Most Australian businesses have GA4 installed but not configured — meaning they are collecting data but not measuring what matters. This guide covers what to set up, what to ignore, and how to make GA4 actually useful for lead generation and ecommerce.

Google Analytics 4 replaced Universal Analytics in July 2023. Most Australian businesses have the GA4 tracking code installed — but having it installed and having it configured correctly are very different things. A misconfigured GA4 can give you confidence in data that is wrong, which is worse than having no data at all.
This guide covers what actually needs to be configured in GA4 for an Australian business website, what common mistakes to avoid, and how to make the data genuinely useful for business decisions.
Universal Analytics stopped processing hits in July 2023. If your website was tracking conversions, audience data, or campaign performance in Universal Analytics, that historical data is no longer being updated and will eventually be deleted by Google.
GA4 is not a direct replacement — it is a substantially different platform with a different data model (event-based rather than session-based), different attribution, and different reporting. Businesses that installed GA4 as a direct copy of their UA setup and walked away are likely collecting incomplete or inaccurate data.
For Australian businesses investing in SEO, Google Ads, or content marketing, accurate measurement is foundational. Poor measurement leads to decisions like: pausing the SEO campaign that is actually working, increasing spend on the channel that is generating vanity metrics, or incorrectly attributing leads to the wrong source.
A GA4 property should have one data stream per platform: one for your website, one for your iOS app (if applicable), one for your Android app (if applicable).
For most Australian business websites, you have a single web data stream. Verify:
By default, GA4 retains event data for 2 months. For any meaningful year-over-year analysis, change this to 14 months in Admin → Data Settings → Data Retention. Do this immediately — it only applies to data collected after the change, so you cannot retroactively extend retention.
If you or your team visit your own website regularly, those visits inflate your traffic numbers and distort behaviour metrics. Create an internal traffic filter in Admin → Data Streams → Configure Tag Settings → Define Internal Traffic.
Add your office IP address, and any VPN or remote work IP addresses your team uses regularly. This filters your traffic out of reports without losing the raw data.
GA4 automatically excludes some payment gateways from referral traffic (to prevent Stripe, PayPal, or eWAY from appearing as a traffic source when customers return from completing a payment). Verify that any payment gateway you use is on the exclusion list.
For Australian ecommerce sites using eWAY, Windcave, or Fatzebra, check that these are included in referral exclusions if they are causing sessions to appear as referral traffic.
This is the most important configuration step for Australian businesses — and the one most commonly skipped.
A conversion event is any action that represents meaningful business value: a form submission, a phone call click, a quote request, an appointment booked, a product purchased. Without conversion events configured, GA4 can tell you that 1,200 people visited your site last month but not how many became leads.

GA4's enhanced measurement tracks outbound clicks; ensure your phone number is a tel: link.purchase event — this should be implemented via your ecommerce platform's native GA4 integration (Shopify or WooCommerce both have this)Track 3–5 meaningful events, not 15. Every event you mark as a conversion affects your reports and your Google Ads Smart Bidding if you connect GA4 to Ads. Tracking "scroll depth 25%" as a conversion event creates noise; tracking "form submitted" creates insight.
Connecting GA4 to Google Search Console unlocks the Queries report in GA4 — showing which search queries drove sessions and which pages they landed on. This is the closest GA4 gets to the keyword data that Google encrypts in standard organic traffic reporting.
To connect: Admin → Property Settings → Product Links → Search Console Links.
You need to be an admin of both the GA4 property and the Search Console property for the same domain.
If you run Google Ads, linking GA4 to your Ads account enables:
For Australian businesses running Google Ads, this link is essential for campaign optimisation.
GA4's interface is different from Universal Analytics. Here are the reports most useful for Australian business websites:
Shows where your sessions are coming from: Organic Search, Direct, Referral, Paid Search, Organic Social. The channel breakdown lets you understand which sources are generating meaningful traffic.
What to look for: What percentage of your traffic is Organic Search? Is it growing over time? If you are investing in SEO, you should see organic traffic trend upward over 6–12 months.
Shows your conversion events by count and which sessions produced them. Filter by traffic source to see which channels are generating actual leads.
What to look for: Which traffic source has the highest conversion rate? For most Brisbane professional services businesses, Organic Search converts better than any paid channel over time.
Shows which pages users first land on, with engagement metrics. Useful for identifying which pages are driving traffic but not converting.
What to look for: Pages with high sessions and low conversion rates are candidates for conversion rate optimisation.
The custom exploration tool lets you build reports GA4's default interface does not show. Useful for: user journey analysis, cohort analysis, funnel analysis.
Your office IP visiting the site multiple times a day skews session counts, bounce rates, and time-on-site. Filter it out from day one.
GA4 allows you to mark any event as a conversion with a toggle. Resist the urge to mark every enhanced measurement event (scrolls, outbound clicks, video plays) as a conversion. Reserve conversion status for events that represent genuine business value.
GA4 uses an event-based data model and data-driven attribution. Universal Analytics used a session-based model with last-click attribution. The numbers will differ — sometimes significantly. Do not compare them directly.
The 2-month default means that 3 months from now, your oldest data is deleted. Set retention to 14 months on day one.
Hard-coding GA4 tags directly into your website's HTML makes future changes harder. Using Google Tag Manager gives you a centralised place to manage all tracking tags — GA4, Meta Pixel, LinkedIn Insight, Google Ads — without editing code each time.
For Next.js sites, use @next/third-parties for GA4 and GTM loading to minimise INP impact. See: Website Performance & Core Web Vitals guide
Shopify and WooCommerce both have native GA4 integrations that implement the standard ecommerce events (view_item, add_to_cart, begin_checkout, purchase) automatically. Enable these integrations rather than implementing manually.

No — but GTM makes GA4 easier to manage, and it provides a centralised place for all your tags. For most Australian businesses, the combination of GTM + GA4 is better than GA4 alone because future tag changes do not require code deployments.
Not directly — Google encrypts most organic search query data. Connecting GA4 to Search Console unlocks the Queries report, which shows the search terms driving sessions to your site. This is the closest available substitute for the keyword data Universal Analytics used to show.
Conversion data is useful from day one if conversions are configured correctly. Trend analysis (month-over-month, year-over-year comparisons) requires at least 3–6 months of data. Set data retention to 14 months immediately to preserve data for annual comparisons.
Google retired Universal Analytics in July 2023 — it stopped processing new data at that point. The historical data in UA remains accessible until Google deletes it (announced but with no definitive final date). Export any historical data you want to retain before it is removed.
Use GA4's Real-time report — load your website in a separate browser tab and verify a session appears in Real-time within 30 seconds. For conversion testing, submit a test form and verify the conversion event appears in Real-time. For production verification, use GA4 DebugView with the Google Analytics Debugger Chrome extension.
