Spain's affiliate marketing sector is experiencing rapid growth in 2026, with revenue reaching €2.1 billion. The digital ecosystem is maturing, encouraging more brands and affiliates to collaborate. However, the sector faces challenges such as a fraud rate of 3.8%, which impacts trust and profitability. Continuous investment in fraud detection tools is helping to mitigate these risks and enhance overall campaign effectiveness.
The increasing number of active affiliates, now estimated at 150,000, reflects the sector's expansion. The average commission rate of 8.5% indicates healthy earnings for marketers. As digital ad spend through affiliate channels rises to €1.3 billion, Spain's online economy is set to become more competitive, emphasizing the need for robust fraud prevention measures and transparent practices to sustain growth.
