Issue
There is a request sent to GA4 in the browser developer tools, but there is no data in GA4:
Reason
The reason is that the CMP（Consent Management Platform） configuration is wrong.
If the CMP is installed and it is not agreed by default, the user’s data cannot be tracked, so Google Analytics 4 has no data. You can see the gcs parameter in the request:
For example, G100 and G110 indicate that tracking is rejected. More are as follows:
| Value | Description |
|---|---|
G100 |
No consent has been granted. |
G110 |
Google Ads has consent, Google Analytics does not. |
G101 |
Google Analytics has consent, Google Ads does not. |
G111 |
Both Google Ads and Google Analytics have consent. |
Solution
Adjust CMP settings.
