What is the Traffic Source feature?
Web analytics services such as Google Analytics track the traffic source of your visitors. You can choose between direct, referral, organic search, and social traffic sources when you submit your website.
If you want entirely anonymous traffic, choose the direct traffic source. Google Analytics will show such hits as direct hits.
If you want the traffic to come from a specific URL (e.g., https://imgur.com), choose the referral traffic source. Google Analytics will show such hits in the referral channel from the URL you specify.
For organic search, you can enter one keyword from where you want to receive the traffic, and social traffic source allows you to select one from the dropdown. Traffic from those sources will show up in organic search or social channels, respectively.
If you want traffic from different URLs, keywords, or social networks, submit your website multiple times, each with a different one.
In case you are unsure, selecting a direct traffic source is always a good choice.
