Prepare for Google Tag Manager Publishing QA Quiz for Beginners
Use this short review before the quiz if you want to check the GTM QA habits that reduce tracking mistakes before publishing.
Preview before publishing
Preview mode lets you test container changes before they go live. It helps confirm which tags fired and which tags did not.
- Use preview mode before publishing important changes.
- Test the real user action, not only the page load.
- Check tags that fired and tags that did not fire.
- Confirm the data sent by the tag is what you expect.
Workspaces and versions
Workspaces help organize changes, while versions preserve a snapshot of what was published.
- A workspace can hold a set of draft changes.
- Publishing creates a container version.
- Version notes help future reviewers understand what changed.
- A previous version can help with recovery if a release causes a problem.
QA habits
Good tag QA is practical. It checks whether the tag fires in the right place, with the right trigger, and sends the right values.
- Avoid triggers that fire on broader actions than intended.
- Check consent and environment differences where relevant.
- Name tags and triggers so other people can understand them.
- Review changes before publishing to the live container.
