Universal Analytics retired in 2023. Three years later, most UK business owners still haven't adapted to GA4, either because it hasn't been set up correctly, or because the interface feels impenetrable.
That's a problem. Without reliable analytics, you can't tell what marketing is working. You're making decisions on vibes.
This is a plain-English GA4 guide for UK business owners who don't want to become analysts, just want to know what's happening on their website.
Why GA4 feels harder than Universal Analytics
Universal Analytics treated "pageviews" and "sessions" as the foundation. GA4 treats events as the foundation. Every interaction is an event.
That shift is what broke most people's workflows. But once you get it, GA4 is more flexible and more accurate. The trick is setting up the events that matter to your business.
Step 1: Install GA4 properly
Three ways, in order of preference:
- Google Tag Manager (GTM) — the professional choice. Install GTM once, then deploy GA4 and all future tags through it without touching the site code.
- Native integration — WordPress (via plugins like Site Kit), Shopify, Framer, and Webflow all have one-click GA4 installation.
- Hard-coded tag — paste the GA4 snippet into your site's head. Works but means every change needs a developer.
Verify installation with the Google Tag Assistant Chrome extension.
Step 2: Configure UK GDPR compliance
Before tracking anyone, you need:
- Cookie consent banner that blocks GA4 until the user opts in.
- Consent Mode v2 — a GA4 feature that respects consent choices and still gives you partial data for users who decline.
- Anonymise IP addresses (GA4 does this by default).
- Privacy policy mentioning Google Analytics and UK GDPR.
Cookie tools: CookieYes, Cookiebot, or Complianz for WordPress.
Step 3: Set up the 6 events every UK business should track
Out of the box, GA4 tracks pageviews, scrolls, outbound clicks, video plays, file downloads, and site search. On top of that, every UK business should add:
- Form submission — every contact form, quote request, or booking. Most important event.
- Phone click — clicks on tel: links. Often undercounted.
- Email click — clicks on mailto: links.
- Book a meeting — if you use Calendly or similar.
- Newsletter signup — separate from contact form.
- Purchase or service enquiry converted.
Set these up as custom events in GTM. Then mark them as conversions in GA4.
Step 4: Link Google Ads and Search Console
Two free integrations that turn GA4 from "nice dashboard" into "marketing decision tool":
- Google Ads — Admin → Product Links → Google Ads.
- Search Console — Admin → Product Links → Search Console.
Skip these and you're flying half blind.
Step 5: The 5 reports that actually matter
GA4 has dozens of reports. Ignore most. Check these weekly:
1. Acquisition → Traffic Acquisition — where your visitors came from.
2. Engagement → Pages and Screens — your most-viewed pages.
3. Engagement → Events — are your conversion events firing?
4. Monetisation → Ecommerce (if relevant) — revenue by channel, product, campaign.
5. User → Tech → Device Category — mobile vs desktop split.
Ignore: Realtime, User Attributes, most Explore reports unless you're an analyst.
Step 6: Set up monthly reporting
- Create a one-page monthly report with:
- Sessions this month vs last month
- Top 5 traffic sources
- Top 5 landing pages
- Total conversions and conversion rate
- Top 3 pages driving conversions
- One observation and one action
Do this in Google Sheets or Looker Studio (free from Google, connects to GA4).
Common GA4 mistakes
- No conversions set up. Without conversion events, GA4 is just a traffic counter.
- Ignoring GDPR consent. Tracking users without consent risks £17.5M ICO fines.
- Trusting bounce rate. GA4 uses "engaged sessions." Check engagement rate instead.
- Chasing vanity metrics. Sessions are meaningless without conversions.
- Not linking Search Console. You're missing 80% of your SEO picture.
Frequently Asked Questions
Do I need GA4 if my website is small? Yes. Any website running marketing or collecting leads needs to measure what's working.
Can I still use Universal Analytics data? Historical UA data is viewable until July 2026. After that, it's gone. Export it now.
What's the difference between a conversion and an event in GA4? Every conversion is an event. Not every event is a conversion.
Should I use GA4 alongside other tools? GA4 + Search Console covers 90% of needs. Add Hotjar or Microsoft Clarity (free) for heatmaps.
The bottom line
GA4 is more complex than Universal Analytics, but also more honest. Once set up properly with the right events, conversions, and integrations, it gives you the data to make real marketing decisions.
