Best Amazon account and PPC audit services in 2026

The best Amazon PPC audit service for established brands is one that delivers ASIN-level findings, reports TACoS alongside ACoS, and ranks every fix by revenue impact; Olifant Digital is our pick overall, and the other 7 cover narrower audit scopes. Olifant Digital manages $100M+ in annual Amazon client revenue across 50+ Amazon accounts, with 98% client retention. This guide ranks 8 audit services, shows how to choose between them, explains what a PPC audit checks, and lists the red flags to watch for.

TL;DR

Top 8 Amazon account and PPC audit services in 2026

1. Olifant Digital: best overall for in-depth account audits for established brands

27% revenue growth in 30 days. Beauty by Earth, an 8-figure clean beauty brand with over 100 ASINs, after the audit rebuilt campaigns by ASIN, match type and targeting. Five new products launched off that foundation.

Free audit | 60-day guarantee: if we don't improve your performance, you don't pay | 98% client retention | Senior-only team

Olifant Digital is a full-service Amazon and e-commerce marketing agency for established brands that want profitable growth, managing $100M+ in annual Amazon client revenue across 50+ Amazon accounts. Its audits cover Amazon PPC, listings and SEO, catalog health and account health, and the same senior team runs ongoing Amazon account management, PPC and DSP, plus Walmart and Target.

Most agencies use the free audit to get a foot in the door. A report arrives, it says something vague about your ACoS trending high and your listings having room for improvement, and then the pitch begins. You leave the call knowing roughly what you already knew going in.

Olifant Digital's Amazon account audit is free and runs exactly like the work done on paying clients, because it is the same work.

ASIN-level findings with actual figures attached. TACoS tracked across the full catalog so you can see what ad spend is really doing to total revenue, including the organic sales Amazon never attributes to clicks. Conversion rates measured against what the category is actually averaging, with the gap translated into what it is costing you. Backend keyword fields checked one by one. Nothing is held back just because you have not signed anything yet.

Beauty by Earth came in as an 8-figure clean beauty brand with over 100 ASINs and a founder managing PPC without any real structure underneath it. The audit found the gaps. Campaigns were rebuilt by ASIN, match type, and targeting strategy, and for the first time the team had full TACoS visibility across every product in the catalog. Revenue grew 27% in 30 days and five new products launched off the back of that foundation.

"Olifant Digital is the best agency I have ever worked with."

Prudence Millsap, Co-Founder at Beauty by Earth

171% revenue growth in two months. Balanced Tiger, after broad keywords that had never converted were cut and campaigns rebuilt on the 1-1-1-1 structure. ACoS came down 50% over the same period.

Balanced Tiger is the other side of the same story. Previous agencies had been running broad, competitive keywords that looked busy but had never actually converted. The audit found exactly where the money was going, cut what was not working, and rebuilt campaigns using the 1-1-1-1 structure. Revenue grew 171% and ACoS came down 50% in two months.

"Extremely effective. Excellent communication and project management to implement widespread changes over a short period."

Adriano Bordoli, CEO at Balanced Tiger

What they're known for

• ASIN-level PPC findings with actual spend figures that show exactly where the real problems are sitting
• TACoS tracked across the full catalog so the relationship between ad spend and total revenue is measured directly
• Conversion rates benchmarked against the category average with the gap quantified in revenue terms
• Olifant Digital's analysis of 50+ managed accounts shows 91% average year-on-year revenue growth and an 84% average conversion rate increase

Best for: Brands that want to know exactly what is wrong with their account before deciding what to do about it.

Pricing: The audit is free as part of the free marketing plan. Our management services start from $2,000 per month and are custom for each project, based on the complexity and workload required. No juniors, no templates.

Limitation: Olifant caps intake to protect the senior-only model, so if timing is tight, it is worth reaching out sooner rather than later.

2. Sitruna: ex-Amazon Seller Central team

Brands that keep hitting the same wall with Seller Support, suppressed listings, or catalog errors need an audit team that has sat on the other side of the platform. Sitruna is built around exactly that: a majority ex-Amazonian team, including operations specialists who came directly from Amazon Seller Support.

