Walmart is launching a "Back to School" campaign targeting 18-21 year olds and college students/fans. The campaign will run from June-September primarily on social media like Facebook, Twitter, and Instagram to promote discounted school supplies, furniture, and sports gear. The goal is to increase sales by 10% over the previous year through targeted digital ads and social promotions. Metrics like ad clicks, followers/likes, and sales will be used to measure the campaign's success.
