Google formally launched Google Ads conversion tracking in the early 2000s. It is a free tool to measure meaningful actions, such as sales, sign-ups, and form downloads, that users take after viewing your ads. The tool tracks conversions and identifies the keywords or campaigns that drive results. However, it is up to you to use the tool.

How was conversion tracking before the formal launch of Google’s tracking tool?

Before Google Ads conversion tracking, marketers relied on basic URL tracking, third-party analytics, and manual data calculations. These were all manual methods for measuring ROI by analyzing server logs to count “thank you” page hits and importing data from analytics tools.

It required significant effort. However, the biggest drawback of the manual method was its inability to attribute specific conversions. For example, you can’t see which keywords or campaigns are driving clicks. It leads to less accurate data and decisions.

Google Ads conversion tracking changed the way advertisers used to track conversions. The tool has significant advantages over traditional manual tracking. The good thing is that Google kept it free to use even after advancements. If you know how to set tracking, it can answer all your queries regarding your Google ad campaigns.

How to set up Google Ads conversion tracking?

Conversion tracking tool is available in your Google Ads settings, and you only need to create a conversion action, select a tracking method (website, app, or phone), and install the Google Tag or use Google Tag Manager (GTM) to track user actions. GTM is recommended for setting up Google Ads conversion tracking to simplify the procedure.

Reduces Dependency on Developers: Change tracking scripts directly in the GTM interface.
Quick & Flexible Process: Deploy conversion tags without requiring any development work.
Easy Conversion Linker Setup: It is easy to set up the Conversion Linker tag, responsible for data accuracy.
Simplified Enhanced Conversions: Send hashed customer data in a secure and privacy-safe manner for improved measurement.
Centralized Control: Manage all your tags in place, keeping the source code clean.
Robust Testing: GTM offers Preview and Debug mode to ensure tags fire according to settings.

Why conversion tracking?

Conversion tracking isn’t an option, but a necessity. Google itself provides a free tool to track conversions and improve your ROI. Earlier, marketers relied on manual tracking methods. However, manual methods of conversion tracking weren’t reliable. For this reason, Google launched its free conversion tracking tool to help marketers achieve desired results.

Here’re the benefits of Google Ads conversion tracking:

Increased ROI: Identify which keywords or ad campaigns give the highest return on investment and allocate your ad spend to profitable keywords or ad campaigns.
Data-Driven Decision Making: Learn how users interact with your ads and make decisions on improving the ads on facts, instead of wild guesses.
Smart Bidding: Conversion tracking automates bidding that further increases the performance of ads and ROI. It also removes manual bidding drawbacks, like human errors.
Identify Profitable Channels/Platforms: You can see the channels/platforms that send valuable customers. You can also see which customers complete actions, such as purchases and sign-ups.
Identify Areas of Improvement: Conversion tracking highlights the overall performance of ad campaigns. You can see which ads need improvement and what to improve in the ads.
Track Multiple Conversion Types: Google Ads conversion tracking allows tracking multiple conversion types, such as app installations, newsletter sign-ups, and phone calls. It captures the complete user journey.
Competitive Advantage: An accurate conversion tracking setup gives a competitive advantage over others. You can see how your ads perform in different environments and improve the settings.

Considering the advantages of Google Ads conversion tracking, it won’t be an exaggeration to say that it has become indispensable for marketers. It isn’t that your ad campaigns will fail without conversion tracking, but you’ll certainly experience setbacks at the hands of your competitors. They will be better positioned than your ads and drive maximum traffic.

Let’s come back to the main topic “how to set up Google Ads conversion tracking”

The next thing to learn about Google Ads conversion tracking setup is the different ways. There are two main ways of setting up conversion tracking.

1. Client side conversion tracking
2. Server side conversion tracking

You need to learn about both ways of conversion tracking so that you understand their differences and choose the best method. For your information, server-side tracking is more reliable and popular. If you are new to Google ads conversion tracking, you need to focus on both the ways. A little mistake in settings can send your conversion tracking to nowhere, leaving you alone with puzzled data.

