How to set up basic tags

Setting up tags through Google Tag Manager simplifies the process of integrating analytical and marketing tools. This tool allows you to quickly and effortlessly implement tracking of key events on the site, such as clicks, form submissions or page transitions. If you need to set up analytics or order SEO promotion of the site, we are ready to help you set up GTM to effectively track user actions and receive accurate data to optimize your site.

Setting up Google Analytics with GTM

Google Analytics is a key tool for analyzing traffic and user behavior data. Setting up this tag through Google Tag Manager greatly simplifies the process.

Create a Google Analytics tag:
Open Google Tag Manager and go to the Tags section.
Click Create and choose a tag type: Google Tag.
In the Tracking type section, select Page view.

Add a tracking ID: in the Google Analytics Tag Settings field, enter the tracking ID (for example, G-XXXXXXXXXXXXXX) that can be found in your Google Analytics account.

Set up a trigger:
- Click on the Triggers field and select All Pages. This ensures that data is collected from all pages of the site.

Save and test:
- Save the tag and turn on the preview mode in GTM to make sure the tag works correctly.
Publish the changes:
- After successful testing, publish the container.

Set up events (clicks, form submissions)

Events in Google Analytics allow you to track key user interactions, such as button clicks, form submissions, and file uploads.

Create a trigger for an event:
Go to the Triggers section of google gtm and create a new trigger.
Choose the type of trigger, for example, "Click - link only" or "Form submission".
Specify the trigger condition. For example, for a button, you can use a condition where the link text or CSS selector matches the button.

Add a tag for the event:
- Create a new tag like Google Analytics: Universal Analytics.
- Specify the name of the event
- Data stream identifier

Bind a trigger to a tag:
- In the Triggers section, select the trigger you created and attach it to a tag.

Checking the performance:
- Test your event through the preview mode and make sure it shows up in Google Analytics.

Setting up tags for the Facebook pixel

The Facebook pixel is used to track conversions, set up retargeting, and analyze advertising campaigns. It is easy to set it up through Google Tag Manager.

Get the pixel code:

Log in to Facebook Ads Manager and go to the Pixels section.
Copy the pixel code that starts with fbq.

Create a tag for the pixel:

In Google Tag Manager, create a new tag and select the Custom HTML type.
Paste the pixel code into the text box.

Add a trigger:

Attach an All Pages trigger to make the pixel load on all pages.

Setting up events:

To track specific events (such as add to cart), add additional lines to the pixel code:

javascript

CopyEdit

fbq('track', 'AddToCart');

Checking and testing:

Use the Facebook Pixel Helper browser extension to make sure the pixel is working correctly.

Publishing:

After testing, publish the container.

Advanced features of Google Tag Manager

Google Tag Manager (GTM) provides tremendous opportunities to improve analytics and marketing, especially when used to integrate with other tools, automate tasks, and set up complex scenarios.

Integration with other analytics and marketing tools

Connecting Google Ads through Google Tag Manager allows you to effectively track conversions and user interactions with your website. The essence of the integration is to create a special tag that will record actions that are important for your advertising campaign, such as filling out a form or completing a purchase. For example, if you want to track applications submitted through a form, GTM will transmit data about this action directly to Google Ads, which will ensure transparency and accuracy of analytics.

Hotjar is a tool for visual analysis of user behavior that provides heatmaps, click maps, and session records. Implementing the Hotjar tracking code through Google Tag Manager greatly simplifies the process, as all the code is placed centrally. This allows you to activate the tool on all pages of your website or only on certain ones, depending on the trigger settings. For example, you can use Hotjar to analyze how users interact with an application form or a specific page.

Facebook Pixel through GTM makes it easier to retarget and track key events, such as page views, adding products to the cart, or completing a purchase. This is especially useful for personalized advertising campaigns, as the pixel captures user behavior and transmits data to the Facebook advertising platform. Configuring the pixel through GTM allows you to centrally manage its code and flexibly adapt its work to your tasks.
Implement microtagging with Google Tag Manager
With Google Tag Manager, you can easily implement micro-markup on your website even if you don't have access to the source code. This is especially useful for adding Schema.org structured data to improve your site's display in search engine results.
Example: Implementing micro-markup for case studies
Let's say you want to add Schema.org micro-markup to your project (case) cards so that search engines display additional data such as title, date, meta tags, images, etc.
Solution via GTM:
Create a custom HTML tag that embeds the micro-markup code. For example:

Use variables in GTM to dynamically populate data:

{{Product Name}}: The name of the product.
{{Product Image URL}}: The URL of the image.
{{Product Description}}: Product description.
{{Product SKU}}: Unique product code.
{{Product URL}}: Link to the product.
{{Currency}}: Currency.
{{Product Price}}: Price.
{{Product Availability}}: Availability status (for example, InStock or OutOfStock).

