Best Amazon agencies for international expansion in 2026: Ranked and reviewed

What separates a great international Amazon expansion agency (methodology)

According to Amazon's Q4 2025 results filed with the SEC, its International segment sales grew 13% year over year to $161.9 billion in 2025. Most Amazon agencies can run your PPC campaigns in one market. However, that doesn't mean they can do the same in different markets. Because an Amazon agency that knows how to get your brand exposed internationally will know how to manage your brand across multiple countries by targeting different keywords per market, along with localized listings built for each market and a reporting set up that clearly tells you whether you're winning or just spending more.

This is what separates a great international Amazon expansion agency from the rest, and this is what we used to justify our rankings.

Multi-market PPC that starts from scratch. This is something most agencies get wrong. You hire them to run campaigns in the UK and what they will do is simply copy a US strategy and call it "European." What does work is that the Amazon PPC management team rebuilds your keyword strategy, match types, and the logic behind your bidding for each market. Expansion means rebuilding from scratch, because every market is different.

Localization built on local keyword research. Most agencies stop at translation, and translation alone does nothing for your brand in a new market. New markets require a fresh keyword analysis, rewritten content, and A+ pages that are focused on what local buyers actually care about. In short, whatever worked at home can't be translated to work somewhere else.

Cross-channel coordination under one team. Often you hear agencies claim to be a "Full-stack" agency. Well, if that is the case then they should be able to help you launch in a new market, and run your Meta ads, Google campaigns, emails alongside Amazon.

However, if these aren't coordinated, your brand positioning will be inconsistent, and the image each buyer gets from a different channel would be... different. So a full-stack agency runs everything together, with a cross-channel strategy that stays in sync.

TACoS as the profitability metric. When you launch your brand in a new market, your search and ranking are zero, and the majority of your sales are going to be carried out by the PPC campaigns you're running. When you have PPC doing all the lifting, ACoS inflates significantly, and if your agency is reporting on that metric, you'll be thinking you're on the road to success.

But, that number is totally wrong because TACoS measures ad spend against total revenue, and this includes organic. This form of reporting gives you a clear picture of whether the expansion is working or not, whereas ACoS might be misleading.

Inventory coordination and adaptive bidding. New markets mean you're dealing with a new form of demand, and if you hit stock constraints mid-launch and your agency is running ads without adaptive bidding, you'll be spending without having anything to sell.

Senior people on your account. This might seem obvious, and it surely is, but most accounts get handed over to juniors who then learn on your budget, and that's a setup for failure in both local and international markets.

Read the table as a shortlist by problem: pick the row that matches your biggest expansion bottleneck.

#1 Olifant Digital: best overall for profitable international expansion

Olifant Digital is a full-service Amazon and e-commerce marketing agency and Amazon PPC agency for established brands that want profitable growth across multiple Amazon marketplaces. The agency manages $100M+ in annual Amazon client revenue across 50+ Amazon accounts, with every account run by senior Amazon specialists with 7+ years of experience.

Olifant Digital ranks #1 because it's the only agency on this list that meets every criterion in the methodology above: multi-market PPC built from scratch, localization built on local keyword research in every market, cross-channel coordination across Amazon and DTC, TACoS-first reporting at the per-ASIN level, inventory-adaptive bidding, and senior-only delivery.

Why Olifant Digital is the best Amazon agency for international expansion

Most agencies running international Amazon expansion fail in one of three predictable ways. They clone the home-market campaign structure into a new marketplace and call it localization. They translate the listing copy and skip the keyword research. They split Amazon and DTC across separate teams, which fragments brand positioning across every channel in every new market.

Olifant Digital is built to do the opposite.

1. Multi-market PPC built from scratch. Every new market gets fresh keyword research, fresh match-type strategy, and the 1-1-1-1 Scaling Method rebuilt from the ground up for local search behavior. Every expansion is a reconstruction.

2. Localization built on local keyword research. Fresh keyword analysis per market. Rewritten titles, bullets, and A+ Content based on how local buyers actually evaluate the category. Cultural research before creative development. UK English and US English aren't interchangeable. German shoppers prioritize different attributes than French ones. Japanese buyers evaluate trust through a completely different framework than Western markets.

