List the questions leaders ask monthly, then build one summary page answering them (qualified leads or revenue from your own records, spend, cost per lead by channel, trends) and one page per channel. Give every number a comparison period, keep data sources documented, and plan around GA4 API quotas.
The tool
Google's documentation for the product, where Looker Studio help pages now redirect, is titled Data Studio and describes it as a no-cost tool for building reports and dashboards; a Pro edition adds enterprise-grade collaboration and administration features. It connects to Google products such as GA4 and to other data sources, so one report can combine them.
Start with the questions
Write down the questions before choosing a chart. For most marketing teams they are:
- Are we getting more qualified leads (or sales) than last month and last year?
- Which channels bring them, and at what cost per lead or sale?
- Where is spend going, and is it moving toward what works?
- Which pages and campaigns turn visitors into leads?
Page 1: the summary
One screen, readable in a minute:
- Qualified leads or revenue for the month, from your lead record or store, against last month and last year.
- Spend by channel.
- Cost per qualified lead or sale by channel.
- A 13-month trend line for leads and spend.
- Three notes in words: what changed and why.
Pages 2 onward: one per channel
Give each channel its own page: organic search (sessions and leads by landing page, with Search Console queries), paid search and paid social (spend, clicks, cost per lead and leads by campaign), and email (sends, clicks and leads by campaign). Keep the same layout on every page so readers know where to look.
Where the numbers should come from
Take leads and revenue from your own lead record, CRM or store, not from analytics events: a GA4 key event is a signal, and leads are people in your records. Use GA4 for traffic, behavior and channel, ad platforms for spend, and Search Console for search queries. Document each source on a final page, with who owns it.
GA4 limits worth knowing
Busy dashboards built on GA4 hit limits:
- API quotas: Google's GA4 connector page says reports that connect to GA4 data are subject to the Google Analytics Data API quotas, and that reports exceeding them may show an error.
- Segments and comparisons: the same page says they are not supported through the connector.
- Retention: GA4's data retention setting (2 or 14 months) limits explorations; set it to 14 months.
Keeping the dashboard trusted
A dashboard is trusted until one number is wrong:
- Every number with a comparison period and a definition on hover.
- Fewer charts: each one answers a listed question.
- A monthly check that dashboard leads match the lead record.
- A named owner who fixes broken sources within a week.
Looker Studio or a BI tool?
For marketing reporting from Google sources, Looker Studio is usually enough. When reporting spans finance, operations and sales data from many systems, a business intelligence tool with a data model may fit better; our business intelligence dashboards work covers that case.
Conclusion
A Looker Studio dashboard for marketing should answer the few questions leaders ask monthly: one summary page with qualified leads or revenue from your own records, spend, cost per lead by channel and trends, then one page per channel. Google's documentation describes the tool as no-cost and notes that GA4-connected reports are subject to API quotas, so keep dashboards focused.
