Extend Your Brand Into the Thriving Northern European Economy With Finland Advertising
Finland isn't often considered a priority advertising destination. Still, its position within the affluent, stable and highly skilled Scandinavian region, with a world-class infrastructure and business-friendly ecosystem, makes it a strategic location with excellent advantages.
The relatively small population of 5.6 million is augmented by over 22 million overnight stays a year, owing to the vibrant tourism sector. The country has a unique appeal as a place that attracts international visitors year-round, with the polar night and Northern Lights drawing audiences to the country in the winter.
Alongside neighbouring Sweden and Norway, Finland offers brand marketers a highly digitised media landscape where businesses can develop cross-border and high-impact campaigns, building on credibility and sustainability values relevant to Finnish audiences' buying decisions.
Why Advertise in Finland?
Finland’s outdoor advertising space has grown rapidly over recent years, expanding 8.7% yearly and forecast to hit £90 million in 2025. Further growth is anticipated at a pace of 19.17% between now and 2030. Coupled with the sharp increase in digital out-of-home marketing, Finland has been gaining traction as an affluent location for brands to be seen.
A large proportion of Finnish promotions are based in Helsinki, the capital. Helsinki is regarded as among the most innovative and stable cities in the world, attracting influxes of businesses, corporations, and start-ups, alongside the millions of tourists who head to Helsinki from around the world every year.
This provides an exciting proposition for brand marketers, who can engage with diverse and multinational audiences and target segments with high disposable incomes and education levels. They can also insert their brand messaging into a city known for its forward-thinking approach to innovation, with direct links to other regions as a gateway to Europe.

Frequently Asked Questions.
-
It’s always important to analyse who your customer is and which formats, styles and advertising positions are more likely to resonate, which is why there isn’t one perfect location we’d recommend for every billboard or every campaign.
For example, brands keen to expand awareness among older, educated audiences might opt for promotions around transport links to cultural sites like the Arktikum or the Seurasaari Ulkomuseo open-air museum, whereas those advertising summer activities and events might opt for advertising in the harbour town of Kuopio, which is famous for its summer festivities.
-
As we’ve mentioned, there are general rules that ban companies from erecting outdoor advertising immediately alongside the roads. However, this can depend on the situation and is primarily about protecting against traffic accidents rather than the advertising itself.
Most billboards will need a permit from the Centre for Economic Development, Transport and the Environment. Permissions depend on factors like environmental impact, local municipal regulations, and features of products linked to alcohol and tobacco, which are strictly prohibited.
