Running Google Ads without conversion tracking is like driving at night without headlights. You may see traffic, but you won’t know which campaigns, keywords, and ad groups are actually generating leads or sales for your Australian small business.

This guide explains how to connect Google Ads conversion tracking to your WordPress site so you can measure form submissions, phone calls, and other valuable actions, and optimise your ad spend based on real data.

What Is Google Ads Conversion Tracking?

Google Ads conversion tracking records specific actions visitors take after clicking your ads, such as:

  • Contact form submissions.
  • Phone calls from your website.
  • Newsletter sign‑ups.
  • Purchase completions (for e‑commerce).

By enabling conversion tracking, you can see which ad variations and keywords deliver the best ROI and adjust bids and budgets accordingly.

For small businesses in Australia, knowing which Google Ads campaigns drive real enquiries is essential for justifying your marketing spend and improving results.

Step 1 – Create a Conversion Action in Google Ads

To start tracking, first define what counts as a “conversion” in your Google Ads account:

  1. Log in to Google Ads.
  2. Click the tools icon (☰) in the top right corner.
  3. Go to Measurement → Conversions.
  4. Click the blue + New conversion action button.
  5. Select the conversion source (Website).
  6. Enter:
    • A descriptive name (e.g., “Contact Form Submission”).
    • Value (if applicable, e.g., fixed or dynamic value per lead).
    • Count (one or all conversions per user).
  7. Choose how you want to track the conversion (e.g., “Use a tag” or “Use Google Tag Manager”).

Google will provide a conversion tag or event snippet that you must add to your site.

Step 2 – Add the Conversion Tracking Code to WordPress

There are several ways to add the Google Ads conversion tag to your WordPress site.

Option A – Add the tag directly to your theme

If you use a theme or child theme that lets you edit header/footer code:

  1. Copy the conversion tracking code from Google Ads.
  2. Go to Appearance → Theme Editor or your theme’s custom header/footer section.
  3. Paste the code just before the closing </head> tag (or use a header/footer plugin).

Warning: Always backup your site before editing theme files.

Option B – Use Google Tag Manager (recommended)

Google Tag Manager (GTM) gives you more control and makes it easier to update tracking without touching your theme.

  1. Create a GTM account and install the GTM snippet on your WordPress site (manually or via a plugin).
  2. In GTM, create a new tag of type “Google Ads Conversion Tracking”.
  3. Paste your conversion ID and label from Google Ads.
  4. Set up a trigger (e.g., “Page View” or “Form Submission” event) and publish the container.

Using GTM means you can add, edit, or remove conversion tags without changing your WordPress theme.

Step 3 – Track Form Submissions and Phone Calls

For most small business websites, the primary conversions are contact form submissions and phone calls from the website.

Tracking form submissions

To track form submissions, you can:

  • Use GTM with a form submission trigger.
  • Use a plugin such as WPForms or Contact Form 7 that supports Google Analytics or Google Tag Manager integrations.

The goal is to fire the Google Ads conversion tag when the form success page loads or when a form‑submission event is triggered.

Tracking phone calls from the website

If you display a phone number on your site, you can track clicks as conversions by using:

  • Google Ads call‑extensions (for calls directly from ads).
  • Dynamic number insertion + conversion tracking for clicks on your website’s phone number.

For example, when someone clicks the phone number on your contact page, you can trigger a conversion event so you know that visitor came from a Google Ads campaign.

Step 4 – Verify and Test Conversion Tracking

After implementation, verify that conversions are being recorded correctly.

  1. Go to Tools → Conversions in Google Ads.
  2. Check the status of your conversion actions (look for “Active” or “Available”).
  3. Use the “Realtime” view in Google Analytics (GA4) or Google Ads to see if form submissions appear as events.
  4. Test the flow yourself: click a Google Ads or dummy ad, fill the form, and confirm the conversion fires.

Wait a few hours or days if necessary, as some conversions may not appear instantly.

Once you see test conversions appearing in your Google Ads dashboard, you know your tracking is working.

Step 5 – Use Conversion Data to Optimise Google Ads

With conversion tracking in place, you can optimise your campaigns for performance instead of impressions or clicks.

Key actions you can take:

  • Pause or reduce bids on keywords, campaigns, or ad groups that generate clicks but no conversions.
  • Increase bids on converters to get more high‑quality leads.
  • Use conversion‑based bidding strategies (e.g., “Maximise conversions” or “Target CPA”) once you have enough conversion data.
  • Test different ad copy and landing pages and choose the versions that drive the most conversions.

For Australian small businesses, this data‑driven approach helps you get more value from your Google Ads spend and improves overall ROI.
