GTM Regex Best Practices
- Use exact match for specific page paths, IDs, and event names.
- Use one value per line to keep your source list easy to review.
- Test sample values before publishing your GTM container.
- Use “contains” carefully because it can match unintended values.
- Keep regex rules documented in your GTM naming convention.
