Martin Moström is a strategic advisor with over 20 years of experience in shopper marketing. He founded Retail House and has authored several books on shopper marketing. Shopper marketing has evolved from separate functions like sales, branding, and trade marketing to a more holistic approach. It focuses on understanding shopper behavior by researching their shopping paths and the in-store stimuli that influence purchases. Effective shopper marketing strategies communicate value through visuals rather than words, help shoppers with relevant in-store information, and understand the retailer's perspective to support their category strategies.
