Introduction
Key Takeaways
● If an agency sends you a free audit and you cannot find a single ASIN or dollar figure anywhere in it, what you got was a pitch with a cover page. That is the most important thing to understand before you request one from anyone on this list.
● Most of the problems sitting in an Amazon account are not complicated or hidden. Spent going to keywords that have never been converted, listings suppressed for weeks with nobody noticing, TACoS quietly rising while ACoS looks fine on the surface. They show up the moment someone looks carefully enough. The problem is that most audits never get that far.
● Olifant Digital's free audit runs exactly the same way as the work done on active clients. ASIN-level findings, TACoS tracked across the full catalog, conversion rates measured against what the category is actually averaging. The fact that you have not signed anything yet does not change what goes into it.
● Not every audit is going after the same problem. A brand bleeding money on broad match keywords needs something very different from a brand losing listings to unauthorised sellers. Getting clear on which situation you are actually in before approaching any agency will save you real time and real money.
● An audit without a priority order is just a list. The good ones tell you what is costing you the most, what to fix first, and why that sequence matters. Without that, you are left guessing where to start.
Most Amazon brands are losing revenue in places they have stopped looking. Spend going to keywords that have never once converted. Listings suppressed for weeks while the account dashboard looks perfectly fine. TACoS creeping up month after month while ACoS stays flat and gives everyone a false sense of confidence.
And the frustrating part is that none of this is hard to find once someone actually goes looking. (It just turns out that most audits never do.)
Without a proper one, you end up optimising what is visible and missing what is quietly doing the damage. This article ranks the best Amazon account audit services by the quality of what they actually find. Olifant Digital ranks first for 2026.
Top 8 Best Amazon Account Audit Services in 2026
1. Olifant Digital — Best Overall for In-Depth Account Audits for Established Brands
Free Audit | 60-Day Money-Back Guarantee | 98% Client Retention | Senior-Only Team
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 does not do it that way. The free audit 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, not just the part Amazon 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
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, not account-level summaries that smooth over where the real problems are sitting
● TACoS tracked across the full catalog so the relationship between ad spend and total revenue is visible, not estimated
● Conversion rates benchmarked against the category average with the gap quantified in revenue terms, not just noted as an observation
Best For: Brands that want to know exactly what is wrong with their account before deciding what to do about it.
Pricing: Free as part of onboarding. 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. SalesDuo — Best for Seller Central and Vendor Central Audits
Brands selling across both Seller Central and Vendor Central already know how differently the two operate. Most agencies know one well but try to figure out the other as they go, and that gap shows up in the audit before it shows up anywhere else. SalesDuo earns the second spot on this list because they are one of the very few where that is genuinely not the case.
85% of the team are former Amazon employees, the founder included. People who spent years inside the platform before ever working on it from the other side. That kind of context is hard to manufacture and even harder to replace. (There is a reason brands with complex hybrid accounts keep coming back.)
Their proprietary BI dashboard pulls ad attribution, inventory health, and category performance into one view during the audit process. Which sounds like a feature until you realise most audits are reviewing campaigns completely in isolation and hoping the rest of the picture connects on its own. It rarely does.
What They're Known For
● Genuine depth across both Seller Central and Vendor Central, not comfort in one and a working knowledge of the other
● BI dashboard connecting attribution, inventory, and category performance so the audit is never working with half the information
● AI-powered monitoring surfacing account anomalies a standard review would walk straight past
Proven Results: TNG Worldwide: 570% sales increase within one year, 286% growth in brand awareness.
Best For: Brands operating across both platforms who need an audit that genuinely understands the structural differences between the two.
Pricing: Contact for pricing.
Limitation: Audit format and turnaround are not publicly detailed. Ask for the full scope before committing.
3. Canopy Management — Best for Full Account Health Review
You know that feeling when you are pretty sure something is wrong but every number you look at seems fine? You've got the sales coming in, the campaigns are running, and nothing seems broken, but that feeling that something seems off is left unidentified. Well, that's when you know a proper account health review is needed.
And when that point comes, Canopy Management is the engagement most brands look for.
With over 1,000 brands under management and $3.3 billion in partner revenue, they have simply seen it all before. (Every account tells a version of the same story once you have looked at enough of them, and Canopy has looked at a lot.)
The account review Canopy does covers ads, listings, SEO, wasted spend, and growth opportunities together instead of treating each as a separate problem that requires a separate solution.
What They're Known For
● Broad account health review covering PPC, listings, catalog gaps, and wasted spend without treating each as a separate conversation
● Proprietary AdVantage software which can catch campaign inefficiencies that tend to get overlooked in a manual pass
● Benchmarking context drawn from managing accounts at scale across dozens of categories
Proven Results: MaryRuth Organics: 430% increase in sales with ACoS down 30% over 18 months.
Best For: Brands that suspect the problems go beyond PPC and want a review that looks at the whole account rather than one corner of it.
Pricing: Contact for pricing.
Limitation: Some verified reviews have flagged account manager rotation, so when you do connect with them, it is worth asking upfront who's going to run the audit and whether that same person stays on it throughout.
