Clicks vs. Sessions

Clicks are recorded when a customer clicks out to your website, but please note that not every click results in a session.
Sessions last up to 30 minutes or until 12am, whichever is sooner. This means that if the same customer clicks out to your website multiple times within a 30 minute period, it will still be recorded as the same/one session.
You will find some documentation about clicks and sessions here
