The primary advantage of using a headless CMS is its flexibility in delivering content across multiple platforms without being tied to a specific presentation layer. This decoupled design allows developers to use various front-end technologies while accessing content through APIs. Consequently, businesses can create highly customizable and scalable digital experiences, improving performance and responsiveness. Additionally, a headless CMS enables seamless integration with omnichannel marketing strategies, as content can be distributed uniformly across various touchpoints.
