How to Use Google Tag Assistant: A Simple Tutorial for Website Owners
Ever wondered if your website tags are working correctly? As website
owners, we often install various tracking codes but rarely verify if
they're functioning properly.
That's where Google Tag Assistant comes in. This powerful Chrome browser extension helps us verify, install, and troubleshoot the implementation of Google tags on our websites. Specifically designed for monitoring tags like Google Analytics, Google Ads, and Google Tag Manager, this tool gives us a clear picture of what's happening behind the scenes.
When we click on the extension icon, Tag Assistant immediately shows us which tags are present on our page and their status. In fact, it uses a color-coded system with four different states: gray (no codes found), red (problematic implementation), blue (working but could be improved), and green (optimally installed).
Additionally, Tag Assistant lets us troubleshoot our website by navigating through different pages while seeing exactly which events and data are being collected by those tags. If we encounter connection issues, the tool also provides troubleshooting suggestions to get things working again.
In this guide, we'll walk through everything you need to know about using Google Tag Assistant effectively - from installation to advanced features - ensuring your website's tracking is working exactly as intended.
Installing Google Tag Assistant
Getting started with Google Tag Assistant requires a simple installation process. The tool has undergone significant changes recently, making it more powerful and user-friendly.
Download the Tag Assistant Chrome extension
Installing Tag Assistant takes just a few clicks:
Visit the Chrome Web Store and search for "Tag Assistant" or go directly to the extension page
Click the Add to Chrome button
Confirm by clicking Add extension when prompted
This unified extension helps you install, troubleshoot, and verify the implementation of Google tags on your website [1]. Moreover, it supports debugging websites across multiple windows and tabs, making your testing process more efficient.
Enable the extension in your browser
Once installed, you'll need to enable Tag Assistant:
Pin the extension to your browser toolbar by clicking the Extensions icon and then the pin icon next to Tag Assistant
Click the Tag Assistant icon in your toolbar
Click Enable to activate the extension on the current page
After enabling, Tag Assistant immediately begins scanning for Google tags on your webpage. Furthermore, you can click "Troubleshoot" to activate debug mode using tagassistant.google.com [2].
Difference between Tag Assistant Legacy and Companion
Previously, Google offered two separate extensions: Tag Assistant Legacy and Tag Assistant Companion. However, following significant user feedback, Google reversed its decision to deprecate these tools [3]. Instead, they've merged both into a unified extension with enhanced capabilities.
If you're currently using Tag Assistant Legacy, there's no need to uninstall anything—it will automatically update to the new Tag Assistant [1]. For users of Tag Assistant Companion, the extension will be automatically uninstalled once Tag Assistant is updated [4].
The unified Tag Assistant streamlines the debugging process, reducing downtime and ensuring that campaigns are measured accurately [3]. Although the Tag Assistant Companion will still work for some time, it will be fully deprecated in 2025 [4].
This consolidation simplifies the troubleshooting process while preserving all the functionality website owners rely on to verify their Google tags are functioning correctly.
Connecting Tag Assistant to Your Website
After installing Tag Assistant, the next crucial step is connecting it to your website for monitoring and debugging. This connection establishes a communication channel between your site and the Tag Assistant tool.
How do I connect to my website with Tag Assistant?
Connecting Tag Assistant to your website is straightforward:
Navigate to tagassistant.google.com
Click the Add domain button
Enter your website's URL (including "https://" or "http://")
Click Connect
Once connected, Tag Assistant will display all Google tags found on your website. If no tags appear, you may need to check your implementation or consult the Tag Manager help center for troubleshooting tips.
Using the debug parameter for deeper analysis
During the connection process, Tag Assistant adds a debug parameter (_dbg) to the end of your URL. This parameter serves several important purposes:
Enables viewing events in other debugging surfaces like Google Analytics' DebugView
Makes establishing the debugging channel more reliable on modern browsers
Helps identify which tags fire and whether they capture expected data
For sites sensitive to URL parameters, you can uncheck "Include debug signal in the URL" option, though this may reduce connection reliability.
