Google Tag Manager and Google Tag Assistant
Are used together to manage and troubleshoot tags effectively. Google Tag Assistant is a troubleshooting tool that helps verify the implementation and functionality of tags on your website, while Google Tag Manager is used to manage and deploy tags from Google products and third parties.
Google Tag Manager (GTM) offers a feature called Preview and Debug mode, which allows you to test and validate changes to your tracking and analytics setup before deploying them live on your website. This mode acts as a sandbox where you can experiment with tracking configurations without impacting real user data.

Google Tag Assistant
For troubleshooting Google Tag Manager issues, Google Tag Assistant is recommended as it provides detailed diagnostics and allows you to debug your website, including iframes, within a single session. It also includes a side panel that allows you to see and check all the tags firing on your page and can help identify issues such as missing or duplicated tags, incorrect tag configurations, and data discrepancies.
To troubleshoot issues, you can use the Tag Assistant Chrome extension to analyze tags on your domain, troubleshoot tags on your site, and verify their implementation and functionality. Additionally, you can use Google Tag Manager's Preview and Debug mode for more in-depth testing and validation of your tags and triggers.
In summary, while both tools are essential, Google Tag Assistant is particularly useful for troubleshooting and verifying the implementation of tags, making it the best tool for this specific purpose
