The biggest challenge is to use very few words in a limited space with a well-defined goal.In UX writing, one should always be aware that expressions and phrases that people use can often turn out to be very subjective. This might be related to regional origin, a certain level of knowledge (e.g. specific expertise) or even socio-demographic background.That is why UX professionals like to do user tests – as the insights from testings enter the subsequent text creation. Well-known qualitative testing methods are, for example, card sorting or tree testing. It is also advisable to create a tonality map before the actual creation of the microcopy. As already mentioned above, different contexts of use are labelled with an appropriate and individual tonality. This assignment works e.g. in the form of a grid or along predefined touchpoints of a user journey.
