Companies of all sizes today are looking to improve the effectiveness of their social media marketing — and with good reason: Digital platforms are constantly innovating the way that brands are discovered, shared and experienced. The data speaks for itself: The number of worldwide social network users is expected to reach 3.09 billion monthly active users by 2021, and global internet users spend some 136 minutes per day surfing social networks. Many organizations have responded by allocating more resources to digital marketing — technology now accounts for 29% of total marketing expense budgets, according to a recent Gartner estimate, and digital ad spend for 2020 is estimated at about $385 billion.