Their audit process runs through a proprietary Profitability Dashboard that surfaces net-profit visibility Seller Central does not show natively, which changes what an audit actually catches versus a standard review of ad metrics alone.

What they're known for

• Majority ex-Amazon team including former Seller Support staff, with direct experience inside the platform
• Proprietary Profitability Dashboard surfacing net-profit data not visible in Seller Central
• No Seller Central access required to run the initial audit

Proven results: Verified Clutch review from a pet supplements brand reports increased revenue and sales following Sitruna's Seller Central troubleshooting and PPC optimization work.

Typical client: Brands dealing with recurring Seller Central operational issues (suppressed listings, catalog errors, account health problems) who want an audit run by people who worked inside Amazon.

Pricing: Contact for pricing.

Limitation: Sitruna's documented strength is Seller Central operational depth; their Vendor Central-specific audit experience is less publicly documented than their Seller Central work. Confirm Vendor Central scope directly if that is a requirement.

3. Trivium Group: full account review

Trivium Group was founded by Mina Elias. Its audit reviews PPC, listings, catalog health, and wasted spend together, for brands whose concerns go beyond advertising.

What they're known for

• Full-account health review covering PPC, listings, and catalog health under one audit
• Founder-led agency

Proven results: Named clients include Labrada, Neuro Gum, FitTea, HappyV, and Real Mushrooms, with results reported as portfolio-level averages.

Typical client: Brands that suspect the problems go beyond PPC.

Pricing: Contact for pricing.

Limitation: Case studies are reported as portfolio-level averages, with no individual client breakdown. Ask for the specific breakdown for your category before signing.

4. Elev8 Brands: audit within an integrated strategy

Elev8 Brands was built by former Amazon sellers who understand Seller Central from the operator side, and their audit is delivered as one part of an integrated PPC, SEO, listings, and A+ content strategy.

What they're known for

• Audit delivered as part of an integrated PPC, SEO, listings, and A+ content strategy
• Founder-led team built by former Amazon sellers

Proven results: A Trustpilot review from a CPG client reports sales growth after onboarding.

Typical client: Brands that want an audit before deciding what comes next.

Pricing: Contact for pricing.

Limitation: Elev8's selective roster model means availability may be limited, and verified case studies are currently limited in number. Ask for category-specific references before signing.

5. Nuanced Media: consumer brand audits

Nuanced Media's audit approach reflects their broader philosophy: transparency first, no vanity metrics, and a clear answer to what is driving performance and what is not. For consumer brands where the full customer journey matters, their audit maps paid and organic performance together against that journey.

What they're known for:

• TACoS-tracked audit with profitability measured at every funnel stage
• Full-funnel analytics surfaced during the audit so findings are grounded in actual buyer behavior

Proven results: No verified named client results available.

Typical client: Consumer and lifestyle brands that want an audit built around profitability and full-funnel visibility.

Pricing: Contact for pricing.

Limitation: Specific audit deliverables and turnaround are not publicly available. Verify scope directly before engaging.

6. Amazon Brand Doctor: Brand Registry and compliance audits

Some account problems are Brand Registry problems. Unauthorized sellers altering your listings, compliance gaps blocking A+ content, IP enforcement tools left unused. Amazon Brand Doctor specializes in this layer of the account and audits it specifically.

What they're known for:

• Brand Registry audit covering IP protection setup, Transparency enrollment, and enforcement workflow gaps
• Compliance review identifying listing suppression issues, counterfeit exposure, and unauthorized seller activity
• Focused scope on brand protection

Proven results: Specific named client results are not publicly available. Verify directly before engaging.

Typical client: Brands actively losing Buy Box or listing control to unauthorized sellers and counterfeit activity.

Pricing: Contact for pricing.

Limitation: Scope is narrow by design. If PPC or listing CVR are your primary audit needs, this is not the right starting point.

