VAST Tag Tester

Test your VAST tag in seconds

AdValify's VAST validator performs more than 36+ tests in a couple of seconds — much faster than you could ever have done manually.

Inspect VAST URLs and get a detailed quality assurance report. LUFS, bit rates, codecs, MOOV atoms and more.

Direct Playback

Did you know the MP4 format has a MOOV atom that acts like a table of contents? This table of contents has to be downloaded before playback can begin.

AdValify checks if the video is optimized for immediate playback, to avoid buffering/stalling and improve the user experience.

Check LUFS levels

Audio loudness is a typical issue with video ads. You don't want your ads to be too loud or too quiet.

AdValify tests if the loudness is at -24 LUFS, the industry standard commonly used for video ads.

Customizable Ad Specifications

Create customized ad specifications for each placement or ad type. Let ad quality scans pass/fail accordingly.

For example, when a creative is > 300KB or the load time is >1 second. Create different ad specs if you have multiple media channels.

Scan ads via the API

Leverage automation and scan millions of ads using the API. Get a detailed QA report in JSON format for your ad ops team.

Flag creatives that don't comply with your ad specs in your own system. Let Ad Ops double-check on failed scans only.
