VAST Impression Logging Detector
Scan your VAST Video to determine if impressions are logged.
What is it?
Wether or not the VAST document has impression logging enabled.
Why is it important?
Impression logging is imperative in order to track how many VAST ads are served. Note that this doesn't necessarily mean the video has been played, as this is measured using the 'start' event tracker.
How to fix it?
Add an <Impression> element to the VAST => Ad => Inline branch.