7. Marketplace Valet: FBA operational audits

Marketplace Valet starts every engagement with what they call "found money." Amazon loses inventory, overcharges on FBA fees, and fails to process returns correctly. Their reimbursement audit covers 18 months of data. That is before a single PPC bid is touched.

Amazon updated its manual FBA claim windows in fall 2024. Under that update, claims for items lost or damaged inside its fulfillment centers must be filed within about 60 days, a guideline Amazon's Seller Forums team reiterated in 2026. Since November 1, 2024, Amazon also reimburses items lost in its fulfillment centers automatically, so check your Reimbursements report first and ask how much of an 18-month lookback is still claimable.

What they're known for:

• FBA reimbursement audit covering lost inventory, damaged items, inbound discrepancies, and overcharged fees
• 3P360 client dashboard giving full visibility over inventory health, ad performance, and fulfillment compliance in one place
• Operational audit extended to supply chain and FBA prep compliance, reducing downstream account health issues

Proven results: Specific named client revenue metrics are not publicly available. Contact for case studies.

Typical client: Mid-seven-figure FBA brands losing margin to operational inefficiency.

Pricing: Contact for pricing.

Limitation: Primary strength is operational and FBA. PPC and listing CVR audit depth should be verified directly before engaging.

8. Emplicit: attribution-based audit reporting

Emplicit prices by time spent on the account, so there is no incentive to deliver quickly and move on. The audit is the first step of an engagement.

What they're known for:

• Attribution analysis connecting ad spend, organic performance, and profitability at the account level
• TACoS and CVR both tracked and benchmarked, with findings structured around revenue impact
• Time-based pricing with no incentive to rush findings or skip the iteration phase

Proven results: Paleovalley: 50% year-over-year revenue growth to eight figures.

Typical client: Established brands with meaningful Amazon revenue that want audit findings structured by revenue impact and backed by full attribution analysis.

Pricing: Time-based retainer. Contact for details.

Limitation: Built for brands already generating significant Amazon revenue. Early-stage sellers may find the model less suited to their current scale.

Free vs paid Amazon audits: What is the actual difference?

What most audits hand over

• A branded PDF with traffic-light scoring
• ACoS above benchmark, listings have room for improvement
• A closing slide on the services the agency sells

What a real audit finds

• The exact keywords burning budget without a conversion
• Which ASINs are suppressed, and what is causing it
• A fix order set by what each problem is costing you

According to Marketplace Pulse, 46% of Amazon-active sellers surveyed cited advertising spend as a margin concern, so an audit must show where that spend goes.

Honestly, the price has very little to do with it.

That might sound like a strange thing to say in a section literally titled free vs paid, but it is the truth.

What comes out of an audit matters more than what it costs. And that distinction gets lost the moment someone slaps the word "free" on something and calls it a diagnostic.

Most free audits follow the same pattern. A branded PDF arrives, tells you your ACoS is above benchmark and your listings have room for improvement.

There might even be a traffic light somewhere. Green, amber, red. Very official looking. And then comes the slide that explains which services the agency offers and why now is a great time to get started.

You close the PDF knowing roughly what you already knew before you opened it. (Sounds familiar?)

A real audit tells you things you did not know. This includes which specific keywords are burning through your budget without a single conversion. Also, which ASINs are suppressed and what is causing that to happen. These things matter and this is what a real audit will show you.

Olifant Digital's free audit works exactly that way. Same depth, same ASIN-level findings as the work done on paying clients, because it is genuinely the same process.

So before you request one from anyone on this list, ask to see an example output first. What comes back, and how quickly it comes back, will tell you more about that agency than anything else on their website.

What does an Amazon PPC audit service check?

A PPC audit covers the advertising layer of the account, campaign by campaign and ASIN by ASIN. Our Amazon PPC management service starts with a PPC audit of these five areas. To check an agency that already runs your ads, use our guide to auditing your Amazon PPC agency.

1. Check campaign architecture against four focuses: testing, scaling high performers, exact match campaigns for organic rank, and brand defense.
2. Review search term reports for keywords that keep spending without converting, since they drain budget with no sales to show for it.
3. Audit match type and targeting structure against the 1-1-1-1 Scaling Method, our proprietary campaign architecture framework.
4. Compare ACoS with break-even ACoS, your profit margin before ad costs, because every point above it loses money on ad sales.
5. Track TACoS by ASIN to see which products depend on ads for their revenue.

