| Dimension | Default / Custom | Scope |
| Landing page + query string | Google Analytics Default Dimension | Session-scoped |
| full_url_for_landing_page | Custom Dimension | Event-scoped |
As shown in the table above, Landing page + query string is a default dimension of GA, and full_url_for_landing_page is a custom dimension created as needed.
In the case of Landing page + query string, the query should be collected by default, and it is normal for it to be collected with a value such as full_url_for_landing_page, but there are cases where the query is not included properly due to an error in the current processing of GA4.
Accordingly, we were using full_url_for_landing_page as a custom parameter to prepare for cases where data is missing from the default dimensions and to store campaign data values based on the landing page.
However, since full_url and full_url_for_landing_page currently need to be modified to improve consistency, we recommend the following method for landing page analysis.
