How to Set Up Google Ads Conversion Tracking

By Corey Frankosky · Last Updated August 6, 2026

Google Ads conversion tracking is how you measure what happens after someone clicks your ad. It shows you which ads, keywords, and campaigns drive purchases, form submissions, phone calls, and sign-ups, so you can put your budget where it actually works. Without conversion tracking, you are running ads on guesswork and you have no reliable way to know what is producing results. In this guide you will set up Google Ads conversion tracking the right way, from creating conversion actions to installing tags and testing that everything fires. Follow the steps in order and you will have accurate data feeding your campaigns.

1What You Need Before You Start

Before you touch any code, get three things in place. You need administrative access to your Google Ads account, access to your website, and a clear list of the actions you want to track. When these are ready from the start, you avoid the stops and restarts that make setup take longer than it should.

Confirm that whoever is handling the setup has admin permissions on the Google Ads account. You also need admin access to your website so you can add tracking code directly, or you need to coordinate with the developer who does. If you plan to use Google Tag Manager, it acts as a central hub for your tags, so you can add, update, or remove tracking code without editing your website every time.

Now define what counts as a conversion for your business. Conversion tracking works best when you are specific about what matters. A local restaurant might track online reservations or catering inquiries. An e-commerce store focuses on completed purchases and email sign-ups. A B2B software company prioritizes demo requests or resource downloads. Identify the top three to five actions that drive your revenue and document them. Tracking everything clutters your data and makes it harder to see what is working.

Your website needs to be ready to capture the action, and that usually means a dedicated confirmation or thank-you page for each conversion. After a purchase, send customers to a page like yoursite.com/thank-you-purchase instead of the homepage. After a contact form submission, send them to yoursite.com/contact-thank-you. Those unique URLs are where your tracking fires. If those pages do not exist yet, build them before you continue. Walk through the full conversion process yourself first and check for broken links or confusing steps, because a smooth path is what makes the tracking accurate.

Question to Answer:

Which three to five actions on your website are worth the most to your business, and does each one have its own confirmation page?

2Watch: Conversion Tracking With Google Tag Manager

Here is a full walkthrough of setting up Google Ads conversion tracking with Google Tag Manager. Watch it once end to end, then use the written steps below as your reference while you build your own setup.

If you want a professional to build and manage this for you, our Google Ads management services handle conversion tracking setup as part of every account we run. If you would rather learn the full system yourself, the Google Ads course walks through it step by step.

Question to Answer:

Will you install your tags directly in your site code, or manage them through Google Tag Manager?

3Create a Conversion Action in Google Ads

A conversion action is the tracked interaction you care about, and each one generates a unique piece of code that connects the action on your site back to your campaigns. Here is how to create one.

1. Open the Conversions section. Log into Google Ads, go to the Tools & Settings menu in the top-right corner, select Measurement, and click Conversions.
2. Add a new action. You will see any existing conversion actions listed. Click the blue plus button and select Website as your conversion source.
3. Choose how to install the tag. For most people, the Add conversion tracking tag yourself option is the right choice, especially if you manage your own site code or use Google Tag Manager. This gives you full control over where the code is placed.
4. Define the conversion type. Decide what you are tracking, such as a visit to a thank-you page, a form submission, or a button click.

Once the action is created, Google gives you the tracking code you will install later. First, you need to configure the settings correctly.

Question to Answer:

Have you named your conversion source and confirmed you are installing the tag yourself rather than through a Google Analytics import?

4Configure Your Conversion Action Settings

The settings you choose here decide how your data is counted, valued, and fed into automated bidding. Get them right and your campaigns optimize toward the actions that actually matter.

• Conversion name: Use a clear, specific name like "Contact Form Submissions" or "Checkout Completed" instead of "Conversion 1." You will thank yourself when you are managing several actions later.
• Category: Pick the category that matches the goal. Google offers over 12 categories grouped into Sales, Leads, and other types. Use Purchase for e-commerce transactions, Lead for quote requests or contact forms, and Sign-up for newsletter subscriptions. The category helps Google's bidding understand the value of each conversion.
• Value: Assigning a value improves optimization, especially with strategies like Maximize Conversion Value. You can use no value, a fixed value, or a dynamic value. Lead generation businesses often assign a static value such as $50.00 per lead, while e-commerce sites pass a dynamic value that reflects the actual purchase amount.
• Count: Choose One for actions like form submissions or sign-ups, where a repeat submission from the same person should not inflate your numbers. Choose Every for product purchases, where each transaction is worth counting.
• Conversion window: This is the time frame during which a conversion is credited to an ad click, and it ranges from 7 to 90 days. If you have a longer sales cycle, the 90-day window gives you a more complete picture of ad performance.
• Attribution model: This decides how credit is split across multiple ad interactions. The Data-driven model is Google's recommended choice because it uses machine learning to assign credit based on each touchpoint's role. Last-click gives all credit to the final interaction and can work for short sales cycles.
• Action optimization: This marks a conversion as Primary or Secondary. Only mark actions as primary when you want them counted in the main Conversions column and used by automated bidding. Those should be your lead form submissions, phone calls, and content downloads. Secondary conversions are still tracked and appear in All conversions, but they do not drive bidding, which makes them useful for softer actions like newsletter sign-ups.

One thing to watch: if you use external call tracking software alongside Google Ads, uncheck Include in Conversions for Google Ads phone call tracking so you do not double-count the same phone leads across two systems.

Your category and value settings feed directly into which Google Ads bidding strategy can work for your account, so it is worth setting them deliberately.

Question to Answer:

Is each conversion action set to the correct count and marked primary or secondary based on whether you want bidding to optimize for it?

