Best Meta Ads agencies in Central and Eastern Europe: 2026 ranking

How this ranking was built

Six criteria, applied in this order.

• 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, because the tool for it does not exist in most stacks. 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 rather than a directory summary. Every figure in the table was read on 25 August 2026 and every one of them is linked. Review volume orders positions two to ten.
• A Meta advertising offer named on a page the agency publishes itself, never inferred from a service-mix percentage on a directory.
• A rating of 4.5 out of 5 or better on that profile.
• At most three agencies per country, so this stays a regional list. Poland has the deepest review bases in the region and would otherwise take half the table.
• A limitation for every entry, sourced the same way as the praise.

Agencies whose Clutch profile shows no reviews were left out rather than placed at the bottom. That is not a judgement on their work; the ordering metric simply does not exist for them. Several reappear further down, where their own sites carry real evidence.

The ten agencies, ranked

1. Zest — Poland

First on the lead criterion, and our own agency. Both of those 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 that sells a tool of its own for connecting what an ad cost to what the customer it brought went on to spend. It also runs media buying, creative production and the tracking layer as one team across Google, Meta, TikTok and LinkedIn, and hands over ad accounts, pixels and Conversions API setups as the client's property from the first day. 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 eighth here — twenty-two reviews against ExpandX's seventy-two. We rank the measurement criterion above the review count, and we would say that, so both numbers are on the page and you can weigh them yourself.

Best for: brands that want the buying, the creative and the measurement from one supplier, and that intend to judge campaigns on what the customer was worth rather than on what the platform reported. Limitation: a mid-sized review base for the region, and this ranking is published by the same owner.

2. ExpandX — Bulgaria

The largest verified review base on this list. ExpandX builds the storefront and then runs the media on it, advertising on Facebook, Instagram, Google, YouTube, TikTok and LinkedIn, with WooCommerce, Shopify, PrestaShop and Magento named as build platforms.

Best for: a brand that needs the shop built or replatformed before spend can work. Limitation: development is the larger half of what they do, and on the pages we read no analytics product is named anywhere on the site.

3. Marketing Deck — Romania

The most paid-social-weighted agency in the table, with its own video studio in Bucharest and campaigns run for clients in ten countries outside Romania. Meta Badged Partner since 2025, Google Partner since 2020.

Best for: advertisers whose Meta results are capped by creative volume rather than by budget. Limitation: their Clutch mix carries no e-commerce marketing line at all, so this is a paid-social shop rather than a store specialist.

4. MTA Digital — Poland

Full-funnel paid media for consumer and e-commerce brands, with Meta alongside Google, TikTok, Pinterest and programmatic, and creative strategy attached. E-commerce is 80 percent of the client base, the highest share of any full-service buyer here.

Best for: midmarket online retailers who want one paid-media and creative partner. Limitation: on the pages we read, the site describes channels and analytics services but names no server-side tracking, attribution modelling or first-party infrastructure.

5. 94n Digital — Latvia

A Riga-registered buyer running Google Ads, Shopping, Meta and LinkedIn, with conversion tracking as its own service line covering direct platform integrations and offline conversions — one of the few agencies on either list to sell the tracking rebuild explicitly.

Best for: Shopify brands needing Shopping and Meta buying on top of a tracking setup that reports honestly. Limitation: despite the Riga registration, the three case studies they publish are British and international rather than Baltic.

6. Digital Ants — Czechia

Operating since 2012, with two published service lines and an unusually dense set of platform partnerships: Meta Business Partner, Google Partner, Mailchimp Partner and Hotjar Founding Partner.

Best for: Meta-led paid social with email attached. Limitation: the site publishes no dedicated analytics or measurement page, so the depth of the data work rests on the badges. They trade as Digital Ant on their own domain and Digital Ants on Clutch.

7. RAIBEC — Lithuania

The most complete consent-and-measurement stack of any Meta buyer here. GA4 implementation, Usercentrics consent-platform maintenance, privacy policy management and CRM data integration are all named as separate services next to the media buying.

Best for: advertisers who need the consent layer built properly, which in practice is most of them. Limitation: every testimonial published on the site is from a Lithuanian company, and the site was intermittently unreachable to automated readers.

