How to Set Up Filters in Google Analytics 4?

[shukla7789]

A filter in Google Analytics 4 (GA4) is a tool that allows you to automatically filter incoming data by a certain parameter. It is very important to set filters up correctly because they exclude the actions of the team working on the project from analytics and allow you to analyze what real users have done.

What are the types of data filters?
Currently, there are two types of data filters in GA4:

Internal traffic filters are used to exclude portugal number dataset traffic.
Developer traffic filters are used to exclude traffic coming from debugging devices.
Let's look at both types in detail.



What is an internal traffic filter in GA4?
Internal traffic is generated when copywriters, suppliers, managers, SEO specialists, etc., visit the site. These users are not the target audience, but if the team is large, the traffic volume will be significant and distort the data in the reports. An internal traffic filter will exclude them.

What is a developer traffic data filter in GA4?
Developer traffic comes from users setting up or tracking a resource in debug mode. It allows you to check if site settings are working correctly.

However, it also affects the indicators in reports, so it should be filtered. Using this filter, such data will remain only in the DebugView report, which is necessary for testing and allows you to check each change before deploying it in the working environment.

Filter modes in GA4
Filters can be in one of three modes: testing, active, or inactive.



Testing mode
It is crucial to test filters before activating them as they will irreversibly change the information. Once you cut off certain data, you will no longer see it in Analytics.

However, a filter in testing mode does not make irreversible changes, and you can analyze its performance. To do this, add a comparison to the report using the Test data filter name parameter.



Active mode
In this mode, the filter irreversibly changes the data. Click the three-dot options menu (1) > Activate filter (2) to activate it.