5Install the Global Site Tag Method

The Global Site Tag method places Google's tracking code directly into your website's HTML. It is a good fit for smaller sites where you have straightforward access to the code.

In your Google Ads account, go to Tools & Settings and select Conversions. Click the conversion action you created, then choose Install the tag yourself. Google gives you two pieces of code.

• The Global Site Tag: Place this in the <head> section of every page on your site, right after the opening <head> tag. It loads Google's tracking library and handles the baseline tracking across your site. You add it once and it works for all of your conversion actions.
• The Event Snippet: This goes only on the pages where the conversion happens. If you track form submissions, add it to your thank-you page. If you track purchases, add it to your order confirmation page. The snippet carries your unique Conversion ID and Conversion Label, which tell Google exactly what action was completed.

Make sure the Global Site Tag appears before any other Google tracking codes on the page. That keeps your data clean and avoids conflicts with other tracking systems. If editing your HTML by hand is not appealing, the Google Tag Manager method below is a better fit.

Question to Answer:

Is the Global Site Tag on every page and the Event Snippet only on your confirmation pages?

6Install With Google Tag Manager

Google Tag Manager lets you install one container and manage every tag from a dashboard instead of hard-coding multiple snippets into your site. Create a Tag Manager account, set up a container for your website, then add the container code by placing one snippet in the <head> and the other just after the opening <body> tag.

With the container in place, set up your conversion tracking:

1. Create the tag. Add a new tag and select Google Ads Conversion Tracking as the tag type.
2. Enter your IDs. Add the Conversion ID and Conversion Label from your Google Ads account. You will find both values in the Event Snippet for your conversion action.
3. Build the trigger. Create a trigger that tells the tag when to fire. For most conversions you will use a Page View trigger that activates on your thank-you or confirmation page. Target it with the exact URL or a condition like Page URL contains "thank-you."

Tag Manager also supports more advanced tracking without touching your site code. You can track button clicks, form submissions, or scroll depth. To track a form, create a Form Submission trigger that fires when someone submits a form with a specific ID or class name. Before you publish, use Tag Manager's Preview mode to confirm your tags fire correctly, then click Submit to go live.

Question to Answer:

Did you add a Conversion Linker tag firing on all pages before publishing your container?

7Global Site Tag vs. Google Tag Manager

Which method you choose comes down to how complex your site is, how technical your team is, and how much you expect your tracking to grow. Here is how the two compare.

The Global Site Tag is ideal for a smaller business with straightforward tracking needs. It is quick to implement and you do not have to learn a new tool. The trade-off is that once you are managing several tags, editing HTML by hand gets messy.

Google Tag Manager is the better choice when you use multiple tracking tools or want more control over your data. Your marketing team can make updates without pulling in a developer, new tags go live faster, and the debugging tools are strong. The setup takes more effort up front, but the long-term convenience is worth it. This is why most agencies and larger businesses centralize their tags in Tag Manager. It reduces errors and makes it easier to adjust tracking to comply with privacy regulations.

Question to Answer:

Given your site's complexity and your team's skills, which method will you actually be able to maintain over time?

8Test Your Conversion Tracking

Once your tags are installed, verify they work before you rely on the data. A few free tools make this straightforward, and using them together helps you catch problems early.

Start with Google Tag Assistant. Add your website domain, walk through your conversion process, then return to the tool to review the results. Disable ad blockers and accept cookies while you test, because both can interfere with tracking. If you use Google Tag Manager, switch to Preview mode first. It shows you exactly which tags fire on each page, which is especially helpful for events like form submissions and button clicks.

Run a full test by completing a lead form or placing a test order. These test conversions will not appear in your Google Ads account because they are not tied to a real ad click, but seeing the tags fire in your testing tools confirms the setup is technically sound. You can also check the Status column under Goals > Summary in Google Ads. It is normal for a new conversion action to read "unverified" until an actual ad click leads to a conversion.

To confirm real attribution, set up a small search campaign with a low budget, click your own ad, and complete the conversion action. That is the only way to verify Google is correctly attributing conversions to your ads. If you want to keep that test budget efficient, a tight negative keyword list keeps your ad from showing on irrelevant searches.

Question to Answer:

Have you seen your tag fire in Tag Assistant or Preview mode, and confirmed real attribution with an actual ad click?

9Fix Common Tracking Problems

Most tracking issues fall into a few predictable categories, and each has a clear fix.

Tags not firing is the most frequent problem. If Tag Assistant detects no activity, review your triggers in Google Tag Manager and make sure the conditions match the real URLs or form elements on your site. A trigger set for "thank-you.html" will not fire if your confirmation page is actually "order-complete.php." Check the browser console for JavaScript errors too, since those can block tags from firing, and Content Security Policy errors are a common culprit.

Missing conversion data in Google Ads has a few causes. Allow up to 24 hours for Google to process data after setup. Confirm that auto-tagging is enabled under Account Settings > Preferences, because without it Google cannot link ad clicks to conversions. If you use Google Tag Manager, verify the Conversion Linker tag is in place and firing on all pages.

Duplicate conversions usually trace back to counting settings. If you chose "Every" instead of "One," your numbers can inflate. Switch to "One" for most actions like purchases and lead form submissions.

Missing GCLID parameters break attribution. After you click your own ad, check whether the GCLID parameter stays in the URL as you move through your site. If it disappears, your website is stripping the parameter during a redirect or form submission, and your developer needs to preserve it throughout the journey. If you serve traffic in the EU, UK, or Switzerland, use Tag Manager's Preview mode to confirm consent states update correctly based on user cookie preferences.

Question to Answer:

Is auto-tagging turned on, and does the GCLID parameter survive as a user moves from your ad to your confirmation page?
