Zara's digital marketing strategy targets young people aged 18-40. While Zara has successful website and social media presences, the summary recommends that Zara increase its social media advertising spending from 0.3% to levels of competitors at 3-4%, and expand its social media platforms like Weibo and WeChat into other markets like China to reach more customers globally. Customer service also needs focus, as social media shows complaints about returns and delivery.
