Dark social

Dark social is the sharing and discussion of content in channels analytics cannot observe: private Slack and WhatsApp groups, DMs, forwarded emails, word of mouth. The influence is real but arrives untagged, typically surfacing later as 'direct' traffic or self-reported referrals.

Why it matters

A large share of B2B buying conversations happen where no pixel can follow. Channels whose content travels this way, podcasts prominently among them, will always under-report in dashboards, which is why self-reported attribution and CRM notes matter alongside tracked data. The term was coined by Alexis Madrigal in 2012 to describe untrackable referral traffic. The practical response is twofold: create content worth sharing privately, and add a 'how did you hear about us?' field to forms, since self-reported answers are often the only visible trace dark social leaves.
