Google ads conversion tracking with Google Tag Manager (2025)
Step 1: Create Conversion Actions in Google Ads
Before you can track conversions using Google Tag Manager (GTM), you need to set up conversion actions in your Google Ads account. These actions represent specific user activities - like purchases, form submissions, or sign-ups - that Google Ads monitors to evaluate your campaign's performance and return on investment (ROI).
Start by navigating to the "Goals" icon in Google Ads, then select "Conversions" under the "Summary" section. Here, you can view existing conversion actions or create new ones.
To set up a new website conversion action, click on "New conversion action" and choose "Website." Next, select the conversion category that aligns with your objective. Google Ads provides options like "Submit lead form", "Purchase", or "Sign-up." Be sure to name the action in a way that clearly reflects the user activity being tracked.
Selecting the right category is essential since it directly impacts how Google Ads optimizes your campaigns and reports performance metrics.
If you're tracking eCommerce sales, set the conversion value to reflect the actual sale amount. For lead generation, assign a fixed value that represents the importance of each lead. These values play a key role in calculating ROI and guiding your bidding strategies.
You'll also need to configure how conversions are counted. Choose "Every" if you want to track all occurrences of an action, such as multiple purchases from the same user. Alternatively, select "One" to track only the first instance of an action per user - this is often used for actions like form submissions. Pick the setting that best suits your business goals and reporting needs. Once this is done, you can retrieve the identifiers needed for GTM setup.
After creating your conversion action, Google Ads will provide a Conversion ID and Conversion Label - unique codes required for setting up the corresponding tag in GTM. You can find these under the "Use Google Tag Manager" tab. Keep these handy, as you'll need them later.
At first, the status of your conversion action will appear as "Inactive." This is completely normal and will change once you start sending conversion data through GTM.
For better organization, especially in multinational campaigns, it's helpful to use clear and consistent naming conventions. For example, at Senwired, we use names like "Checkout_Purchase_USD" for eCommerce transactions or "Contact_Form_Submit" for lead forms. These descriptive names make reporting, troubleshooting, and scaling much easier as your campaigns grow.
Once you’ve saved your Conversion ID and Label, you’re ready to move on to configuring GTM for event tracking.

1.1: What Are Conversion Actions in Google Ads?
Conversion actions are the key steps you want users to take after interacting with your ads. Think of them as digital checkpoints that show when someone moves closer to becoming a customer or engaging with your brand. These actions could be anything from making a purchase, submitting a form, signing up for a newsletter, making a phone call, downloading an app, or any custom event tied to your business goals.
When a user completes one of these actions after clicking on your ad, Google Ads marks it as a conversion. This data is then used to fine-tune your campaigns automatically, helping you get better results over time.
But conversion actions aren’t just about counting clicks. They provide the data Google Ads needs to refine bidding strategies, focus your budget on the best-performing keywords and audiences, and highlight which campaigns deliver the highest return on investment. Without tracking these actions, you’re essentially flying blind - unable to tell which ads are driving real results and which are just generating traffic.
For eCommerce businesses, tracking purchases and add-to-cart actions often yields the most valuable insights. Lead generation companies might focus on form submissions and sign-ups, while service-based businesses could prioritize phone calls or consultation requests. Agencies like Senwired often zero in on these specific actions because they directly tie to measurable outcomes for their clients.
1.2: How to Create a Conversion Action
Start by defining your campaign goals and identifying the user actions you want to track. In your Google Ads account, go to "Goals" and then select "Summary" under "Conversions."
Click to create a new conversion action and choose "Website" as your source. From there, select a category like "Submit lead form", "Purchase", or "Sign up." This choice impacts how Google Ads optimizes your campaigns and reports performance, so make sure it aligns with your objectives.
Give your conversion action a clear name. Instead of generic labels like "Conversion 1", use descriptive names such as "Contact Form Submission" or "Homepage Newsletter Signup."
Set up the conversion value based on your business model. For lead generation, assign a fixed value that represents the average worth of a lead - say, $65.00. For eCommerce, use dynamic values that reflect the actual purchase amount.
Decide whether to count "Every" action or just "One" per user. Choose "Every" for actions like multiple purchases and "One" for actions like form submissions, where duplicates from the same user aren’t typically useful.
