How to Set Up Google Tag Manager
Set Up an Account
Setting up a free account is an easy two-step process, but it’s separate from any of your other Google Analytics or Gmail accounts. To ensure a painless setup for you, we’ve recorded our process for setting up an account.
Here’s what you do:
1. Sign up for an account.
Go to the Google Tag Manager and click the green “Sign Up for Free” button. It will ask you to input your account name (company), country, and website URL, as well as where you want to use Google Tag (web, iOS, android, AMP). When you’re finished, click the blue “Create” button.
2. Follow the coding instructions.
Next, you’ll be given codes and instructions to include one code high in the <head> of your page, and the other after the opening <body> tag. You can do this now, or apply the codes to your site later (they are accessible in your dashboard). Once you’re done, click “Ok”.
Set Up a Tag
Once you have a Google Tag Manager account, the first thing you’re going to want to learn is how to set up a tag.
You can create unlimited configurations of tags in Google Tag Manager.
This is helpful for creating in-depth reports on your audience’s behavior, but it can become inefficient if you don’t organize your tags properly.
Google recommends using the following naming convention: tag type - name of app - detail.
Perhaps you name one tagging configuration, “AdWords conversions - iOS - 2018-02 campaign” and then another, “Google Analytics - CTA - About Us page”.
This way, you can correctly identify and collect data related to specific campaigns or pages.
For instance, the second tag, “Google Analytics - CTA - About Us page,” tells you how well your About Us call-to-action button is performing. That information is valuable, and might be lost if you named your tags more generally, like, “CTA button”.
Now that we’ve cleared that up, let’s check out how to set up a tag:
1. Create a new tag in the Google Tag Manager dashboard.
Within your Google Tag Manager dashboard, click the “Add a New Tag” button, circled below in red.
2. Configure your tag.
Title your tag, and then click anywhere in the top “Tag Configuration” box, to choose a tag type.
3. Select a tag type.
There are dozens of tag types (they are not all displayed here, and you can also customize a tag type). Example: “Classic Google Analytics”.
4. Link your tag to Google Analytics tracking.
If you want your tag tracked in Google Analytics, the next step will be to input your Web Property ID, found in your Google Analytics account. Then, select a “Track Type”. In this example, we selected “Page View”, but there are plenty of other options.
5. Select a trigger to determine when the tag is recorded.
Next, decide a trigger (a trigger means when you want the tag recorded, i.e. “every time someone visits the page”). In this example, we select “All Pages”, to get insights every time someone views any of my web pages, but this varies depending on your purposes.
6. Save your tag.
When you’re happy with the information in the “Tag Configuration” and “Triggering” boxes, click the blue “Save” button.
7. Activate your tag by pressing "Submit."
Next, click the blue “Submit” button. Your tag won’t work until you do so.
When you click “Submit”, you’ll be taken to this “Submission Configuration” page. There are two options: “Publish and Create Version” or “Create Version”. Since I’m ready to push the tag onto all my site pages, I selected “Publish and Create Version”, and then I pressed the blue “Publish” button in the top right.
8. Add a name and description to your tags to keep them organized.
Finally, you’ll be shown this “Container Version Description”. To keep your tags organized, add a name and description to understand what you’re trying to record with this tag.
9. Ensure your tag appears in your “Version Summary” report.
Now, you’ve successfully created your first tag.
