First-Click Attribution
AnalyticsAlso: First Touch Attribution · First Interaction Attribution
Quick definition
First-click attribution is an attribution model that assigns 100% of the credit for a conversion to the first marketing touchpoint a customer interacted with. If a customer clicked a social ad six weeks before buying, that ad gets all the credit regardless of what happened between then and the sale.
A customer touches all four, then converts.
Credit distributed
First-click hands everything to the social ad that introduced the customer. The retargeting and direct visit that closed them get nothing.
How it varies across Australia
First-click attribution is rarely used as a primary reporting model in Australian businesses today. It shows up most often as a secondary lens alongside last-click or data-driven models, specifically to evaluate awareness and prospecting campaigns that rarely close on first contact.

First-click attribution answers one question well: what introduced this customer to us? If you are running prospecting campaigns on paid social, organic search or display, and you want to understand which channels are doing the work of discovery, first-click gives you a clean read on that.
The mechanics are straightforward. When a customer converts, you look back at their journey and find the very first touchpoint recorded. That touchpoint gets 100% of the credit. Everything in between, the retargeting ad, the email sequence, the direct visit before checkout, gets nothing.
That completeness is also its limitation. First-click is the attribution equivalent of crediting the person who introduced you to your partner and ignoring the two years of relationship that followed. It overweights awareness channels and systematically undervalues the nurture and closing work that converted curiosity into revenue.
Where first-click earns its place is in the side-by-side comparison. Run it alongside last-click attribution and the gap between them reveals where your funnel is doing real work. A channel that appears in first-click but disappears in last-click is opening doors. A channel that dominates last-click but is absent in first-click is closing them. Both are valuable. Neither deserves all the credit.
First-click tells you how people found you. It tells you nothing about why they stayed.
How it shows up
First-click attribution shows up in analytics platforms as one model option among several. In Google Analytics 4, it appears in the attribution comparison report where you can toggle between models and watch how credit redistributes across channels. In ad platforms like Meta, first-touch attribution is sometimes called first-interaction and sits behind a window setting.
The most instructive place to read first-click data is in comparison with last-click. If organic search dominates first-click but paid search dominates last-click, your SEO is doing discovery work that paid search closes. That is a finding about your funnel, not just your attribution model.
The Australian context
Australian purchase journeys tend to be shorter than US equivalents in most consumer categories, partly because the media market is smaller and retargeting pools saturate faster. That compresses the gap between first-click and last-click models. Even so, categories with longer consideration cycles like mortgages, private health insurance and B2B software show meaningful differences between first-touch and last-touch credit, and Australian marketers in those categories are increasingly using both models side by side.

Common questions
When should I use first-click attribution?
Use it as a secondary model alongside your primary model to evaluate awareness and prospecting channels. It is most useful in longer consideration categories where discovery happens well before purchase. It should rarely be your only attribution model.
How does first-click attribution differ from multi-touch attribution?
First-click gives 100% of the credit to one touchpoint. Multi-touch attribution distributes credit across several touchpoints in the journey using a chosen rule or algorithm. Multi-touch is more complete but requires more data and more deliberate setup.
Does Google Analytics 4 support first-click attribution?
Yes. Google Analytics 4 includes first-click as one of the rule-based attribution models available in the attribution comparison report. You can toggle between models to see how credit shifts across your channels without changing your primary reporting model.
Why does my paid social look so strong in first-click but weak in last-click?
Paid social typically introduces customers to a brand but rarely closes the sale directly. First-click rewards that discovery work. Last-click ignores it because something else, usually a brand search or direct visit, preceded the actual purchase. Both readings are real.
