As marketers, it feels like we can never keep up with our customers. We may learn something about our audience or what resonates with them and by the time we've fully understood it and implemented it, they've changed. Changing behaviors can sometimes be frustrating. But that's life and digital marketing must keep up with changing customers and evolving market dynamics quickly. Luckily, marketers have access to marketing technology and tools that can help us adapt quickly and be more flexible.
