As browser privacy updates like Safari’s ITP and the phase-out of third-party cookies make traditional tracking less reliable, server-side tracking has become the gold standard for Australian businesses. By moving your tracking from the user's browser to a private server, you regain control over your data, improve website speed, and ensure your marketing attribution remains accurate.
Why Server-Side Tracking Matters
Traditional 'client-side' tracking happens in the user’s browser, where it is easily blocked by ad blockers or restricted by privacy settings. Server-side tracking acts as a secure intermediary. Data is sent from your website to your own server, which then cleans, processes, and forwards it to platforms like Google Ads or Facebook. This results in better data for your campaigns and faster load times for your customers.---
Prerequisites
Before you begin, ensure you have the following ready:- Google Tag Manager (GTM) Account: You must have an existing Web Container installed on your site.
- Google Cloud Platform (GCP) or Stape account: To host your tagging server.
- Domain Access: Ability to create a DNS record (e.g.,
metrics.yourbusiness.com.au). - Administrative Access: To your website and marketing platforms.

Step 1: Create a Server Container in GTM
Log in to your Google Tag Manager account. Click on Admin > Container > + (Create Container).- Container Name: Use something clear like "[Business Name] Server Side".
- Target Platform: Select Server.
- Screenshot Description: You will see a pop-up asking how to set up your tagging server. Choose "Automatically provision tagging server" if you want a quick setup via Google Cloud.
Step 2: Set Up Your Tagging Server
Once you click "Automatically provision," Google will ask you to create a Billing Account for Google Cloud.Tip: Google Cloud offers a free tier, but for most Australian small businesses, the cost is usually around $10–$15 AUD per month depending on traffic.
Follow the prompts to select your billing account and click Create. It will take about 5–10 minutes for Google to provision your server. Once finished, you will see your Default Tagging Server URL (usually ending in .appspot.com).
Step 3: Configure a Custom Domain
Using the default.appspot.com URL is okay for testing, but for maximum effectiveness, you need a custom subdomain (e.g., tracking.yourdomain.com.au). This ensures your tracking is "first-party," making it much harder for browsers to block.
- In GTM Server Container, go to Admin > Container Settings.
- Click Add URL and enter your chosen subdomain.
- Go to your domain registrar (e.g., GoDaddy, VentraIP) and add an A record or CNAME record as specified in the GTM setup instructions.
Step 4: Update Your Web Container Settings
Now, go back to your Web Container (the one already on your website).- Go to Admin > Container Settings.
- Find the field labeled Tagging Server URL.
- Paste your new custom subdomain URL here.
- Click Save.
Step 5: Create a "GA4 Client" in the Server Container
In your Server Container, navigate to Clients. By default, Google Analytics 4 (GA4) should already be listed. A "Client" is what listens for incoming data from your website. Ensure the GA4 client is active; this will serve as the bridge for most of your marketing data.Step 6: Send Data from Web to Server
In your Web Container, open your GA4 Configuration tag (or the Google Tag).- Under Configuration Settings, add a parameter:
server_container_url. - Set the value to your custom subdomain (e.g.,
https://tracking.yourdomain.com.au). - Save and Publish the Web Container.
Step 7: Create Server-Side Tags
Now, back in the Server Container, you need to tell the server where to send the data it receives.- Go to Tags > New.
- Select Google Analytics: GA4.
- Set the Event Name to
{{Event Name}}. - Under Triggering, select All Events (where Client Name equals GA4).
Step 8: Implement the Facebook (Meta) Conversions API
One of the biggest benefits for Australian retailers is the Meta Conversions API (CAPI).- In the Server Container, search the Community Template Gallery for the official Facebook Conversions API tag.
- Enter your Pixel ID and API Access Token (generated in Facebook Events Manager).
- Set the trigger to fire on all events coming from the GA4 client.
Step 9: Preview and Debug
Click Preview in both your Web Container and your Server Container.- Web Preview: Open your website and perform an action (like a page view).
- Server Preview: You should see the incoming request appear in the summary. Click on it to see if the tags (GA4, Facebook) fired successfully.
- Screenshot Description: You should see a split-screen view. The left sidebar shows events like "page_view", and the main window shows "Tags Fired" with green checkmarks.
Step 10: Publish Your Changes
Once you have verified that data is flowing from the Browser -> Server -> Marketing Platform, click Submit and Publish in both containers.---
Pro Tips for Success
- Consolidate Tags: Use the GA4 stream as the primary data source for all server-side tags to reduce the number of scripts running on your site.
- Monitor Google Cloud Costs: Check your GCP console regularly. For very high-traffic sites, you may need to increase your server instances.
- Use First-Party Cookies: Ensure your custom domain is on the same root domain as your website to enable HTTP-only cookies.
Common Mistakes to Avoid
- Forgetting DNS Records: If you don't map your subdomain correctly, the server won't receive any data.
- Double Tagging: Be careful not to fire the same tag (e.g., Facebook Pixel) from both the browser and the server simultaneously without proper deduplication, as this will double-count your conversions.
- Missing ABN Verification: When setting up Google Cloud billing, ensure your business details match your ABN records for tax purposes in Australia.
Troubleshooting
- No data in Server Preview: Check if your
server_container_urlin the Web Container has any typos or is missing thehttps://. - 404 Errors: This usually means the tagging server hasn't finished provisioning or the DNS hasn't propagated. Wait 24 hours for DNS changes to take effect.
- Permissions Issues: Ensure the email address used for GTM has 'Editor' or 'Owner' permissions on the Google Cloud Project.
