Google Analytics Reports: Which One to Use When

Olamide Sule, founder of Dolphin Analytics: a digital analytics expert based in London delivering solutions for agency and in-house clients.

Most people open Google Analytics 4 looking for one answer and get lost in a menu of reports that all sound plausible. We set up and fix GA4 for agency and in-house teams most weeks, and “which report do I actually open?” is one of the first questions clients ask. So this is the map we give them: the common question on the left, the exact GA4 report and click path on the right.

GA4 organises reporting differently from the old Universal Analytics. Learn the split once and the menu stops feeling random.

What are the reports in Google Analytics 4?

Google Analytics reports come in two kinds: prebuilt Reports for standard questions, and Explorations for custom analysis. Google describes Explorations as going beyond standard reports, with techniques the Reports menu does not offer. Explore is a blank canvas where you build funnels, path breakdowns and free-form tables that no prebuilt view covers.

The Reports menu groups its prebuilt reports into areas such as Realtime, Acquisition, Engagement, Monetisation and Retention, as listed in Google’s overview of Analytics reports. Each area answers a different family of questions. Once you know which family your question belongs to, the right report is two clicks away.

Which GA4 report answers which question?

Start from the question, not the menu. This table maps the questions we hear most to the exact report and the click path to reach it, using the report names in Google’s Reports help section.

Your question	GA4 report	Where to click
Where is my traffic coming from?	Traffic acquisition	Reports > Acquisition > Traffic acquisition
Who are my new visitors and how did they first find me?	User acquisition	Reports > Acquisition > User acquisition
What is happening on the site right now?	Realtime	Reports > Realtime
Which pages and content get the most engagement?	Pages and screens	Reports > Engagement > Pages and screens
Which events and key events are firing?	Events	Reports > Engagement > Events
How many conversions did each channel drive?	Traffic acquisition (with a key event selected)	Reports > Acquisition > Traffic acquisition
How much revenue and which products sold?	Ecommerce purchases	Reports > Monetisation > Ecommerce purchases
Where exactly do users drop off in a flow?	Funnel exploration	Explore > Funnel exploration
What path do users take between pages?	Path exploration	Explore > Path exploration

The sections below explain the four reports people reach for most, and when to leave the prebuilt views behind for Explore.

Where is my traffic coming from?

Open Traffic acquisition (Reports > Acquisition > Traffic acquisition). It groups sessions by default channel group: Organic Search, Paid Search, Direct, Referral, Organic Social and the rest. This is the report for “which channels and campaigns are working”, because it counts the source of each session and lets you add a key event to see conversions by channel.

Sitting next to it is User acquisition, which answers a different question. Google’s comparison of the two reports says User acquisition is scoped to new users (using dimensions like First user source), while Traffic acquisition is scoped to sessions (Session source). Reach for User acquisition when you care about how new users first find the site; reach for Traffic acquisition for ongoing campaign and channel performance. Mixing the two up is the most common reason two people quote different “organic” numbers from the same account.

One trap worth naming: if Direct traffic looks suspiciously large here, that is usually a tracking fault rather than real behaviour. We cover the causes in why direct traffic gets inflated.

What is happening on my site right now?

The Realtime report (Reports > Realtime) shows activity from roughly the last 30 minutes, according to Google’s own reporting documentation: users active now, the pages they are viewing, the events firing and where they came from. It is a live monitor, not an analysis tool.

Use it for one job: checking that something works the moment you ship it. Push a new landing page, trigger a test purchase, publish a campaign, then watch the Realtime report to confirm the pageview and the event show up. If nothing appears within a minute or two, the tag is not firing and you have caught the problem before it costs you a day of data. For anything historical, close Realtime and use the standard reports. Keep recent days at arm’s length: Google’s data freshness page says processing can take 24 to 48 hours, and report data may change during that time.

Which pages and content get the most engagement?

Open Pages and screens (Reports > Engagement > Pages and screens). By default it shows views, active users, average engagement time and key events for each page, per Google’s Pages and screens documentation, so you can see which content earns attention and which quietly does nothing. This is the report for content and SEO questions: blog performance, and where engaged time concentrates.

GA4 measures attention through engaged sessions: Google counts a session as engaged when it lasts longer than 10 seconds, has a key event, or has 2 or more page or screen views, and defines bounce rate as the share of sessions that were not engaged (engagement rate and bounce rate). Read this report with that shift in mind. If those metrics are new to you, we explain them in bounce rate and engaged sessions in GA4. Pair Pages and screens with the Events report (Reports > Engagement > Events) when you need to confirm a specific interaction, like a form submit or a video play, is being recorded.

When should you use Explorations instead of reports?

Move to Explore the moment a prebuilt report cannot shape the question the way you need. Explorations are custom: you drag dimensions and metrics onto a canvas and build the exact view. Google’s Explorations guide lists the techniques. The two most useful for marketers are Funnel exploration (Explore > Funnel exploration), which shows the steps users take toward completing a task so you can see where they drop out, and Path exploration (Explore > Path exploration), which shows the paths users take through your site or app. Segment overlap shows how different user segments relate to each other, and free-form exploration lays data out as a table or chart you arrange yourself.

Explore has real limits. Explorations only show user-level and event-level data inside your retention setting, which is 2 months or 14 months on a standard property, per Google’s data-retention settings. Check yours under Admin > Data collection and modification > Data retention before planning a year-over-year funnel, because data older than the setting has aged out. Large queries can also be sampled once a single exploration crosses the reporting threshold Google documents for GA4, which is where teams on high-traffic accounts start exporting to BigQuery for unsampled analysis.

When native GA4 reports stop being enough

GA4’s reports are strong for single-property, in-tool questions. They strain in three predictable places. First, they only show GA4 data, so a report combining GA4 with Google Ads spend, Shopify revenue and email performance in one view is not something the native reports do. Second, the retention window (14 months at most on a standard property) and sampling on large Explorations get in the way of long-range or high-volume analysis. Third, sharing a live, on-brand report with a client or a board means rebuilding the view somewhere they can actually read it.

That third point is where most teams reach for Looker Studio, which Google now calls Data Studio. Google’s guide to connecting Google Analytics says you can connect GA4 properties to it, build custom reports and dashboards, and share them with your team or other users. The tool is the bridge between “the answer exists in GA4” and “the client can see it every Monday without logging in”.

How we handle reporting for clients

When reporting eats a team’s week, we build the automated reporting layer that replaces the manual export-and-paste cycle, pulling GA4 and the other sources into one dependable view. Here is what that looked like for a B2B media business.

Automated reporting saved a B2B media business around £100k and 2,600 hours a year. They resold the reporting to their own clients at 3x their investment.

That is the pattern: get the numbers right once, then stop paying for them by the hour.

If your GA4 reports and your other tools tell different stories, the problem is usually the tracking underneath, not the report you picked. Tell us what’s broken, or book a call. You get a considered reply from a person.
