Quick Definition
Last-touch attribution is an attribution model that assigns all or most conversion credit to the last marketing touchpoint before a conversion. Last-touch attribution emphasizes the importance of conversion activities and is commonly used because it's simple to implement. However, it doesn't account for the contribution of earlier touchpoints in the buyer journey.
Why It Matters
Last-touch attribution is valuable for understanding which channels drive conversions, but it doesn't provide a complete picture of marketing effectiveness. It may over-value conversion activities and under-value awareness and nurturing activities.
How It Works
Last-touch attribution works by: tracking the last marketing touchpoint before a conversion, recording that touchpoint, and assigning all or most conversion credit to that last touchpoint. This model emphasizes the importance of conversion activities.
Real-World B2B Example
A B2B SaaS company uses last-touch attribution to understand which channels drive conversions. They discover that sales calls drive 70% of last touches, so they credit sales calls with conversions. However, this doesn't account for the contribution of content marketing, webinars, and other nurturing activities that prepared the prospect for the sales call.
Common Use Cases

Common Mistakes to Avoid

- Over-valuing conversion channels based on last-touch data
- Not using multi-touch attribution for a more complete picture