The introduction of different types of variables can be implemented through the GTM

These variables can be added using functions to display content. For example, we need a description variable, a function that can be used:

function() {

var metaDescription = document.querySelector('meta[name="description"]');

return metaDescription ? metaDescription.getAttribute('content') : 'Не вказано';

}

The settings are as follows:

An example of a variable for a URL:

You can also make a variable with unique CSS, for example, to track page titles

Add these variables to the microdata code itself

Set up a trigger to launch the tag:
- For example, a Page View trigger for product card pages.

Create complex conditions for triggers

Sometimes you need a tag to be triggered only when several conditions are met simultaneously.

Example: Setting up click tracking on the "Buy" button, but only if the user came from an advertising campaign.

Solution:

Create a trigger of type "Click" with conditions:

CSS selector of the button: for example, dp-button.

Source of traffic: utm_source = google_ads.

Configure the tag associated with this trigger.

Result: The trigger is fired only when the user clicks on the button after leaving the ad.

Automate tasks with GTM

GTM helps automate the transfer of data to CRM systems, analytics platforms, and advertising networks.

Example: Automatically send data about form completion to CRM.

Create a custom HTML tag:

fetch('https://your-crm-api.com/data', {

method: 'POST',

headers: {

'Content-Type': 'application/json'

body: JSON.stringify({

'name': '{{Form Name}}',

'email': '{{Form Email}}'

})

});

Configure the Form Submission trigger to activate the tag.

Result: Data from the form is automatically sent to CRM.

Using variables for dynamic data

We've already talked about this above, but there's one more useful thing about variables. Because variables allow you to pass dynamic values to tags and triggers, and you want to keep track of the product ID that the user added to the cart. With the help of the dataLayer variable, you can do this easily and efficiently.

Track product ID when adding to cart

dataLayer.push({

'event': 'addToCart',

'productId': '{{Product ID}}',

'productName': '{{productId}}'

});

The values specified by {{Product ID}} and {{productId}} can be created in variables (as described above)

Result: Each addition of a product to the cart is recorded in the analytics with its ID.

Setting up eCommerce tracking

For online stores, it is important to track transactions, buyer behavior and actions in the cart. This helps to optimize the shopping process and improve the user experience. If you are interested in effective analytics or SEO for online stores to increase sales and profits, we are ready to implement Google Tag Manager and other tools to ensure your business gets maximum results.

Steps:

Enable eCommerce tracking in Google Analytics.
Transfer transaction data via dataLayer:

dataLayer.push({

'event': 'purchase',

'transactionId': '{{Idtransactio}}',

'transactionTotal': {{sum}},

'products': [

{

'id': '{{Id}}',

'name': '{{ProductName}}',

'price': '{{price}}',

'quantity': '{{quantity}}'

}

]

});

purchase - defines the type of event that occurred. In this case, 'purchase' means that the user made a purchase.
{{Idtransactio}} is a unique transaction identifier. It is needed so that each purchase is recorded as a separate event in the analytics.
{{sum}} - the total amount of the transaction. It includes the cost of all products, taxes, shipping, and any discounts.
{{Id}} - unique product identifier
{{price}} - the price per unit of the product
{{quantity}} - the number of purchased units of this product.

Set up a tag in GTM to send this data to Google Analytics. And you'll see sales and product data right in your Google Analytics reports.

Google Tag Manager's advanced features allow you to integrate data from multiple sources, automate tasks, improve analytics, and create complex scenarios. These tools help you gain a deeper understanding of your audience and optimize your marketing campaigns. If you need to customize GTM for more complex tasks, don't hesitate to contact our experts!

Combine data from multiple sources

One of the key advantages of Google Tag Manager is the ability to integrate data from different platforms. This allows you to create a complete picture of user behavior by combining data from websites, mobile applications, and CRM systems.

How to combine data from different sources?

Use DataLayer. DataLayer allows you to transfer data from external systems directly to GTM. For example, you can send transaction data from your CRM system.
Integration with analytical tools. GTM manager supports integration with Google Analytics, Facebook Pixel, and other data platforms.
Using the API. For complex scenarios, you can use custom HTML and JavaScript tags to connect GTM with external data sources.

Customize conversions based on multiple stages

For tracking complex sales funnels and user interactions at different stages, the flexibility provided by Google Tag Manager is important.

Tracking complex sales funnels:

Separate the stages of the funnel. Identify the key stages: product preview, add to cart, checkout, and purchase.
Create triggers. Set up triggers for each step. For example:

The "View Product" event is activated when the product page is loaded.
The "Add to cart" event is triggered by clicking on the corresponding button.
Go to the checkout page
Go to the successful checkout page

Setting up triggers for each stage of interaction:

URL-based triggers. Use page URLs (page pattern, for example, product) to determine the stage of the funnel.
Event triggers. Track clicks, form submissions, or link clicks. For example, a click on the "Add to cart" button using the unique CSS of this button
Then go to the checkout page. Usually, such pages have a pattern. For example.

