W-Shaped Attribution
W-shaped attribution is a multi-touch model that gives major credit to three milestones: the first touch, the lead-creation touch, and the opportunity-creation touch, with the rest spread across other interactions.
In depth
Where U-shaped recognizes two peaks, W-shaped adds a third by acknowledging the moment a lead becomes a sales opportunity. The conventional split assigns about 30% each to the first touch, the conversion to a known lead, and the conversion to an opportunity, leaving roughly 10% for everything else. This makes it well suited to B2B funnels where marketing and sales hand off mid-journey and both teams need credit for the stages they influenced.
The biggest pitfall is data hygiene: W-shaped attribution only works if your CRM cleanly stamps when a contact became a lead and when they became an opportunity, otherwise the model collapses into noise. In a quiz-funnel context, the first touch is the ad or organic discovery, the lead-creation touch is the scorecard quiz that captures and scores the prospect, and the opportunity touch is the follow-up that sales books, so the model can fairly reward the quiz for generating qualified pipeline rather than just raw clicks.
Example in practice
Frequently asked questions
What three touchpoints does W-shaped attribution credit?
It gives major credit to the first touch, the touch that creates a known lead, and the touch that creates a sales opportunity. The remaining credit is spread across all other interactions.
Is W-shaped better than U-shaped attribution?
Neither is universally better; W-shaped suits longer B2B cycles with a clear opportunity stage, while U-shaped fits simpler funnels. Choose based on whether your sales process has a distinct opportunity milestone.
What data do I need for W-shaped attribution to work?
You need accurate timestamps in your CRM for when a contact became a lead and when they became an opportunity. Without clean stage tracking, the model cannot place its three credit points correctly.
