What Is Last-Touch Attribution?
Last-touch attribution assigns 100% of revenue or conversion credit to the final interaction before a lead becomes qualified, an opportunity is created, or a deal closes. It offers simplicity, speed, and directional clarity—especially for organizations early in their measurement maturity.
Last-touch attribution credits the final measurable touchpoint before a key conversion event. This could be the last ad clicked, the final email opened, the last webpage visited, or the last outbound interaction recorded. It is most useful for understanding which programs close the gap and drive conversion readiness, even though it doesn’t reflect the full journey or earlier influences.

How Last-Touch Attribution Works
A straightforward process that maps the final influence before a conversion milestone occurs.
Process Overview
- Define the conversion event — Lead creation, MQL, opportunity creation, or closed-won.
- Track final interactions — Capture the most recent clicks, form fills, emails, calls, or page views.
- Align touchpoint timestamps — Ensure MAP and CRM data synchronize using unified IDs.
- Assign 100% credit — Attribute the entire conversion value to the final touchpoint.
- Analyze patterns — Identify which channels consistently close deals or influence final-stage momentum.
- Compare across segments — Evaluate performance by persona, industry, funnel stage, and product line.
- Align with Sales — Validate whether the final touches correspond to meaningful buyer intent.
