Q: How do I stop my own team's visits from polluting GA4?
A: Two parts — define the traffic, then activate the filter:
— Admin → Data Streams → your stream → Configure tag settings → Define internal traffic → add your office/VPN IP ranges (this stamps traffic_type=internal).
— Admin → Data Settings → Data Filters → the 'Internal Traffic' filter sits in 'Testing' by default.
— Validate in DebugView: your hits show traffic_type: internal.
— Switch the filter from Testing to 'Active' — it's not excluding anything until you do.
TL;DR: Add your IPs under Define internal traffic, confirm the tag stamp, then flip the Data Filter from Testing to Active.
