Luxembourg's digital advertising market continues to grow steadily, with a projected spend of €315 million in 2026. The ad fraud rate remains relatively low at 4.2%, thanks to advanced detection technologies. Mobile advertising accounts for over 60% of total ad revenue, reflecting the country's high mobile device penetration and digital engagement.
Despite the robust growth, advertisers must remain vigilant against ad fraud, which can undermine campaign effectiveness. The high CTR of 1.75% indicates healthy engagement levels, but ongoing investment in fraud prevention is essential to sustain market trust and ensure optimal ROI for brands operating in Luxembourg.
