Writing copy for international audiences is notoriously tough. Whether you’re creating web copy, marketing content, or interface language, how do you make sure your brand voice shines through in 12 languages? Wording that seems friendly and approachable in English might be totally inappropriate in German or Japanese.

Even if your copy will never be translated, you still need to think about global audiences who may have different cultural contexts and varying levels of proficiency with English. And if you deal with financial data, privacy, or any number of other sensitive topics, the consequences of getting it wrong can be catastrophic. Global B2B brands like Cisco, Tendo’s long-time client, already understand the importance of accuracy and cultural context in translating technical information. Does your company?

Luckily, the content strategy community is here to help. I recently attended a panel on this topic, hosted by the San Francisco UX Writers Meetup at Flexport’s San Francisco HQ. Although the event focused on UX and interface writing, the advice shared applies to any kind of writing, from website content to email marketing copy.

Andrea Niederkofler from the Product Localization team at Zendesk, Sylvie Kim from the Content Design team at Slack, and Sara Getz from the Content Strategy team at Facebook spoke at the event, and all three shared valuable insights about writing for translation, building localization into your content creation process, and understanding your users’ context. Here are five key takeaways.

Key #1: Collaborate and Communicate

Involve your translation or localization team early in the process, before you start writing copy. They’re the experts, and they can give you invaluable tips for writing copy that’s easy to localize, as well as insights about your international customers. Build this communication into your writing process so they can help your brand voice shine through.

Key #2: Provide Context

Without appropriate context, your translators may produce inadequate content through no fault of their own. Keep a detailed style guide, and make sure it’s available to your translators. Glossaries of industry- or client-specific terms are also useful, as are any supporting documents. And the shorter your copy, the more crucial the context—so when you’re writing things like labels and interface copy, Andrea Niederkofler suggests that you include as many grammatical details as you can. Mark what as read? How many are visible? Is “Search” a noun or a verb? Translators may need to know all this in order to produce good localized content.

Key #3: Don’t Assume

Don’t assume that grammatical structures will be the same. That idioms will translate. That copy will be the same length in translation. Or anything, really.

Key #4: Have Empathy for Your User

Your users may not be approaching a situation or topic with the same mental model you’re using, and it’s important to understand where they’re coming from. This is true of any writing: How many times have you been told to know your audience? But it’s even more important when you’re writing across language and culture.

Sara Getz brought this lesson home by recounting how she and her team tested a new feature with female users in India, and had to factor in key aspects of their context: These users frequently use English online even though it may not be their native language; they are often using mobile devices with small screens and keypad navigation; and they may have only gotten online for the first time within the last few years. In a world where businesses have global reach, you can no longer afford to assume that your users are exactly like you.

Key #5: It’s OK to Break the Rules

Sylvie Kim says that her team doesn’t always follow generally accepted localization best practices. In particular, although many experts say to avoid idioms in writing destined for translation, the Slack brand is well known for its casual, idiomatic voice. Instead of limiting themselves to a formal and uninspired writing style, the content design team at Slack has built a close partnership with the localization team, which allows them to communicate the intent of their words and make sure that the brand voice comes through in each of the six languages Slack supports.

As with all things content related, writing for translation is much more complicated than it looks at first glance, and you shouldn’t wing it. With these tips and best practices, you can make sure your content resonates with global audiences and help ensure that your brand’s entry into global markets doesn’t fall flat.
