W-Shaped Attribution
AnalyticsAlso: W-Shape Model · Three-Touch Attribution
Quick definition
W-shaped attribution is a multi-touch attribution model that assigns most credit to three specific touchpoints in the customer journey: the first touch, the touch that creates a lead, and the touch that creates an opportunity. The remaining credit is distributed evenly across all other touches in between.
A customer touches all four, then converts.
Credit distributed
W-shaped credits the first touch, the lead-creation touch and the opportunity-creation touch heavily. Middle touches share the rest.
How it varies across Australia
W-shaped attribution is more common in Australian B2B organisations with defined sales stages than in ecommerce or direct-to-consumer businesses. Adoption tends to sit behind U-shaped and time-decay models in overall use, but rises sharply among businesses running structured CRM and marketing automation setups.

Approx 30% creditWhat it actually means
Picture a customer journey as a road trip with a few significant stops. W-shaped attribution says three stops matter most: where the trip started, where the traveller first introduced themselves, and where they agreed to move forward seriously. Every other stop along the way shares the leftover credit equally.
In marketing terms, those three stops are: the first touch that introduced the prospect to your brand, the touch that converted them into a lead, and the touch that converted them from a lead into a sales opportunity. Typically each of those three gets around 30% of the total credit, with the remaining 10% split across middle touches.
The model sits between U-shaped attribution (which only honours first and last touch) and full-path attribution (which adds even more named milestones). It is a rule-based model, which means the weights are fixed by convention, not calculated from your actual data. That makes it easier to implement but means it will always be wrong in a precise sense.
W-shaped attribution works well for B2B businesses where the CRM tracks both lead creation and opportunity creation as distinct events. It rewards upper-funnel awareness work, lead-generation campaigns and mid-funnel sales enablement content differently, which is more honest than last-click for complex sales cycles. Compare it with linear attribution, which treats every touch identically, or with time-decay, which ignores how far back the first touch was.
W-shaped attribution says the introduction, the handshake and the contract all matter. Everything in between matters less.
How it shows up
W-shaped attribution shows up in the channel reports of marketing automation platforms like HubSpot and Marketo, which offer it as a named model. It also shows up in custom attribution setups built on CRM data where the marketing team has defined lead-created and opportunity-created as conversion events.
The practical output is a credit table: each touchpoint in a customer journey receives a percentage of the eventual revenue. Channels that reliably appear at the three key milestones (first touch, lead creation, opportunity creation) will show higher attributed revenue under W-shaped than under last-click. Upper-funnel channels like paid social and content marketing usually benefit most.
The Australian context
Australian B2B businesses often have shorter sales teams and fewer formal pipeline stages than US equivalents, which can make the opportunity-creation milestone harder to define cleanly. The W-shaped model assumes a structured CRM where lead and opportunity stages are tracked separately. Businesses without that infrastructure usually find U-shaped or time-decay attribution more practical to implement without manual data work.

Common questions
When should I use W-shaped attribution over U-shaped?
Use W-shaped when your CRM tracks opportunity creation as a distinct pipeline stage and you want to credit the marketing touch that triggered it. If your funnel only distinguishes between leads and closed deals, U-shaped is simpler and just as honest.
Does W-shaped attribution work in Google Analytics?
Google Analytics 4 does not offer W-shaped attribution natively. It is available in marketing automation platforms like HubSpot and Marketo, or you can build it in a CRM with custom attribution logic. GA4 offers data-driven, last-click, first-click, linear and time-decay out of the box.
How is W-shaped different from full-path attribution?
Full-path attribution adds a fourth named milestone: the closed deal or customer conversion. W-shaped stops at opportunity creation. For businesses with long post-opportunity sales cycles, full-path is more honest. For most B2B marketing teams, W-shaped is practical enough.
Can W-shaped attribution work for ecommerce?
Not well. The model is built around B2B pipeline stages. An ecommerce journey rarely has a lead-creation or opportunity-creation event in the same sense. Time-decay or data-driven attribution is a better fit for direct-to-consumer businesses with high transaction volumes.
