To effectively break through marketing noise and increase customer loyalty, marketers must prioritize personalization, transparency, and first-party data. Collecting and utilizing customers' interactions with their business, such as website or app data, provides valuable insights to create tailored experiences. However, building trust is also crucial, as only 65% of customers actually trust companies with their data, despite 95% believing they do. As the end of third-party cookies approaches by late 2023, marketers must adapt and rely on first-party data, focusing on transparency and customer-centric strategies to maintain loyalty and gain a competitive advantage.
