How do you attribute pipeline from LinkedIn and dark social?
You cannot capture it with last-click. Buyers complete about 61% of the journey before contacting a seller, self-reported attribution misses roughly 23% of pipeline and about half of the answers are too vague to use, and 56% of B2B marketers say they simply cannot attribute ROI or track the journey. The fix is signal-level tracking: tie a specific engagement to a specific meeting to a specific CRM opportunity.

Why LinkedIn pipeline is undercounted
Standard analytics see the last click, not the journey. But buyers complete about 61% of the journey before they ever contact a seller (6sense, 2025), and much of that happens through peers rather than vendors: only 15% consult vendor materials versus 54% who rely on user reviews (TrustRadius, 2023). The influence that shapes the shortlist is largely invisible to last-click tracking.
Dark social, explained
Dark social is the discovery and evaluation that happens in places you cannot track: private feeds, DMs, community threads, forwarded posts, and word of mouth. It is where a lot of B2B demand actually forms, and it leaves almost no trackable footprint.
Self-reported attribution is not enough
Asking "how did you hear about us" helps, but it is leaky. In a controlled test, self-reported attribution failed to match about 23% of pipeline, roughly 30% of buyers skipped the question, and about half of the answers were too vague to action (Dreamdata). It is not surprising that 56% of B2B marketers say they cannot attribute ROI or track the customer journey (CMI, 2025).
A signal-to-opportunity attribution model
The fix is to track at the signal level. Instead of guessing at a channel, connect a specific engagement (this person commented on this post) to the meeting it produced and the CRM opportunity that followed. When you can name the post that led to the meeting, you can finally prove the channel.
Slingapult's read: if you can name the exact engagement that led to a meeting, dark social stops being dark. That is the attribution most teams are missing.