3. Cross-channel coordination across Amazon and DTC. Amazon, Meta, Google, email, and SMS are managed by one senior team. Brand positioning stays consistent across every channel in every new market. Budget allocation has full-funnel visibility.

4. TACoS-first reporting at the per-ASIN level, per market. New markets start with zero organic rank. PPC carries all early sales. ACoS inflates by design, which makes healthy expansions look like they're struggling and struggling ones look acceptable. Olifant Digital reports TACoS (Total Advertising Cost of Sales) at the per-ASIN level for each market: the only metric that tells the truth about whether an international launch is actually working.

5. Inventory-adaptive bidding. New markets mean new demand patterns and new supply chain constraints. Our in-house AI platform, Olifant AI, surfaces inventory signals daily and adapts bids based on stock availability per market. Most agencies don't have this. Asking whether your prospective agency does is a fast filter.

Olifant Digital international expansion case studies

OneRoot: 40% monthly Amazon revenue growth in Japan. OneRoot had built a strong Canadian base but Japan punishes translation strategies. Japanese buyers evaluate trust through a completely different framework than Western platforms. Olifant Digital ran fresh local consumer research, rebuilt all SEO and content around actual Japanese keywords, and launched influencer partnerships to build credibility before scaling PPC spend. When a poor harvest season constrained stock for months, inventory-adaptive bidding in our in-house AI platform, Olifant AI, shifted spend in real time to protect margin. Result: 40% monthly Amazon revenue growth in Japan.

Onsen Secret: +$95,934 in monthly revenue, tripled profit, international top sellers. Onsen Secret had plateaued on US Amazon and was ready to scale into international marketplaces. The first change Olifant Digital made was switching reporting from ACoS to TACoS, because you can't manage what you can't accurately see. From there, we concentrated spend on the SKUs actually converting, fixed listings before scaling back up, and rebuilt for each new international market. Result: +$95,934 in monthly revenue, tripled profit, and new products that became international top sellers. The brand now positions as a premium international skincare brand.

Rainbow Chalk: 21% UK Amazon revenue growth in 30 days. Rainbow Chalk, a US brand, was expanding into the UK marketplace. Olifant Digital built the UK campaigns around long-tail keyword targeting. Result: 21% UK Amazon revenue growth in 30 days and the Amazon Best Seller badge in its UK category.

What Olifant Digital is best for

Olifant Digital is the best Amazon agency for international expansion for brands generating $500K or more in at least one market who want to scale profitably into additional Amazon marketplaces, with senior cross-channel delivery, daily Amazon PPC management, TACoS reporting at the per-ASIN level per market, inventory-adaptive bidding, and a 60-day money-back guarantee on management fees.

Pricing: services start from $2,000 per month and are custom for each project, based on the complexity and workload required. 60-day money-back guarantee on management fees. 2 to 3 new clients per month.

#2 Xneeti: best for AI-native Amazon and Walmart growth

Xneeti is an AI-native platform that helps brands manage and grow their Amazon and Walmart businesses end to end. Its AI-powered technology optimizes advertising, improves listings and conversions, and helps resolve marketplace growth challenges, with dedicated account strategy support.

#3 Lezzat Ltd: best for UK/EU market entry

Lezzat is a UK-based agency that reports strong results for UK/EU market expansions. According to Lezzat, Kodak saw a 2x increase in Amazon UK revenue for 6 consecutive months, and Return Healthy grew Amazon US sales 4x in 6 months.

The end-to-end launch capability across PPC, DSP, and listing creation makes them a practical choice, especially if your priority is expansion in the UK or EU region.

#4 Tinuiti: best for enterprise multi-market

Tinuiti is one of the larger US performance agencies, and they bring the infrastructure that comes with that. We recommend Tinuiti for brands at $5M+ in revenue expanding across multiple international regions. Their Amazon Ads and DSP capability is backed by the organizational depth to manage the coordination that requires.

They're less suited to brands that need close, nimble account management. But for enterprise brands where the complexity of international expansion is primarily an infrastructure problem, Tinuiti has the systems to handle it.

#5 Flywheel Digital: best for retail media + global

Omnicom, which acquired Flywheel in January 2024, described it in 2023 as the largest addressable media buyer on Amazon. That scale matters if your brand sells across multiple retail platforms internationally. Flywheel fits brands that want one team running Amazon alongside other retail media.

