3. Leading Indicator: Positive tokens with small occurrences should be explored further

This is the “Art” of the analysis. These are guidelines but not rules. These datasets open the door for great exploration.

“Quality” Doesn’t Instill Confidence

“Fresh” is a descriptive explanation of why the product is high quality

Flowers Are “In The Moment”

Same day shipping is important to flower buyers as they are consistently an “in the moment” purchase for someone special or to react to an event

Use Emotional Action Statements

“Show” is an emotional action statement highlighting the benefit to the flower purchaser

“Choose” is a process oriented action, describing the buying action and not the recipient's reaction
