Decision tables

In SitecoreAI, component personalization uses a decision table to determine which version of a component a visitor sees.

A decision table is a set of rules that maps matching visitor conditions to a specific component variant.

Think of a decision table as a set of if this, then show that rules used to match visitors to different component variants. For example:

If this is true about the visitor	Then show this component
Visitor is a returning visitor	Personalized welcome banner
Visitor is using a mobile device	Mobile-optimized call to action (CTA) button
Visitor arrived from a marketing campaign	Campaign-specific promotional banner

When you personalize a component, you configure its decision table using three elements:

Input - the visitor data used for evaluation, such as country, device type, profile attributes, or custom values.
Rules - the conditions that determine when a visitor matches a specific scenario.
Output - the component variants and associated content shown when a rule is matched.

For example, when personalizing a hero banner component, you might configure the decision table to show localized mobile content to visitors in Denmark:

Input - country and device type.
Rule - If the visitor’s country is Denmark and they are using a mobile device.
Output - show the hero banner variant with the Denmark Mobile Promotion content.

Decision tables are evaluated from top to bottom, and the first matching rule determines which component variant is shown.

You can create as many rules as needed to support different personalization scenarios, from highly targeted experiences to broader fallback content.
