If you're running Google Ads and not tracking conversions properly, you're flying blind.

You might be getting clicks, spending money, and even making sales, but without the conversion ID, Google Ads has no clue what's working. And neither do you.

Whether setting up tags in Google Tag Manager, embedding scripts on Shopify, or troubleshooting why your ads aren't reporting sales, knowing how to find the Conversion ID in Google Ads is essential.

But here's the catch: Google doesn't make it obvious. You're not alone if you've ever poked around the interface wondering, "Where is the conversion ID in Google Ads?".

In this guide, you'll get a clear, step-by-step walkthrough to:

• Find your conversion ID and label, the two magic keys to accurate tracking
• Understand what they mean (and why they matter)
• Implement them across platforms like GTM, Shopify, and custom-built sites
• Troubleshoot common mistakes that kill your conversion data

By the end, you won't just know where to find your conversion ID, you'll learn how to use it confidently, correctly, and in ways that drive better results from your ad budget.

Let's dive in and get you tracking like a pro.

What Is a Conversion ID in Google Ads?

If you've ever tried to connect your website or app to Google Ads for conversion tracking, you've probably seen two important terms pop up:

• Conversion ID
• Conversion Label

These aren't just random strings of code, they're the digital glue that ties your ad clicks to real-world actions like purchases, form submissions, bookings, or sign-ups. Without them, Google Ads cannot know whether your campaigns are working or wasting money.

Let's break it down.

What Is a Conversion ID?

A Conversion ID is a unique identifier assigned to your Google Ads account's tracking setup. Think of it as your account's fingerprint for conversion tracking.

Example:

AW-123456789 → The part after "AW-" is your Conversion ID.

This ID stays the same across all the conversions you create within one Google Ads account. It tells Google: "Hey, this action came from my ad campaigns."

What Is a Conversion Label?

A Conversion Label is a unique code tied to a specific conversion action, like a purchase, a lead form submission, or a phone call. Each label is paired with your conversion ID and tells Google what action was taken.

Example:

AW-123456789/abcDEFghijkLMnoP → The second part (after the slash) is the Conversion Label.

You can create multiple conversion labels under the same ID to track different events. Think of the label as the "name tag" for each conversion.

Conversion ID vs. Conversion Label: What's the Difference?

Here's a quick table to help you see how they differ:

Why Does This Matter?

If you're using any of the following, you need the correct Conversion ID and Label combo:

• Google Tag Manager tags for Google Ads
• Manual installation of Google's tracking script (gtag.js)
• CRM tools or platforms like Shopify, WordPress, Webflow, Wix, or Zapier
• Server-side API conversion tracking
• Enhanced conversions for leads or offline tracking

Mess up your conversion ID or label, and Google Ads won't track conversions. That means:

• No optimization for conversions
• Inaccurate reporting
• Wasted ad budget

And here's the kicker: Google uses this data to train Smart Bidding strategies, like Maximize Conversions or Target ROAS. Your campaigns won't learn or improve if conversions aren't tracked correctly.

Method 1: How to Find Conversion ID in Google Ads UI

If you're setting up Google Ads conversion tracking for the first time, or troubleshooting why it isn't working, the fastest way to find your Conversion ID and Label is directly from your Google Ads account.

This method is ideal if:

• You've created at least one conversion action (e.g., Purchase, Lead, Signup)
• You plan to use the conversion in Google Tag Manager, gtag.js, or third-party tools

Here's a simple, step-by-step guide to locate it:

Step-by-Step: Find Your Conversion ID in Google Ads

Step 1: Log in to Your Google Ads Account

Go to ads.google.com and sign in with the account that manages your campaigns.

Step 2: Open the "Tools & Settings" Menu

In the top right corner, click the wrench icon.

Under the "Measurement" column, select Conversions.

Step 3: Locate Your Conversion Action

You'll see a list of all existing conversion actions, such as "Purchase," "Lead," or "Contact Form."

Click on the name of the conversion action you want to track. If you haven't created one yet, click the blue + New conversion action button to set one up first.

Step 4: Click "Tag Setup"

Once inside your selected conversion, scroll to the Tag Setup section and click it.

You'll now be given multiple options to implement the tag.

Step 5: Choose "Install the Tag Yourself"

Select the option that says "Install the tag yourself" (or similar wording, Google occasionally updates its interface).

Here, you'll see the complete JavaScript snippet that includes:

• Conversion ID (e.g., AW-123456789)
• Conversion Label (e.g., AbCdEfGhIjKlMnOpQr)

These two values are exactly what you need.

Example Snippet

Google gives you the full tag as three pieces. First, a loader script tag pointing at googletagmanager.com/gtag/js with your Conversion ID in the URL. Second, a config block that initializes gtag with your Conversion ID:

window.dataLayer = window.dataLayer || [];
function gtag(){dataLayer.push(arguments);}
gtag('js', new Date());
gtag('config', 'AW-123456789');

And third, the actual conversion event, fired on the page where the conversion happens (your thank-you page, for example):

gtag('event', 'conversion', {
  'send_to': 'AW-123456789/AbCdEfGhIjKlMnOpQr',
  'value': 10.0,
  'currency': 'USD'
});

All three pieces need to sit inside script tags in your page's HTML, the loader and config block in the head, and the conversion event on whichever page the conversion actually happens.

In this example:

• AW-123456789 is your Conversion ID
• AbCdEfGhIjKlMnOpQr is your Conversion Label

What to Do With It

Once you've copied your conversion ID and label, you can:

• Paste them into a Google Tag Manager conversion tag
• Insert them in a Shopify script
• Embed them manually via gtag.js
• Use them in a Zapier Webhook or server-side API call

Method 2: Find Conversion ID in Google Tag Manager (GTM)

If you're managing tags through Google Tag Manager (GTM), and let's be honest, you probably are, then you don't need to dig through your Google Ads account every time. You can locate your Conversion ID and Label directly from your GTM workspace.

This is especially helpful if:

• Someone else set up the tags (e.g., a developer or agency)
• You're troubleshooting why conversions aren't firing
• You need to reuse the ID/label for another integration or platform

Here's how to quickly find it inside GTM:

Step-by-Step: How to Locate Google Ads Conversion ID in GTM

Step 1: Log in to Google Tag Manager

Head over to tagmanager.google.com and select the container for the website you're working on.

Step 2: Go to the "Tags" Section

On the left-hand panel, click Tags.

You'll see a list of all the tags installed on your website.

Step 3: Find Your Google Ads Conversion Tag

Look for a tag with a name like:

• "Google Ads Conversion: Purchase"
• "Google Ads: Lead Conversion"
• Or anything similar to what your conversion action tracks

Click on that tag to open its configuration.

Step 4: Identify the Conversion ID and Label

Once the tag opens:

• Under Tag Configuration, you should see "Google Ads Conversion Tracking" as the tag type
• Below that, you'll find two fields: Conversion ID (AW-XXXXXXXXX) and Conversion Label (a random-looking string)

These are the same values shown in your Google Ads account.

Note: The tag might be incomplete or set up incorrectly if you don't see a conversion label.

Bonus: How to Test the Tag in GTM

Previewing the tag and ensuring it fires correctly before publishing or reusing the ID/Label is smart.

Here's how:

• Click Preview in GTM
• Enter your site's URL
• Perform the conversion action (e.g., submit a form, make a test purchase)
• Check if your Google Ads Conversion tag fires in the debug window
• Use the Tag Assistant Chrome extension to double-check

Method 3: Find Conversion ID from Website Source Code

If you don't have access to the Google Ads UI or GTM account, but you know conversion tracking is already set up on your website, there's another way to find your Conversion ID and Label: by checking your site's source code.

This method is beneficial for:

• Marketers or developers auditing existing tracking
• Shopify or WordPress users using direct tag installs
• Verifying if the tag was installed correctly by a third party

Here's how you can locate it:

Step-by-Step: Find Google Ads Conversion ID in Page Source

Step 1: Visit the Web Page With the Conversion Action

This could be a thank-you page, checkout confirmation page, or any page where conversions are tracked.

Step 2: Right-Click and Select "View Page Source"

In Chrome or most browsers, right-click anywhere on the page and click View Page Source (or press Ctrl+U on Windows / Cmd+Option+U on Mac).

Step 3: Search for the Google Ads Snippet

Press Ctrl+F (or Cmd+F) and search for terms like:

• AW- (this will highlight your Conversion ID)
• gtag('event', 'conversion'
• send_to

You're looking for a snippet that looks like this:

gtag('event', 'conversion', {
  'send_to': 'AW-123456789/AbCdEfGhIjKlMnOpQr',
  'value': 50.0,
  'currency': 'USD'
});

From here:

• AW-123456789 is your Conversion ID
• AbCdEfGhIjKlMnOpQr is your Conversion Label

Optional: Use Chrome DevTools

You can also:

• Right-click → Inspect
• Go to the Sources or Network tab
• Reload the page and watch for calls to googleads.g.doubleclick.net

This can show real-time data if the tag fires correctly.

How Do You Use Your Conversion ID in the Tracking Setup?

Once you've found your Conversion ID and Conversion Label, the next step is putting them to work. Whether using Google Tag Manager, manual gtag.js installs, or integrating with platforms like Shopify, WordPress, or Zapier, your Conversion ID is the key to telling Google Ads when a valuable action happens.

Let's look at exactly how and where to use it.

1. Using Conversion ID with gtag.js (Manual Setup)

If you're not using Google Tag Manager, you can install Google Ads conversion tracking directly on your website using gtag.js.

Here's the basic structure. The loader script tag references your Conversion ID directly in its URL, and initializes gtag:

window.dataLayer = window.dataLayer || [];
function gtag(){dataLayer.push(arguments);}
gtag('js', new Date());
gtag('config', 'AW-123456789');

Then the conversion event itself, placed on the page where the conversion happens:

gtag('event', 'conversion', {
  'send_to': 'AW-123456789/AbCdEfGhIjKlMnOpQr',
  'value': 99.99,
  'currency': 'USD'
});

Both pieces need to be wrapped in script tags in your page's HTML, alongside the standard gtag.js loader script from Google that points at googletagmanager.com/gtag/js?id=AW-123456789. Replace AW-123456789 with your Conversion ID, and AbCdEfGhIjKlMnOpQr with your Conversion Label, throughout.

Use this on your thank-you page, purchase confirmation, or post-signup landing page.

2. Using Conversion ID in Google Tag Manager (GTM)

In GTM:

• Create a new tag: Google Ads Conversion Tracking
• Enter your Conversion ID and Conversion Label
• Add dynamic values like price or order total using GTM variables
• Set a trigger (e.g., "Form Submission" or "Page View: Thank You")
• Click Preview to test your tag before publishing it

3. Using Conversion ID in Shopify, WordPress, or Other Platforms

Most platforms with built-in Google Ads support (like Shopify) ask you for:

• Conversion ID
• Conversion Label
• Value (optional)
• Event type (purchase, sign-up, etc.)

Just paste your values in the appropriate integration fields.

4. Using It in Zapier or Webhooks

Running lead generation or eCommerce workflows? You can send conversion data from your CRM (e.g., HubSpot, Pipedrive) using:

• Google Ads Offline Conversion Import
• Webhooks with Google Ads API
• Required fields: gclid, conversion time, conversion ID/label

Common Mistakes to Avoid

Even seasoned marketers slip up with Google Ads conversion tags. Below are the blunders that derail tracking, and how to sidestep them.

How Do You Test If Your Conversion ID Works?

So, you've added your Conversion ID and label, but how do you know it's working?

Many campaigns lose money simply because tracking wasn't verified. Fortunately, testing your Google Ads conversion setup is quick and easy if you know where to look.

Here are the best ways to confirm your Conversion ID is firing properly:

1. Use Google Tag Assistant (Chrome Extension)

Google's official Tag Assistant tool checks if your tags are installed and firing correctly.

• Install the Tag Assistant (Legacy) Chrome extension
• Visit the page where the conversion should fire (e.g., thank-you page)
• Complete a test action (form fill, purchase, etc.)
• Click the Tag Assistant icon and look for "Google Ads Conversion Tracking" and a "Tag fired correctly" status

If you see a warning or no tag, revisit your GTM setup or embedded script.

2. Use GTM's Preview Mode

If you're using Google Tag Manager:

• Open your container in GTM
• Click Preview
• Enter your site's URL and perform the conversion action
• Check if your Google Ads Conversion Tag fires in the debug window

You'll see real-time confirmation under "Tags Fired" if it worked.

3. Check in Google Ads Diagnostics

In your Google Ads account:

• Go to Tools & Settings → Conversions
• Click into your conversion action
• Scroll to "Tag Diagnostics"
• Look for recent conversion activity or errors

Final Thoughts: Make Conversion Tracking Work for You

Finding your Google Ads Conversion ID isn't just a technical step, it's the foundation of innovative advertising. Without it, you're not tracking performance, you're guessing. And in digital marketing, guessing costs money.

Whether you're running lead generation, eCommerce campaigns, or service-based ads, accurate conversion tracking helps you:

• See what's working (and what's not)
• Feed Smart Bidding strategies the data they need
• Calculate real ROI and make data-driven decisions
• Avoid wasting budget on clicks that don't convert

The good news? You know precisely how to find your Conversion ID, from the Google Ads UI, GTM, or even directly in your site's source code. You've also seen how to implement it across platforms and test everything before launching.

But here's one last tip: always treat your conversion data as sacred.

Double-check your IDs, test your tags, and validate everything. When your tracking works, your ads perform better, and your budget goes further.

FAQs About Conversion ID in Google Ads

1. Where can I find my Conversion ID in Google Ads?

You can find it by going to Tools & Settings → Conversions → click on a conversion action → Tag Setup → Install the tag yourself. Your Conversion ID will appear in the tag snippet as AW-XXXXXXXXX.

2. What's the difference between a Conversion ID and a Conversion Label?

Conversion ID identifies your Google Ads account. Conversion Label identifies the specific action (like a lead form submission or purchase). You need both to track conversions correctly.

3. Can I use the same Conversion ID for multiple conversion actions?

Yes. The Conversion ID is account-specific and remains the same across all conversion actions. What changes for each action is the Conversion Label.

4. Can I track conversions without using the label?

No. Google Ads requires the Conversion ID and Label to register a specific action. Leaving out the label means Google won't know which conversion you're tracking.

5. Where do I place the Conversion ID and Label in gtag.js?

They go inside your conversion tag. Example: gtag('event', 'conversion', { 'send_to': 'AW-123456789/AbCdEfGhIjKlMnOpQr', 'value': 75.00, 'currency': 'USD' });

6. Can I use the Conversion ID with third-party platforms like Shopify or Zapier?

Absolutely. Many platforms allow you to input the Conversion ID and Label manually to track purchases, leads, or form submissions. Just make sure to test it after setting it up.

7. How can I check if the conversion tag is firing correctly?

Use the Google Tag Assistant Chrome extension, GTM Preview Mode, or the Google Ads Conversion Diagnostics section. These tools will tell you in real time whether your conversion tag has fired and whether it includes the right Conversion ID and Label.

8. Is Conversion ID the same as Pixel ID (like on Facebook)?

Not exactly. While both are unique identifiers used for tracking, Google Ads uses Conversion ID + Label, whereas Facebook uses Pixel ID. They serve similar purposes but are formatted and used differently.
