Your products are good.
Your Amazon channel is bleeding profit.
Most brands don't have an Amazon strategy problem — they have an execution problem. Every week without dedicated management, the same five leaks compound:
Ad spend creeps up while ACOS climbs and ROAS quietly erodes.
Listings fall out of compliance and get suppressed without warning.
You lose the Buy Box and don't find out until sales drop.
Cases sit open for weeks in a support queue that goes nowhere.
The catalog grows faster than anyone can manage it.
Daily bid optimisation that drives ACOS down — not up.
Proactive compliance monitoring before suppression hits.
Buy Box recovery strategies — we catch the loss, not you.
Dedicated case management — open tickets get closed, fast.
Catalog architecture that scales — no matter how fast you grow.
You need an Amazon agency that operates the channel for you — measured on the one number that matters: profitable growth.
Amazon agencies talk about results. Here are ours.
Why Engin8 is different
We're operators, not order-takers.
Engin8 was founded by Lee Loree and Robert Ferreira, the operators behind Seller Investigators (acquired by Carbon6) — people who built and scaled Amazon brands before they ever managed them for others. We've sat in your seat. That's why we manage your account the way an owner would, not the way a billable-hours vendor does.
Profit-first advertising. We optimize to your margin, not a screenshot-friendly ROAS number.
Full-channel ownership. One accountable team for ads, content, catalog, compliance, and strategy.
Active management, not a ticket queue. Deliberately low client-to-specialist ratio.
Scale you can lean on. 300+ specialists, $1B+ GMV — enterprise depth with boutique responsiveness.
Engin8 Ops Tool. Proprietary platform: real-time campaign tracking, split-test results, full task transparency.

Engin8 vs. the alternatives
One team that owns everything vs. three that own nothing
| Engin8 | Typical PPC-only agency | In-house hire | |
|---|---|---|---|
| Scope | Full channel: ads, listings, catalog, compliance, strategy | Ads only | Limited to one person's skill set |
| Ramp time | Days (team already trained) | Days–weeks | 1–3 months to hire + onboard |
| Cost | One predictable fee | Fee + the gaps you still cover | $70k–$120k+ salary + benefits |
| Account health / reinstatements | ✅ Core service (+15 pts avg) | ❌ Usually out of scope | ⚠️ Depends on hire |
| Bench depth | 300+ specialists | Small team | Single point of failure |
| Accountability | One team owns the number | Split across vendors | Internal |
A full-service Amazon agency covers every growth lever simultaneously — Amazon PPC management, creative services, account health, and strategy. PPC-only agencies and single in-house hires leave gaps that compound over time. Amazon represents nearly half of all U.S. e-commerce — brands that treat it as a secondary channel consistently underperform those with dedicated full-channel management.
Performance Benchmarks
How Amazon Agencies Improve PPC Performance
Amazon PPC (pay-per-click) is the advertising system on Amazon where brands bid on keywords to show ads in search results and product pages, paying only when a shopper clicks. A managed agency typically achieves significantly better results than self-managed campaigns.
- Audit existing campaigns — identify wasted spend, keyword gaps, and structural inefficiencies
- Keyword discovery and segmentation — build a tiered strategy from branded, category, and competitor terms
- Campaign architecture build — separate campaigns by match type, intent, and product margin
- Bid optimization cadence — daily adjustments based on search-term data, dayparting, and placement performance
- AMC attribution analysis — close the loop on cross-campaign performance and audience overlap
| Metric | Industry Average | With Managed Agency |
|---|---|---|
| ACoS | 30–35% | 18–25% |
| ROAS | 3–4× | 5–8× |
| CTR | 0.3–0.5% | 0.6–1.0%+ |
| Conversion Rate | 10–15% | 15–25%+ (with optimized listings) |