Run the full PPC audit every 6 months while the account is scaling, at least once a year otherwise, and watch TACoS by ASIN between audits.

How to choose the right Amazon account or PPC audit service

1. Ask exactly what the audit covers and what you receive
2. Check whether findings are prioritized by revenue impact
3. Confirm the audit works at ASIN level
4. Confirm TACoS is reported alongside ACoS
5. Ask for a prioritized action plan

1. Ask what the audit specifically covers and what you receive

This sounds obvious until you actually ask it and get a vague answer back. "We review your full Amazon account" means nothing without specifics.

What you want to hear is PPC campaign structure by ad type, TACoS trend over a defined period, listing CVR benchmarked against category, and suppressed ASINs identified individually. Just as importantly, ask what the deliverable actually looks like.

2. Find out whether findings are prioritized by revenue impact

Getting a list of thirty things that could be improved sounds helpful until you are staring at it wondering where to begin. The agencies doing this properly rank every observation by what it is costing you and tell you which to fix first.

Without that order, most brands work through the easiest items first and leave the most valuable ones for later, which is a very efficient way of making very little actual progress.

3. Check that they audit at ASIN level

Account level metrics are summaries, and summaries hide things. A TACoS reading of 15% across the account can look perfectly manageable while one ASIN is sitting at 40% and quietly pulling everything down around it.

If the agency cannot break findings down by ASIN, what you are getting is a dashboard overview with a professional cover page on it.

4. Confirm they report TACoS alongside ACoS

ACoS will tell you how efficiently your ads are converting clicks into sales and while that sounds useful, it isn't when you realize that it only measures the revenue your ads directly touch. TACoS, on the other hand, measures what your total ad spend is doing to your overall revenue, and this also includes organic sales.

According to Amazon Ads, ACoS is calculated by dividing ad spend by ad revenue and converting it to a percentage.

TACoS divides the same ad spend by total revenue.

• ACoS = ad spend ÷ ad revenue × 100
• TACoS = ad spend ÷ total revenue × 100

Plug $1,500 of spend, $6,000 of ad revenue, and $15,000 of total revenue into our free Amazon TACoS calculator: ACoS is 25%, TACoS is 10%.

5. Ask for a prioritized action plan

The report should always include what's next in terms of what needs fixing, in what order, and what each fix is realistically expected to produce. So if they can't produce an action plan, then what's the point?

Red flags to watch for when requesting an Amazon account audit

• The audit is delivered verbally on a call with no written document provided
• Findings are presented at account level only with no ASIN-specific data anywhere in the report
• The report includes ACoS with no TACoS data
• Recommendations stay generic ("improve your listings") where they should be specific ("ASIN B00XXXXX has 8.4% CVR vs 14.2% category benchmark, main image and A+ content are the primary gap")
• The agency cannot explain which data sources they pulled from or how the findings were calculated
• Conversion gets a general observation that it could be better, with no CVR benchmarking against category averages
• Every finding in the report happens to lead to a service the agency sells
• Findings arrive as a flat list of observations with no priority order and no indication of what to fix first
• The audit is completed within 24 hours for a complex multi-ASIN account
• No example output available before you commit to the process

Which type of Amazon account audit is right for you?

Best for brands with complex, high-SKU accounts

If you are managing a catalog of 50 or more ASINs and things have gotten structurally messy over time, Olifant Digital is the right starting point.

The Beauty by Earth case study exists precisely for this situation. Over 100 ASINs, no clear campaign structure, a founder managing PPC without the visibility needed to make good decisions.

The audit found the specific problems, built a clear rebuild plan around them, and Beauty by Earth grew revenue 27% in 30 days.

Best for brands with rising ACoS and flat revenue

This is the situation where the numbers are technically moving but nothing feels like it is actually working.

