MARKETPLACE GROWTH

Amazon US is the most competitive marketplace in the world — brands growing profitably there treat it as a separate business, not an add-on channel

Amazon holds 37% of US e-commerce, and Amazon Sponsored Products is a $35 billion advertising business. Brands that grow profitably on Amazon US understand the flywheel: reviews drive conversion, conversion drives organic rank, organic rank reduces advertising dependency. The two most common failure modes are running PPC without a review strategy — so ad spend goes to listings that cannot convert — and running Amazon as an afterthought to the DTC Shopify store, with no inventory sync and no cross-channel pricing discipline. We build the Amazon presence, the advertising structure, and the review acquisition system so that Amazon operates as a profitable channel with its own P&L.

Three types of US brands this work is built for

You have a proven Shopify store with consistent DTC revenue. You know Amazon is a channel you cannot ignore. You have not launched on Amazon because you are concerned about channel conflict, brand dilution, and losing pricing control. These concerns are real and manageable — they require deliberate decisions about pricing strategy, MAP enforcement, and brand presentation, not avoidance. This work handles the Amazon launch with those constraints factored in from the start.

You are running Sponsored Products and spending a material amount each month. ACOS is higher than you want it to be, and you are not confident the advertising is profitable at the product level. The problem is usually one of three things: the listing conversion rate is too low because of insufficient reviews or weak creative, the keyword targeting is too broad, or the ACOS target has not been set against actual product margins. This work audits the advertising account and the listings together to identify where the spend is going and whether the underlying listing can convert.

Your Amazon account and your Shopify store have different inventory counts, occasionally different prices for the same product, and different brand creative. Your marketing team treats Amazon as a separate project from DTC. Customers who discover you on Amazon and then visit your website see a different version of the brand. This creates both operational risk — oversell, pricing inconsistency — and brand risk. This work integrates the two channels so they operate as a coherent system.

Four marketplace problems keeping US brands from profitable Amazon growth

Running Amazon PPC without a review strategy

Sponsored Products campaigns drive traffic to listings. If a listing has fewer than 15 reviews, its conversion rate will be low regardless of how much traffic the campaigns send. Buyers searching on Amazon use review count and rating as a primary trust signal before clicking and before purchasing. Ad spend on a listing that buyers cannot trust enough to convert is wasted spend. A review acquisition strategy — Amazon Vine enrolment, post-purchase email sequences through Amazon's Request a Review feature, and product insert cards directing buyers to leave feedback — needs to run in parallel with the advertising campaign, not as an afterthought after ACOS has already been high for three months.

No A+ Content or Amazon Brand Story

Brand Registry-enrolled sellers can add A+ Content to every listing in their catalogue. Competitor listings with A+ Content convert at 3-10% higher rates than listings without it. Brand Story adds a persistent brand banner across all listings that links buyers to other products in the catalogue, increasing average order value and reducing the bounce rate to competitor listings. US brands that have not invested in A+ Content and Brand Story are presenting a weaker listing to buyers who are comparing multiple options on the same search results page.

Amazon and Shopify operating as separate silos

A brand with separate Amazon and Shopify operations has multiple points of failure: inventory counts that diverge, different pricing for the same product across channels, brand creative that is inconsistent, and no unified customer view. Customers who purchase on Amazon cannot be added to the DTC email list — that is a platform constraint. But inventory sync, pricing consistency, and brand presentation alignment are solvable. Treating Amazon and DTC as integrated parts of the same business requires deliberate architecture, not just good intentions.

No Sponsored Brands or Sponsored Display

Sponsored Products is the foundation of Amazon advertising, but it operates at the bottom of the funnel — it captures buyers already searching for a specific product. Sponsored Brands (including Sponsored Brands video) and Sponsored Display operate higher in the funnel. Sponsored Brands video places a 15-30 second autoplay video ad in search results, building category awareness among buyers who may not have been searching for the brand specifically. Sponsored Display retargets Amazon buyers who viewed the product listing but did not purchase. Brands running Sponsored Products only are not participating in the upper-funnel Amazon advertising that builds brand recognition in the category.

/ What we engineer

What a Marketplace Growth engagement covers

Each workstream is built by the team that audits it, and wired into the rest of your growth system.

Amazon US account and Brand Registry setup

For brands new to Amazon US, we set up the Seller Central account, complete Brand Registry, configure tax settings, and map the product catalogue to the correct Amazon categories. Brand Registry is the prerequisite for A+ Content, Sponsored Brands, Brand Story, and the Amazon Vine programme.

