Frequently Asked Questions

Yes, when used as a compound modifier before a noun (e.g., 'word-of-mouth marketing'). It is not hyphenated when used as a noun phrase (e.g., 'spread by word of mouth').
'Buzz' is more intense, excited, and often media-driven or created around a specific launch. 'Word of mouth' is broader, more personal, and can be slow and steady. All buzz involves word of mouth, but not all word of mouth is buzzy.
