About and context

We've been working with Decathlon, with the support of their agency "Les causantes", since 2021, first on their in-store traffic acquisition strategy, then to their site, with targets ramping up over the years.

Against this backdrop of strong brand awareness and already massive traffic, the challenge lies in continuing to attract truly relevant visitors, without saturating channels or degrading the deliverability of campaigns.
