Data-driven marketing leverages insights from customer behavior, preferences, and trends through data collection and analysis to enhance marketing effectiveness and personalization. In comparison to traditional marketing, which relies on past experiences and limited data, data-driven strategies utilize digital technologies, allowing for real-time adjustments and improved targeting. Nike exemplifies successful data-driven marketing by segmenting its audience demographically and behaviorally, utilizing personalized campaigns, and adapting strategies based on local trends, leading to significant revenue growth.
