Learn how to configure GTM triggers that fire based on event variables and pass relevant data to analytics platforms. Understand the importance of using consistent and well-defined event naming conventions to ensure accurate data reporting.

User-Defined Variables

• Data layer variables: Extract data from the data layer using GTM's data layer variable type. Learn how to configure data layer variables to capture custom parameters, user IDs, and other relevant data. Understand the importance of using data layer variables to track user behavior and personalize website experiences.
• JavaScript variables: Implement custom JavaScript variables to extract data from the page or perform complex calculations. Learn how to write JavaScript code that retrieves data from the DOM, sets cookies, or performs mathematical operations. Understand the security implications of using custom JavaScript variables and how to mitigate potential risks.
• Lookup table variables: Use lookup table variables to map values from one variable to another. Learn how to configure lookup tables to translate user input, categorize data, or personalize website content. Understand the benefits of using lookup tables for data standardization and data transformation.
• RegEx Table variables: Use RegEx Table variables to match and replace regular expressions and transform one value to another based on regular expression patterns.

Advanced Triggers and Event Tracking
