Step 3: Define Your Dashboard Goals

Before adding charts, decide what question your dashboard should answer.

Avoid creating dashboards filled with unnecessary visuals.

A good dashboard answers questions like:

• Which marketing channels generate revenue?
• Where are customers coming from?

A simple business dashboard usually contains:

Key Performance Indicators (KPIs)

• Average Order Value

KPIs give users an immediate understanding of performance.

Step 4: Add Charts and Visual Elements

Looker Studio provides multiple visualization options.

Common dashboard components include:

Scorecards

Used for showing important numbers.

Time Series Charts

Useful for trends.

Bar Charts

Great for comparisons.

Example:

Sales by product category.

Pie Charts

Useful for simple proportions.

Tables

Best for detailed information.

Step 5: Add Filters and Interactivity

A professional BI dashboard should allow users to explore data.

Useful features include:

Date Filters

Category Filters

Users can view:

• Specific products

Drill-Down Reports

This transforms a static report into an interactive analytics tool.

Step 6: Design a Clean Dashboard Layout

Good dashboards are easy to understand.

Follow these design principles:

Keep It Simple

Avoid adding too many charts.

A dashboard should highlight insights, not overwhelm users.
