A unified brand experience means creating and maintaining a consistent identity throughout all channels where your brand has a presence. If your products are present in brick-and-mortar stores, online, and on social media, then you should make sure that you communicate the same message on all platforms.
When people interact with your brand, no matter the platform, they should feel the same, receive the same messages, and see the same products. If you don’t provide a unified brand experience, this will impact customer satisfaction and brand loyalty.
