Millennials are using social media and YouTube to decide what to buy. A U.K. study found 32% of 18-24-year-olds are using social media to research their purchase decisions before checking out, and 25% are using video platforms like YouTube. There are also signs they’d like to search for products on social media: 25% of U.K. 18-24-year-olds reported the desire to search media based on their lifestyle and 23% would like search to understand their current mood. These findings, paired with the detailed targeting available to advertisers, are changing the consumer journey from search query to cart. (AdvertisingWeek)