Enable enhanced conversion tracking. This feature uses first-party data, like email addresses, to improve match rates and attribution accuracy. It’s a smart move in today’s privacy-conscious digital landscape.
Once everything is set up, you’ll receive a Conversion ID and Label, which you’ll need to configure tracking in Google Tag Manager (GTM).
1.3: Get the Conversion Tracking Tag
After saving your conversion action, Google Ads generates two important pieces of information: the Conversion ID and Conversion Label. These identifiers ensure that your conversion data is correctly linked to your account and the specific action you’re tracking.
To find these, go to the "Use Google Tag Manager" tab within your conversion action settings. Here, you’ll see the Conversion ID (a unique number for your Google Ads account) and the Conversion Label (a text string tied to the specific action).
Copy both values and store them securely. You’ll need these for your GTM setup, and even a small typo can disrupt tracking. Many advertisers create a spreadsheet or document to map conversion action names to their corresponding IDs and labels, which is especially helpful when managing multiple actions.
Initially, the status of your conversion action will show as "Inactive" or "No recent conversions." Don’t worry - this is normal. Once GTM starts sending data to Google Ads, the status will change to "Active", typically within 24 hours of publishing your GTM container.
To avoid errors, double-check that the conversion action name in Google Ads matches the labels you’ve saved. This extra step ensures accurate tracking and prevents issues with data attribution.
Step 2: Set Up Google Tag Manager for Conversion Tracking
Once you’ve got your Conversion ID and Label from Google Ads, it’s time to configure Google Tag Manager (GTM) to ensure accurate conversion tracking. This setup allows GTM to send conversion data to Google Ads whenever a conversion occurs. The process involves creating tags, setting up triggers to determine when those tags fire, and using variables to capture dynamic details like purchase amounts or lead values. Getting this right is critical for a smooth flow of reliable data.
Even small missteps in configuration can lead to gaps in your data. According to Google’s 2023 research, properly implementing Enhanced Conversions can increase measurement accuracy by over 5% - a boost that’s especially useful for businesses focused on lead generation.
Here’s how GTM works with Google Ads: when someone completes a conversion action on your site, GTM detects the event and sends the necessary data to Google Ads using tags. These tags rely on the unique identifiers from your Conversion ID and Label, and they fire based on the triggers you define. This seamless communication depends entirely on how well you configure your setup.
The importance of accuracy can’t be overstated. A 2024 Adswerve survey revealed that more than 60% of US advertisers have adopted or are planning to adopt server-side GTM within the next year. Why? Improved data accuracy and better privacy compliance are major factors driving this shift.
Before you go live, testing your configuration is a must. GTM’s Preview mode lets you simulate conversions and verify that your tags fire correctly. Skipping this step can lead to weeks of missed or inaccurate data, which could hurt your campaign performance.
Pro Tips for a Solid Setup:
Use clear, descriptive names for tags, triggers, and variables. Avoid vague labels like “Tag 1” or “Trigger A.” Instead, opt for names that explain their purpose, such as “Purchase Conversion Tag” or “Form Submission Trigger.”
Capture dynamic values, like the actual purchase amount, to provide Google Ads with detailed data. This helps optimize campaigns by offering more precise ROI insights.
Consider server-side tracking for better data accuracy, fewer issues with ad blockers, and improved privacy compliance.
Watch out for common mistakes. These include using incorrect triggers that fire on every page instead of specific conversion events, entering the wrong Conversion IDs or Labels, and failing to test tags before publishing. Such errors can inflate your conversion numbers, cause missed conversions, or even lead to complete tracking failures.
Lastly, as your website evolves, don’t forget to update your GTM configuration regularly. Conducting routine audits helps you catch and fix any discrepancies before they impact your campaigns or budget decisions.

2.1: Create a New Tag in GTM
Head over to the Tags section in your GTM container, click "New", and select "Google Ads Conversion Tracking." This step is essential for sending conversion data from your website to Google Ads without any hiccups.
Next, use the Conversion ID and Label you got earlier. These need to be entered into the tag configuration accurately - double-checking here can save you a lot of troubleshooting later.
