Data-driven personalization is the practice of delivering relevant content to your customers based on the information you've gathered about them. Before data and personalization, brands had to generate demand for their products or make assumptions about their audiences using generalized data. But thanks to the internet and mobile devices, it's possible to communicate with heightened awareness about your market.
A data-driven approach enables you to collect data and use that data for a better customer experience throughout the entire customer life cycle. More importantly, it allows you to communicate the right message at the right time, based on where the customer is in that cycle, increasing engagement and conversion rates.
But the secret to making this personalization work is trust, which is earned through responsibly managing your customers' data. You have to strike the right balance between data and personalization, and your customers' privacy.
