms with poor conversion rates, impressions & CTR. You can then use these search terms as your negative keywords.
Target Reports
- Targeting reports show you every keyword, ASIN, and category that you’re bidding on. Plus, they show you what kind of match types you’re using for auto-campaigns.
- Targeting reports show you every keyword, for every campaign, within your account, making it incredibly simple to identify duplicate keywords.
- This report is the only report where you can see your Return on Ad Spend (ROAS).
Advertised Product Reports
- Advertising Product Reports show you all of your ASINS and SKUs, by campaign and ad group, that are winning the Buy Box and are being advertised.
- They show you which products are getting impressions.
- They allow you to identify and highlight your best-performing products quickly.
Placement Reports
- Placement Reports give you a view of your performance-by-ad-placement data for every campaign.
- These reports also offer an account-wide view of campaign performance.
Purchased Products Reports
- Purchased Products Reports show only the keywords (not the search terms) that were attributed to the purchase of that product.
Performance Over Time Reports
- The Performance Over Time Report only provides you with clicks, CPCs, and total spend.
Campaign Report
- The Campaign Report provides a high-level overview of your campaign performance, including metrics like spend, clicks, impressions, and sales.
- It helps you compare performance across campaigns and optimize budgets or strategies accordingly.
Budget Report
- The Budget Report tracks your ad spend against your allocated budget for each campaign.
- It highlights pacing (e.g., under/overspending) and helps ensure you’re maximizing your budget efficiency.
Search Term Impression Share Report
- This report shows the percentage of impressions your ads received compared to the total available impressions for targeted search terms.
- It helps identify missed opportunities due to low bids or poor ad rank.
Gross and Invalid Traffic Report
- This report flags clicks or impressions that Amazon suspects are invalid (e.g., accidental clicks or bot traffic).
- It helps you audit ad spend and dispute discrepancies.
Category Benchmark Report (Sponsored Brand)
- Unique to Sponsored Brands, this report compares your campaign performance (e.g., CTR, conversion rates) against aggregated, anonymized data from similar advertisers in your category.
Attributed Purchases Report (Sponsored Brand)
- Shows purchases attributed to Sponsored Brand ads, including new-to-brand metrics. It helps measure brand growth and campaign effectiveness.
Matched Target Report (Sponsored Display)
- For Sponsored Display campaigns, this report lists the products, categories, or audiences your ads matched to, along with performance data.
- Useful for refining targeting.
Pricing Transparency Report (Sponsored Display)
- Details how your product’s price competitiveness (compared to competitors) impacts ad placement and performance in Sponsored Display campaigns.
Conversion Path Report (All Campaigns)
- Tracks the sequence of touchpoints (e.g., clicks, impressions) leading to a conversion. Helps understand the customer journey across multiple ads.
Amazon Attribution Reports
These reports measure off-Amazon marketing impact (e.g., social media, email) on Amazon sales.
Includes:
- Campaign Report: Performance of external campaigns driving Amazon sales.
- Keyword/Creative Report: Effectiveness of specific keywords or ad creatives.
- Promoted Product Report: Sales driven by promoted products.
- Brand Halo Reports: Measures how campaigns lift sales for non-promoted products in your brand.
Pro Tip: Some advertising reports have a limited timespan of 60/90 days. Meaning, you should set reminders to download them regularly so that you can retain all of your historical data.
Notable Data Discrepancies Between Reports & Dashboard
Sponsored Products
- Search Term Report: Discrepancies in impressions (and sometimes clicks) still occur between the report and dashboard due to latency in data processing or attribution logic. Spend and sales data typically align.
- Targeting/Placement/Campaign Reports: Generally accurate vs. the dashboard, but minor delays (24–48 hours) may occur for real-time metrics like impressions.
Sponsored Brands
- Search Term Report: Differences in impressions, clicks, and spend remain common, as Sponsored Brands attribution windows (e.g., 14-day click/14-day view) can cause mismatches with the dashboard’s snapshot.
- Targeting Report: Usually reliable, but new-to-brand metrics may lag.
Sponsored Display
- Matched Target Report: Occasionally shows discrepancies in audience/category attribution due to Amazon’s dynamic retargeting.
Third-Party Software
API-driven tools (e.g., Sellics, Pacvue) still face sync issues with Amazon’s data, especially for:
- Impression share (delayed or estimated).
- Attributed sales (varies by attribution model).
- Invalid traffic (third parties may not reflect Amazon’s internal filters).
Why This Happens
Amazon’s system prioritizes dashboard data for real-time estimates (updated hourly) but reports for finalized data (processed daily/weekly).
Common Causes
- Time-zone differences in cutoff times.
- Attribution windows (e.g., a dashboard click counted today may shift to "no sale" in tomorrow’s report).
- Amazon’s ongoing API changes.
Recommendations
- Trust reports for historical decisions (e.g., optimizations).
- Use the dashboard for pacing/troubleshooting.
- Audit third-party tools against Amazon’s Business Reports for critical metrics like ACOS.
My AMS Sales Report Data Doesn’t Match up to Amazon COGS Data
Discrepancies between Amazon Advertising (AMS/PPC) sales reports and Vendor Central COGS data (ARA reports) are normal but often misunderstood.
Here’s why they differ and how to interpret them:
Common Causes of Mismatches
- Cancellations/Returns: AMS reports remove cancelled orders after 72 hours; ARA may reflect them temporarily.
- Brand Halo Effect: AMS may credit ads for sales of non-advertised ASINs (e.g., Sponsored Brands), while ARA shows all COGS.
- 3P Seller Sales: Sponsored Brands include 3P sales in ad reports, but ARA excludes them unless you’re the vendor.
- Timing Lags: AMS updates every 12–24 hours; ARA syncs weekly/monthly for COGS.
What to Do About It
- Compare Apples-to-Apples: Use AMS for ad performance and ARA for inventory/financials.
- Audit with Amazon Attribution: For brands running off-Amazon ads, use Attribution reports to bridge gaps.
- Expect Variance: A 5–15% discrepancy is typical due to attribution rules.
Business & Sales Report – Best Practices
Data Timing & Update Frequencies
Common Discrepancies & Fixes
Ordered vs. Shipped Sales:
- Ordered Product Sales: Captured at purchase (includes pending/cancelled).
- Shipped Product Sales: Updated after shipment (excludes cancellations).
- → Always check which metric your report uses.
Amazon’s Reporting Bugs:
- Expect 1–2 data outages per year (vs. 1–2 months previously). Recent issues include delayed Sponsored Brands sales (2023) and misplaced attribution in Q4.
- Workaround: Cross-check with Amazon Retail Analytics (ARA) for Vendor Central users.
💡 Pro Tips:
- For Real-Time Decisions: Use the Sales Dashboard but spot-check against Business Reports after 48 hours.
- For Month-End Close: Wait until the 5th–7th of the month to ensure all trickle-in sales (e.g., late shipments, returns) are recorded.
- For Audits: Download both Ordered and Shipped Sales reports to identify cancellation trends.
Conclusion
Mastering Amazon Advertising Reports is essential for brands seeking to drive efficient ad spend and maximize ROI across their campaigns. While each report offers unique insights, understanding their limitations and discrepancies is just as critical as interpreting the data itself.
Brands must learn to balance real-time dashboards with historical reports, and audit third-party tools carefully to ensure strategic decisions are grounded in reliable data.
By proactively identifying inconsistencies and aligning reporting windows, advertisers can avoid costly missteps and build smarter, more resilient advertising strategies on Amazon.
