Sustained bestsellers are recommended.
And it makes all the difference.
In this book we mean “recommended” literally.When we say word of mouth (WOM) think only of honest, non- incentivized comments about either the product or the results the user got with it.
When people talk about a brand’s contest to win an iPad, or a funny viral video, they’re talking about the brand’s marketing, and that’s not the word of mouth we’re looking for.
