Multilingual survey best practices
You can create surveys in multiple languages. Depending on your distribution channel, email invitations will be sent in the contact's own language or you'll get a survey URL per language.
Start with one language
When you create your survey, select only one language to begin with. Add all questions, branching, and display logic. Make sure the questions are correctly phrased and all of the necessary answer options are mentioned. Then test thoroughly before adding the other languages.
Use the translation file
Once the survey is completely ready in one language, use the translation file to add the translations. First, add all of the other languages in which you you want to distribute the survey. This way, all of the necessary language codes will have been added automatically.
Use the same response order
When creating multilingual surveys, make sure that all responses are in exactly the same order in all languages.
If you're worried about the answer options not showing up in the correct order in a certain language, you can set the response order to alphabetically. This way, all options will be alphabetical in each language. Or set them to randomly to exclude bias. The default response order shows the response options in the exact same order as they are listed in your question.
Translate the emails
You have already translated all survey questions and survey pages using the translation file, but when sending emails via Agile Research, you must also translate the invitations and reminders.
By adding the correct language code when importing contacts, each contact will receive their invitation in the correct language.
Test your surveys
Plan enough time to complete testing in all languages. Test your survey, send preview mails, add test contacts, and use their preview link. There are various options to test your surveys. Depending on how you distribute your surveys, one may be more fitting than the other. See Test your survey for additional information.
Analyze per language
When sending multilingual surveys, reports will show the answers for all respondents by default. In some cases, it is more important to know how a specific language segment responded. In that case, filter on a particular language group.
Download reports in different languages
By default, reports will be shown in the default survey language. But with doing multilingual surveys, you can download the report in all available survey languages.
You can find the list of languages in the upper-right corner. Select the desired language and the report will reload in that language. All downloaded reports will respect the chosen language.
