You can easily add ClickGuard's conversion tracking with Google Tag Manager. Please note that this tutorial assumes you've created one or more custom events in Google Tag Manager that would normally trigger conversion tracking.

Log in to your GTM account and select the correct website project, and follow these steps:

Step 1 - Add a new tag

Click on the "New Tag" button:

In "Tag Configuration" select the “Custom HTML Tag” product:

Step 2 - Paste the conversion code

Visit Account Settings to obtain the conversion code. 
Go to Settings → Tracking code → Conversion tracking



 

In the "Tag Configuration" card, paste the code into the "Custom HTML" text box:

 

If you want to track a conversion on other events, like clicking on a button (Phone Call click, Purchase button, Form submission, etc.) you need to execute the following code when those events happen.

<script>
CG.conversion()
<script>

With a message:

<script>
CG.conversion('Sample conversion message')
</script>

Step 3 - Set triggers

Within the Triggering card - choose your event that is supposed to trigger conversion tracking (in this example, the signUp event):

Step 4 - Save changes

Save your new tag and submit changes. You've just installed the conversion code on your website.

Note: It's important to ensure that the Tracking Code is loaded on the site before the conversion script.
