A GA4 property sits under an account and is an analysis space where data is collected and analyzed. In Universal Analytics, properties corresponded one by one to a single platform (web or app), but in GA4, web, iOS, and Android streams can be attached to one property for integrated analysis of cross-platform data.
The GA4 hierarchy is ‘Organization → Account → Property → Data Stream’. In practice, it is common to create accounts on a corporate/brand basis and properties on a service/domain basis. For example, if one hospital corporation operates three sites, three properties are created for one account.
Key settings such as data retention period, data filters, BigQuery connection, and Google Ads connection are made at the property level. Permission management is also done on a per-property basis, so when sharing only specific site data with a client, permission is granted only to that property, not to the account.
Key takeaways
- Located under Account, it is an analysis unit that unites web, iOS, and Android streams.
- Unlike UA (Universal Analytics), multi-platform integrated analysis is possible in one property.
- Core settings such as data retention, data filters, and BigQuery connections are managed at the property level.
- User permissions can be granted to each account and property, and granting permissions per property is safer in practice.
- Up to 2,000 properties can be created in one account.
