# Attribution Model

**Category:** Digital Marketing & PPC | **Updated:** 2026-03-05

An attribution model is a framework that determines how credit for conversions is assigned across the various marketing touchpoints (organic search, paid ads, social, email) a customer interacts with before converting.

## What Is an Attribution Model?
An attribution model defines rules for assigning conversion credit to marketing channels and touchpoints along the customer journey. Common models: **Last Click** (100% credit to the last touchpoint), **First Click** (100% to the first), **Linear** (equal credit to all), **Time Decay** (more credit to recent touchpoints), **Position-Based** (40% first, 40% last, 20% middle), and **Data-Driven** (AI determines credit based on actual conversion paths).

## Why Attribution Matters for SEO
Under last-click attribution, SEO often gets **under-credited** because organic search frequently plays an awareness/research role early in the journey, while the final conversion happens through a direct visit or branded search. Proper multi-touch attribution reveals SEO's true contribution. Data-driven attribution in GA4 shows that organic search often assists 2-3x more conversions than it directly drives.

## How to Choose the Right Attribution Model
Use **Data-Driven attribution** (GA4's default) when you have sufficient conversion data — it uses machine learning to assign accurate credit. For lower-traffic sites, use Position-Based (gives credit to both discovery and closing channels). Review GA4's Conversion Paths report to understand your customer journey. Compare models side-by-side to see how SEO's value changes. Always analyze assisted conversions alongside direct conversions to see SEO's full impact.
