When people think about European retail media, they typically think UK, France, and Germany. But one of the most advanced retail media operations in Europe isn’t at Tesco or Carrefour — it’s at Allegro, the dominant Polish e-commerce marketplace that most Western European marketers have never encountered.
What Is Allegro?
Allegro is the largest e-commerce marketplace in Central and Eastern Europe. In Poland alone, it handles more online transactions than Amazon does in the UK. Its market position in Poland is analogous to Amazon’s in the US — dominant, deeply embedded in consumer shopping habits, and increasingly monetising that dominance through advertising. Allegro’s advertising business has been scaling rapidly, with advertising revenue as a percentage of GMV growing toward the range achieved by more mature Western European platforms. The company has invested heavily in self-serve advertising tools, audience data infrastructure, and measurement capabilities — giving it a retail media offering that competes credibly with much larger platforms.
Why It Matters for Global Brands
For consumer brands with significant Central and Eastern European exposure, Allegro is not optional — it’s the primary e-commerce channel in Poland, Czech Republic, Slovakia, and Hungary. Ignoring retail media on Allegro is equivalent to ignoring Amazon Advertising in the US. And the opportunity is attractively priced relative to Western European markets: CPMs and cost-per-click on Allegro’s platform are lower than equivalent networks, reflecting the earlier stage of market development. Early movers get access to audiences at costs that will rise as competition intensifies. Build the Allegro relationship now, before the rest of the industry arrives.