"Listings optimized for both Amazon SEO and conversion consistently outperform those optimized for one or the other. Keyword-rich titles only work when paired with conversion-driving imagery and A+ Content — a full-service agency moves all levers simultaneously."
Decision Guide
How to Choose the Best Amazon Agency
Not all Amazon agencies are equal. Before signing, ask these five questions — the answers will quickly separate genuine specialists from generalists who've added Amazon to their service list.
- Are you a verified Amazon Ads Partner? (Verifiable at advertising.amazon.com/partners)
- Do you specialize in my product category? (Category expertise affects keyword strategy and content)
- What is your client-to-specialist ratio? (High ratios = low attention per account)
- How do you report results? (AMC-level attribution vs. vanity metrics like impressions)
- What are your contract terms? (Month-to-month after onboarding vs. 12-month lock-ins)
| Criteria | Green Flag | Red Flag |
|---|---|---|
| Amazon Ads Partner status | ✅ Verified Partner in directory | ❌ Not in partner directory |
| Pricing model | Fixed retainer + optional performance component | Commission-only or % of ad spend only |
| Reporting | AMC-level attribution, real KPIs (ACoS, ROAS, TACoS, revenue) | Vanity metrics (impressions, followers, clicks only) |
| Contract terms | Month-to-month after 90-day onboarding | 12-month lock-in with no exit clause |
| Scope | Full-service: ads + content + account ops | PPC-only or content-only |
| Proof | Named case studies with metrics and dollar figures | Testimonials without measurable data |
"Amazon agencies that only do PPC leave significant growth on the table. Advertising performance is directly tied to listing quality, review count, and account health. Only a full-service team can move all four levers simultaneously — and hold one number accountable."

Amazon Ecosystem Explained
Key Terms Every Brand Should Know
Before hiring an Amazon agency, understanding the core platform concepts helps you ask the right questions and evaluate results accurately.
What is an Amazon agency?
An Amazon agency is a specialized firm that manages a brand's Amazon channel end-to-end — including advertising, listing optimization, account health, content, and operations — to maximize revenue and profitability on the platform. A full-service Amazon agency owns the entire channel rather than a single function, giving the brand one accountable team instead of stitching together multiple point vendors.
- ✓Manages Amazon advertising (Sponsored Products, Brands, Display, DSP) to a profit target
- ✓Optimizes listings (titles, bullets, A+ Content, images) for organic ranking and conversion
- ✓Maintains account health, compliance, and Brand Registry enrollment
- ✓Manages catalog structure, inventory operations, and FBA forecasting
- ✓Plans promotions, Prime Day, and Q4 / BFCM peak strategy
- ✓Reports on profit metrics and drives a quarterly growth roadmap
What is Amazon DSP?
Amazon DSP (Demand-Side Platform) is a programmatic advertising platform that allows brands to buy display and video ad placements both on Amazon and across the web, targeting Amazon audience segments. DSP is used for upper-funnel brand awareness and retargeting campaigns — reaching shoppers who viewed your products but didn't purchase. Unlike Sponsored Ads, DSP does not require keyword bids; it targets audiences based on browsing and purchase behavior.
What is Amazon Marketing Cloud (AMC)?
Amazon Marketing Cloud (AMC) is a secure, privacy-safe data clean room that allows advertisers to analyze Amazon Ads data at the user-journey level. AMC enables cross-channel attribution, audience building, and campaign optimization insights not available in standard Amazon Ads reporting. It reveals the full path-to-purchase — how many touchpoints a shopper had before converting — helping agencies allocate budget more accurately across Sponsored Ads and DSP.
What is Amazon Attribution?
Amazon Attribution is a measurement solution that tracks how off-Amazon marketing channels (Google Ads, Facebook, email, influencers) drive traffic and conversions on Amazon. It assigns unique tracking tags to external links, allowing brands to see which off-Amazon channels drive Amazon sales. This is critical for brands running multi-channel campaigns who need to know whether their Google traffic is converting on Amazon or being lost.
What is Amazon A+ Content?
Amazon A+ Content (formerly Enhanced Brand Content) replaces the plain-text product description with rich branded modules — comparison charts, lifestyle imagery, feature callouts, and brand story sections. It is available exclusively to Brand Registry members. Premium A+ Content (an upgraded tier) can increase conversion rates by 3–10% vs standard listings and includes larger modules, interactive hotspots, and video. Premium A+ is unlocked once a brand has an approved history of standard A+ submissions.
What is Amazon Brand Registry?
Amazon Brand Registry is Amazon's program for brand owners with an active registered trademark. Enrollment unlocks access to A+ Content, Sponsored Brands ads, Brand Store, Amazon Posts, Amazon Vine, and enhanced brand protection tools (Report a Violation, Automated Protections). Without Brand Registry, brands cannot run Sponsored Brands campaigns or create A+ Content, which directly limits advertising reach and listing conversion rates.
ACoS, ROAS, and TACoS — Defined
ACoS (Advertising Cost of Sale)
The percentage of attributed sales revenue spent on advertising. Calculated as: Total Ad Spend ÷ Total Attributed Sales × 100. A managed Amazon agency typically targets an ACoS of 15–25% depending on your margin and growth stage. Lower ACoS = more efficient ads.
ROAS (Return on Ad Spend)
The inverse of ACoS — how much revenue you earn for every dollar spent on ads. Calculated as: Attributed Sales ÷ Ad Spend. A ROAS of 5× means you earn $5 for every $1 spent. Industry average on Amazon is 3–4×; managed accounts typically achieve 5–8×.
TACoS (Total Advertising Cost of Sales)
Ad spend as a percentage of total channel revenue (not just ad-attributed sales). TACoS accounts for the halo effect of advertising on organic sales, making it the most complete measure of advertising efficiency for Amazon brands.
Amazon Seller Central vs. Vendor Central: What's the Difference?
Amazon Seller Central (3P) is for brands that sell directly to customers through Amazon's marketplace. The brand controls pricing, fulfillment, and inventory. Available to any registered seller.
Amazon Vendor Central (1P) is an invite-only platform where Amazon purchases inventory wholesale from the brand and resells it. Amazon controls the retail price. Vendor Central unlocks additional advertising formats (AVN negotiations, Display Buy Box) but removes pricing control.
A hybrid approach uses both simultaneously — selling some SKUs through Vendor Central while maintaining a 3P presence for price-sensitive or high-margin products. Each model requires different operational and advertising strategies.
When should a brand hire an Amazon agency?
A brand should consider hiring an Amazon agency when: it is spending $5,000+ per month on Amazon ads without consistent profitability; Amazon represents more than 20% of revenue but lacks dedicated management; listings are suppressed or account health is declining; or the in-house team lacks Amazon-specific expertise in PPC, SEO, and compliance. For brands doing $500K+ annually on Amazon, a full-service agency almost always delivers better ROI than in-house management — Amazon expertise is too broad for one or two people to cover well.
FAQ
Amazon agency questions, answered
Everything brands ask before signing. No fluff — just straight answers.