Next, you go to the successful order page. The online store usually takes the user to a separate page with the order number

After setting up all the stages in GTM, the data will be sent to Google Analytics for analysis. In Google Analytics, set up an event report to see how users go through each stage.

If a customer adds a product to the cart but doesn't complete the purchase, you can set up a trigger that will send an event to Google Ads for retargeting.

Track interactions with files

Tracking file downloads, such as PDFs, images, or presentations, is essential for measuring user engagement and collecting data on interactions.

How do I set up download tracking for PDFs, images, and other documents?

Create a trigger based on clicks.
Open the triggers section in google gtm and create a new trigger.
Select the type "Click - link only".
Customize the condition: URL contains ".pdf", ".jpg", ".docx" and other file extensions.
Add a Google Analytics tag.
Create a Google Analytics tag to track events.
Enter the Analytics ID and the name of the event
Check if the trigger is working.
Turn on the preview mode in Google Tag Manager.
Check if the trigger is triggered when you click on the file.

Benefits of tracking file interactions:

Understanding which resources are most in demand by users.
Assessment of audience engagement.
The ability to improve content based on the data obtained.

These additional features of Google Tag Manager allow you to manage your data more efficiently, improve your analytics, and build successful marketing campaigns. If you want to set up complex scenarios such as tracking file downloads or sales funnels, our experts are here to help!

Errors and fixes when working with Google Tag Manager

Errors when working with Google Tag Manager (GTM) can lead to incorrect data transfer, incorrect event triggering, or even website crashes. Let's take a look at the most common issues and how to fix them.

Incorrect installation of the GTM code

The GTM code must be installed on all pages of the site in strictly defined places. If it is placed incorrectly, it can prevent tags from being triggered or data from being transferred to analytics systems. For example, if the code is inserted only in the header of the site but not in the body, some events may be missed.

This problem often occurs if the code is inserted manually and not through a CMS or special plugins. Sometimes the code is duplicated, which leads to double submission of data to Google Analytics or other systems.

Tag conflicts

When multiple tags are configured to perform the same task, it can lead to incorrect website or analytics behavior. For example, if two tags send the same event to Google Analytics, it will result in duplicate data. Also, conflicts can cause your site to slow down.

How to fix it:

To prevent conflicts, audit all configured tags. Make sure that each tag performs its own task and uses a unique trigger. If two tags could potentially be triggered at the same time, add exception conditions. For example, you can configure one tag to run only on a specific page and the other to run on all other pages.

How to configure tags correctly

Even if you set up your tags correctly, errors can occur, so it's important to test them before publishing. GTM provides a preview mode that allows you to see which tags have been triggered, which triggers have been activated, and what data is being transmitted.

For deeper diagnostics, you can use browser extensions such as Google's Tag Assistant. This tool will show you errors in tag setup, duplicate data, and other issues.

Recommendation:

Enable the preview mode in GTM to see how tags work in real time. This will allow you to identify tags that are not working or errors in their configuration.
After testing, publish the changes and test them again on the live site to make sure everything works correctly.

Errors in GTM are often due to human error or technical limitations. Regular testing, careful review of configurations, and the use of debugging tools will help you avoid problems and make your data accurate and useful.

Tips for beginners and advanced users of Google Tag Manager

Working with Google Tag Manager (GTM) requires care and a structured approach. Even experienced users can run into problems if they don't follow the basic rules. Here are some useful tips to help both beginners and advanced users avoid mistakes and increase work efficiency.

Test tags before publishing

Why it's important: Without testing, you can accidentally publish incorrect tags that can:

Lead to the transfer of incorrect data to analytics systems.
Disrupt the operation of the website (for example, slow down page loading).
Disrupt advertising campaigns.

Test tags across all scenarios, including different devices (desktop, mobile), browsers, and versions. This ensures that the tags work universally.

Use versions to control changes

Why it matters: Every change in GTM can affect the way tags, triggers, and variables work. If you make a mistake, it will be difficult to revert to the previous settings without saved versions.

For large projects or teamwork, set internal rules so that all changes to GTM are documented. This will simplify data recovery and improve communication between team members.

Follow a structure to organize tags, triggers, and variables

Why it's important: When you configure many tags, triggers, and variables in GTM, a lack of structure can lead to confusion. The result:

It will be difficult to find the elements you need.
There is a risk of duplicate settings or conflicts between tags.

Make a list of naming standards for tags, triggers, and variables

These tips will help you work with GTM efficiently and minimize the risk of errors. Continuous testing, versioning, and maintaining a structure not only make working with Google Tag Manager easier, but also make the settings clear to all team members if you're working on a project together.
