Does App Traffic Include a Referer in Snowplow?

Tracking traffic sources for app-based interactions on platforms like Facebook, Instagram, and Twitter poses challenges due to the absence of referer information in HTTP headers, unlike web traffic. Snowplow addresses this by offering strategies such as leveraging campaign attribution, custom event tracking, UTM parameters, and user identifiers to capture source and user interaction data. Although most mobile apps do not pass referer information, Snowplow's event-based model allows data modelers to use campaign parameters and custom contexts to maintain effective attribution models and gain insights into user journeys. Best practices include optimizing attribution logic, implementing fallback logic for missing data, and monitoring redirect patterns to identify app-originated traffic.
