Ask How can a brand keep its tone the same when many people write its posts?

[Newman]

Keeping one tone across many writers is quite hard, but it becomes easier when a brand creates very clear writing guidelines that explain how to sound friendly, formal, or playful. Sharing examples of good and bad posts helps writers understand the exact tone expected of them. Some brands even create a simple style document that lists words to avoid and phrases that fit their voice best. What method works best for keeping a brand tone consistent across different writers?
