Tradedoubler is one of Europe's longest-standing affiliate networks, founded in 1999 in Sweden. The platform connects affiliates with a wide range of advertisers primarily across European markets, making it particularly valuable for publishers with EU-focused traffic. Tradedoubler offers a clean interface with decent tracking technology and real-time reporting capabilities. Their advertiser portfolio includes well-known European brands spanning retail, travel, finance, and telecom verticals. The network's strength lies in its deep European market penetration and established relationships with premium advertisers that may not be available on other networks. However, there are notable drawbacks: payment thresholds can be relatively high, and the platform feels somewhat dated compared to more modern competitors like Awin or CJ Affiliate. Affiliate support quality varies, and approval times for some programs can be slow. North American publishers may find the advertiser selection limited. Best suited for experienced affiliates targeting European audiences who want access to region-specific offers not found elsewhere.
