Hotels.com has over 100 branded points of sale in over 60 countries; with a proven platform in multiple languages, the affiliate program is a natural avenue to accelerate growth in established markets and help venture into new ones, whilst maintaining a strong ROI. In 2011 Tradedoubler facilitated programs in 15 European markets; by the beginning of 2013 this has expanded to over 25 markets including Latin America, Brazil, and Eastern Europe. Tradedoubler also supported Hotels.com launch one of the first successful multi-market mobile and app affiliate programs; unique tracking, willingness to trial new partners, affiliate platforms, bespoke mobile creative, and remuneration outside of pure CPA have contributed to the overall results. All of this has been achieved whilst Hotels.com initiated a new brand identity across all markets, introduced new forward planning strategies, and approach to diversifying the affiliate channel outside of exclusive CPA models. Our case study will offer insight into how Hotels.com and Tradedoubler worked collectively to utilise technology, key travel trends and multiple performance channels to deliver an award winning affiliate programme
