  • E-Commerce Funnel Dashboard (GA4 + BigQuery)

    Created an interactive dashboard for analyzing the sales funnel of an online store, which allows marketing teams to quickly assess key metrics and analyze user behavior.
    What has been implemented:
    - KPI: Sessions, Orders, Purchases, Conversion Rate
    - 7-step funnel - from website visit to purchase
    - Segmentation by traffic source, device, language, OS, landing page
    - Cleaned and standardized filters → built readable names instead of raw GA4 values
    - Added the parameter “Selected Event” to change the key event and analyze conversions to it
    - 5+ interactive charts, drill-downs, and time filters
    What this means for the business:
    - see where users drop out of the funnel
    - assess the effectiveness of different traffic sources
    - identify problems in UX or payment processes
    - make data-driven decisions
