UX writing is the text on an interface that guides users through your product—you know, buttons, instructional text, error messages, etc. If you think about a product you use and enjoy frequently, the UX writing is probably strong, even if you’ve never noticed it before. And if you think about the products you’ve hated, there’s a good chance that weak UX writing was a culprit of your painful experience.
UX writing is a pretty new discipline within content strategy (which is a relatively new discipline within UX). But since product teams don’t often have the resources for a dedicated UX writer (or content strategist), the responsibility often falls on product owners, developers, or designers.
What’s the difference between marketing copy and UX writing? Marketing copy (or copywriting) is about attracting eyeballs and selling a product. If you find yourself doing writing for UX, however, your focus doesn’t need to be on selling your product because your users are already using it! Save the sexy words, sales pitches, and gimmicky phrasing and stick to simple on your interfaces.
