Tag Sequencing in Google Tag Manager
What is Tag Sequencing?
Asynchronous tag firing often leads to unpredictable outcomes. Tag sequencing in Google Tag Manager (GTM) ensures that tags execute in a specific order, creating a well-organized process for reliable data collection [2][4].
Using the Advanced Settings in GTM, you can configure tags to fire before or after a primary tag and decide how to handle any failures in the sequence. While sequencing ensures dependencies are followed, tag priority addresses conflicts when multiple tags need the same resources [3]. This distinction is crucial for maintaining accurate data and smooth tracking.
For SaaS and eCommerce businesses, this precision ensures that marketing and analytics tools work without interruptions, enabling clear and actionable insights. When set up correctly, tag sequencing minimizes issues like data gaps, incorrect attribution, and overlapping tag execution.
This method not only guarantees accurate tracking but also helps you avoid common problems with data collection, as we'll dig into further.
Why Tag Sequencing Matters
Tag sequencing plays an important role in maintaining accurate data, adhering to privacy laws, and tracking marketing performance effectively.
Accurate and Reliable Data
Proper sequencing ensures that each tag collects the right data at the right time. Without it, tags may fire out of order, leading to incomplete or incorrect data. For instance, critical information could be missed if a dependent tag doesn't execute as expected [1][2].
Privacy Compliance
By ensuring consent-related tags fire first, sequencing helps prevent data collection that could violate privacy laws like GDPR and CCPA [3].
Improved Marketing Tracking
When multiple tools or tracking pixels are used, sequencing ensures proper marketing attribution and conversion tracking. This is especially crucial for SaaS and eCommerce businesses, as it enables accurate tracking and optimizes returns on marketing campaigns.
| Aspect | Without Sequencing | With Sequencing |
|---|---|---|
| Data Collection | Events may be missed | Systematic and complete |
| Attribution | Risk of errors | Accurate user journey tracking |
| Error Handling | Uncontrolled failures | Managed and predictable |
Technical Advantages
Using GTM callbacks, tag sequencing efficiently chains tags and resolves dependencies, addressing common technical challenges that might otherwise compromise data quality.
Avoiding Conflicts
When tags compete for resources or need access to the same data, sequencing establishes a clear order of execution, preventing conflicts [2].
Now that you understand why sequencing is so important, let’s dive into how you can set it up effectively in GTM.

These benefits are especially important for businesses with complex tracking needs or sensitive user data, where the correct order of tag execution is essential to maintain data quality.
Now that you know who benefits from tag sequencing, let's dive into how to set it up effectively in GTM.
Core Steps and Setup for Tag Sequencing
Setting up tag sequencing in Google Tag Manager (GTM) requires attention to detail to ensure data accuracy. Here's a breakdown of how to get it right.
Key Components
Tag sequencing revolves around three main parts: Setup Tags (to prepare data), Main Tags (to handle primary tasks), and Cleanup Tags (to manage post-execution processes).
How to Set It Up
To enable tag sequencing in GTM, head to the Advanced Settings tab in your main tag's configuration. Under the Tag Sequencing section, you'll have the option to define both setup and cleanup tags.
Handling Dependencies and Custom Tags
For scenarios like tracking eCommerce transactions, a setup tag might first gather product details, which the main tag then sends to your analytics platform. If you're using custom HTML tags, you'll need to include callbacks to signal when the tag execution is complete, ensuring the sequence runs smoothly [2].
Using the Data Layer and Managing Success
Keep in mind, the data layer remains static during an event and only updates after the next push. Plan your sequences with this in mind. Cleanup tags offer flexibility - they can be triggered only after a successful execution or regardless of the outcome, which is useful for managing errors [1][3].
Why Tag Sequencing Matters
Tag sequencing ensures that tags fire in the right order, respecting dependencies. This is especially important in complex setups where maintaining data quality is critical.
Now that the setup basics are covered, we’ll dive into real-world examples to show how tag sequencing can improve tracking accuracy.
Key Parts of Tag Sequencing
Tag sequencing in Google Tag Manager involves three main components that work together to ensure data is collected correctly and tracking runs smoothly.
