Content strategy focuses on the planning, creation, delivery, and governance of content. Content not only includes the words on the page but also the images and multimedia that are used. Ensuring that you have useful and usable content, that is well structured, and easily found is vital to improving the user experience of a website.
The goal of content strategy is to create meaningful, cohesive, engaging, and sustainable content. Throughout her book, Content Strategy for the Web, Kristina Halvorson discusses in detail the benefits of and how to create your content strategy. It reiterates that your strategy helps you to identify what already exists, what should be created and, more importantly, why it should be created.