Navigating your site while connected
The debug window remains active as you browse through your website, provided you stay within the same domain and pages contain Google tags. Throughout your navigation:
A preview badge appears in the bottom corner of your page
Tag Assistant updates in real-time with information about your tags
You can test user interactions such as form submissions or conversion funnels
Events appear in the left sidebar of the Tag Assistant interface
To disconnect, simply click Stop Debugging or the X in the upper left corner of the debug window. You can choose whether to keep the domain enabled for future debugging sessions or completely sever the connection.
Using Tag Assistant to Monitor and Troubleshoot Tags
Once connected to your website, Tag Assistant becomes a powerful monitoring and troubleshooting tool. Let's explore how it helps ensure your tags are working correctly.
How does Tag Assistant work?
Tag Assistant identifies, validates, and troubleshoots Google tags installed on your web pages. Upon scanning a page, it displays all detected Google tags including Google Analytics, Google Ads, and Google Tag Manager. For each tag, it provides validation status and detailed diagnostic information.
The Troubleshoot button activates debug mode, opening a detailed interface where you can view events, data layer information, and sent hits. This interface updates in real-time as you navigate through your site, displaying a chronological list of events on the left side and detailed information about selected events on the right.
Understanding tag states: red, blue, green, gray
Tag Assistant uses a color-coded system to indicate tag status:
Green: All identified Google tags are perfectly valid
Blue: Tags have no major issues but use non-standard implementation
Yellow: Tags have minor implementation issues
Red: Tags have major implementation issues
Gray: No Google tags detected on the page
A number in the middle of the Tag Assistant icon indicates how many Google tags were found on the page.
Viewing tag details and errors
Clicking on a specific tag reveals comprehensive information about its implementation. The interface shows:
The tag's configuration details
JavaScript used to configure data for the event (gtag() calls or dataLayer.push())
Hits sent to various endpoints
Current state of the data layer
Errors or warnings detected
Using the 'Where to Optimize' section
The 'Where to Optimize' section highlights specific issues with tag implementation and provides guidance for fixes. It displays:
What exactly is wrong with the tag
Links to relevant help articles
Suggestions for implementation improvements
Common issues and how to fix them
Several common issues appear in Tag Assistant diagnostics:
Missing or invalid account IDs: Ensure all IDs are correctly entered
Duplicate tags: Remove redundant implementations causing data distortion
Tags loading too late: Move tag code higher in your page structure
Missing consent for EEA users: Implement proper consent mechanisms
Config command out of order: Ensure gtag config commands precede event commands
For each issue, Tag Assistant typically provides specific error messages alongside practical suggestions for resolving them.
Advanced Features: Recording and Sharing Sessions
Beyond basic tag verification, Tag Assistant offers powerful recording capabilities for comprehensive website analysis.
What is the recording function?
The recording function primarily captures a complete browsing session across multiple pages, tracking all tags that fire during your journey. This feature enables you to analyze firing sequences and identify potential conflicts without manually checking each page individually. Essentially, all activities are logged chronologically, making it easier to spot errors affecting your Google Analytics data.
How to start and stop a recording
To begin recording:
Click the Tag Assistant icon in your Chrome toolbar
Select the blue Record button
Navigate through your website pages as needed
The icon color may change if errors are detected
To stop recording, click Cancel recording
Viewing the full report and session summary
After stopping, click Show full report to access a detailed analysis. The report contains:
Recording summary with tracked pages and tags found
Chronological page loads with timestamps
Detailed tag information for each page
Options to resume recording if needed
Sharing debug sessions with others
Notably, Tag Assistant makes collaboration simple:
Go to tagassistant.google.com
Navigate your website to populate debug information
Click the overflow menu (three dots) > Export session or Share
For sharing: review settings and copy the generated link
For exporting: click Export to download the session file
Consequently, teammates can import your session or use your shared link to help troubleshoot issues.