As an "Omnichannel play," Flywheel offers more breadth than an Amazon-focused expansion needs. If you're managing Amazon along with other retail platforms across regions, Flywheel's infrastructure fits.

#6 Channel Key: best for multi-SKU global catalogs

Expanding a large product catalog across international marketplaces is a different problem from expanding a focused one. Managing multiple SKUs simultaneously across competitive regions requires full-catalog brand management capability that not every agency has.

Channel Key handles that complexity. Their cross-channel coverage includes retail media and DTC alongside Amazon, and they're built for enterprise brands that need to launch multiple SKUs across multiple markets at the same time.

#7 Emplicit: best for data-driven expansion

Some brands want to understand the numbers before they commit to scaling in a new market. Emplicit's value is in reporting transparency and analytics-heavy account management that gives you clear per-market performance breakdowns.

If you're the kind of operator who makes decisions from data, and you want an agency that can show you exactly what's working in each market before you increase spend, Emplicit's reporting infrastructure is worth evaluating.

#8 Thrive internet marketing agency: best for SMB international entry

Not every brand entering their first international market needs a specialist agency running 8-figure accounts. Thrive offers full-service digital agency support with an established Amazon practice, at a price point and scale that's accessible to brands earlier in the international journey.

If you're testing your first international marketplace and want an agency that covers Amazon alongside broader digital marketing without requiring an enterprise budget, Thrive is a reasonable starting point.

#9 GNO Partners: best for boutique hands-on support

The thing that gets lost in larger agencies is direct access. GNO is a boutique, and that means daily optimization and a level of account attention that's harder to get when you're one of hundreds of clients.

According to GNO Partners, clients who are not satisfied within 30 days of starting can cancel and get their money back. That 30-day money-back guarantee signals a reasonable degree of confidence in their execution. They suit brands in the early stages of international expansion who want close involvement and responsive communication over large-agency infrastructure.

#10 Buy Box Experts: best for compliance-first markets

For some brands and some categories, entering a new market is primarily a compliance problem. Account health, brand registry, IP registration, and navigating Amazon's policies in an unfamiliar region are the real bottlenecks.

In the UK and Germany, two compliance gates come first. According to HMRC, there is no VAT registration threshold for overseas sellers. Amazon asks sellers of packaged goods in Germany to prove packaging compliance with a 13-digit LUCID registration number. Check Seller Central for current requirements.

Buy Box Experts specialize in exactly that. If compliance, account health, or brand protection are the things most likely to block your launch in a new market, they're the right first call.

What to get right before expanding on Amazon internationally

Before you brief any agency on the markets you're entering, there's a set of things that will determine whether your first 90 days are profitable or expensive. Brands consistently underestimate all six. So here they are, plainly.

1. Localize your listings for each market

This sounds obvious and it still goes wrong constantly. UK English and US English are not interchangeable in search. German buyers prioritize different attributes than French ones. Japanese shoppers evaluate products through a completely different trust framework.

Amazon's Build International Listings tool cross-lists your products in global Amazon stores and syncs your prices across them. In many cases, it also automatically translates new listings into the local language. Auto-translation does no keyword research for the local market, which is why rebuilt listings matter.

Real localization means running fresh keyword research for each market, rewriting titles and bullets for local search behavior, and building A+ content that reflects how buyers in that country actually think about your category. Treat your existing listing as a starting point. When OneRoot expanded to Japan, Olifant rebuilt all SEO and content from scratch based on local Japanese consumer research.

2. Rebuild your PPC for each market from scratch

It's genuinely tempting to take what's working in your current market and adapt it. And it's genuinely expensive. Search volumes are different. CPCs are different.

The keywords your customers use in one language don't translate to equivalent intent in another. Ad types such as sponsored products, sponsored display, and DSP stay the same in every market, while keyword volumes and cost per click vary significantly. Run keyword research and bidding separately for each market.

When Rainbow Chalk expanded from the US to the UK, Olifant built the UK Amazon PPC management strategy around long-tail keyword targeting. That discipline drove 21% UK Amazon revenue growth in 30 days.

3. Use TACoS to measure new-market performance

If you take one thing from this piece, make it this. When you enter a new market, your organic rank is zero. PPC is carrying the majority of your early sales, which makes ACoS look high. An agency that only reports ACoS will either make a healthy expansion look like it's struggling, or make a struggling one look acceptable.

