#35. Cross-Platform CRO Dashboards in Looker Studio

Conversion Rate Optimization (CRO) is a high-impact, data-driven function—but it’s only as effective as the visibility you have across tools and touchpoints. That’s why building cross-platform CRO dashboards in Looker Studio is essential for understanding what’s working, what’s not, and where to focus your testing efforts.

In this post, we’ll walk through how to connect data sources, design visualizations, and interpret insights that drive real conversion improvements.

Why Cross-Platform Dashboards for CRO?

CRO data lives across:

  • GA4 (user behavior, event tracking)
  • HubSpot or Marketo (form fills, email engagement)
  • Hotjar or Clarity (session recordings, heatmaps)
  • A/B testing tools (Google Optimize, Optimizely)
  • CRM (conversion outcomes, pipeline progress)

A single dashboard in Looker Studio gives you:

  • Full visibility across the funnel
  • Faster insights into variant performance
  • Alignment between marketing, analytics, and UX teams

Step 1: Centralize CRO Data into BigQuery

Use ETL tools (Fivetran, Supermetrics, Stitch) to ingest data from:

  • GA4: Pageviews, events, conversion rates
  • HubSpot: Form conversions, lifecycle stage
  • A/B test results: Variant, traffic split, conversion outcome
  • Heatmap tools: Exported insights or screenshots linked by URL/session

Structure your schema to support:

  • Funnel stage analysis
  • Test and control group comparisons
  • User journeys with conversion markers

Step 2: Design Your CRO Dashboard in Looker Studio

Start with clear KPIs and use a modular layout:

Top-Level Metrics:

  • Conversion rate by test variant
  • Bounce rate and time on page
  • Form abandonment rate
  • Funnel step drop-off percentages

Mid-Funnel Views:

  • Scroll depth by page or template
  • Session replay links by variant or traffic source
  • Engagement by UTM, device, or persona

Bottom-of-Funnel Views:

  • SQL/MQL conversion by form and page
  • Win rate by A/B test group
  • Revenue per visitor (RPV)

Step 3: Add Filters and Custom Interactions

Let users self-serve insights:

  • Filter by traffic source, campaign, device, and date
  • Add dropdown for variant/test group selection
  • Use optional parameters to compare different CRO KPIs side-by-side

Add drill-through links to:

  • Full session replays (Hotjar/Clarity)
  • HubSpot contact records or Salesforce deal pages

Step 4: Automate Reporting and Alerts

Schedule regular reports for stakeholders:

  • Weekly snapshot emails to marketing, product, and analytics
  • Slack alerts for major test wins/losses
  • Trend alerts on rising abandonment or bounce rates

Step 5: Connect CRO Dashboards to Action

Use dashboards to:

  • Prioritize next A/B tests based on biggest drop-offs
  • Trigger UX audits on high-bounce landing pages
  • Inform copywriting and design based on scroll and click data
  • Feed learnings into lifecycle marketing workflows

Final Thoughts

A well-built CRO dashboard in Looker Studio isn’t just a reporting tool—it’s a decision-making engine. With clear visualizations, cross-platform context, and actionable filters, your team can move faster and test smarter.
