Understanding Metric Discrepancies Between Different Reports

July 21, 2026 22:33

Why the numbers sometimes look different across report types — and when that's expected.

This article is a quick reference for interpreting Campaign, Ad Group, Targeting, Search Term, Ads, Advertised Product, and Placement reports, and knowing when a difference between them is normal rather than a sign of a data problem.

The short answer

Most Amazon Ads reports are simply the same data shown at a different level of detail. Think of your Campaign total as the whole pie. Ad Group, Targeting, and Search Term reports are just that same pie sliced into smaller and smaller pieces — add the slices back together and you get the whole pie back. These should always match.

Ads, Advertised Product, and Placement reports are a little different. They're useful, accurate views — but for specific, well-understood reasons, they don't always add back up to the exact campaign total. That's expected, not an error.

Quick Reference: How Each Report Compares to Campaign Totals

Report Type	Vs. Campaign Totals	What to Know
Ad Group	Should match	Ad Groups are simply the campaign divided into smaller pieces. Add up every ad group in a campaign and you get the campaign total, every time.
Targeting	Should match	Targeting breaks each ad group down further, into the individual keywords or products you're targeting. Add up all the targeting rows in a campaign and it equals the campaign total.
Search Term	Should match	This shows the exact words a customer typed before your ad showed up. Every search term rolls up into the keyword it matched, which rolls up into the campaign — so this also reconciles.
Ads	Expected to differ	Usually reconciles closely, but two things can create a small gap: a paused/deleted ad still counts toward the campaign's history but may no longer show up in this report, and editing an ad's creative can start a fresh performance history for it.
Advertised Product	Expected to differ	Works well for Sponsored Products and Sponsored Display, where each ad promotes one product. For Sponsored Brands, a single ad can feature several products at once, so there's no product-by-product breakdown for that ad type.
Placement	Expected to differ	Shows where your ad appeared. It's a different way of slicing the same campaign data, not a smaller piece that adds back up to it — see below for why.

Why Placement, Ads, and Advertised Product can look different

Use the tabs below to see the specific reason for each report type.

Placement shows where an ad appeared — for example, at the top of search results versus on a product page. Some traffic and some sales can't be neatly credited to just one placement, especially if a customer saw the ad in more than one spot before deciding to buy.

Because of this, Placement totals will often come in a bit lower than the full Campaign total. Use Placement data to compare performance between locations, not as a number that should reconcile exactly.

This usually lines up well with Ad Group and Campaign totals. Small gaps happen when:

An ad has been paused or removed — its past performance still counts toward the campaign, but it may no longer appear in this report.
An ad's creative was recently edited, which can make its performance history look like it restarted.

For Sponsored Products and Sponsored Display, this report shows performance for the exact product being advertised, and it lines up well with the Ads report.

For Sponsored Brands, a single ad can promote multiple products together, so Amazon doesn't provide a product-by-product breakdown for that ad type — the spend and sales are still counted at the campaign level, just not split out this way.

Good to know

None of the differences above reflect missing or inaccurate data. They're a result of how Amazon's attribution model works — campaign-level totals should always be treated as the source of truth.

What Report Type Powers Pacvue Pages

Different pages in the Pacvue platform uses different report types as the data source. The source of data for My Reports is dependent on the selected report (i.e. Campaign My Report is sourced from Campaign Report Type). Likewise for the Custom Dashboard, the source of data is dependent on the selected material level for a dashboard module. Below are the data levels and which page in Pacvue they are the source of data for.

Data Level	Pacvue Pages
Report Type - Campaign	Advertising Campaign, Ads Home Dashboard
Report Type - Placement	Advertising Placement
Report Type - Ad Group	Advertising Ad Group
Report Type - Ads	Advertising Ads
Report Type - Targeting	Advertising Targeting
Report Type - ASIN	Advertising ASIN, Commerce Home Dashboard, Commerce Sales, Product Dashboard, Product Listing
Report Type - Search Term	Advertising Search Term

When looking into data discrepancy for a specific page in Pacvue, reference the data level that powers the particular page.

Troubleshoot Data Discrepancies

If you ever see a difference here, it's possible it may be one of these two things, rather than a data problem:

Different date ranges or filters were used when pulling the two reports. Make sure to clear filters or ensure that identical filters are applied.
The report was pulled too soon — sales data can take a few weeks to fully settle as orders complete, so a very recent pull may look smaller than the same report pulled again later.

Data Discrepancies Due to Intra-Day Reporting Sync

When a date range includes intra day data the source of a data discrepancy may be due to the frequency at which different reports are pulled throughout the day. Intra day campaign reports are synced every 3 hours while all other reports are pulled once a day. When comparing data between two report types, then it is best to not include intra day date range when making the comparison.

Frequently asked questions

Which number should I trust?

Campaign-level totals are always the most complete and reliable number. Ad Group, Targeting, and Search Term data will match it exactly. Ads, Advertised Product, and Placement are useful for understanding where performance is coming from, but treat any small gap against the campaign total as expected, not a red flag.

Why did an ad's numbers suddenly change even though I didn't touch the campaign?

This is almost always the result of an ad edit (like a new image) creating a fresh version of that ad behind the scenes, or an ad being paused/removed. The campaign total itself is unaffected.

Why don't my Placement numbers add up to my Campaign number?

This is expected. Placement is a different lens on the same data, and not every sale can be pinned to a single location, especially when a customer's path to purchase touched more than one placement.

Why can't I see product-level performance for my Sponsored Brands campaign?

Sponsored Brands ads can showcase several products in one ad, so Amazon doesn't offer a product-level breakdown for that ad type the way it does for Sponsored Products and Sponsored Display.

Bottom line

If a report is a smaller slice of the same pie (Ad Group, Targeting, Search Term), it should match the Campaign total exactly. If it's a different lens on the same data (Placement, Ads, Advertised Product), expect it to come in a little lower — and that's by design, not a data issue.
