4. What is a data layer in Tealium iQ?

The data layer is a structured collection of variables that captures user, page, and event-level data. Tealium iQ uses the Universal Data Object (UDO) to store and pass data consistently to all integrated marketing and analytics tools.

5. What is the Universal Data Object (UDO)?

The UDO is a JavaScript object that holds key-value pairs representing user behavior and page information. It ensures standardized data collection and reduces discrepancies across multiple vendor tags.

Extensions are custom logic components that allow users to manipulate data, set variables, and control tag behavior without writing custom JavaScript. Extensions can be scoped globally, per tag, or per load rule.

Load rules define when and where a tag should fire. They evaluate conditions such as page name, event type, or user attributes to control tag execution.