When it comes to the conversion value field, you’ve got two choices. You can either set a fixed value (like $65.00 for each lead submission) or use a variable to capture dynamic values directly from your website. For example, if you’re tracking eCommerce transactions, dynamic values are a must since every purchase will have a different amount. On the other hand, if you’re tracking leads, assigning a fixed value that reflects the average worth of a lead to your business might make more sense.
Make sure to name your tag clearly and descriptively - something like "GAds – Conversion – LeadFormSubmit" works great. This way, managing and troubleshooting your tags later will be much easier. Once your tag is ready, set up triggers to determine exactly when it should fire.
2.2: Set Up Triggers for Conversion Events
Triggers are what make your conversion tag fire, so setting them up correctly is crucial. The trigger you choose depends entirely on the action that counts as a conversion on your website. For instance, if a form submission is your conversion event, a custom event trigger is usually the way to go. This trigger would fire when an event like or shows up in your data layer.
Another option is using page view triggers for conversions that redirect users to a thank-you page. For example, if your contact form sends users to after submission, you can set up a trigger to fire on that specific URL. However, custom events are often more reliable since they don’t rely on redirects, which can sometimes fail.
A case study by Loves Data showed how a business successfully set up Google Ads conversion tracking for form submissions. They created a Google Ads Conversion Tracking tag in GTM, entered the Conversion ID and Label, and used a custom event trigger (e.g., "form_submit"). This setup allowed them to track leads and fine-tune their Google Ads campaigns.
For actions like downloads or newsletter sign-ups, button click triggers are the way to go. These triggers can fire when users click specific buttons or links, and you can identify the right elements using CSS selectors or click text.
To avoid inflated conversion counts, make sure your triggers fire only on the events you’ve defined as conversions. Test your triggers thoroughly using GTM's built-in debugging tools to ensure they behave as expected. Once your triggers are good to go, you can use variables to pass dynamic data into your conversion tags.
2.3: Use Variables for Dynamic Tracking
Variables in GTM make your conversion tracking smarter by pulling dynamic data from your website and sending it to Google Ads. Some common variables include conversion value, transaction ID, and currency code. These variables can pull data from your data layer, form fields, or even page content, and they automatically insert this data into your conversion tags.
For example, a conversion value variable ensures that each transaction's unique amount is captured and sent to Google Ads. Instead of reporting every purchase as the same fixed value, Google Ads will receive the exact purchase amount in U.S. dollars.
Analyticsmania shared an example where a developer pushed a "subscribed" event to the dataLayer when a user submitted a newsletter form. A trigger in GTM fired the Google Ads Conversion Tracking tag on this event, making it possible to track newsletter sign-ups as conversions in Google Ads.
Transaction ID variables are incredibly useful for avoiding duplicate conversion counts. If a user refreshes or revisits the confirmation page, the same transaction ID ensures Google Ads doesn’t mistake it for multiple conversions.
Currency variables are especially handy for businesses operating internationally or dealing in multiple currencies. While most U.S. businesses stick to USD, international eCommerce sites might need to capture the actual currency used in each transaction for accurate reporting.
To set this up, head to the Variables section in GTM and create user-defined variables like Data Layer Variables, JavaScript Variables, or DOM Elements. Once created, reference these variables in your conversion tags to make your tracking as precise as possible.
Step 3: Test and Validate Conversion Events
With your GTM conversion tags set up, the next step is to test and confirm they’re working as expected. This ensures you’re not missing any conversions or accidentally recording duplicates.
Google Tag Manager simplifies testing with its built-in Preview mode. This tool lets you simulate user actions in a controlled environment, so you can see exactly which tags are firing without affecting your live data. Once in Preview mode, confirm that all tags are triggering as intended.
3.1: Use GTM's Preview Mode
Start by using GTM's Preview mode to test your conversion events. Click the Preview button in GTM, which connects to your website via Tag Assistant. Enter your site’s URL in the preview connection, and you’re ready to begin.
For accurate testing, use an incognito browser window. This prevents cached data or browser extensions from interfering with your results. Ensure all necessary triggers and variables are loaded before you proceed.
Next, replicate the user behavior that should activate your conversion. For example, if you’re tracking form submissions, fill out and submit the form as a user would. For eCommerce conversions, complete an actual purchase. Avoid relying on simulated data - real actions provide the most reliable results.
