Preview Mode
Preview unpublished tags on your live site before publishing, with a signed one-hour preview link that works even for a container that has never been published.
Use this page to test Tag Manager changes on your live site before publishing. The dashboard Preview button loads your draft container instead of the published one, and the Chrome extension shows what each tag did while you test.
Preview unpublished tags
- In the tag manager, select Preview.
- In the Preview unpublished tags dialog, enter a URL on your site and select Open preview.
- The page opens with your draft container instead of the published one, and shows a Draft preview pill with an Exit button.
The preview link carries a private preview grant that lasts one hour and works for a container that has never been published. Preview tags can send real events, so point test traffic at a test destination when that matters.

Chrome extension
The Ours Privacy Chrome extension adds a Tag Manager panel to Chrome DevTools that shows what each tag did, the events the Web SDK sent, and an experiment builder. While a draft preview is active, the panel shows a Draft preview badge and reads from the draft container. Install and usage are on Chrome Extension.
Troubleshooting
- Preview link expired: links last one hour. Select Preview again for a fresh link.
- Published tags still running: the preview applies to the tab you opened from the link. Open the link again, or select Exit and start over.
Next steps
- Chrome Extension: see what each tag did while you test.
- Publishing and versions: take verified changes live.
- Tracking and debugging events: confirm events reached Ours Privacy.
