Amazon PPC Audit: What It Actually Checks (With a Template)

What an Amazon PPC audit actually checks

An Amazon PPC audit is a line-by-line review of an ad account against what actually converts, not what looks efficient in a dashboard. It checks six things: campaign structure, search term waste, keyword harvesting, ad type coverage, budget pacing, and attribution accuracy. Most sellers only ever look at the first number Amazon shows them — ACOS — and never open the search term report underneath it.

• Campaign structure: are branded, category, and competitor keywords split into separate campaigns, or mixed together so you can't tell what's driving the spend?
• Search term waste: which specific search terms inside broad and auto campaigns have burned spend with zero orders in the last 30-60 days?
• Keyword harvesting: of the terms that are converting, how many have been moved into their own exact-match targets where you control the bid, versus still buried in a broad bucket?
• Ad type coverage: is the account running Sponsored Products only, or using Sponsored Brands and Sponsored Display where they'd add reach without cannibalizing the account's own terms?
• Budget pacing: which winning campaigns run out of budget before the day ends, meaning you're capping your best performers, not your worst?
• Attribution accuracy: is a Sponsored Display campaign running on vCPM (view-based) instead of CPC, which can credit an ad with a sale nobody clicked?

A worked example — the math an audit actually runs

Here's how the math runs, using round numbers to show the shape of it — not a real account, just the arithmetic.

Take a campaign spending $8,000 a month across 60 search terms. Sort by orders and you find 14 of them have driven zero sales in 60 days while still absorbing $1,100 of budget. That $1,100 isn't obviously "bad" spend by ACOS — it's spend that never had a chance to convert. Cutting it doesn't lower ACOS by itself; it frees $1,100 to move toward terms that are already converting but capped.

Now look at one of those converting terms: 20% ACOS, sitting inside a broad campaign that hits its daily budget by early afternoon most days. The impression share report will usually show you're only capturing a fraction of the available auction for that term. Raising the budget on a proven 20% ACOS term is a different decision than raising it on an unproven one — but you can only tell the two apart once they're separated.

That's the whole audit in miniature: find the spend with no evidence behind it, find the evidence with no spend behind it, and move budget from one to the other.

The template: what to pull before you start

A usable amazon ppc audit template doesn't need to be complicated. It needs a handful of columns you can fill in from the search term report, the placement report, and campaign manager — no extra software required to start. The table below is that template: what a healthy account looks like in each area, and the specific pattern that signals it isn't.

When the audit turns up bad news

Sometimes the audit finds real waste, and the instinct is to pause everything that isn't converting, today. Don't. Pause the clearest offenders first — zero orders, 60+ days, meaningful spend — and watch total sales for a week before touching the next tier. If TACOS climbs while ACOS improves, you didn't cut waste, you cut a keyword that was quietly supporting organic rank or cross-shopping traffic that never shows up as a direct ad conversion.

If a budget-capped campaign doesn't hold its ACOS once you raise the budget, that's information too: the keyword was capped because demand was thin, not because money was being left on the table. Raise budgets in steps you can attribute to a single change, not all at once.

If the numbers in the audit don't match Seller Central, check the date range and attribution window before concluding the audit is wrong. Reporting lag and window differences explain most of these mismatches.

The mistake we see most (and one we've made ourselves)

The most common mistake is treating ACOS as the only signal. A campaign can show a clean ACOS while total account sales fall, because the ad spend is just capturing purchases that would have happened anyway — branded search, vCPM display impressions, ads sitting on the brand's own product pages. ACOS alone can't tell the difference between a sale the ad caused and a sale the ad merely stood next to.

We've made a version of this mistake too: shipping a change that looked correct on ACOS in the first 48 hours, before TACOS had time to move. It's why every proposed change we run now carries three things before it goes live: the evidence behind it, a measurement plan, and a rollback trigger. The trigger exists specifically because the first read on a change is sometimes the wrong one.

Where Dr. PPC fits

If you want to run this audit yourself, the checklist above gets you most of the way, and free tools that read your account — Helium 10's audit among them — are a reasonable way to surface the search term and listing data. They stop at the read, since they're built not to touch your campaigns. Dr. PPC reads the account the same way, then writes and proposes the changes, with the evidence, measurement plan, and rollback trigger attached, at whatever autonomy level you choose. It's $300 a month plus 3% of ad spend, capped, month-to-month, with the first 30 days free, and Orbit — the analytics suite most of this audit runs on — is included at no extra charge. It's operated by Full Circle, which has managed more than $500M in revenue across 100+ brands.