In the Preview panel, check the left-hand navigation to confirm your event appears and that your Google Ads conversion tag triggers correctly. You should see your custom event (e.g., "generate_lead" or "purchase") listed. When you click on it, the tag summary should indicate your conversion tag as "Fired."
For an extra layer of validation, use the Tag Assistant Chrome extension. This tool shows which Google Tags are loaded on your site and verifies that conversions are being captured. Click on the relevant Google Tag in Tag Assistant, then select "Conversions" to confirm the action was recorded during your test.
3.2: Fix Common Errors
Even with a careful setup, some issues might pop up during testing. One of the most frequent problems is tags not firing due to incorrect triggers. If your conversion tag isn’t firing, double-check that your trigger configuration matches the event name exactly. Remember, event names are case-sensitive - "Purchase" and "purchase" are treated as entirely different events.
Another common error is the "Conversion linker tag missing in container" warning. This can disrupt tracking, especially for cross-domain scenarios. To fix it, create a Conversion Linker Tag with the default "All Page Views" trigger before testing your tags.
If tags fire but don’t send data to the right place, the issue could be missing or incorrect Conversion ID and Label values. Go back to your Google Ads account and confirm these values match what you’ve entered in GTM.
Use GTM Preview mode and the Tag Assistant extension to verify that the correct tags fire when user actions trigger the corresponding event in the data layer. If the event is missing or contains incorrect data, you’ll need to adjust your website’s code or GTM variables.
Browser ad blockers can also prevent tags from firing. Test in an incognito window with ad blockers turned off to rule this out. Keep in mind that some users may have strict privacy settings that block tracking, but your testing environment should be clean.
For eCommerce tracking, watch out for currency and value formatting issues. Make sure dollar amounts are displayed correctly for U.S. businesses, using the format $1,234.56. Also, confirm that dynamic values are pulling the right data from your eCommerce platform.
Once you’ve addressed any issues, move on to validating your data flow in Google Ads.
3.3: Check Conversions in Google Ads
After confirming that your tags are firing correctly in GTM, publish your container and test the conversion action again. Use clear naming conventions when publishing - include a brief description of the updates for easy reference later.
Once published, give it at least 24 hours for the data to appear in Google Ads. This delay is normal, so don’t worry if conversions don’t show up right away.
After waiting, go to Tools & Settings > Measurement > Conversions in Google Ads to check the status of your conversion action. Initially, it may show as "Inactive", but once Google starts receiving data, it should update to "Recording conversions."
The conversion count should reflect the test actions you performed. For example, if you submitted two test forms, you should see a count of 2 (or higher if real users also converted). Keep in mind, reporting delays might slightly affect the timing, but the numbers should align.
If tags fired correctly but conversions aren’t showing in Google Ads, check for mismatched event parameters or cookie blocking issues. The Conversion Linker tag is essential for managing cross-domain tracking and cookies, so ensure it’s properly implemented.
Finally, confirm that conversions are attributed to the correct campaigns and ad groups. This data helps pinpoint which parts of your Google Ads account are driving the most valuable actions.
Step 4: Advanced Setup: Enhanced Conversions and Server-Side Tracking
Once you’ve nailed the basics, it’s time to dive into advanced tracking techniques. These features help tackle issues caused by privacy restrictions and ad blockers, ensuring you maintain accurate data and improve campaign performance.
Enhanced Conversions and server-side tracking are designed to bridge gaps in data collection. Enhanced Conversions rely on first-party data from your website, like email addresses or phone numbers, to improve match rates between conversions and Google Ads clicks. This hashed customer information helps Google Ads link conversions to the correct ad interactions, even when cookies are blocked or unavailable.
4.1: Turn On Enhanced Conversions
To activate Enhanced Conversions in Google Ads, head to Tools & Settings > Measurement > Conversions, select your conversion action, and toggle on Enhanced Conversions. Under Edit settings, scroll to the Enhanced Conversions section and choose Google Tag Manager (GTM) as your implementation method.
