How to Preview Creatives and Generate Ad Tags

Before anything goes live, you'll want to see the ad, share it, and pull its tag. All three happen in one place.

Preview a creative

Open Creatives and click any card or table row. The panel shows a live, playable preview — exactly what will serve, including video playback, social framing, and the QR code.

Creatives library

From the Overview tab you can also:

  • Copy a share link — a lightweight page anyone can open, no Spaceback login needed. Perfect for client review. Manage every link you've handed out from Manage labels & share links on the Creatives page.

  • View the original post the creative was built from.

Creative overview

Generate an ad tag

Open the Versions & Tags tab. Each version of the creative is a separate render with its own Campaign Manager ad tag — VAST for video, HTML5 for display.

Click Create tag to generate it, or Add ad tag for additional placements.

Versions & tags

Running dynamic text? Add {{variables}} (like {{city}}) to your copy in Ad Builder, save, and come back here to create per-value versions — full guide: DCO — Dynamic Text and Versions.

Debugging a tag

Something not firing right? Use the built-in Tag Validator (your name menu → Tag Validator). Paste a VAST URL, raw VAST XML, or an HTML/JS snippet and click Analyze — it traces the tag end-to-end, extracts every tracking pixel and video file, flags anything that looks off, and shows a safe preview of how it plays.