Product listing builds and optimisation

We write and optimise product titles, bullet points, descriptions, and backend search terms using Amazon US search volume data. Titles follow the Amazon formula for the product's specific category. Bullet points address the five highest-volume buyer questions in the category, derived from Amazon's "Customers Ask" data and competitor review mining.

Review acquisition strategy

Amazon Vine enrolment for new product launches: up to 30 Vine reviewer units for verified reviews prior to advertising launch. Amazon's Request a Review feature configured and scheduled for every order. Product insert strategy: compliant insert cards that direct buyers to leave a review through the proper Amazon channel without incentivising a positive review (which violates Amazon's terms of service).

A+ Content and Brand Story

A+ Content designed and uploaded for all listings in the catalogue. Brand Story module built and applied to the full catalogue. Both designed with lifestyle imagery and copy that is consistent with the brand's DTC presentation.

Sponsored Products, Sponsored Brands, and Sponsored Display setup and management

Full-funnel Amazon advertising build. Sponsored Products: automatic campaigns for keyword discovery, manual campaigns for target keywords, ACOS targets by product. Sponsored Brands: headline search ads with brand logo and custom headline, Sponsored Brands video where applicable. Sponsored Display: product retargeting for listing viewers who did not purchase. All campaigns managed with weekly bid reviews.

Shopify-Amazon inventory sync and pricing alignment

Inventory sync configured between Shopify and Amazon Seller Central using a third-party connector (Linnworks, Skubana, or a comparable tool). Pricing alignment review: MAP policy documented, Amazon pricing set to be consistent with or above DTC pricing to avoid channel conflict. Order management from both channels unified in a single view.

Amazon P&L reporting

Monthly Amazon P&L covering: gross revenue, Amazon fees (referral, FBA, storage), advertising spend, net revenue, and contribution margin by product. Amazon P&L reported separately from DTC P&L so the channel's profitability is visible independently.

Four measurable outcomes from marketplace optimisation

Before
After
BeforeSponsored Products campaigns drive traffic to listings. If a listing has fewer than 15 reviews, its conversion rate will be low regardless of how much traffic the campaigns send. Buyers searching on Amazon use review count and rating as a primary trust signal before clicking and before purchasing. Ad spend on a listing that buyers cannot trust enough to convert is wasted spend. A review acquisition strategy — Amazon Vine enrolment, post-purchase email sequences through Amazon's Request a Review feature, and product insert cards directing buyers to leave feedback — needs to run in parallel with the advertising campaign, not as an afterthought after ACOS has already been high for three months.
AfterOnce a listing crosses the 15-review threshold — and particularly once it reaches 30-50 reviews with a 4-star-plus rating — advertising conversion rates improve materially. The same Sponsored Products campaign that was generating a 50% ACOS with 5 reviews will generate a meaningfully lower ACOS with 40 reviews, because the listing can now convert the traffic it receives. Review acquisition is not a vanity exercise; it is the prerequisite for efficient advertising.
BeforeBrand Registry-enrolled sellers can add A+ Content to every listing in their catalogue. Competitor listings with A+ Content convert at 3-10% higher rates than listings without it. Brand Story adds a persistent brand banner across all listings that links buyers to other products in the catalogue, increasing average order value and reducing the bounce rate to competitor listings. US brands that have not invested in A+ Content and Brand Story are presenting a weaker listing to buyers who are comparing multiple options on the same search results page.
AfterA product detail page with A+ Content and a Brand Story module presents a more complete picture of the product and the brand than a bare-bones listing. Buyers who would have left the listing because they were not confident enough to purchase convert at a higher rate. Brand Story links to other products in the catalogue, keeping buyers within the brand's product range rather than returning to the search results to find a competitor.
BeforeA brand with separate Amazon and Shopify operations has multiple points of failure: inventory counts that diverge, different pricing for the same product across channels, brand creative that is inconsistent, and no unified customer view. Customers who purchase on Amazon cannot be added to the DTC email list — that is a platform constraint. But inventory sync, pricing consistency, and brand presentation alignment are solvable. Treating Amazon and DTC as integrated parts of the same business requires deliberate architecture, not just good intentions.
AfterSponsored Products captures buyers who are already searching for the product. Sponsored Brands and Sponsored Display reach buyers who are in the category but not yet searching for the specific product. A brand visible at all three funnel stages on Amazon — organic search, Sponsored Products, and Sponsored Brands — holds more of the category's buyer attention than a brand that only appears when a very specific query is typed.

AfterA channel that is tracked and managed separately from DTC has a profitability floor. When Amazon contribution margin drops — because fees increase, advertising efficiency declines, or a competing listing undercuts on price — the P&L makes it visible before it becomes a problem. Brands that run Amazon as an add-on to DTC without a separate P&L frequently discover that the channel has been unprofitable for months before anyone notices.

