Google Analytics 4 is free, powerful and confusing in equal measure. Many business sites have it installed, yet the data is half-configured: internal visits are counted, key actions are not tracked, and nobody quite trusts the numbers. A tidy setup takes a few hours and makes every later decision easier. Here is a sensible order to do it in.
Create the account and property properly
Use a company-owned Google account, not a personal one belonging to a freelancer or a former employee. Create an Analytics account for your business, then a property for the website. Set the correct reporting time zone and currency, because these affect how data is grouped.
Add a web data stream for your site's domain. Make a note of the measurement ID; you will need it for installation.
Give access to other people through user management with the lowest permission level they need. Avoid sharing a single login.
Install the tracking code
There are three common routes:
- Google Tag Manager, which is the most flexible option and lets you add or change tracking without editing the site code each time.
- A platform integration, such as the built-in options in Shopify or plugins for WordPress.
- Direct installation of the Google tag in the site's code, suitable for simple custom sites.
Choose one method only. Installing through two routes at once double-counts visits, a surprisingly common mistake.
Check enhanced measurement
GA4 can automatically track scrolls, outbound clicks, site search, video engagement and file downloads. Review these settings in the data stream. Keep what is useful and switch off anything that creates noise. If your site search uses an unusual parameter, add it so searches are captured.
Define your key events
Out of the box, GA4 does not know what success means for your business. Decide which actions matter, such as:
- A contact or quote form submitted successfully.
- A booking confirmed.
- A phone number or email link clicked.
- A purchase completed, with value.
Create events for these, ideally triggered by a confirmation page or a success message rather than a button click alone. Then mark them as key events so they appear in conversion reports.
Clean up the data
Exclude internal traffic
Define your office and team IP addresses as internal traffic and activate the filter. Remote teams on changing connections may need a different approach, such as a browser extension or a parameter-based exclusion.
Exclude unwanted referrals
Payment providers and booking tools sometimes appear as referral sources because the visitor leaves and returns. Add them to the unwanted referrals list.
Extend data retention
The default retention period for detailed exploration data is short. Increase it to the maximum available in the settings so you can analyse longer trends.
Handle consent and privacy
In many regions, including the UK and European Union, you need consent before setting analytics cookies. Use a consent management tool and configure consent mode so GA4 respects visitor choices. Update your privacy notice to explain what you collect. A related guide on writing a privacy policy and cookie notice explains the basics.
Connect other tools
Link Search Console to see organic search queries alongside behaviour. Link Google Ads if you run campaigns, so conversions can be used for bidding. If you use a CRM, consider passing lead source data into it as well.
Build a few reports you will read
The standard reports are broad. Create a small number of saved reports or a simple dashboard covering traffic by channel, top landing pages, key events by source and device split. Fewer, clearer reports beat a dozen nobody opens.
FAQ
Can I keep my old Universal Analytics data?
Universal Analytics has stopped processing data. If you exported historical reports earlier, keep them separately for comparison. GA4 data starts from its own setup date.
Why does GA4 show fewer users than my other tools?
Consent choices, ad blockers and different counting methods all cause gaps. Focus on trends and relative performance rather than matching totals exactly.
Do I need Google Tag Manager?
Not strictly, but it makes tracking changes much easier over time, especially when marketing needs evolve.
