The work covers 34 Starwood properties in the UK, Ireland, France, the Netherlands and Scandanavia. Hotel brands included are Sheraton, Le Meridien and Westin.
DNA's parent company Avenue A/Razorfish is online agency of record for Starwood Hotels in North America and the two agencies will collaborate on developing global strategy for Starwood and tracking and analysis. However, the two accounts will be managed independently of each other.
Daniel Kerzner, Starwood's director of online marketing for north-west Europe, said: "This advantage will quickly position us at the cutting edge of search marketing in north-west Europe, benefiting all of our hotels and our customers. It makes sense to move our business to DNA so that one global organisation can handle our overarching strategy in this area."
DNA was acquired by Avenue A/Razorfish in December 2005. Its other clients include Mars, Pfizer and Weight Watchers.
