The Data Studio report contains 6 key sections:

  1. FUNNEL VISUALIZATION A high-level view from keywords to conversions
  2. GA Traffic + conversions by location
  3. GMB Actions + reviews
  4. GSC Local keyword explorer

The report reads a Google Sheets backend, where you can set your location names, and configure all of the unique joining between GMB / GA / GSC data that happens in the Sheet.
