# How to hide referrer
# How to hide traffic sources and show tracker's url as a referrer
If the traffic goes directly to the tracker, use these actions:
- Meta redirect (recommended)
- Double meta redirect
- JS redirect
- Open in frame
The campaign address will become a referrer.
If you integrate Keitaro through API, Script, Iframe or a Frameset use “Double Meta-redirect”.
# How to Send Blank Referrer?
Use this action “Blank Referrer redirect”.
# How to Send Custom Referrer?
Use an action “CURL”.
There are several notes about CURL's usage:
- A target website will not discover a real IP of a visitor
- Referrer can not be faked/substituted or hidden for external metric services, such as Google Analytics. They use a browser referrer.
