Deterministic vs. Probabilistic Attribution: Which One is Right for You?
In this blog, we put deterministic and probabilistic approaches to cross-device and multi-channel marketing attribution side by side. The idea is to enable advertisers to pick the right approach for reporting on user journeys and quantifying their campaign effectiveness.
Deterministic Attribution: The Gold Standard
Deterministic cross-device tracking is the most accurate method of multi-device attribution, using solid, sure identifiers such as email addresses, login values or other account based data. When someone signs into YouTube on their laptop then uses the mobile app, deterministic tracking can immediately identify them as one in the same person with near-100% accuracy.
However, the benefits of deterministic attribution are substantial:
- Near-perfect accuracy: No guesswork involved.
- Privacy-safe practices: Leveraging first-party information.
- Scalable personalization: Unified user profiles.
- Regulatory compliance: Transparent data usage.
But deterministic tracking does have significant shortcomings. It functions only with people who have registered as users or customers — those for whom it has at least some identifiable information, creating gaps in its ability to track new site visitors and anonymous browsers.
Probabilistic Attribution: Filling the Gaps
Probabilistic cross-device takes advantage of cutting-edge algorithms and statistical models to make predictions about likely device links through which a user can be recognized even when not logged into an account and personal data protection. "For that, you'd want to analyze other factors such as IP address, device proximity, browsing patterns, user location and operating systems (among others) and join the dots using probabilities to associate devices with people."
More flexible than deterministic approaches, probabilistic attribution relies on educated hunches rather than hard-and-fast identifiers. Its performance is highly sensitive to the scale and quality of anonymous data points included in the probabilistic model. For such critical application that require high accuracy, the deterministic approach still works better.
Hybrids: The Best of Both?
The rise of the hybrids In fact, most leading attribution platforms now rely on a hybrid model that incorporates both deterministic and probabilistic approaches. By performing a deterministic match when an actual ID is present and resorting to probability based on some matching elements for a user or when the same deterministic data do not exist. This is the best of both worlds in terms of accuracy and coverage, ensuring you have as complete a picture of your customers’ journey as possible.
