Targeting specific channel visitors, showing variation sitewide
I would like to target audience from a specific referral on my experiment.
The variation shows a change in the website's header, and therefore should be displayed also when the visitor browses different pages on my website.
Since the targeting rule states "behavior > referral URL", once the visitor browses to another page, that rule doesn't apply and the variation doesn't appear.
How can I solve this issue without involving my programmer?
