First-click attribution for fashion teams

What does first mean?

First means first within the observations and rules available to the report. It does not necessarily mean the first time a person ever encountered the brand. Earlier interactions may be outside the window, on another device or absent from the dataset. A model label cannot restore those missing observations.

For a seasonal launch, ask whether the available path starts early enough to capture the initial campaign. If the observed journey begins with a later branded search, the report may assign discovery credit to an interaction that was actually a return visit.

Use it to explore discovery

This perspective can surface a question about channels that introduce a collection or brand. Compare the audience, assortment and commercial outcomes associated with those starting interactions. Keep acquisition quality visible: introducing many visitors is different from bringing relevant new customers.

Do not turn discovery credit directly into a budget instruction. The later product explanation, fit information and follow-up may still matter to conversion. First-click attribution deliberately omits that sharing of credit.

Make the comparison repeatable

Keep the same eligible paths and purchase value when comparing first-click with another rule. If the underlying cohort or reporting window changes at the same time, the difference is not solely a model comparison.

Document identity coverage, excluded channels and the selection window. Revisit the definition when changing tracking or adding a source. Treat this as a general allocation concept; verify which reports and models your chosen platform currently supports.

Turn the guide into a useful review

1. Define the first eligible interaction.
2. Check whether the observation window covers discovery.
3. Compare customer quality and commercial context.
4. Keep closing interactions visible in the wider review.
