Looker Studio is a free, browser-based tool from Google for turning data into interactive reports and dashboards. It was previously known as Google Data Studio. Many small businesses and marketing teams use it because it connects easily to spreadsheets and other common data sources.
What Looker Studio does
At a basic level, it lets you:
- Connect to a data source, such as a Google Sheet.
- Add charts, tables and scorecards to a canvas.
- Add filters and date controls so viewers can explore.
- Share the report with a link, like a shared document.
Common business uses
Marketing performance reports
Summarize spend, clicks, conversions and cost per conversion by channel or campaign.
Sales overviews
Track revenue, orders and top products over time.
Operations tracking
Monitor support tickets, delivery times or inventory levels.
Client reporting
Freelancers and agencies share a consistent monthly report instead of emailing spreadsheets.
The building blocks
| Element | Purpose |
|---|---|
| Data source | Where the numbers come from |
| Dimensions | Categories you group by (date, product, channel) |
| Metrics | Numbers you measure (revenue, sessions, orders) |
| Scorecard | One headline number, optionally compared to a prior period |
| Controls | Date ranges and drop-down filters for viewers |
Getting started with a spreadsheet
- Prepare a tidy Google Sheet with one header row.
- Create a new report and add the sheet as a data source.
- Check that each field has the right type (date, number, text).
- Add a scorecard for your main metric, then a time-series chart.
- Add a date range control and test it.
Limitations to keep in mind
Looker Studio is excellent for reporting, but it is not a replacement for careful data preparation. If the source sheet has errors, the dashboard will display them beautifully. Very large datasets can also make reports slow.
Where it fits in your learning
We recommend learning spreadsheet basics first, then dashboards. Our Looker Studio week focuses on dashboard design principles that also apply to other tools. For a tool-agnostic guide, see how to build your first business dashboard.
