Dark Social
Traffic and sharing that happens through private channels (DMs, email, WhatsApp) that can't be tracked by analytics tools.
Dark social refers to content sharing that occurs in private or encrypted channels — direct messages, email, SMS, WhatsApp, Slack — where standard analytics tools can't track the source of the traffic. When someone copies a URL and shares it in a text message, the resulting web traffic typically shows up as "direct" in analytics.
Research suggests that the majority of social sharing actually happens through dark social channels, not on public feeds. This means most analytics significantly undercount the true viral spread of content.
For marketers, dark social is important to understand because it means your content's true impact is likely greater than your public metrics suggest. UTM parameters and branded short links can help capture some dark social attribution.

Frequently Asked Questions
- How do I measure dark social?
- You can't measure it perfectly, but you can reduce undercount by using UTM parameters on all shared links, tracking direct traffic separately, and using surveys ("how did you hear about us?"). Some tools like Oribi and HockeyStack have better dark social attribution models.