4. My Amazon Guy — Best for Budget-Accessible Audits
If the budget is not there yet for a full agency engagement but you still need a proper look at what is going on inside the account, My Amazon Guy is the most structured option at this price point. And structured is the right word for it.
Their 75-point audit covers PPC campaigns, organic rankings, account health, IPI scores, Brand Registry compliance, and catalog structure, all in one written report. The part that actually matters though? You get a clear picture of what to fix first, not just a list of everything that could theoretically be better. (Most audits stop at the list. This one does not.)
Founder Steven Pope has also published the thinking behind the whole process openly on YouTube, so you can see exactly how they approach an account before spending anything at all.
What They're Known For
● 75-point written audit covering PPC, SEO, account health, catalog structure, and Brand Registry in one pass
● Transparent process with publicly available SOPs so you know what is being reviewed and why
● Accessible entry point with no long term commitment required upfront
Proven Results: K'lani: 1,218% increase in sales with 56.6% reduction in ad cost across a full account rebuild.
Best For: Brands who need a thorough written audit at an accessible price point before deciding what comes next.
Pricing: Contact for pricing.
Limitation: With 500-plus team members, the person running your audit matters. Ask who specifically will be doing the work before agreeing to anything.
5. Nuanced Media — Best for Consumer Brand Account 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 both paid and organic performance against that journey rather than reviewing each in isolation.
What They're Known For:
● TACoS-tracked audit with profitability at every funnel stage, not just ad-level ACoS
● Full-funnel analytics surfaced during the audit so findings are grounded in actual buyer behaviour
● Named clients including Dollar Shave Club and True Citrus in top-10 category positions
Proven Results: No verified named client results available.
Best For: Consumer and lifestyle brands that want an audit built around profitability and full-funnel visibility, not just campaign performance.
Pricing: Contact for pricing.
Limitation: Specific audit deliverables and turnaround are not publicly available. Verify scope directly before engaging.
6. Amazon Brand Doctor — Best for Brand Registry and Compliance Audits
Some account problems are not PPC problems or listing problems. They are Brand Registry problems. Unauthorised sellers altering your listings, compliance gaps blocking A+ content, IP enforcement tools left unused. Amazon Brand Doctor specialises 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 unauthorised seller activity
● Focused scope on brand protection rather than broad account management
Proven Results: Specific named client results are not publicly available. Verify directly before engaging.
Best For: Brands actively losing Buy Box or listing control to unauthorised 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 — Best for 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 and routinely recovers between $10,000 and $50,000 for mid-seven-figure brands. That is before a single PPC bid is touched.
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.
Best For: Mid-seven-figure FBA brands losing margin to operational inefficiency rather than advertising underperformance.
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 — Best for Data-Driven Audit Reporting
Emplicit prices by time, not by project. That single structural choice changes everything about how they approach an audit. There is no incentive to deliver quickly and move on. Their model rewards finding the actual problem, not the visible one. On average, their clients recover between $120,000 and $240,000 in missed revenue after an engagement, and the audit is where that process starts.
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 not just metric performance
● 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.
Best For: 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?
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.
The most important thing about an audit is not what it costs. It is what comes out of it. 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.
How to Choose the Right Amazon Account Audit Service
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 Prioritised 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 do not just hand you observations, they tell you which ones are costing you the most and which to fix first.
Without that order, most brands end up working through the easiest items rather than the most valuable ones, which is a very efficient way of making very little actual progress.
3. Check if They Audit at ASIN Level and Not Just Account 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 tell you how findings break down by ASIN rather than at campaign or account level, what you are getting is a dashboard overview with a professional cover page on it.
4. Confirm They Report on TACoS and Not Only ACoS
ACoS will tell you how efficiently your ads are converting clicks into sales and while that sounds useful, it isn't when you realise 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.
5. Ask Whether the Audit Comes With an Action Plan or Just a Report
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
● No TACoS data included, only ACoS
● Recommendations are generic rather than specific ("improve your listings" instead of "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
● No CVR benchmarking against category averages, just a general observation that conversion could be better
● Every finding in the report happens to lead to a service the agency sells
● No priority order in the findings, just a flat list of observations with 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 delivered measurable results within 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 or Emplicit are both strong here for different reasons. 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
My Amazon Guy is the most practical option here. The 75-point audit covers listing structure, Brand Registry, catalog health, and account flags in one pass, and the price point makes it accessible for brands that are not yet ready for a full agency engagement.
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 part of full account management rather than as a one-off fix.
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, not a free consultation with a pitch at the end, and that distinction matters more than it probably should in this industry.
Final Thoughts
An audit is only valuable if it surfaces problems specific enough to act on. Not a high-level health check with traffic lights and broad observations, but an ASIN-level diagnosis with findings ranked by revenue impact and a clear plan for what to fix first.
Most of the audits being offered in the market right now are not that. They 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.

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. If it does not go that deep, it is a summary, not an audit.
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?
If the finding comes with a specific figure attached, a keyword, an ASIN, a revenue gap, a conversion rate, it is worth taking seriously. 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.
