Clear writing allows your words to mean exactly what you want them to without leaving room for misinterpretation. Clear messages prevent confusion, mistakes, and wasted time. Clarity in writing requires you to have an understanding of who exactly you’re writing for, as the needs of a lay audience will significantly differ from a message directed towards, for example, other engineers working within your field.
Well presented content creates engagement, making you a more enjoyable read for your audience, more relevant in your field and ultimately giving you more influence.
