If you’re running Google Ads without conversion tracking, you’re basically flying blind. You might see clicks and impressions, but you have no idea which ads are actually making you money. Setting up conversion tracking correctly ensures you capture every valuable action—without losing data along the way.
Here’s how to do it step by step.
Why Conversion Tracking Matters
Conversion tracking tells you what’s working and what’s wasting money. Whether you’re aiming for purchases, lead form submissions, or phone calls, this data is the backbone of bidding strategies, ad optimizations, and ROI reporting.
Without it, you risk:
-
Overinvesting in underperforming keywords
-
Missing out on high-value audiences
-
Making budget decisions based on guesswork
Step 1: Choose the Right Conversion Actions
Before touching Google Ads settings, decide which actions truly matter for your business.
Common e-commerce conversion actions include:
-
Completed purchases
-
Add-to-cart events
-
Newsletter sign-ups
-
First-time account registrations
For service-based businesses, it might be:
-
Contact form submissions
-
Scheduled calls or appointments
The more specific your actions, the more precise your optimizations will be.
Step 2: Install the Global Site Tag (gtag.js) or Google Tag Manager
For most advertisers, there are two main ways to implement tracking:
-
Directly with Global Site Tag – Add the Google Ads gtag.js snippet to every page of your website.
-
Through Google Tag Manager (GTM) – More flexible and easier to manage, especially if you run campaigns across multiple platforms.
If you’re already running Google Analytics 4, link it with Google Ads so you can import conversions without duplicate counting.
Step 3: Set Up Conversion Tracking in Google Ads
Once your tag is ready:
-
Go to Tools & Settings > Conversions in Google Ads.
-
Click New Conversion Action and choose the type (Website, App, Phone Calls, Import).
-
Enter your conversion details—name, value, count type, and attribution model.
-
Choose whether to track all conversions or unique conversions per user.
Tip: For purchases, use transaction-specific values instead of static amounts to get more accurate ROI reporting.
Step 4: Verify Your Setup
The fastest way to confirm tracking is working:
-
Use Google Tag Assistant (or Tag Assistant Companion in Chrome)
-
Trigger a test conversion (e.g., make a small purchase)
-
Check if the event is firing in Google Ads within 24 hours
Step 5: Avoid Common Data Loss Mistakes
Many advertisers unknowingly lose conversion data because of:
-
Not enabling enhanced conversions – This captures hashed customer data for more accurate reporting.
-
Cookie consent pop-ups blocking scripts – Use consent mode to maintain tracking while respecting privacy laws.
-
Incorrect page reloads after payment – Always place conversion tags on “thank you” or confirmation pages.
Step 6: Connect Google Ads with GA4 for Deeper Insights
Google Analytics 4 offers event-based tracking that pairs perfectly with Google Ads. Once linked, you can:
-
See user paths before and after the ad click
-
Attribute conversions across devices
-
Identify top-converting channels and audiences
💡 Pro Tip: If you manage multiple ad channels (Google, Meta, TikTok) and want a single place to monitor conversion performance, AdsPolar makes it easy. It integrates with all major platforms, pulls data into one dashboard, and uses AI alerts to catch anomalies in real time—helping you avoid costly tracking errors.