Setup Tags
These tags get everything ready by gathering data, initializing variables, and checking conditions for the main tag to run. For instance, in ecommerce tracking, a setup tag collects details like product data, pricing, and transaction IDs before passing it to the main analytics tag.
Main Tags
Main tags handle the core tracking tasks once the setup tags have done their job. These tasks include:
- Sending data to analytics tools
- Activating conversion tracking pixels
- Running marketing automation scripts
- Processing ecommerce transactions
Cleanup Tags
Cleanup tags take care of everything after the main tags finish. They clear temporary data, reset variables, and handle errors to make sure future tags work without issues.
| Tag Type | Function | Timing | Use Cases |
|---|---|---|---|
| Setup | Prepares data | Before Main Tag | Data collection |
| Main | Executes actions | After Setup Tag | Analytics, conversions |
| Cleanup | Finalizes process | After Main Tag | Error handling, resets |
For SaaS and ecommerce platforms, these components help track user activity, ensure accurate attribution, and stay compliant with privacy laws. If you're using custom HTML tags, JavaScript callbacks are essential to keep communication between tags smooth [2].
To keep things running efficiently, make sure each tag finishes its task before the next one starts. This is especially important when working with third-party tools like CRMs or marketing automation platforms, where data accuracy is critical [1][3].
Now that these components are clear, let’s explore how to set up tag sequencing in GTM for real-world scenarios.
How to Set Up Tag Sequencing
Setting up tag sequencing in Google Tag Manager (GTM) ensures that your tags fire in the right order for accurate data collection. Here's a step-by-step guide to get it done:
- Access Advanced Settings: Open your main tag in GTM and find the Advanced Settings section.
- Enable Setup and Cleanup Tags: In the Advanced Settings, check the options to fire a setup tag before and/or a cleanup tag after the main tag. Choose the appropriate tags from the dropdown menus.
- Configure Timing: Make sure setup tags finish before the main tag fires, and cleanup tags execute only after the main tag completes its task [1].
For custom HTML tags, use callbacks to control the sequence. This is especially useful for analytics setups that require specific data to be available at the right time [2].
| Tag Type | Purpose |
|---|---|
| Setup Tag | Prepares the necessary data |
| Main Tag | Executes the primary tracking |
| Cleanup Tag | Handles post-processing tasks |
When dealing with multiple tags, use tag priority settings to control the execution order. This is particularly helpful for:
- Accurate eCommerce tracking
- Ensuring privacy compliance
- Collecting marketing attribution data
- Analyzing user journeys
Setup tags prepare the data, main tags handle the core tracking, and cleanup tags take care of any final processing. For more details on these tag types, check the earlier "Core Steps and Setup" section [3].
If you're using several tracking tools, prioritize tags based on their dependencies to keep your data accurate [4].
Next, let’s look at an example of how tag sequencing works in practice.
Example: Using a Setup Tag for Better Data
Let’s dive into an eCommerce example to highlight how sequencing tags can improve data collection accuracy.
In eCommerce tracking, a setup tag collects dynamic product details - like price, SKU, inventory status, and discounts - from the data layer before the main tracking tag activates. This ensures your analytics platform gets accurate, real-time data.
Here’s how the process typically works:
| Stage | Action | Data Collected |
|---|---|---|
| Setup Tag | Scans product page | Price, SKU, inventory status |
| Main Tag | Sends to analytics | Complete product details |
| Cleanup Tag | Clears temporary data | Removes cached values |
For custom HTML tags, you’ll need these essential GTM variables:
- Container ID
- HTML ID
- Callback functions
This method ensures accuracy, especially for businesses dealing with dynamic pricing or frequently updated product details [2][3]. The setup tag ensures that the data is ready and complete before the main tag sends it to your analytics platform.
When implementing, double-check that the setup tag finishes its job before the main tag triggers. This prevents errors like incomplete or incorrect data being sent [3].
With this example in mind, let’s move on to more tips for improving tag sequencing in GTM.
Best Practices for Tag Sequencing
When using GTM, setting up tag sequencing requires thoughtful planning to ensure your data is collected accurately. Here’s how to keep your data on track.
