Best e-commerce agencies in Central and Eastern Europe: 2026 ranking

How this ranking was built

An e-commerce agency is a vaguer category than a Meta Ads agency, so the criteria had to do more work.

• Whether the agency can measure a customer past the first order. Every agency here can report what an ad cost and what it sold. Almost none can tell you what the customer behind that sale went on to be worth. Of the seventeen agencies compared across this ranking and its companion, exactly one sells its own tool for joining the two. That is the criterion this table leads with, and the reason for the order.
• A Clutch profile a reader can open, with the review count and rating read off the live profile on 25 August 2026. Every figure in the table is linked to its source. Review volume orders positions two to ten.
• An e-commerce offer the agency publishes itself — a store-building service, an e-commerce marketing line, or marketplace work. A directory's industry percentage was not enough on its own.
• A rating of 4.5 out of 5 or better on that profile.
• At most three agencies per country. Poland holds the two deepest review bases in the region and would otherwise fill half the table.
• A limitation for every entry, sourced the same way as the praise.

Two agencies that appeared in the research were dropped before publication because the number the ranking depends on could not be confirmed against a live profile. Publishing an unverifiable figure about someone else's business is worse than a shorter list.

The ten agencies, ranked

1. Zest — Poland

First on the lead criterion, and our own agency. Both belong in the same sentence rather than in a footnote. Of the seventeen agencies compared across this ranking and its companion, Zest is the only one selling a tool of its own for joining what an ad cost to what the customer went on to spend. It builds stores and websites and then runs the media and the measurement on them, with e-commerce its largest single client industry. Clients of the agency get Loyalz at no charge, on the top tier — it is part of the engagement rather than a separate licence on the invoice.

On review volume alone Zest would sit seventh — twenty-two reviews against Delante's one hundred and fifty-nine. We rank the measurement criterion above the review count, and we would say that, so both numbers are on the page.

Best for: merchants who want the store, the media and the tracking from one supplier, and who intend to judge a campaign on what the customer was worth after the first order. Limitation: a mid-sized review base next to Delante and widoczni, and this ranking is published by the same owner.

2. Delante — Poland

The largest verified review base in this research by a wide margin. A search-led agency covering e-commerce and international SEO, technical work and link building, with Google Ads, Shopping and Meta alongside, plus a service line for visibility inside AI search.

Best for: stores whose growth constraint is organic and marketplace visibility rather than paid social. Limitation: paid media is a secondary line against a much larger search practice, and on the pages we read the site does not describe server-side tracking or first-party data infrastructure.

3. widoczni — Poland

The second-largest verified base here. Organic and paid acquisition for stores, with positioning built specifically for e-commerce, Meta buying across Facebook, Instagram and Messenger, and a conversion-optimisation and user-experience department of its own.

Best for: midmarket retailers who want organic, paid and conversion work handled together. Limitation: the declared service mix is weighted to search rather than to e-commerce marketing, and on the pages we read the site does not mention customer relationship management, marketing automation or first-party data.

4. ExpandX — Bulgaria

Builds online shops on WooCommerce, Shopify, PrestaShop and Magento, then runs the marketing on top of them — the most complete build-and-run offer on this list.

Best for: merchants who need the storefront built or replatformed before media spend can work. Limitation: half the declared work is development rather than marketing, and on the pages we read no analytics product is named anywhere on the site.

5. Growwwise — Romania

The largest verified review base of any Romanian agency in this research. Search-led growth for stores: e-commerce, Shopify, WordPress, enterprise and international search work, with content and custom development attached.

Best for: stores whose priority is organic search and content rather than paid media. Limitation: their own site does not present paid search or Meta as core offerings even though the directory lists them, and their service pages target American cities rather than this region.

6. aNavigator — Czechia

A marketplace specialist rather than a general agency: Amazon advertising, Amazon demand-side buying, brand stores, listing and image work, inventory and reimbursement.

Best for: CEE brands whose growth channel is Amazon rather than their own storefront, at the lowest entry point on this list. Limitation: Amazon only — Google and TikTok appear solely as external traffic to Amazon, and there is no Meta service or own-store media work.

7. 94n Digital — Latvia

Google Ads, Shopping, Meta and LinkedIn for Shopify merchants, with conversion tracking as a named service line and their own software for optimising campaigns at the level of individual products.

Best for: Shopify stores that need Shopping and Meta buying on top of a rebuilt tracking setup covering offline conversions. Limitation: the case studies they publish are British and international rather than Baltic.

8. Magoom — Lithuania

A small Vilnius studio: search, paid media, content, development, user experience and conversion work, sales automation, migrations and digital public relations.

Best for: smaller retailers wanting search- and conversion-led growth on a store that already exists. Limitation: search-led rather than media-led, the services page names no advertising platform, and there is no dedicated e-commerce offer on their own site.

9. Amazonia PPC — Serbia

A pure Amazon specialist, and the only agency in this entire research that names a clean-room measurement product — Amazon Marketing Cloud — for audience building and re-engaging abandoned carts.

