To report reach data correctly, you must map the data correctly. Consider these best practices for optimal results.
- Set up an individual data stream for each granularity of reach that you want to report on.
- Don’t include non-reach measurements because they duplicate the data.
- Don’t map frequency because it appears incorrectly at an aggregated level. Frequency data is at the user level and can’t be pulled at an aggregated level. To calculate frequency, create a calculated measurement outside of the mapping for any granularity of reach that you set up. For example, Impressions/Reach.
- Always select lifetime as the aggregation function.
- Map reach to a delivery custom metric that you aren’t using to easily know which granularity of reach you’re reporting.
