Nice one, thank you! This is incredibly relevant for me.

[@JordySlinkman]

Nice video!
Maby it's also useful to mention the quotum GA4 (currently) has on the amount of custom dimensions you can make.
User based: max 25.
Event based: max 50.
Item based: max 10.

How to export all pages by status from google console? For example, Crawled - currently not indexed. Can LookerStudio or PowerBI do it?

Hello Julius, it would be great if you coul'd do a video about reports of steps and events of a chatbot + if we have different funnels as ab tests how to track them, thanks for the good work !

[@mayanksharma5226]

Very well explained. One query I have, I am trying to export data from GA4 to BigQuery, There I dont see these custom dimension getting exporting. Is there any restrictions regarding that?

[@PedroSavi-vq9og]

Hi, in your case, you are sending the response (in array objects) in the dataLayer. How can I see the values in the free form?

[@omarjamil5688]

If I register parameters as Custom Metrics and Custom Dimensions in Google Analytics 4 but don't include them in any reports at the time, will GA4 still collect and save historical data for these metrics and dimensions from the moment they are registered, allowing me to use them for analysis in future reports?

[@isosquare2812]

Very nicely done! Could you elaborate on how an event settings variable is better suited for tracking user-scoped dimensions? Wouldn't a user-scoped dimension hold its initial value indefinitely after being passed as an event parameter once?

What is user propertybecomes available onky after the google tag has already fired?

[@ramond5689]

everytime i want to save something in gtm there is an error and it said: invalid input. you may have old data. which is weird because the account only exists 2 months. can someone explain to me how i can solve the problem. i would be really happy!

How accurate is GA4 data?
Can it track if a person clears all browser cookies?

[@damadorpl]

GA is for tracing events and taht happen on your site

[@pushkardua]

GA4 tracks using the tag fired on your website. If someone removes all the cookies, they would be considered as a new user (considering you are not collecting user IDs). If you are collecting user id, they would be tracked as the same user once they log in and they user id is sent to GA4
