Using Stack Rank allows you to ask your audience to rank a list of items according to their preference.
Add Stack Rank
To add a Stack Rank element, go to 'Add Elements' in the builder.
Choose 'Stack Rank' under the Response Types section. Clicking this button adds one Stack Rank element to the screen.
Configure Stack Rank
To add or remove choices, select a currently displayed choice or button. Click the appropriate action (Add or Remove) in the toolbar that appears.
To reorder options, use the functionality provided in the toolbar. Remember that the order choices appear in the editor is the order the end user will see them initially.
To design the style of your Stack Rank buttons, use the styling controls in the left hand panel. You can change elements like color, fonts, and size.
Ensure you include clear instructions for the end user. Tell them exactly what you want them to do, for example, "rank your favorite colors".
End User Interaction
From the end user side, they can pick items up and put them down to arrange them. A pre-clean animation ensures items shift automatically, so users are not confused about the position of each item.
The Stack Rank tool is ADA compliant. If an end user cannot drag and drop using a mouse, they can take advantage of a dropdown menu using only their keyboard functionality.
After arranging the items in their preferred order, the end user clicks submit.
Incorporating Stack Rank into Logic
Outcome Logic
Each response choice has an associated amount of positions (e.g., four positions for four choices). These numbers represent where someone from your audience has ranked that specific response. If a high ranking is correlated with a certain product or outcome, you should score that ranking highly under the appropriate outcome. For example, if an end user ranks "Brown" first, you might give 5 points toward a "Brown Glasses" outcome; if they rank it second, you might give 3 points.
Dynamic Product Feed Logic
Each response choice has an associated amount of positions. You find the relevant column header in your product feed, such as "color" or "material". If a high ranking correlates with a certain product category, you should map the characteristic of that category on the same line as the position value. For example, if an end user ranks "Purple" first or second, you can map that to include purple products. It is up to you whether you associate a specific rank (like second) with a characteristic. If a user ranks an item last, you probably do not want to associate that quality with the product. If a user picks a characteristic (like "black") first or second, the logic includes all black product frames as possible recommendations, depending on how they answer the rest of their questions.

FAQ
How will Stack Rank responses look in the reporting dashboard?
In the reporting dashboard, Stack Rank analytics show the average position for each choice presented. The average position is calculated by taking the sum of all individual positions for a choice and dividing by the total number of times that question received submissions.
The average position provides an understanding of where items are ranked on average across all responses. Lower average position numbers mean the choice was ranked highly on average. Items ranked more towards the bottom have higher average position numbers. Items with lower average position numbers are generally more valuable on the aggregate level to your customers.