Olifant Digital and Emplicit take different routes here. Olifant Digital identifies the exact keywords and ASINs driving the waste and rebuilds from there, as the Balanced Tiger case study shows clearly.

Emplicit approaches it through attribution analysis, connecting ad spend to organic performance to total profitability. Two different routes to the same destination.

Best for brands with catalog and listing issues

Elev8 Brands covers listings, A+ content, and PPC together in one integrated pass.

For brands that want listing work connected to broader account performance, Olifant Digital handles keyword research, listing copy, backend indexing, and flat file management as ongoing parts of full account management.

Best for brands evaluating a new agency

Start with Olifant Digital's free audit before committing to anyone. The findings give you a clear baseline of what is actually wrong with your account, which makes every subsequent agency conversation more specific and a lot harder to sidestep with broad promises.

It is genuinely free, with no sales pitch attached, and that matters more than it probably should in this industry.

Frequently asked questions

What does an Amazon account audit actually include?

A proper audit covers PPC campaign structure, TACoS and ACoS trends, listing conversion rates benchmarked against category averages, suppressed and stranded listings, backend keyword indexing, catalog health, and account health metrics. Anything shallower is a summary. For the listing side, see our Amazon SEO audit guide, listing optimization guide and backend keywords guide.

How is an account audit different from a PPC audit?

A PPC audit looks specifically at your advertising campaigns, bid structure, keyword targeting, and ad spend efficiency. An account audit is broader. It looks at everything that affects performance, including listings, catalog structure, Brand Registry, inventory health, and organic rankings alongside the advertising layer.

How long does an Amazon account audit take?

For a straightforward account, a thorough audit typically takes a few days. For complex accounts with large catalogs, expect longer. Any agency completing a detailed audit on a 100-plus ASIN account within 24 hours is not going deep enough.

What happens after an audit? Do I need to hire the agency that did it?

No. The findings belong to you and you are under no obligation to work with the agency that produced them. A good audit gives you enough information to act on independently or take to any agency you choose.

How do I know if an audit finding is worth acting on?

An audit finding is worth acting on when it names a specific keyword, ASIN, revenue gap, or conversion rate. If it is a general observation without data behind it, treat it accordingly.

How often should an Amazon account be audited?

At minimum once a year, but realistically every six months for accounts that are actively scaling. Amazon changes frequently and what was working structurally six months ago may not be the most efficient setup today.

How much does an Amazon PPC audit service cost?

Olifant Digital's audit is free as part of the free marketing plan, and our management services start from $2,000 per month and are custom for each project, based on the complexity and workload required. The other 7 agencies listed here price on request, and Emplicit uses a time-based retainer.

How do I get started with an Amazon account or PPC audit?

Start by asking the agency for an example audit output before you commit. Confirm whether the scope covers Seller Central, Vendor Central, or both. Then ask whether the agency needs Seller Central access, since Sitruna runs its initial audit without it. For Olifant Digital, start with the free marketing plan.

Key takeaways

• Account averages hide problem ASINs. A 15% TACoS across the account can mask a single ASIN running at 40%.
• Depth takes more than a day. Any agency returning a detailed audit of 100+ ASINs within 24 hours has skipped the work.
• Twice a year while scaling. Scaling accounts need a full audit every 6 months, and every account needs one yearly at minimum.
• Old FBA losses expire fast. Amazon's guidance, set in fall 2024 and reiterated by Amazon staff in 2026, is that manual claims for items lost or damaged in its fulfillment centers be filed within about 60 days.
• Growth across the account base. Revenue grew 91% year on year on average, according to Olifant Digital's analysis of 50+ managed accounts.

Final thoughts

An audit is only valuable if it surfaces problems specific enough to act on. It earns its fee with an ASIN-level diagnosis, findings ranked by revenue impact, and a clear plan for what to fix first.

Most of the audits offered in the market right now are sales tools with the word "audit" on the cover.

Olifant Digital's free audit is the exception. Same methodology, same diagnostic depth, same output as a paid client engagement. If your account has structural problems you have not been able to locate, this is where to start.
