What is a user journey?

The map and the territory

Journey mapping is a useful discipline that has one persistent failure mode: mistaking the journey you can observe for the journey the user took.

The observed journey is assembled from touchpoints your systems recorded. The actual journey included conversations with friends, a review read on a phone you never saw, a competitor comparison, and increasingly a recommendation inside an AI assistant that left no trace anywhere in your data.

How incomplete the observed journey now is

• Cross-device steps are largely invisible without a login — see cross-device tracking.
• Unclicked exposure leaves no record at all.
• Identifier loss breaks the stitching between the steps that were recorded.
• AI assistant influence typically arrives with no referrer, landing in direct or organic.
• Word of mouth has never been observable and remains a large share of most journeys.

Using journey maps well

As a design tool they remain excellent — understanding what a user is trying to do at each stage improves products regardless of what is measurable.

As an attribution basis they have become weak, because assigning credit along a path requires the path to be roughly complete. Where it is not, the model over-credits whatever is still visible, which is usually the channels closest to conversion.

The practical split is to use journey mapping for product and creative decisions, and causal measurement for budget decisions — see incrementality.