8. Encore Media — Croatia

Paid media across Google, Meta, LinkedIn, TikTok, YouTube and Microsoft, with a fifth of declared work in business intelligence rather than campaign management. GA4 setup, Consent Mode and Looker Studio dashboards are named on their own site.

Best for: advertisers who want the tracking built by the team that buys the media. Limitation: no e-commerce specialisation is stated anywhere, and Clutch lists between two and nine employees, so capacity is small.

9. Dog and Pony — Hungary

The deepest verified review base of any Hungarian agency in this research, covering Facebook, Instagram, TikTok and YouTube advertising alongside Google Ads, creative and video production, and webshop development.

Best for: buying and creative production under one roof. Limitation: e-commerce is 5 percent of client work, the smallest share among the Hungarian agencies that publish one, and no analytics or CRM tooling is named on either source.

10. Sidera Digital — Slovakia

A strategy-led team publishing a dedicated Meta Ads offer next to Google Ads, LinkedIn, store development and conversion optimisation — and, unusually, naming the toolchain behind the analytics claim: GA4, Tag Manager, Looker Studio, Hotjar, HubSpot and Mailchimp among twelve platforms.

Best for: brands wanting the storefront and the media from one team, with the stack written down. Limitation: design and development together are the larger share of the work, so media is under half of what they do.

The layer under the campaigns, and who publishes anything about it

Read seventeen CEE agency websites in a row and a pattern appears that rankings usually skip. Nearly all of them describe channels. A minority name the measurement products they work in. Almost none say anything about what happens after the purchase.

Counting only what the pages state: RAIBEC names a consent platform and CRM integration, Sidera Digital lists twelve named tools, Encore Media names GA4 and Consent Mode, 94n Digital sells the tracking rebuild as a line item, Digital Ants carries four platform partnerships, and Amazonia PPC names Amazon Marketing Cloud. That is six agencies out of seventeen. The rest describe analytics in the abstract, or not at all.

On retention the count is one. Across the seventeen agencies on this list and its companion, 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 the gap above is real: an agency can optimise Meta perfectly and still not know which ad brought a customer worth keeping. 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.

The useful part for a buyer is narrower than a product pitch. Whichever agency you hire from this table, ask which numbers they will report on and where each number comes from. An agency that answers with a platform dashboard is telling you it measures the campaign. An agency that answers with your store revenue and your repeat rate is telling you it measures the business. Both are legitimate, they cost about the same, and they are not the same job.

How to choose a Meta Ads agency in CEE

Start with what they will optimise against. A good answer involves your margin: they ask what you make on a category, work out the return you need to break even, and set the target from there. A weak answer is a screenshot of platform return on ad spend.

Then check three things that are cheap to verify and expensive to discover late.

• Who owns the ad account and the pixel. If the agency owns them, leaving costs you your history. Put it in the contract.
• Whether they will touch the tracking. The Conversions API and consent handling are the difference between a campaign that can be optimised and one that cannot. If tracking is somebody else's job, ask whose.
• Where the creative comes from. Meta performance is largely a creative-volume problem now. An agency without production capacity depends on yours.

Two cautions from reading fifty agency sites for this piece. A profile with no reviews tells you nothing either way — good agencies often do not collect them. And a five-star average on four reviews is a far weaker signal than 4.8 on sixty.

Questions worth asking before you sign

• What will you optimise against in month one, and which number tells us it worked?
• Who owns the ad account, the pixel and the Conversions API connection when we part company?
• Which of our conversions do you expect to lose to consent refusals, and what is the plan?
• How many creative variants a month, produced by whom?
• Which named tools will you work in, and will we hold the logins?
• Describe an account 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 eighth, 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 Meta Ads market and the Polish e-commerce market. The companion piece here ranks e-commerce agencies across the same region, and both sit in our agency guides.

Which one fits you

If the storefront is your constraint, ExpandX and Sidera Digital build it and run the media on it. If creative volume is the constraint, Marketing Deck has the studio. If tracking is the constraint, RAIBEC and 94n Digital sell that work explicitly. If you are a midmarket retailer wanting one partner for everything paid, MTA Digital carries the largest e-commerce client share here. And if what you cannot see is what an acquired customer went on to spend, that is the gap the measurement section describes.
