Definition
Last non-direct click attribution ignores direct traffic and assigns credit to the last known non-direct channel before conversion.
Example
If a user visits from an email, then returns via direct and buys, the email gets credit.
How to use it
- Common in analytics tools because direct traffic often represents unknown or returning behavior.
- Keep definitions consistent when comparing with platform reports.
- Pair with conversion lag to avoid over-crediting late touches.
Common mistakes
- Treating last non-direct click as causal for every conversion.
- Comparing it to platform attribution without aligning windows.
Measured as
Measure Last Non-direct Click with a fixed attribution window, conversion event, and spend basis before comparing campaigns or creative tests.
