How? All those vars are tracking is campaign/traffic source, etc.
- jrockway 15y agoThe more information you have along with an HTTP request, the easier it is to identify the person that made that HTTP request. User-agent / IP / list of fonts that Flash can use pretty much identifies individuals uniquely. Adding "I got to this page by clicking a link on site X" to the URL adds one more piece of data that makes it even easier for the site to guess that you are you.
- staunch 15y agoWhy would a site need to rely on utm_* query params to identify you when they probably already have your IP/user agent/cookie session? Can you think of a practical way in which this would actually make a difference?
