Social Traffic
BeginnerSocial traffic is the set of visits whose referring domain belongs to a social network or messaging app, or whose campaign tags declare a social medium.
The classification is a simple lookup: the tool compares the referring domain against a list of known social domains that it maintains itself, so two tools can disagree about the same visit and one may count a messenger as social while another calls it referral. The larger problem is dark social, since most real sharing happens by pasting a link into a private message and that visit arrives with no referrer header and settles in Direct, which makes the reported figure a floor rather than the true amount. In-app browsers shift the numbers further, because their separate local storage causes the same returning reader to be recorded as a new user. The only reliable way to close the gap is to tag every link the team publishes with UTM parameters.