Define Tag Dependencies
Make sure tag dependencies are clearly outlined. For instance, fire the transaction data collection tag before sending data to your analytics platform. This prevents incomplete or incorrect data from being sent [1].
Set Tag Priorities Strategically
| Priority Level | Tag Type | Purpose |
|---|---|---|
| High (1-3) | Core tracking tags | Tracks essential analytics and conversions |
| Medium (4-6) | Enhanced tracking tags | Gathers additional data for deeper insights |
| Low (7-10) | Supporting tags | Manages extra features or third-party tools |
Leverage the Data Layer
Always confirm that your data layer variables are fully populated before firing tags that depend on them. This is especially important when working with dynamic content [2].
Add Error Handling Measures
Prepare for potential failures by setting up error handling. Configure key tags to retry their execution or use fallback values to reduce the risk of losing data [3].
Keep an Eye on Tag Performance
After setting up your tag sequence, monitor it regularly. Use GTM’s preview mode to check firing order, data availability, timing, and any errors. This ensures everything is running smoothly.
Handle Custom HTML Tags Properly
If your sequence includes custom HTML tags, make sure callbacks are implemented correctly to avoid issues [2].
"Tag sequencing is particularly useful when dealing with tags that have dependencies on other tags for data collection or processing. Understanding these dependencies is crucial for maintaining data accuracy." [2][3]
Use Firing Rules to Improve Accuracy
Firing rules play a key role in tag sequencing, ensuring tags run only under the right conditions and in the proper order.
Set Specific Trigger Conditions
Define clear triggers based on events or variables. For example, fire a purchase tag only when both the transaction ID and purchase amount are present in the data layer.
| Condition Type | Purpose | Example Rule |
|---|---|---|
| Page-Based | Fire tags on specific pages | URL contains /checkout/ |
| Event-Based | Trigger based on user actions | Form submission complete |
| Data Layer | Ensure required data is available | Transaction data present |
| Custom Variables | Check for specific values | User login status = true |
Use Sequential Logic
Tags should fire in a logical order. For instance, ensure prerequisite tags execute before dependent tags. This maintains data accuracy and avoids incomplete information being sent to analytics tools [1].
Manage Dynamic Content
When dealing with dynamic content, make sure essential elements are loaded before triggering tags. Use JavaScript variables or DOM-ready triggers to delay execution until all necessary data is available [2].
Track Rule Performance
Pay close attention to:
- Timing of triggers
- Data layer readiness
- Tag execution order
- Identifying and fixing errors
Once firing rules are properly configured, the next step is to test and debug your setup to ensure everything works smoothly.
Test and Debug Your Setup
Thoroughly testing your tag sequences before deployment is key to ensuring accurate data collection. Google Tag Manager's (GTM) preview mode is your go-to tool for spotting and fixing sequencing problems early.
Monitor for Potential Problems
GTM's preview mode lets you track tag execution in real-time. Keep an eye on:
- The order in which tags fire and their timing
- Values in the data layer at each stage
- Any error messages or warnings that pop up
Frequent Sequencing Problems
Pay close attention to these common issues during testing:
| Issue Type | What to Check | How to Verify |
|---|---|---|
| Timing Conflicts | Tags firing at the same time | Use the preview timeline |
| Data Availability | Ensure required variables are present | Check the data layer state |
| Dependencies | Confirm setup tags run before main tags | Verify execution order |
| Priority Conflicts | Resolve competing tags | Review tag priority settings |
How to Test Step by Step
To test your sequences effectively, follow these steps:
- Verify that setup tags are in place and working correctly.
- Check that the data layer is ready and contains the needed information.
- Validate the execution of main tags and ensure firing rules and triggers work as intended.
This approach ensures tags fire under the correct conditions without conflicts.
Use Debug Tools and Keep Records

Set Tag Priority Carefully
Tag priority in Google Tag Manager (GTM) helps resolve conflicts when multiple tags are triggered at the same time. While sequencing ensures tags fire in the correct order, priority assigns a numerical value to determine which tags take precedence. Higher numbers mean higher priority.
