How VAST summary works

When you submit your VAST tag for validation, our system performs a deep analysis of every aspect of your VAST XML. We check for compliance with IAB standards, validate media files, verify tracking URLs, and analyze the structure of your tag. The results are presented in an easy-to-understand summary that highlights any issues found and provides clear recommendations for improvement.
