The firm parts ways with Brands2Life, which previously handled the UK component of the business. The EMEA brief is a newly created assignment.
In addition, Kelkoo has reappointed Hopscotch to handle its business in France.
The decisions follow a lengthy pitch process that was overseen by Kelkoo PR director Cristina Rebollo. The final round involved four agencies, with Red emerging successful.
Red's task is to reposition Kelkoo as a leader in European online shopping. Currently, Kelkoo ranks third in terms of European users and has invested in building up its marketing and PR operations since Yahoo offloaded it in 2008.
'Red broke new ground with its first pitch, then adapted its approach in the second stage through new creative routes. These will help us challenge established brand leaders and raise our awareness across our European markets, as well as the UK,' said Rebollo.
Red MD Andrew Baiden led the agency's pitch team and will take overall responsibility for the account. Red consumer brands director Matt Buchanan will oversee strategic planning, while associate directors Andrea Carter and Ben Dutton will run Europe and the UK, respectively.
The two accounts include corporate, broadcast and digital integration.