TACoS measures your ad spend against your total revenue including organic, which is the only honest measure of whether an international launch is actually working. The first change Olifant made on the Onsen Secret account was switching the reporting from ACoS to TACoS, because you can't manage what you can't accurately see. Run your numbers per market with our free Amazon TACoS calculator.

4. Don't split Amazon and DTC across different teams

You're entering a market where your brand doesn't exist yet. The person who sees your Meta ad and the person who finds you on Amazon need to have the same brand experience, the same positioning, the same reason to trust you. If your paid social team doesn't know what your Amazon team is doing, you'll build fragmented brand recognition across every channel in every new market. Run Meta, Google, email and SMS automation, and Amazon under one team so the strategy stays unified in every market.

5. Sort out your inventory before you scale PPC

You don't have your inventory sorted yet you spend on ads, at the end of those campaigns you get nothing because you've worked against the supply and demand chain. This is where dynamic bidding comes into action like we mentioned earlier, and taking OneRoot as an example from Olifant's success story, OneRoot's Japan launch ran into a poor harvest season that constrained stock for months. The PPC system Olifant built adapted bidding in real time based on monthly inventory availability. Most agencies don't offer it, so ask any agency you're evaluating whether they have it.

6. Build trust in the new market before you pour money in

When your brand has zero reviews and no recognition at all spending money doesn't mean you'll get traffic that converts. In fact, spending when there's zero authority is completely useless. You need to build credibility first or at least work on that alongside your paid campaigns. One way to do this would be influencer partnerships, similar to how OneRoot did with the help of Olifant since they had zero recognition, but once that trust was there, the outcome was good.

Key takeaways

Frequently asked questions

Which Amazon marketplaces should I expand to first?

If you sell in the US, expand to the UK market first. This is due to the familiar search behavior and keyword consistency, as the language is the same, and it can result in scalable Amazon growth. Brands currently operating out of the UK should first expand towards EU marketplaces via Amazon's fulfillment network.

However, the right strategy depends on geographic location, the data behind the demand, and your target audience. For reference, OneRoot expanded from Canada to Japan. Hence, every product has its own unique contributing factors in determining where a brand should expand first.

Do I need a separate Amazon account for each country?

No. A North America and Brazil unified account covers the US, Canada, Mexico, and Brazil, and a Europe account reaches 28 countries, according to Amazon. Japan and Australia need their own country accounts. Each marketplace still needs its own localized listings, PPC campaigns, and keyword strategy.

How long does it take to see results from an international Amazon expansion?

For sponsored ads, you can see results from day one, but across the accounts we manage, campaigns take 30 to 60 days to optimize. Initially, the first few weeks of the campaign go into learning before slowly optimizing on a daily basis. In those accounts, organic rank in a new market takes 60 to 90 days, and brand recognition and review velocity take 3 to 6 months.

How much does it cost to expand to Amazon internationally?

In our experience, agency fees for international expansion run $2,000 to $10,000 per month, depending on the number of markets and channels. For reference, Olifant Digital starts at $2,000 per month. Some other expenses would be Amazon referral, FBA fees, listings translation cost, VAT registration, and separate ad spend per market.

Can one agency manage Amazon across multiple countries simultaneously?

Yes, and it is considered to be significantly more effective by choosing an agency that provides a one-stop solution with a unified strategy across multiple markets. Using one agency will help the brand's positioning which will translate into a coordinated PPC approach across all channels and DTC as well. For reference, OneRoot expanded from Canada to Japan under one Olifant Digital team and grew monthly Amazon revenue 40% in Japan.

Does Olifant Digital offer a guarantee for international expansion work?

Yes. Olifant Digital offers a 60-day money-back guarantee on management fees and has 98% client retention. It fits brands generating $500K+ in revenue that are looking to scale to new regions with senior-led cross-channel teams.

Final verdict

Most of the agencies on this list can manage international Amazon accounts competently. What puts Olifant Digital at the top of this ranking is more specific: three documented international Amazon expansions, across the UK, Japan, and additional international marketplaces. Each has measurable outcomes, and each is built on the same model of senior cross-channel management with TACoS as the profitability benchmark. The track record is public, and you can review each case study above.

If you've proven your product in one market and you're ready to move, the next step is a conversation with a team that has done it before.