Client Side Conversion Tracking

It is the traditional method involving implementing tracking scripts directly in the browser (user side). It is typically done and also highly recommended via Google Tag Manager (GTM). You can set conversion tracking for both Google Ads and Meta. The process is largely manual and has serious limitations that make it less useful for accurate conversion tracking.

Steps to Set Up Client-Side Conversion Tracking (via GTM):

1. Create Conversion Action: Access your Google Ads account, enter the website URL you want to track, and define the conversions, such as sales, sign-ups, and form downloads.
2. Add Conversion Linker in GTM: Create a new tag in your GTM as Conversion Linker and set it to fire on all pages, whenever a conversion takes place.
3. Create Conversion Tag in GTM: Create a new tag and copy your Conversion Id and Conversion Label from Google Ads and paste it in the new tag.
4. Set Up Trigger: Create a trigger that fires on the conversion pages.
5. Publish Changes: Preview the settings to ensure accuracy and publish to start tracking.

Benefits & Limitations:

Simple Setup: It is easy to implement using GTM or direct code injection.
Low Latency: Browser sends data directly to the marketing platform.
Ad Blockers: Susceptible to data loss by browser restrictions and ad-blockers.
Performance: Heavy scripts can slow down page load speed.

Server-Side Conversion Tracking

It is the most popular way of setting up Google Ads conversion tracking. Not only is it easy to set up, but it also ensures data accuracy. The process involves routing the browser data to marketing platforms through a tagging server. It prevents data loss by ad-blockers and ensures data privacy.

Steps to Set Up Server-Side Conversion Tracking:

1. Create a GTM Server Container: Access your GTM account and follow the instructions to create a container.
2. Provision a Tagging Server: You can choose between positioning the server on Google Cloud Platform or deploying it on a third-party host like Stape.
3. Create a Custom Subdomain: It ensures seamless data transfer through first-party cookie usage.
4. Configure Web GTM to Send Data: Configure GA4 tags in Web GTM to send data to the new tagging server.
5. Set Up Server GTM Container:
Create a GA4 client to receive data.
Create a Conversion Linker tag to fire all pages.
Create a Google Ads Conversion Tracking tag to send data to your account.
6. Validate and Publish: Preview the settings to ensure accuracy and publish to start tracking.

Benefits & Limitations:

Improved Data Accuracy: Conversion tracking is free from ad-blockers, browser restrictions, and privacy settings.
Faster Website Performance: Unlike client-side settings, it doesn’t use JS tags that slow down page downloads.
Higher Technical Complexity: Requires a good understanding of web development.
Reduced Client-Side Data: It is difficult to track real-time user behavior with server-side conversion tracking.
Extra Costs: Hosting and running a server-side container can increase your marketing budget.

Common Issues with Google Ads Conversion Tracking

A professional setup is highly recommended to ensure proper Google Ads conversion tracking. If you’re new to Google Ads, consider hiring a professional to set up your conversion tracking. If you still want to do it on your own, look for common issues. An unprofessional setup can lead to any of the following problems.

Tags Not Firing: It is a classic example of an improper setting. Improper tags or triggers may lead to unresponsive tags.
Duplicate Conversions: It is also due to improper tag settings. They are fired multiple times, for example, during a refresh of the confirmation page.
Missing Conversion Linker: If you miss it, you will miss tracking the user journey across multiple domains and regret it later.
Misconfigured Consent Mode: Respect ad-blockers and privacy settings by configuring the consent mode or lose data.
Missing GCLID: Google can link clicks to conversions only when the Google Click Identifier is properly set.
Using Secondary Conversions: You’ve wrongly set the action to secondary, leading to failure of Smart Bidding.
No Values/Revenue Data: The issue could be in tag implementation, Data Layer configuration, JS redirects, or incorrect parameter format.
Data Discrepancies (GA4 vs. Google Ads): It happens when there is a difference in their attribution models, reporting time, and tracking mechanism.
Untracked Conversions: Losing valuable data, especially phone calls and offline actions, can cost you dearly in terms of tracking. You need to look into the conversion settings.
Unpublished Changes: It is most likely due to a technical reason, such as browser glitches or a session timeout.¹

Only an expert can help set Google Ads conversion tracking on your website.
