The successfulness of content relies on the usability and user experience of it
People like looking at content that is easy to follow and useful to them. We improve elements within our content to make it “user-friendly,” such as writing, typography, visuals and other details. We also do this so our content is more helpful to our audiences. Visual content is heavily focused on this idea, to increase the user experience and usability of the content it is presenting. The Functional Art, Usability Geek and Interaction Design discuss and showcase content that carters to these ideas.