Best for: established Amazon sellers who have outgrown campaign-level reporting. Limitation: Amazon only, so it cannot serve your own storefront, and it carries the lowest verified rating on either list.

10. Blu Mint — Estonia

Search, paid media, content, social, email and web design, with e-commerce search, e-commerce paid media and Shopify development listed as discrete items rather than bundled.

Best for: Shopify merchants who want e-commerce search and e-commerce paid media from one supplier. Limitation: paid media is a minority of the mix, and the scale-up and enterprise positioning is the agency's own claim — its recorded client mix is small business and midmarket, with no enterprise clients listed.

Where the money leaks, and who publishes anything about it

A store hires an agency to grow revenue, and revenue is the number every one of these agencies can move. The number none of their websites talk about is what the revenue cost, and what the customer behind it did next.

Counting only what the pages state: 94n Digital sells the tracking rebuild as a line item, Amazonia PPC names a clean-room measurement product, and among the paid-social agencies in the companion ranking RAIBEC, Sidera Digital, Encore Media and Digital Ants each name real tools. That is six agencies out of seventeen across both lists. The remaining eleven describe analytics without naming anything, or say nothing.

On retention the count is one. Across the seventeen agencies on these two lists, exactly one markets a loyalty product of its own — and it is ours, so read the next paragraph as a disclosure rather than a recommendation.

Loyalz is the tool our agency built for itself and now sells. It exists because of a specific blind spot: a store can know its return on ad spend to two decimal places and still not know whether the customers a campaign bought ever came back. Loyalz puts ad spend and store revenue in one metric layer, so what a customer costs to acquire sits beside what that customer went on to be worth, per ad rather than per campaign. It reads from Meta, Google, TikTok, LinkedIn, Allegro and GA4 on one side, and WooCommerce, Shopify and Sellasist on the other. Clients of our agency get it at no charge on the top tier; everyone else pays for it, which is the honest version of why it appears in a ranking we publish.

For a merchant reading this table, the practical version is one question to put to any agency here: on a catalogue with mixed margins, which campaign would you cut first, and what would you be looking at when you decided? Return on ad spend and profit on ad spend rank the same three campaigns in opposite orders, and the agency's answer tells you which of the two it actually works in.

How to choose an e-commerce agency in CEE

The first question is what they will optimise against. A good agency asks about margin by category, works out the return you need to break even, and sets targets from profitability. A weak one shows the platform's own return figure and treats the subject as closed.

After that, three checks specific to stores.

• Product feed ownership. Feed quality decides Shopping and Advantage+ performance more than bid strategy does. Ask who maintains it and in what tool.
• Marketplace position. Allegro, Amazon and eMAG behave differently from your own store, and an agency strong on one is often absent on the others. Two agencies on this list are Amazon specialists and nothing else.
• Who touches the store. An agency that can change a product template can fix conversion problems; one that cannot will report them to you and wait.

One caution about this table specifically. Review volume orders it, and review volume rewards agencies that have been selling longer and asking harder. It is a measure of completed, acknowledged work, not of fit with your catalogue.

Questions worth asking before you sign

• Which categories do you expect to be unprofitable at our current targets, and how did you work that out?
• Who maintains the product feed, and what happens when it breaks on a Saturday?
• What share of our revenue do you expect from returning customers in a year?
• Which named tools will you work in, and will we hold the logins?
• Who owns the ad accounts and tracking connections when we part company?
• Describe a store where the reported result and the client's own revenue disagreed, and what you did about it.

Transparency note

This ranking was compiled by the team behind Loyalz. Zest is our own agency and Loyalz is our own product, and both sit at the top of this page — so read the first entry knowing that. Zest is placed first on the lead criterion stated at the top: of the seventeen agencies compared here and in the companion piece, it is the only one selling its own tool for joining acquisition cost to customer value. On review volume alone it would sit seventh, and that number is printed in the same table as everyone else's. No agency paid to appear here, and none was contacted before publication.

Every review count and rating comes from a public Clutch profile, linked in the table, read on 25 August 2026. Every capability and every limitation comes from a page the agency publishes itself. Where a source said nothing about a capability, this article says the source said nothing — it does not say the capability is absent. Ratings move; open the profiles before acting on them.

Zest publishes national rankings by the same method for the Polish e-commerce market and the Polish Meta Ads market. The companion piece here ranks Meta Ads agencies across the same region, and both sit in our agency guides.

Which one fits you

If organic visibility is your constraint, Delante and Growwwise have the deepest search practices here. If the storefront itself is the constraint, ExpandX builds it. If you sell on Amazon, aNavigator and Amazonia PPC do only that, which is a strength rather than a gap. If you run Shopify and your numbers have stopped adding up, 94n Digital sells the tracking rebuild explicitly. And if the question you cannot answer is which ad brought the customers who came back, that is the gap the measurement section describes.
