Marketing Attribution

The practice of assigning credit for a conversion across the marketing touchpoints a player encountered before signing up or depositing.

Definition

Players rarely convert from a single ad; they see affiliates, search, social, and email before acting, and attribution decides how to divide the credit. Models range from simple rules like first-touch and last-touch to multi-touch and data-driven approaches that weight each interaction. Attribution drives budget decisions, so getting it wrong misallocates spend — last-click, for instance, over-credits the final affiliate and under-credits the brand activity that started the journey. Privacy changes such as cookie deprecation and mobile tracking limits have made deterministic tracking harder, pushing operators toward modelled and incrementality-based measurement.

Worked example

A player clicks a review-site affiliate, later a paid-search ad, then converts from a retargeting email; last-touch credits the email fully, while a data-driven model might split credit 40/35/25 across the three touchpoints.

Why it matters

For a learner, it explains why 'which ad worked?' is genuinely hard. For a professional, it is the foundation of budget allocation and affiliate payment, increasingly reliant on modelling as tracking degrades.

Note: There is no single 'correct' attribution model; each embeds assumptions, and results shift with the model chosen and with tracking-privacy constraints.
