What is Last-click Attribution? Definition and Marketing Examples

Last-click attribution is an attribution model that gives full conversion credit to the final known source or touchpoint before a visitor converts. If someone clicks an email link and then signs up, email receives all credit under last-click attribution.

Last-click attribution is simple and easy to report, but it can hide the channels that helped earlier in the journey.

Last-click attribution example

A visitor journey might look like this:

  1. Organic search blog post
  2. Partner review page
  3. Email campaign
  4. Signup

With last-click attribution, the email campaign receives full credit. Organic search and the partner review assisted the conversion but get no direct credit.

When last-click attribution is useful

Last-click attribution can help answer: "What closed the conversion?" It is useful for short buying journeys, simple campaigns, and quick reporting.

It is less useful when customer journeys are long, involve multiple stakeholders, or include many educational touchpoints.

Limitations of last-click attribution

Last-click attribution often overvalues branded search, direct traffic, retargeting, and email while undervaluing content, referrals, social discovery, and early-stage campaigns.