Next, in GTM, update your existing Google Ads Conversion Tracking tag to include first-party data from your site. You’ll need to create a User-Provided Data variable in GTM, which pulls customer details from your site’s data layer or form fields - like email addresses, phone numbers, or names entered during checkout or form submissions. Configure this variable to match your website’s structure (e.g., or ). GTM will automatically hash this data before sending it to Google Ads.
Once set up, test everything using GTM’s Preview Mode. Perform a test conversion to ensure the User-Provided Data variable is correctly populated and the conversion tag fires with both standard and enhanced data. This setup improves match rates and attribution accuracy by giving Google Ads more information to connect conversions with ad interactions.
4.2: Set Up Server-Side Tracking
Server-side tracking takes things a step further, processing conversion data on your server to bypass browser privacy restrictions and ad blockers.
To get started, create a server container in Google Tag Manager. In the GTM interface, select New Container, choose Server as the container type, and follow the setup instructions. You’ll receive a server container ID and configuration details to deploy it on your hosting platform - Google Cloud Platform is a popular choice.
Once your server container is ready, focus on integrating it with your web container. Add a Google Ads Conversion Tracking tag and a Conversion Linker tag to the server container for accurate cross-domain attribution. Update your web container so it sends conversion data to the server container, ensuring the same triggers fire as before.
The server container processes this data and forwards the relevant conversion details to Google Ads. This method ensures a more reliable and privacy-compliant data flow, reducing the impact of browser-based interference. While server-side tracking requires a more technical setup, it significantly boosts data reliability.
Use GTM’s server-side Preview Mode alongside Google Ads conversion reports to monitor your setup. When everything is configured correctly, data should flow seamlessly from user actions through your server container to Google Ads, providing consistent and accurate conversion insights. This advanced approach strengthens your tracking system without disrupting your existing setup.
Step 4: Advanced Setup: Enhanced Conversions and Server-Side Tracking
With privacy restrictions and ad blockers becoming more common, tracking conversions accurately has become a challenge. Enhanced Conversions and server-side tracking offer solutions by leveraging first-party data and server processing instead of relying solely on browser cookies.
Building on your Google Tag Manager (GTM) setup, these advanced tracking methods help secure your conversion data. Enhanced Conversions collect customer details - like email addresses or phone numbers - from website forms, then hash the data before sending it to Google Ads. This ensures Google can match conversions to the right ad clicks, even when traditional tracking methods fall short. Meanwhile, server-side tracking processes conversion data on your server, bypassing browser limitations and ad blockers. Together, these approaches ensure your data remains accurate in a privacy-focused landscape.
4.1: Turn On Enhanced Conversions
To enable Enhanced Conversions, log in to Google Ads and navigate to Goals > Conversions > Settings. Toggle the feature on and select Google Tag Manager as your implementation method.
Next, open GTM and create a customer data variable to capture information from your website. Go to Variables > New and choose User-Provided Data with Manual Configuration. This variable pulls data from your site's forms or data layer - typically including email addresses, phone numbers, and other customer details.
Match the variable to your website's structure. For instance, if customer emails are stored in your data layer as , configure the variable to reference . If you're capturing data directly from forms, use something like to pull the email field from checkout or contact forms.
Once your variable is set up, add it to your existing Google Ads Conversion Tracking tag. Locate the User-Provided Data section in the tag configuration and select the variable you just created. GTM will automatically hash the data to comply with privacy laws like the California Consumer Privacy Act (CCPA).
After setting this up, test a conversion to ensure your variable is capturing the correct information and triggering the Enhanced Conversions tag. Once confirmed, you can move on to server-side tracking for even more reliable data handling.
4.2: Set Up Server-Side Tracking
Server-side tracking improves data reliability by processing conversion events on your server. Start by creating a Server container in GTM to get the required ID and configuration details. Many users host this container on Google Cloud Platform, but other cloud providers that support GTM server containers work as well.
Configure the server container with the necessary tags for Google Ads tracking. Add a Conversion Linker tag to handle cross-domain attribution. Then, create a Google Ads Conversion Tracking tag by entering your Conversion ID and Conversion Label. Set up triggers for specific conversion events, such as purchases or form submissions.
Here’s how the process works: your web container captures conversion events and sends them to the server container. The server processes this data and forwards it to Google Ads. This bypasses browser-based restrictions, ensuring consistent tracking even when ad blockers are in use.