ACoS (Advertising Cost of Sale) is the percentage of attributed sales revenue spent on advertising — calculated by dividing total ad spend by total attributed sales. A managed Amazon agency typically targets an ACoS between 15–25% depending on the brand's margin and growth stage. Lower ACoS means more efficient advertising, but the right target varies by category and business model.
Amazon DSP (Demand-Side Platform) is a programmatic advertising platform that lets brands buy display and video ads both on Amazon and across the web, targeting Amazon audience segments. DSP is ideal for brands with $25K+ monthly ad spend who want to build awareness, retarget past viewers, and reach competitor shoppers. It requires a minimum spend commitment and works best when paired with an active Sponsored Ads strategy.
Amazon Marketing Cloud (AMC) is a secure, privacy-safe data clean room that allows advertisers to analyze Amazon Ads data at the user-journey level. AMC enables cross-channel attribution, custom audience building, and optimization insights not available in standard Amazon Ads reporting — such as how many ad touchpoints a shopper had before purchasing. Engin8 uses AMC analysis as part of full-service DSP and Sponsored Ads management.
Amazon Brand Registry is Amazon's program for brand owners with an active registered trademark. Enrollment unlocks A+ Content, Sponsored Brands ads, Brand Store, Amazon Posts, and enhanced brand protection tools (Automated Protections, Report a Violation). Without Brand Registry, brands cannot run Sponsored Brands campaigns or create A+ Content — directly limiting both advertising reach and listing conversion rates. Engin8 handles full enrollment and enforcement as part of account management.
Amazon Seller Central (3P) is for brands that sell directly to customers through Amazon's marketplace — the brand controls pricing, inventory, and fulfillment. Amazon Vendor Central (1P) is an invite-only platform where Amazon purchases inventory wholesale from the brand and resells it. A hybrid approach uses both simultaneously. Each model requires different operational and advertising strategies; Engin8 manages Seller Central, Vendor Central, and hybrid accounts.

What Our Clients Say
Trusted by brands that needed more than just PPC.
"Engin8 took over a suppressed catalog that was bleeding revenue, reinstated our flagship ASINs, and rebuilt the account from the ground up — recovering $240K in annual revenue and turning Amazon back into our most profitable channel."
"Our ACOS dropped from 38% to 21% in the first 60 days. What impressed me most was that they didn't just fix the ads — they found and fixed the listing issues that were dragging conversion down at the same time."
"We'd been managing Amazon ourselves for three years and thought we knew what we were doing. Engin8's audit showed us gaps we had no idea existed. Within one quarter, Amazon went from our worst-performing channel to our best."
