Most Amazon marketing agencies report ACoS and call it a strategy. ACoS only measures ad efficiency. It says nothing about whether the account is actually making money. If your agency cannot show you what happens to your margin after Amazon’s fees, your ad spend, and their own fee, you are optimizing the wrong number.

Best For: Amazon brand owners, including Amazon FBA brands, who want one team managing advertising, listings, and brand protection together instead of coordinating three separate vendors. Works for brands doing $10,000 to $500,000+ per month in Amazon revenue, on Seller Central or Vendor Central. Especially relevant for brands that have outgrown DIY PPC and need account-level strategy instead of campaign-by-campaign management.
An Amazon marketing agency is not a PPC vendor with a listing audit attached. Advertising drives traffic. Listings convert that traffic into sales. Brand protection keeps the account healthy enough to sell at all. Manage one of these without the other two and you are paying for clicks that land on a weak listing, writing great copy that nobody sees, or running a strong account that one hijacked listing can take down in a week.
The three layers work as one system, which is what separates an Amazon marketing agency from a general e-commerce marketing agency that treats Amazon as one channel among many. Better listings lower your cost per click, because Amazon’s ad auction rewards relevance and conversion rate alongside bid amount. Better organic rank lowers your dependency on ads, because shoppers find you without a sponsored placement. Better brand protection keeps the account eligible to sell in the first place, which nothing else matters without.
Most agencies that call themselves “full-service” manage one of these layers well and touch the other two lightly. The output of doing this properly is not a lower ACoS. It is a profitable Amazon revenue channel that keeps compounding instead of one that needs constant ad spend just to stand still.
This is what a full-service Amazon marketing firm actually does day to day: a done-for-you service across advertising, listings, and brand protection. We do the work. You approve the strategy and see every change before it goes live. Every engagement starts with a full account audit covering ad spend, listing quality, fee structure, and brand health, before we touch a single campaign or rewrite a single bullet point.
Before: $40,000 a month in ad spend at a 28% ACoS, reported as a win because the number was down from 32% the month before. After: the same budget restructured around contribution margin. ACoS actually rises slightly, to 31%, but TACoS drops from 22% to 15% and monthly profit goes up by roughly $9,200. One version optimizes a number on a slide. The other optimizes the business.
We do not report on ad metrics alone, and we do not stop at revenue. We score every account we manage across three layers before we touch a single campaign.
ACoS, ROAS, CPC, CTR, and conversion rate by campaign. This is the layer most agencies report on exclusively, and it is the easiest to manipulate. Cutting spend on a struggling campaign improves ACoS instantly and tells you nothing about whether the account is healthier.
TACoS, contribution margin, the full fee stack, and cost of goods. This is the layer that tells you whether the business is actually making money. A campaign can have a mediocre ACoS and still be worth running if it is pulling in high-margin, high-repeat customers.
Organic rank movement, Brand Registry health, AI-recommendation visibility, and repeat purchase rate. This is the layer that lowers your dependency on ad spend over time, and it is the layer almost nobody reports on because it takes longer to show results.
Most agencies report Layer 1 and stop. We manage all three, because Layer 1 alone can mislead. Spending less produces the same ACoS improvement as running the account better, and a report that only covers Layer 1 cannot tell the two apart.
A complete account strategy built from the audit up. Not a templated 90-day plan. Not a set of generic best practices. A structured plan built around your actual fee stack, catalog, and margin.
Every engagement includes:
We recommend a full account strategy review every quarter. Monthly campaign tweaks alone do not catch shifts in Amazon’s ad auction or algorithm fast enough.
Before: $40,000 a month in ad spend at a 28% ACoS, reported as a win because the number was down from 32% the month before. After: the same budget restructured around contribution margin. ACoS actually rises slightly, to 31%, but TACoS drops from 22% to 15% and monthly profit goes up by roughly $9,200. One version optimizes a number on a slide. The other optimizes the business.
An account can hit a 15% ACoS and still be losing money. ACoS measures ad spend against ad-attributed sales. It does not touch Amazon’s referral fees, FBA fees, storage costs, returns, or the agency’s own fee. A brand can watch ACoS fall for six months straight while contribution margin quietly goes negative, because nobody on the account is watching the layer underneath the ad report.
Here is where that reporting gap usually starts:
ACoS only measures ad efficiency. TACoS measures ad spend against total sales, including organic. An agency chasing a lower ACoS can cut a campaign that was actually pulling in organic sales alongside the paid ones.
Referral fees, FBA fees, storage fees, and returns come out of every sale before the agency fee is even subtracted. Most monthly reports never show this line.
Revenue growth and profit growth are two different things. An account can grow 40% in sales and lose margin at the same time if the growth came from deeper discounts and heavier ad spend.
Almost every agency in this space routes cost questions to a sales call instead of publishing a real range.
Campaign management with an occasional listing tweak is a narrower job than managing advertising, SEO, creative, and brand protection as one account strategy.
