Proprietary Columns

​

Overview

The prefix sm_ in a column name indicates that the column is proprietary to SourceMedium, meaning that the data contained within is a function of SourceMedium’s data transformations. This prefix helps to quickly identifying SourceMedium-specific fields that have been materially enriched through a process of cleaning or imputing.

For example, sm_source_medium is a field derived from last-click attribution data from Shopify, Google Analytics, GA4, Elevar, Blotout, Littledata, referring domains, and other sources of last-click UTM parameters.
