GA4 custom dimensions allow you to import data beyond the standard metrics Google Analytics 4 collects, giving you a far more personalised and insightful view of your Australian customer base. Essentially, they let you categorise your users and events with information specific to *your* business.
- User-scoped dimensions: These apply to individual users – think membership level, postcode, or industry.
- Event-scoped dimensions: These relate to specific actions users take, like product category purchased, promotion code used, or the specific branch of your business they interacted with.
- Item-scoped dimensions: Now features enhanced e-commerce tracking, allowing detailed analysis of product attributes like colour, size, or material.
As of early 2026, current systems include robust integration with Customer Data Platforms (CDPs) and Australian CRM solutions like Zoho and HubSpot, making data transfer seamless. This is particularly important for Australian businesses needing to comply with evolving privacy regulations; custom dimensions allow for granular data control and anonymisation where required. Furthermore, GA4 in 2026 automatically handles data residency concerns for Australian users, ensuring compliance with local data storage laws.
