Google Tag Manager

1) Create a Tag: To create a new tag, click the Tags option in the left-hand sidebar of GTM and then click the New button.

2) Configure: In the Untitled Tag box that appears (shown in next slide, you can click in the Tag Configuration box or click the pencil icon in the upper-right corner.

3) Select Custom HTML: On the next screen, you see all of the available tag types, including Google-related tags, custom tags, and a More section that's full of third-party tags. Use the Custom HTML option.

4) Paste the Pixel: Copy and paste the pixel script into the Custom HTML box. This is a good time to give the pixel a name like "Landing Page Pixel," so you remember what this pixel does.

5) Add a Trigger: Every pixel must have at least one trigger to fire. The trigger tells the pixel to fire when the specified event is detected. To add a trigger to your pixel, click in the Triggering box below "Tag Configuration." On the Choose a Trigger screen that appears, click the plus sign in the upper right to add a new trigger. When the untitled trigger screen appears, click in the Trigger Configuration box to select the type of trigger you want to add. For example, if you want to track Lead Form Submissions for a financial advertiser's loan application page, select "Form Submission."

* When you're done, name and save any triggers you've added. Save your pixel and Google Tag Manager takes you back to the main Workspace tab.


6) Test: To make sure the pixel is working, click the Preview button in the upper right. After you click Start Preview, an orange bar appears to let you know you're in preview mode. Now open a new browser tab, go to your website, and refresh the page. If all is working as it should, a giant window pops up at the bottom, showing how you've set up the pixels behind the scenes in Google Tag Manager. Then, simply look for the pixel you created in the Tags Fired on This Page area.

7) Publish: After you know everything is working, you can publish the pixel and create a version. To do that, click the Submit button in the upper right, and the Submit Changes screen appears.
a)Make sure Publish and Create Version is the selected configuration and add a brief description of what you did in the Version Name box. This description helps anyone else working in the container.
b)When you're done, click Publish, and Google Tag Manager takes you to the Versions tab, where you can see the backups it keeps. Click the Workspace tab, and you'll see workspace changes go back to zero, which means everything is up to date.
