Let's say I have an inbound link on a partner site. A visitor clicks on the link, which is then supposed to open a new window displaying my site. However, the visitor has a pop-up blocker installed and the window does not open. Will this still count as a referral from the partner site if I'm using client-side tagging to collect data? I wasn't sure if the browser is still able to communicate with the server on some level. Thanks!