/ How it works

How a Marketplace Growth engagement runs

  1. Amazon audit Days 1-7

    We audit the brand's existing Amazon US presence: listing quality, review count and rating by product, Brand Registry status, A+ Content coverage, advertising account structure and ACOS by campaign, Shopify-Amazon inventory sync status, and pricing consistency across channels. For brands not yet on Amazon US, we audit the product catalogue and competitive landscape for the launch category. The audit output is a prioritised gap analysis.

  2. Listing builds, review strategy setup, and ad account restructure Days 8-21

    Listings are rewritten or built from scratch. Amazon Vine is submitted for eligible products. Request a Review automation is configured. A+ Content and Brand Story are designed and submitted. The advertising account is restructured with new campaign architecture or built from scratch. Shopify-Amazon inventory sync is configured and tested.

  3. Advertising launch and Vine reviewer fulfilment Days 22-30

    Sponsored Products, Sponsored Brands, and Sponsored Display campaigns launch. Vine reviewer units are fulfilled. The first week of advertising data is monitored for bid, targeting, and budget issues. ACOS is tracked daily against targets.

  4. Ongoing optimisation Month 2 onwards

    Monthly review covers: advertising ACOS by product and by campaign type, organic rank movement for primary keywords, review count and rating progression, A+ Content conversion rate impact, Amazon P&L versus DTC P&L. Sponsored Brands video is added once the brand has 15-plus reviews and a stable conversion rate. Catalogue expansion to new ASINs follows the same listing and advertising build process.

Marketplace Growth — US FAQs

Straight answers on scope, timelines and cost. Anything else, ask us directly.

Ask us directly
How many reviews does an Amazon listing need before PPC becomes profitable?

There is no exact universal threshold, but most category data points to 15 reviews with a 4-star-plus rating as the floor below which advertising conversion rates are low enough to make profitability difficult regardless of how the campaigns are structured. At 30-50 reviews, conversion rates improve meaningfully, and at 100-plus reviews, a listing is typically competitive with established category players. The review count where PPC becomes profitable varies by category — in highly competitive categories with high buyer expectations, the threshold is higher; in niche categories with fewer competing listings, it can be lower.

What is A+ Content and how much does it improve Amazon conversion rates?

A+ Content is an enhanced product page feature available to Brand Registry-enrolled Amazon sellers. It replaces the standard text description section with structured visual modules: brand story, lifestyle imagery, feature highlight banners, and product comparison charts. Amazon's published data indicates that A+ Content improves conversion rates by 3-10% on average. The actual improvement for any specific listing depends on how weak the baseline listing was, how relevant the A+ Content is to the buyer's decision-making process, and how the product's category and price point affect buyer diligence levels.

How do I sync Shopify inventory with Amazon US to prevent oversells?

Shopify does not natively sync inventory with Amazon US, so a third-party multi-channel inventory management tool is required. Linnworks, Skubana, Sellbrite, and Codisto are commonly used options that sync stock quantities between Shopify and Amazon Seller Central in near real time. When a unit sells on either channel, the available quantity updates on the other within minutes. These tools also provide a unified order management view across both channels, which simplifies fulfilment and customer service operations.

What ACOS target is realistic for Amazon Sponsored Products in a competitive US category?

Target ACOS should be calculated from the product's gross margin, not from a generic benchmark. A product with a 60% gross margin can sustain a higher ACOS than a product with a 30% gross margin. The breakeven ACOS equals the product's gross margin percentage — advertising spend above that level means the advertising itself is generating a net loss on the units it drives. In practice, brands target ACOS at 50-70% of their gross margin to leave room for margin after advertising. In highly competitive US categories, early-phase ACOS may need to exceed the target to build sales velocity and review count before organic ranking reduces advertising dependency.

What is the difference between Sponsored Products, Sponsored Brands, and Sponsored Display on Amazon?

Sponsored Products are keyword-targeted ads that appear in search results and on product detail pages, linking directly to the product listing. They operate at the bottom of the funnel, capturing buyers who are already searching for a specific product type. Sponsored Brands appear at the top of search results and feature the brand logo, a custom headline, and up to three product images — they build brand awareness in the category and direct buyers to a brand store or landing page. Sponsored Display ads appear on and off Amazon, targeting buyers who have viewed the product listing or similar products, functioning as retargeting. A complete Amazon advertising strategy uses all three formats, with Sponsored Products as the foundation and Sponsored Brands and Sponsored Display as the upper and mid-funnel complements.
