Linear Attribution

Updated on Jul 18, 2026

Learn what linear attribution is, how equal credit is assigned across a conversion path, and why teams should treat it as a reporting model.

Key Takeaway

Linear attribution assigns equal conversion credit to each recorded touchpoint in a path.
It is easy to explain but assumes each touchpoint has equal influence.
Google's legacy Universal Analytics documentation explains the model, while current GA4 availability differs by report and product.

What Is Linear Attribution?

Linear attribution is a marketing measurement model that gives equal conversion credit to every recorded touchpoint in a conversion path. If four qualifying touches precede a conversion, each receives one quarter of the assigned credit.

It is a simple multi-touch model. Its central assumption is also its limitation: every recorded touch is treated as equally influential.

How Linear Attribution Works

An analytics system identifies a path within its reporting rules and lookback window, then divides the conversion value equally among the eligible steps. Missing consent, device changes, untracked channels, and platform definitions can change the path before the calculation begins.

Google's legacy Universal Analytics documentation describes this model. Google also documents that linear attribution is no longer available in GA4 Attribution reports, so teams must distinguish a conceptual model from current product availability.

Why It Matters for Mobile Workflows

Mobile customer journeys can cross app, web, email, and campaign surfaces. Linear attribution can be a useful explanatory comparison, but it should not be treated as proof that each interaction had the same causal value.

For mobile automation, record approved events accurately. For cloud phones, reproduce measurement issues with documented app, consent, and device conditions.

Risks and Best Practices

Do not use an equal-credit report as a universal budget rule. Document its assumptions, compare with other available reporting views, and be explicit about consent and data-quality gaps. Confirm the attribution options actually supported by the current analytics product.

MoiMobi Perspective

MoiMobi treats linear attribution as a transparent conceptual lens. Its value is clarity about its rule, not a claim to perfectly explain every conversion.

Bottom Line

Linear attribution splits credit evenly across recorded touches. It is easy to audit, but it can oversimplify real customer journeys and may not be available in current analytics tools.

How MoiMobi Fits

MoiMobi explains linear attribution as a transparent reporting convention that should be interpreted with current platform capabilities and data limitations.

FAQ

What is linear attribution?

It is an attribution model that distributes equal conversion credit across each recorded touchpoint in a conversion path.

What is its main assumption?

It assumes every credited touchpoint contributed equally, which may not match the customer's actual decision process.

Is linear attribution available in GA4?

Google documents that first-click, linear, time-decay, and position-based models were no longer available in GA4 Attribution reports from November 2023.
