Overview
Marketing Attribution is the practice of tracking the original source, medium, campaign, and referrer that first brought a user to the platform, enabling measurement of acquisition channel effectiveness.
Description
When a user arrives at the platform for the first time, the system captures UTM parameters (source, medium, campaign, term, content) and the HTTP referrer from the landing URL. These values are stored in the browser's local storage under a first-touch model: once captured, they are never overwritten by subsequent visits, preserving the original acquisition channel. When the user later signs up or converts, these stored attribution values are sent to the backend and associated with the user account.
This approach allows the marketing team to answer questions like "which blog post drove the most signups?" or "what percentage of paying customers came from organic search?" without requiring third-party analytics tools.
Usage
Use first-touch attribution when:
- Measuring the effectiveness of marketing campaigns and content.
- Attributing user signups to their original acquisition channel.
- Building internal analytics dashboards for marketing ROI.
- Avoiding dependency on third-party cookie-based tracking systems.
Theoretical Basis
First-touch attribution implements the simplest attribution model in marketing analytics. In contrast to multi-touch models (linear, time-decay, position-based) that distribute credit across all touchpoints, first-touch assigns 100% of the credit to the initial interaction. The model is implemented as an idempotent write: the attribution data is stored once and subsequent attempts to write are no-ops. UTM parameters follow the Urchin Tracking Module standard, a convention for encoding campaign metadata in URL query parameters.
