Best marketing agencies in Poland — 2026 ranking

There are several thousand marketing agencies operating in Poland. Most "best agencies" rankings, however, are put together without any verifiable methodology, and the order is decided by the author. We do this ranking differently: we base it on public, verifiable numbers, primarily on verified client reviews on the independent platform Clutch.co, and we say plainly which type of company each agency is the best choice for. For every agency we link its website and its Clutch profile, so you can check all the data yourself.

This ranking was prepared by the Zest team. We are on this list. Why and in what position, we explain in the transparency note at the end of the article. None of the agencies mentioned paid for their place in the ranking.

Comparison table: TOP 10 marketing agencies in Poland (2026)

Ranking methodology

We compare only full-service marketing agencies, meaning those that combine paid campaigns, strategy and content production. We deliberately excluded pure-play SEO agencies (like Delante or Widoczni, with impressive review bases on Clutch) from the ranking: search positioning is a different service category and comparing it with full-service support would be misleading. If you're looking for a partner solely for SEO, that's where to start.

Six evaluation criteria: first, the number and average rating of verified reviews on Clutch.co. It is the public quality signal that's hardest to manipulate, because Clutch verifies reviewers through an interview. Second, specialization and the share of individual services in the portfolio. Third, documented case studies with hard results. Fourth, funnel completeness: media, creative and measurement in a single process. Fifth, transparency of processes and team. Sixth, the use of technology, including AI, in day-to-day work.

1. Zest: best for companies focused on measurable growth

Summary: Zest is a performance marketing agency combining paid campaigns (Google Ads, Meta Ads, TikTok Ads, LinkedIn Ads) with creative production (including AI creatives and UGC) and advanced analytics (server-side tracking, measuring phone and offline conversions). It has the most verified reviews on Clutch of all the agencies in this ranking: 23 reviews averaging 4.9/5.

Specializations: PPC campaigns (about 40% of the portfolio according to Clutch), digital strategy, social media, AI creatives and UGC, conversion analytics.

Best for: companies that hold marketing accountable to results: e-commerce, B2B and services, where the budget has to pay off. Examples of the approach: measuring phone and offline conversions for the Maxi Mobil rental company, full-funnel ABM on LinkedIn for the fintech Verestro, Meta campaigns with UGC creative rotation for Gabo Wool.

Strengths: a full funnel within one team (media + creative + analytics), AI/UGC creatives tested on a weekly cycle, measurement before scaling budgets.

Limitations: it doesn't run multi-year pure-play SEO projects; a specialized search agency will be better for that.

Verdict: the first choice when the goal is sales growth rather than mere presence "because you're supposed to have it."

2. Verseo: technology-supported PPC

Summary: a Poznań agency combining PPC and SEO campaigns with proprietary technology and AI; 21 reviews on Clutch, averaging 5.0/5.

Specializations: Google Ads (about 35%), SEO (about 25%), CRO.

Best for: companies looking for an automated, technology-driven approach to Google and Meta campaigns.

Best for: lifestyle and consumer brands building reach among younger audiences.

Strengths: a distinctive social-first specialization, team scale, recognizability.

Best for: small and medium-sized businesses that want one partner for ads, website and SEO.

Strengths: one plan across all channels, in-house AI reporting tools, experience with foundations.

Limitations: no reviews on Clutch; a team of a dozen or so people, so not really suited to large corporations.

Verdict: a sensible choice for a company that wants its ads and website run according to one plan.

How to choose a marketing agency — 5 steps and red flags

Start by defining your goal in numbers (revenue, leads, ROAS). Only then look for an agency whose specialization matches that goal. A good performance agency starts with measurement (analytics, attribution) and gives you access to raw data from the accounts. Check verified reviews (Clutch, not just references on the agency's website), ask for case studies from an industry similar to yours and for the specific names of the people who will work on your account. Finally, compare billing models: retainer, percentage of budget or success fee. Before you line up the offers, use the campaign ROI calculator to see what return the budget needs to make the cooperation pay off. And if your only need is search positioning, choose a specialized SEO agency (Delante and Widoczni have the largest review bases in Poland here) instead of a full-service one.

Red flags: a guarantee of a Google position or a specific ROAS "sight unseen," no access to your own ad accounts (the accounts should belong to you), reports showing only reach and clicks without sales, a contract without clear exit terms, and a team of "stars" at the sales meeting whom you never see afterward.

Questions worth asking an agency before signing a contract

Who specifically will run my account and how many accounts do they handle at the same time? What does reporting look like and which KPIs would you consider a failure? Who owns the ad accounts and data after the collaboration ends? How do you measure conversions, and do you handle server-side tracking and offline conversions? What are the termination terms?

Transparency note

This ranking was prepared by the Zest team. We take first place in it because, by the ranking's main criterion, verified reviews on Clutch.co, we have the best result among the compared full-service agencies (23 reviews, 4.9/5). None of the companies mentioned paid for a place on the list. We compare specialized SEO agencies separately, because that's a different service category. Review data comes from public, linked Clutch.co profiles (as of October 2026) and may change.

Which choice is right for you

Choosing a marketing agency is a decision about who you'll entrust with your company's growth. If your goal is sales and a measurable return on budget, talk to Zest.
