The referrer property on the session should show where the visitor came from. Eg. someone clicked a link on twitter to my-landing-page.com then referrer is twitter.com But what if someone currently has twitter open - and he types in my-landing-page.com Will the web session of this visitor still list twitter.com in the referrer property? Motivation behind this question: My lp can focus on telling a visitor what the product does …or - knowing the visitor has already had an explanation, eg. from a friend who then told him to visit my-landing-page.com - focus more on why the product is important. (And for those of you who tell me to start with the why - I know from my own experience that people don’t have enough patience for the “why”, when the “What is it?” question isn’t answered quickly) If a visitor comes from any domain, (unless I know it’s from a particular article/post/video where the product is being explained) - which would mean that the referrer property is empty - I would show them a version of my lp that is overly clear in the hero section on what is being offered.

No, definitely won't show as referrer. In GA or any other attribution tool an entry of a URL in the browser would show as source=direct
