Adding to that, always keep the user experience in mind. Reading, scrolling and clicking are tiring activities. So,:

1. Avoid unnecessary questions.
2. Use conditions to avoid asking questions not relevant for a specific participant.
3. Keep questions and answers short and easy to read - use appropriate markup.
4. Think about the trade-off between scrolling and clicking. Display everything on one page for short questionnaires (5-15 questions, depending on question complexity). Use groups wisely for longer questionnaires, i.e., group questions comprehensibly. Use group descriptions to give a clear statement about the topic of the following questions.
5. Avoid confusing participants with different scales, i.e., limit the amount of different scale types, scale scopes and different scale descriptions as much as possible. Try not to change the direction of scales. (There are some methodological exceptions).
6. For rating scales, it might be useful to use an even number of rating options to make decision making easier for the respondents (see below).
