Unlock Accurate ROI: Standardize Messy Campaign Data in Your BI Tool

Are your social media campaigns a mess in Google Analytics? Inconsistent UTM tags like 'facebook', 'Facebook', and 'fb' fragment your data, making it impossible to see the true performance of a channel. This leads to guesswork, wasted ad spend, and an inability to prove the ROI of your marketing efforts.


This playbook shows you how to create a clean, unified view of your marketing performance without altering your raw data. By connecting Google Analytics directly to Looker Studio, you'll apply cleansing and grouping rules *within the BI tool's data model*. Using calculated fields and CASE statements, you can consolidate variations (like 'fb' and 'Facebook' into a single 'Social' channel) on the fly. This gives you pristine, trustworthy reports while preserving the original, unaltered data in Google Analytics.

Expected Outcomes

  • An aggregated, single source of truth for campaign performance, even with inconsistent source tagging.
  • Accurate measurement of channel-specific ROI and conversion rates.
  • The ability to make data-driven decisions on marketing budget allocation.
  • Preservation of original, raw Google Analytics data for complete data integrity.
  • A scalable reporting framework that automatically cleans new data as it comes in.

Integration Logic

  • Looker Studio GA4 Connector

    This is a native, one-way data connection where Looker Studio acts as the client. Using its built-in Google Analytics connector, Looker Studio directly queries the Google Analytics Data API for a specified GA4 property. Users select the dimensions and metrics they need, and Looker Studio pulls this data to populate charts and tables within a report. The data flow is from GA4 to Looker Studio upon report load or a scheduled data refresh.
