Google Analytics 4 for SEO: How to Track Your Organic Performance

Most Melbourne business owners set up Google Analytics and then never look at it. Or they check total website visitors and nothing else. That's missing the point. GA4 answers the only SEO question that actually matters for a business: is this organic traffic turning into customers? GA4 data also feeds back into keyword research — it shows exactly which queries and pages are already working.

Setting Up GA4 for SEO Tracking

Step 1: Create a GA4 Property

Go to analytics.google.com. Click Admin > Create Property. Choose GA4. Follow the setup wizard. If you're on WordPress, install the 'Site Kit by Google' plugin — it handles GA4 and Search Console setup simultaneously and verifies both with a single step. If you're on Shopify, use the built-in Google channel or install GA4 via the Google and YouTube app.

Step 2: Set Up Conversion Events

GA4 calls them 'Conversion events' rather than Goals (the old Universal Analytics term). These are the actions that matter for your business. Common conversion events for Melbourne local businesses:

• Phone number click (mobile)
• Contact form submission
• Booking confirmed
• Free audit request submitted
• Directions request (from your Google Maps link)

Mark each as a Conversion in Admin > Events > Toggle on 'Mark as conversion.' Without this, GA4 can't tell you which traffic is actually valuable.

Step 3: Connect to Google Search Console

In GA4: Admin > Product Links > Search Console links. Connect your Search Console property. This adds a 'Google organic search traffic' section under Reports > Acquisition. Here you can see which search queries drove traffic — the one piece of data GA4 can't produce on its own.

The GA4 Reports That Matter for SEO

Traffic Acquisition Report

Reports > Acquisition > Traffic Acquisition. This shows total sessions by channel. Look for 'Organic Search' in the Default Channel Group column. What to track monthly:

• Organic search sessions — is it growing month on month?
• Organic search conversions — is organic traffic producing valuable actions?
• Organic search vs other channels — is organic's share of total traffic growing?

Landing Pages Report

Reports > Engagement > Landing Pages. Add a secondary dimension: 'Session default channel group.' Filter to show only Organic Search sessions. This shows you exactly which pages organic visitors are landing on. Your highest-traffic organic landing pages are your current top-ranking pages — these deserve ongoing maintenance and improvement. Your important pages with zero organic landing sessions have an SEO problem. They're either not ranking or not being clicked.

Conversions by Landing Page

Create an Exploration (Explore tab) with a segment for organic search sessions, dimension set to landing page, and metric set to conversions. This shows which organic landing pages produce conversions. This is the report that connects SEO work to business outcomes. A page with high organic traffic but zero conversions either attracts the wrong audience (wrong keywords) or fails to convert the right audience (CTA or page design problem).

Key SEO Metrics in GA4 and What They Mean

Using GA4 to Identify SEO Opportunities

Find Pages That Need On-Page Work

Filter Landing Pages to organic search. Look for pages with:

• High impressions in Search Console but low GA4 traffic — title tag problem. Google shows the page but people don't click.
• High GA4 traffic but low engagement rate — wrong intent match or poor page quality. People arrive and leave.
• High engagement but zero conversions — good content, weak CTA or wrong audience.

Find Keywords to Target

In the Search Console > Queries report within GA4, look for queries in positions 4 to 10 with decent impressions — these are close to page one, and an improvement push can move them. Also look for queries generating impressions but zero clicks — CTR is 0, which means a better title tag produces more traffic from pages that already rank.

This feeds back into keyword research — your GSC data shows what you're already appearing for, not just what you're trying to target.

The GA4 and Search Console Combination

Use GA4 and Search Console together. They answer different questions.

The complete SEO picture: Search Console tells you which keywords drive traffic. GA4 tells you whether that traffic is valuable. Neither alone is sufficient.

Frequently Asked Questions

How do I see my organic traffic history in GA4?

Reports > Acquisition > Traffic Acquisition > Channel Group = Organic Search. Set your date range at the top right. Click 'Compare' to add a second date range for month-on-month or year-on-year comparisons.

My GA4 shows less traffic than Google Analytics used to. Why?

GA4 counts sessions differently from Universal Analytics. GA4 uses event-based tracking while UA used session-based tracking. Some traffic that counted in UA doesn't count in GA4 due to stricter session boundary rules. The difference is usually 10 to 20%. Don't panic — the trends are comparable even if absolute numbers are lower.

How do I track phone calls in GA4?

If you have a click-to-call button on your site, mark phone number clicks as a conversion event. Use Google Tag Manager to fire a 'phone_call_click' event when the tel: link is clicked. Then mark that event as a Conversion in GA4. This tracks mobile visitors who tap your phone number directly — the most common conversion action for local businesses.
