Preview Mode is Google Tag Manager’s testing mode for viewing which tags fire and why.
Example of Preview Mode
Tag Manager preview mode can show which trigger matched and which tags fired during a test submission. Use the evidence to diagnose configuration, then remember that preview success does not publish the workspace automatically.
Why Preview Mode matters
It matters because analytics turns marketing activity into decisions. Without clear measurement language, teams may misread performance, overvalue the wrong channels, or miss the actions that actually drive revenue.
