Google Looker Studio (formerly Data Studio) is the most underutilised free tool in digital marketing. It connects to 800+ data sources, updates in real time, and produces dashboards indistinguishable from those built on £500/month BI platforms.

Key Data Sources to Connect

Looker Studio native connectors

Data SourceWhat You GetSetup Time
Google Analytics 4Website traffic, conversions, user behaviour5 minutes
Google Search ConsoleOrganic keywords, positions, CTR5 minutes
Google AdsCampaign performance, spend, ROAS5 minutes
Google SheetsAny custom data you track manually10 minutes

Dashboard Structure

  • Page 1: Executive overview — 5 metrics a CEO looks at weekly
  • Page 2: Traffic and acquisition — where visitors come from and at what cost
  • Page 3: Conversion funnel — from visit to lead to customer
  • Page 4: Channel deep-dives — one page per major marketing channel

Pro Tip

Build blended data sources to combine metrics from different platforms. Combine Google Ads cost data with CRM revenue data to calculate true ROAS in one chart. This is where Looker Studio becomes genuinely powerful.
