GA4 Explorations: Reports That Answer Real Business Questions

Two settings to check before you build anything

GA4's standard Reports section tells you what happened: sessions, users, key events by channel. Explorations, under the Explore tab, are where you find out why, and they are the part most business owners never open. Before building your first one, fix two settings that silently limit what you can see.

First, data retention. Explorations query event-level data, and on the free tier GA4 keeps that for two months by default. Go to Admin, then Data settings, then Data retention, and change it to 14 months. The change is not retroactive, so do it today even if you build nothing this week.

Second, key events. Since 2024, GA4 has used 'key events' for what used to be called conversions: form submissions, calls, purchases, quote requests. Every exploration below pivots on them, so if yours are not set up properly, that is step zero.

Report 1: the funnel, or where enquiries stall

Business question: people visit the site, so why do so few get in touch?

• 1. Open Explore and choose Funnel exploration.
• 2. Define steps that mirror your customer journey. For a service business: session start, then a service page view, then form_start, then your enquiry key event. For ecommerce: view_item, add_to_cart, begin_checkout, purchase.
• 3. Set the funnel to open, so visitors who land mid-journey (straight onto a service page from Google, say) are still counted.
• 4. Add Device category as a breakdown dimension.

Read it by looking for the single biggest percentage drop between steps: that step is your conversion priority. The device breakdown frequently reveals that the problem is really a mobile problem. Fixing the worst step first beats polishing the whole journey.

Report 2: path exploration, or what visitors do next

Business question: we invested in the new homepage, so where do people actually go from it?

Choose Path exploration. Set the starting point to a page (switch the node type from event name to page title or page path) and watch the tree of next steps unfold. You will often find that pages you consider vital are barely visited, while a pricing page or an obscure FAQ carries far more traffic than the navigation suggests it should.

The reverse version is even more useful. Click Start over, set an ending point instead, and choose your enquiry key event. Now you are looking at the last pages people saw before contacting you. Those pages deserve your strongest proof, testimonials and calls to action, whatever the sitemap says their job is.

Report 3: content that earns enquiries, not just readers

Business question: the blog gets traffic, but is any of it worth the effort?

• 1. Choose Free form and set the dimension to Landing page + query string.
• 2. Add metrics: sessions, engagement rate, key events and session key event rate.
• 3. Create a segment for Organic Search using the session default channel group, so paid and email traffic do not muddy the picture.
• 4. Sort by key events, not sessions.

The table splits your content into three groups: pages that bring traffic and enquiries (write more like these), pages with traffic but no enquiries (add relevant calls to action and internal links to service pages), and pages with neither (candidates for updating or consolidating). It is a content strategy in one table.

Report 4: cohorts, or whether people come back

Business question: are we building repeat custom, or is every sale a one-off?

Choose Cohort exploration. Group users by the week of their first visit, set the return criteria to any event for general stickiness or to purchase for ecommerce, and read across each row to see how many return in the weeks that follow.

Most small-business websites show steep drop-off, and that is normal; what matters is the trend and the exceptions. If a cohort acquired during a particular campaign keeps returning at twice the usual rate, that campaign attracted better-fit customers. Weak retention overall is the strongest data-backed argument for starting an email newsletter or a remarketing list, because it proves visitors rarely come back on their own.

Report 5: segment overlap, or the truth about mobile

Business question: half our traffic is mobile, so why do the sales all look like desktop?

Choose Segment overlap and add three segments: mobile traffic, desktop traffic, and users with a key event. The Venn diagram shows immediately whether your converters skew desktop. If mobile users are half your audience but only a sliver of the overlap, you have a mobile experience problem, and combined with Report 1's device breakdown you will usually know exactly which step of the journey fails on small screens.

A practical bonus: overlapping sections can be saved as audiences, for example mobile visitors who reached the checkout but hold no purchase key event, ready for a remarketing campaign.

Make it a monthly habit

• Save each exploration with a plain-English name that states the question, not the technique.
• Explorations are private to your login by default; use the share icon to give colleagues read-only access.
• Review the funnel and content reports monthly, cohorts and paths quarterly.
• Write one sentence of action under each before closing the tab; a report that changes nothing is decoration.

Five saved explorations, checked on a schedule, will answer more real questions than any off-the-shelf dashboard. If you would like them configured for your business, with key events set up properly first, our team at Thind Global Services does exactly this.
