On May 14, 2023, the “Landing page” dimension in Google Analytics 4 will stop returning query strings included in the URL. For example, if the dimension returned /blog?search=term before the change, after the change, it will only return /blog.
What you need to do
To get the query string, you can use the new "Landing page + query string" dimension. However, this dimension is only compatible with a limited number of other fields. See the full list below.
Full page URL
Page path, query string, and screen class
Total user engagement duration (sec)
Note also that according to Google, the current "Landing page" dimension will be deprecated in the future. When this happens, we'll make sure your queries continue running with minimal disturbance.
