Developing Retail Media Opportunities throughout Partnership

Retail media has the power to build brands and change shopper behaviour in store and online, but it is a complex beast for both retailers and brands. As retail media networks continue to gain traction, partners need to embrace the change journey to ensure growth and impact continues. But what does this mean in reality? During this opening discussion, our speakers will consider how retailers can captivate their audience by working with brands, leveraging partnerships and harnessing emerging opportunities beyond the digital shelf, off site and in store. We’ll hear how growth can be achieved through upper funnel activation strategies, and an integrated approach to create a more engaging and impactful experience with the customer.
