Google Analytics and Google Tag Manager Setup: A Simple 2026 Guide
Google Tag Manager setup sounds technical, but it is one of the most useful jobs you can do for your marketing. Without it, you can see visitors but not which ones called you or filled in a form. With it, you know exactly which pages, searches and ads bring in customers.
This guide walks through Google Analytics 4 and Google Tag Manager in plain language. If you would rather have it done for you, it is included in our SEO services in Saskatoon.
Quick answer: To complete a Google Tag Manager setup with GA4, first create a Google Analytics 4 property and copy its Measurement ID. Then create a Tag Manager account and web container, install its code on your website, and add a Google tag that uses your Measurement ID on all pages. Finally, track key events such as form submissions and phone clicks, test everything in Preview mode, and publish.
What Does a Google Tag Manager Setup Do?
The two tools work together, but they do different jobs, so a Google Tag Manager setup only makes sense once you know what each one is for.
Google Analytics 4 Versus Google Tag Manager
- First, Google Analytics 4 (GA4) is the free reporting tool that shows who visits your website and what they do
- Also, Google Tag Manager (GTM) is the free tool that adds tracking codes to your site without editing it each time
- Then GTM sends information, such as a form submission, to GA4 and your ad platforms
- Finally, GA4 turns that information into reports you can act on
In other words, Tag Manager collects the data and Analytics explains it.
1. Create Your GA4 Property
Before your Google Tag Manager setup, you need somewhere for the data to go.
GA4 Steps Before Your Google Tag Manager Setup
- First, sign in to Google Analytics and open Admin
- Then create an account and a property for your business
- Next, add a web data stream with your website address
- Finally, copy the Measurement ID, which starts with G-
Google explains each screen in its guide to setting up Analytics for a website. Keep the Measurement ID handy for the next step.
2. Start Your Google Tag Manager Setup With a Container
The container is the heart of your Google Tag Manager setup, because every tracking tag lives inside it.
How to Install Code During Google Tag Manager Setup
- First, sign in to Tag Manager and create an account for your business
- Then create a container and choose Web
- Next, copy the two code snippets Google gives you
- Finally, paste one in the head of every page and one just after the opening body tag
On WordPress, a trusted plugin can add the code for you. Google’s own Tag Manager installation guide shows where each snippet goes.
3. Connect GA4 to Your Google Tag Manager Setup
Next, your Google Tag Manager setup needs to send page views to GA4.
Adding the Google Tag to Your Google Tag Manager Setup
- First, go to Tags and create a new tag
- Then choose Google tag as the tag type
- Next, paste your GA4 Measurement ID
- Finally, set it to fire on all pages and save
As a result, every page view on your website now flows into GA4.
4. Track the Actions That Bring You Customers
Page views alone do not pay the bills. Therefore, the most valuable part of any Google Tag Manager setup is tracking the actions that lead to sales.
Key Events to Add to Your Google Tag Manager Setup
- First, contact form submissions
- Also, clicks on your phone number from a mobile device
- Then quote requests and booking clicks
- Finally, clicks on your email address or directions
In GA4, mark these as key events, which Google explains in its guide to key events. Once they are in place, you can see your real conversion rate and which sources bring the best leads.
5. Test, Then Publish
Never publish a Google Tag Manager setup without testing it first, because one wrong trigger can double-count or miss every lead.
How to Test Your Google Tag Manager Setup
- First, click Preview in Tag Manager and browse your site
- Also, submit a test form and tap your phone number
- Then confirm the right tags fire in the preview panel
- Finally, check GA4’s real-time report before you publish
Once everything fires correctly, click Submit to publish your container.
6. Respect Privacy and Consent
Tracking must follow the rules. So, make privacy part of your Google Tag Manager setup from day one.
Privacy Basics for Your Google Tag Manager Setup
- First, use a cookie banner that lets visitors accept or decline tracking
- Also, connect the banner to Google’s consent settings so tags respect each choice
- Then explain in your privacy policy what you track and why
- Finally, never send names, emails or phone numbers to Google Analytics
In short, good tracking and good privacy work together.
Common Mistakes That Break Tracking
These are the problems we find most often when we review tracking for local businesses:
- Installing GA4 twice, once directly and once through Tag Manager, which doubles every visit
- Also, forgetting to publish the container after making changes
- Tracking page views but not form submissions or calls
- Counting your own team’s visits as customer visits
- Finally, never checking the reports after setup
Fixing these usually gives you a much clearer picture straight away. In addition, accurate tracking makes your Google Ads campaigns far easier to improve.

Frequently Asked Questions
Is Google Tag Manager free?

Not strictly, but it makes life easier. For example, a Google Tag Manager setup lets you add form, call and ad tracking without editing your website each time.
How long does it take to set up?
A basic setup can be done in an afternoon. However, tracking every important action and testing it properly usually takes longer.

Yes. During your Google Tag Manager setup, you can track clicks on your phone number, which shows how many mobile visitors call you.