Brands are left to guess what good onboarding, a fair contract, or a legitimate case study actually looks like.
Amazon suspends accounts for incentivized or manipulated reviews. An agency that promises a fixed number of reviews is a bigger risk than the problem it claims to solve.
Amazon's Rufus assistant already handles a meaningful share of product searches through conversational queries instead of keyword strings. An agency still optimizing for A9 alone is managing half the account.
Enrolling takes an afternoon. Actually monitoring for hijackers, counterfeits, and unauthorized sellers is ongoing work that most engagements skip.
Buy Box percentage, inventory health, and organic rank movement say more about account trajectory than click-through rate does, and they rarely make it into the monthly report.
Weekly bid adjustments without a quarterly plan is optimization without a direction.
Every one of these gaps shows up in the first thirty days of a real audit. Most of them do not require new ad spend to fix. They require someone actually looking at the account instead of the dashboard.
Most agencies in this space route every pricing question to a sales call and never publish a number. That makes it hard to know if an offer is fair before you have already spent an hour on a call.
Three pricing models cover most of the market. A flat monthly retainer, usually a fixed range regardless of ad spend. A percentage of ad spend, commonly 10 to 20 percent, which means the agency’s fee rises whenever your ad budget rises, whether or not that spend is profitable. A hybrid model, a lower base retainer plus a performance component tied to revenue or margin growth above an agreed baseline.
Each model carries a different incentive. A pure percentage-of-spend fee rewards an agency for recommending more spend. A flat retainer removes that incentive but does not reward efficiency either. We scope every engagement after the account audit, based on catalog size, current ad spend, and scope of work, and we will tell you which model fits your account and why before you sign anything.
Amazon’s Rufus assistant already handles a meaningful share of product searches through conversational queries, and Amazon is extending that same AI layer across Alexa, Kindle, and Prime Video. A shopper who asks “what’s the best posture corrector for a desk job” is speaking in plain language, not typing a search string. Amazon’s COSMO knowledge graph decides which products it even considers for the answer, based on how completely a listing’s data is structured rather than how well it ranks in traditional search.
An agency that only manages Sponsored Products and title keywords is optimizing for half the discovery system. The other half runs on backend attributes, Q&A depth, and review sentiment, the same signals our Amazon Rufus Optimization service is built around. Brands that get both systems working together now will be harder to displace as AI shopping becomes a larger share of Amazon’s total search volume. Most agencies have not built this into their standard service yet. That gap will not stay open for long.
An Amazon marketing agency manages advertising, listing optimization, and brand protection as one account strategy rather than three separate services. That includes Sponsored Products and Sponsored Brands campaigns, keyword research and copywriting, A+ Content, and monitoring for account health issues like suppressed listings or unauthorized sellers.
A PPC-only agency manages campaigns and reports on ACoS. A full-service agency also manages the listing the ads point to and the account health that keeps the listing eligible to sell, and it reports on contribution margin as well as ad efficiency. Both matter, but only one of them tells you if the account is actually profitable.
Pricing generally falls into three models: a flat monthly retainer, a percentage of ad spend (commonly 10 to 20 percent), or a hybrid of a base retainer plus a performance component. The right model depends on your catalog size, ad spend, and scope of work, which is why we scope pricing after an account audit rather than before one.
ACoS measures ad spend against ad-attributed sales only. TACoS measures ad spend against total sales, including organic. ACoS tells you if a campaign is efficient. TACoS tells you if the account as a whole is getting less dependent on paid traffic over time, which is the number that actually predicts long-term profitability.
Campaign restructuring can show efficiency improvements within two to three weeks. Listing and SEO changes typically take four to eight weeks to reflect in organic rank as Amazon’s algorithm reprocesses the updated content. A full account turnaround, where TACoS and contribution margin both move in the right direction, usually takes two to three months.
Yes. You own the Seller Central account, the advertising account, and every asset we create, including copy, images, and A+ Content. We work inside your account rather than asking you to hand over ownership.
It depends on the agency. We manage Amazon as the primary channel and can extend account and creative work to TikTok Shop, where buyer intent and content format overlap significantly with Amazon.
Ask for contribution margin alongside ACoS in every report. A campaign can look efficient on paper while the account loses money once fees, discounts, and returns come out of it. We include contribution margin, TACoS, and organic rank movement in every monthly report specifically so the answer does not rely on our word alone.
An Amazon marketing agency works best when the account underneath it is already sound. These are the most common services clients add alongside or before a full account engagement:
Backend attribute audits, natural-language copy rewrites, and Q&A seeding built for how Amazon's AI shopping assistant reads a listing, beyond how the search algorithm ranks it.
Title, bullets, description, and backend search terms built around keyword research and buyer intent.
Seven image-and-text modules replacing the plain-text description. Premium A+ adds full-width layouts, interactive modules, and embedded video.
