WOM is the acronym for Word-Of-Mouth.
Word-Of-Mouth is when a consumer or business promotes another brand voluntarily in a one-to-one conversation or publicly via social media or another online site. WOM is consistently a leading driver of sales because its origin is from trusted resources that (typically) are not rewarded for spreading the word. As a strategy, there is also word-of-mouth marketing (WOMM), which encourages WOM.
