When Honest&Smile was appointed digital agency of EROSKI the brand was well established in TV, but had less than 3.000 likes in Facebook. We created a series of cross-media campaigns to dramatically boost their online presence, and the Facebook-based ‘Hide & Catch’ game was one of them. Prizes were hidden inside videos, websites or posts. But also inside real shops. Traffic was so massive that the whole system went down several times. But we ended up with +50.000 likes.
