I want to show a specific banner to anyone who visits our site with the following URL query parameter url.com?utm=golf
The issue I am facing is that I want to target them continuously with the same banner, unless they arrive again with a different UTM parameter. I believe if I build an audience based on Target> Audience> Entry page > parameter it is only going to last for one hit. Are profile scripts the best way to persist multiple sessions until the next UTM parameter?
Thanks in advance
