Context Expression
Context Expression enables you to use JEXL context expressions to define Target Groups for personalized web content.
The Context Expression feature Tridion Sites is part of the profiling and personalization feature set in Tridion Sites. Profiling is used to track who visits your website—the content they access and the links they click—while personalization enables you to define types of website visitors and to mark content as being only relevant to a specific type of visitor.
The context expressions themselves are supplied by integration with a separately-installed Context Expression Module, which requires implementation of Digital Experience Accelerator (DXA). The following diagram illustrates the architecture of the extension and DXA module within the Tridion Sites environment:
