Google Tag Manager

Dub's Google Tag Manager integration allows you to track conversion events directly from Google Tag Manager.

Prerequisites#

First, you'll need to enable conversion tracking for your Dub links to be able to start tracking conversions:

Option 1: On a workspace-level

To enable conversion tracking for all future links in a workspace, you can do the following: To enable conversion tracking for all future links in a workspace, you can do the following:

1. Navigate to your workspace's Tracking settings page.
2. Toggle the Workspace-level Conversion Tracking switch to enable conversion tracking for the workspace.

This option will enable conversion tracking in the Dub Link Builder for all future links.

Option 2: On a link-level

If you don't want to enable conversion tracking for all your links in a workspace, you can also opt to enable it on a link-level.

To enable conversion tracking for a specific link, open the Dub Link Builder for a link and toggle the Conversion Tracking switch.

Tip

You can also use the C keyboard shortcut when inside the link builder to quickly enable conversion tracking for a given link.

Option 3: Via the API

Alternatively, you can also enable conversion tracking programmatically via the Dub API. All you need to do is pass trackConversion: true when creating or updating a link:

Node.jsPythonGoRuby

const link = await dub.links.create({  url: "https://dub.co",  trackConversion: true,});

Install Dub via Google Tag Manager#

There are 2 steps to install the Dub Analytics script via Google Tag Manager:

1. Add Dub Analytics script to GTM
2. Create User-Defined Variable for dub_id Cookie

Step 1: Add Dub Analytics script to GTM#

First, you'll need to add the Dub Analytics script to your website using Google Tag Manager.

In your GTM workspace, navigate to the Tags section and click New to create a new tag.

Select Custom HTML as the tag type and add the following code:

<script>  (function (c, n) {    c[n] =      c[n] ||      function () {        (c[n].q = c[n].q || []).push(arguments);      };    var methods = ["trackClick", "trackLead", "trackSale"];    for (var i = 0; i < methods.length; i++) {      (function (method) {        c[n][method] = function () {          var args = Array.prototype.slice.call(arguments);          args.unshift(method);          c[n].apply(null, args);        };      })(methods[i]);    }    var s = document.createElement("script");    s.defer = 1;    s.src = "https://www.dubcdn.com/analytics/script.conversion-tracking.js";    s.setAttribute("data-publishable-key", "dub_pk_xxxxxxxx"); // Replace with your publishable key    document.head.appendChild(s);  })(window, "dubAnalytics");</script>

Configure the tag to fire on All Pages by setting the trigger to All Pages - Page View.

Name this tag "Dub Analytics script" and save it.

Step 2: Create User-Defined Variable for dub_id Cookie#

To read the dub_id cookie that Dub Analytics script sets, you'll need to create a User-Defined Variable in Google Tag Manager.

In your GTM workspace, navigate to the Variables section and click New to create a new variable.

Configure the variable with the following settings:

• Variable Type: Select 1st Party Cookie
• Cookie Name: Enter dub_id
• Variable Name: Name it "Dub ID Cookie"

Click Save to create the variable.

Tracking lead events#

There are two ways to track lead events with Google Tag Manager:

• Thank You Page Tracking (Recommended)
• Form Submission Tracking

Option 1: Thank You Page Tracking (Recommended)#

This method tracks leads when users land on a thank-you or success page after completing a form. This approach is more reliable as it's less likely to be blocked by ad blockers and provides better data accuracy.

Create a Custom HTML tag with the following code:

<script>  (function () {    // Get query parameters from URL    var params = new URLSearchParams(window.location.search);    var email = params.get("email");    var name = params.get("name");    // Get dub_id from cookie using GTM variable    var clickId = {{Dub ID Cookie}} || "";    // Only track the lead event if email and clickId are present    if (email && clickId) {      dubAnalytics.trackLead({        eventName: "Sign Up",        customerExternalId: email,        customerName: name || email,        customerEmail: email,        clickId: clickId,      });    }  })();</script>

Configure this tag to fire on specific pages by creating a Page View trigger with conditions:

• Trigger Type: Page View
• This trigger fires on: Some Page Views
• Add conditions like:
  • Page URL contains /thank-you
  • Or Page Path equals /success
  • Or whatever URL pattern matches your thank-you pages

Name this tag "Dub Lead Tracking - Thank You Page" and save it.

Option 2: Form Submission Tracking#

This method tracks leads immediately when users submit forms on your website. Note that this approach may be less reliable due to ad blockers and timing issues.

Create a Custom HTML tag with the following code:

<script>  (function () {    // Get form data - customize these selectors based on your form    var name = document.getElementById("name")      ? document.getElementById("name").value      : "";    var email = document.getElementById("email")      ? document.getElementById("email").value      : "";    // Get dub_id from cookie using GTM variable    var clickId = {{Dub ID Cookie}} || "";    // Only track the lead event if email and clickId are present    if (email && clickId) {      dubAnalytics.trackLead({        eventName: "Sign Up",        customerExternalId: email,        customerName: name || email,        customerEmail: email,        clickId: clickId,      });    }  })();</script>

Configure this tag to fire on Form Submission by creating a new trigger:

• Trigger Type: Form Submission
• This trigger fires on: Some Forms (or All Forms if you want to track all form submissions)
• Add conditions to specify which forms should trigger lead tracking

Name this tag "Dub Lead Tracking - Form Submission" and save it.

Tracking sales events#

There are two ways to track sales events with Google Tag Manager:

• Order Confirmation Page Tracking (Recommended)
• Checkout Form Submission Tracking

Option 1: Order Confirmation Page Tracking (Recommended)#

This method tracks sales when users land on an order confirmation or success page after completing a purchase. This approach is more reliable as it's less likely to be blocked by ad blockers and provides better data accuracy.

Create a Custom HTML tag with the following code:

<script>  (function () {    // Get query parameters from URL    var params = new URLSearchParams(window.location.search);    var customerId = params.get("customer_id");    var amount = params.get("amount");    var invoiceId = params.get("invoice_id");    // Only track if customer ID and amount are present    if (customerId && amount) {      // Track the sale event      dubAnalytics.trackSale({        eventName: "Purchase",        customerExternalId: customerId,        amount: parseInt(amount), // Amount in cents        invoiceId: invoiceId || undefined,        currency: "usd", // Customize as needed        paymentProcessor: "stripe", // Customize as needed      });    }  })();</script>

Configure this tag to fire on specific pages by creating a Page View trigger with conditions:

• Trigger Type: Page View
• This trigger fires on: Some Page Views
• Add conditions like:
  • Page URL contains /order-confirmation
  • Or Page Path equals /checkout/success
  • Or whatever URL pattern matches your order confirmation pages

Name this tag "Dub Sales Tracking - Order Confirmation" and save it.

Option 2: Checkout Form Submission Tracking#

This method tracks sales immediately when users complete checkout forms on your website. Note that this approach may be less reliable due to ad blockers and timing issues.

Create a Custom HTML tag with the following code:

<script>  (function () {    // Get checkout data - customize these selectors based on your form    var customerId = document.getElementById("customer_id")      ? document.getElementById("customer_id").value      : "";    var amount = document.getElementById("amount")      ? document.getElementById("amount").value      : "";    var invoiceId = document.getElementById("invoice_id")      ? document.getElementById("invoice_id").value      : "";    // Only track if customer ID and amount are present    if (customerId && amount) {      // Track the sale event      dubAnalytics.trackSale({        eventName: "Purchase",        customerExternalId: customerId,        amount: parseInt(amount), // Amount in cents        invoiceId: invoiceId || undefined,        currency: "usd", // Customize as needed        paymentProcessor: "stripe", // Customize as needed      });    }  })();</script>

Configure this tag to fire on Form Submission by creating a new trigger:

• Trigger Type: Form Submission
• This trigger fires on: Some Forms (or All Forms if you want to track all form submissions)
• Add conditions to specify which forms should trigger sales tracking (e.g., checkout forms)

Name this tag "Dub Sales Tracking - Checkout Form" and save it.

Here are the properties you can include when sending a sale event:

Testing your setup#

To test your GTM setup, you can use the Preview mode in Google Tag Manager:

1. Enable Preview Mode: In your GTM workspace, click the Preview button in the top right corner
2. Enter your website URL and click Connect
3. Test your chosen tracking method:
   • For Option 1 (Order Confirmation): Navigate to your order confirmation page with query parameters (e.g., ?customer_id=123&amount=1000&invoice_id=inv_456)
   • For Option 2 (Form Submission): Navigate to a checkout page and complete a test purchase form
4. Check the GTM debugger to see if your tags are firing correctly

Verify conversion tracking#

You can also verify that conversion events are being tracked by:

1. Checking your browser's developer console for any JavaScript errors
2. Using the Network tab to see if requests are being sent to Dub's analytics endpoint
3. Viewing your Dub dashboard to confirm that sale events are appearing in your analytics

Common troubleshooting tips#

• Tag not firing: Check that your triggers are configured correctly and that the conditions match your page structure
• Form data not captured (Option 2): Verify that your DOM selectors match your actual checkout form field IDs or names
• Query parameters missing (Option 1): Ensure your checkout process redirects to the confirmation page with the required query parameters
• Amount formatting: Ensure amounts are in cents (e.g., $10.00 = 1000 cents)
• Multiple events: Make sure your tags aren't firing multiple times by checking trigger conditions
• Duplicate tracking: Verify you've only implemented one tracking method (Option 1 OR Option 2, not both)
• Missing publishable key: Ensure you've replaced the placeholder with your actual publishable key