To integrate your web container with the server container, update your existing GA4 tags to send conversion events to your server endpoint. The server container receives these events, applies the Conversion Linker for accurate attribution, and fires the Google Ads Conversion Tracking tag with the necessary data.
For Enhanced Conversions, ensure your User-Provided Data variable passes hashed customer information through the server container. The server processes this data and includes it in the conversion details sent to Google Ads, further improving accuracy and privacy compliance.
Use GTM’s Preview Mode to test your setup. Monitor the data flow from user actions all the way to your Google Ads conversion reports. When everything is configured correctly, this advanced setup will provide more accurate tracking and reduce data loss compared to browser-based methods.
Enhanced Conversions and Server-Side Tracking
Enhanced conversions and server-side tracking improve the accuracy of your data by securely processing customer information and bypassing browser restrictions. These methods build on your existing Google Tag Manager (GTM) setup to ensure privacy-compliant and reliable tracking.
Enhanced conversions use SHA256 hashing to securely transmit customer details - like email addresses and phone numbers - to Google Ads for better attribution. This allows you to connect conversions to ad interactions while keeping user data protected.
Server-side tracking processes conversion data on your server instead of relying on the user's browser. This approach helps bypass browser restrictions and ad blockers, ensuring more accurate tracking.
4.1: Turn On Enhanced Conversions
To enable enhanced conversions, you’ll need to configure both Google Ads and Google Tag Manager (GTM). Start by logging into your Google Ads account, then navigate to Goals > Conversions. Choose the conversion action you want to enhance, click Edit settings, and enable the Enhanced Conversions option. Select Google Tag Manager as your implementation method, which allows GTM to handle the hashed data.
Next, head to GTM to create a variable that captures user-provided data. Go to Variables > New, and set up a variable (commonly called "User-Provided Data") to pull customer information from your website’s forms or data layer. Ensure this variable is configured to capture relevant data like email addresses or phone numbers.
Once your variable is ready, add it to your existing Google Ads Conversion Tracking tag. In the tag’s configuration, locate the User-Provided Data section and link your newly created variable. GTM will automatically hash the data using SHA256 before sending it to Google Ads.
Before finalizing, use GTM’s Preview Mode to test your setup. Confirm that the hashed data is being captured correctly and that the conversion tag is firing as expected.
For a more robust setup, consider integrating your server container to consolidate conversion tracking data.
4.2: Set Up Server-Side Tracking
Server-side tracking takes your tracking to the next level by processing conversion data on your server. This method has gained popularity, particularly in eCommerce, where adoption increased by over 50% in 2024 due to growing privacy concerns and stricter browser policies.
To begin, create a Server container in GTM. This container processes data on your server, sidestepping client-side limitations like ad blockers. While many businesses use Google Cloud Platform to host their server containers, other cloud providers can work just as well.
Ensure your server container is set up to handle cross-domain attribution. Then, create a Google Ads Conversion Tracking tag using the Conversion ID and Conversion Label provided by Google Ads. Configure triggers for the events you want to track - such as purchases or form submissions. Your server container will receive these events from your web container, process the data, and forward it to Google Ads, even if client-side tracking is blocked.
To connect your web container with your server container, update your existing conversion tags to send data to your server endpoint. The server will process the information, apply Conversion Linker logic, and then forward the data to Google Ads.
In January 2024, an eCommerce retailer that implemented server-side GTM alongside enhanced conversions reported a 28% increase in tracked conversions and a 15% improvement in Google Ads ROAS. This shift, led by their digital marketing manager with support from Stape.io, highlights the potential of server-side tracking.
For maximum accuracy, pass your User-Provided Data variable through the server container. The server will hash the customer data before including it in the conversion data sent to Google Ads.
Server-side tracking can increase conversion attribution rates by up to 30% compared to client-side tracking, especially for users with ad blockers or strict privacy settings. However, this setup requires technical expertise and careful optimization to avoid latency issues. Always test your configuration using GTM’s Preview Mode, monitoring the data flow from user actions to your Google Ads reports. When done right, this advanced setup delivers precise tracking while adhering to privacy standards.
