Power BI Marketing Data Analysis

I have a large set of sales and marketing data and I need a clear, insight-driven analysis that zeroes in on marketing campaign effectiveness. All raw tables are already exported to Excel; what’s missing is the story that shows which campaigns are working, which audiences respond best, and where budget can be trimmed or re-allocated.

Here’s the flow I’m aiming for:
• Clean and structure the existing Excel data, flagging any gaps or anomalies.
• Build a data model in Power BI that links campaigns, spend, impressions, clicks, conversions, and revenue.
• Create intuitive visualisations—think funnel views, ROI heat maps, and time-series performance trends—that allow me to slice by channel, region, and customer segment.
• Summarise key findings in a brief narrative so stakeholders can act on them immediately.

Accuracy matters more than flashy graphics: calculations for cost per acquisition, lifetime value, and incremental lift must reconcile to the penny between Excel and Power BI. I’ll provide sample pivot tables as a reference for expected numbers.

Final deliverables: the cleaned Excel file, the .pbix report, and a short slide deck highlighting the main takeaways. If you’ve previously measured campaign lift or optimised marketing spend using DAX and Power Query, you’ll be up to speed quickly.