Priority Values and Key Scenarios
Use priority values strategically based on the importance of each tag:
| Tag Type | Recommended Priority | Why It Matters |
|---|---|---|
| Core Analytics | 10+ | Ensures baseline tracking is established first |
| Data Collection | 5-9 | Gathers user data needed for dependent tags |
| Marketing Tags | 3-4 | Relies on core analytics and user data |
| Third-party Scripts | 1-2 | Non-essential, can execute last |
For example, analytics tags should fire before marketing tags to ensure consistent data collection. Similarly, user data should be captured early to support other processes.
Performance and Common Mistakes
Be cautious when assigning priorities. Giving high priority to too many tags can negatively affect performance. Reserve top priority values for tags that are absolutely critical.
Common mistakes to avoid:
- Assigning the same high priority to multiple tags
- Using high priorities for tags that aren't essential
- Ignoring dependencies between tags that share data
- Overlooking how priorities impact page load performance
Keep in mind that tag priority complements sequencing but serves a different purpose. Sequencing establishes direct dependencies between tags, while priority manages simultaneous triggers.
Once priorities are properly assigned, you can focus on refining sequencing for more complex setups and ensuring everything runs smoothly.
Advanced Topics in Tag Sequencing
Now that we've covered the basics, let's dive into some advanced techniques for managing complex tag sequencing in Google Tag Manager (GTM).
Custom HTML Tags in Sequences
When working with custom HTML tags, it's essential to include callback methods to signal when a tag has finished executing. Here's an example:
<script>
// Your custom code here
window.dataLayer = window.dataLayer || [];
dataLayer.push({'event': 'customTagComplete'});
</script>
This ensures subsequent tags in the sequence know when to proceed.
Advanced Sequencing Patterns
- Dynamic Data Collection: Use tags to gather specific data points - like product SKUs, prices, or user preferences - before triggering dependent tags. This ensures all necessary data is available for analytics and marketing purposes [2].
- Asynchronous Handling: Manage tags that run simultaneously by leveraging GTM's Container ID and HTML ID variables. This helps maintain the correct firing order for your tags [2].
- Error Recovery: Add error handling to preserve data quality when a tag fails. For example, push error details to the data layer so they can be monitored and debugged effectively.
Performance Optimization
To keep your sequences running smoothly, focus on these performance factors:

Setting Up Custom HTML Tags
To ensure your custom HTML tag signals completion to GTM, include the following structure in your code:
<script>
// Run your custom tracking or functionality
function customFunction() {
// Add your custom code here
}
// Notify GTM of completion
window.dataLayer = window.dataLayer || [];
dataLayer.push({'event': 'customTagComplete'});
</script>
Key Steps for Custom HTML Tag Sequencing
When working with custom HTML tags, keep these steps in mind:
- Data Dependencies: Ensure data layer variables or outputs from earlier tags are available.

How the Data Layer Affects Sequencing
The data layer plays a key role in controlling tag sequencing in Google Tag Manager (GTM). It ensures tags fire in the right order, which is essential for accurate tracking and proper execution.
Data Layer Push Events and Tag Timing
The dataLayer.push() method updates the data layer with information that triggers tags. Timing these updates correctly is critical to ensure tags that depend on specific data execute as intended.
Here’s how different scenarios impact tag sequencing:
| Scenario | Effect on Sequencing | Best Practice |
|---|---|---|
| User Interaction Events | Fires tags based on user actions | Push event data before triggering dependent tags |
| Form Submissions | Tracks form data for conversions | Push form data to the data layer before firing conversion tags |
Managing Data Dependencies
When dealing with tag sequences that rely on data from the data layer, managing these dependencies is key. For example, in ecommerce tracking, product details like SKU or price should be sent to the data layer before triggering purchase-related tags.
dataLayer.push({
'event': 'productView',
'productData': {
'id': 'SKU123',
'price': 99.99
}
});
Troubleshooting Data Layer Sequences
To ensure tags fire as expected, focus on these areas:
- Event Timing: Confirm that
dataLayer.push()events occur in the correct order. - Data Availability: Check that required variables are available in the data layer before firing dependent tags.
