Question: What's the difference between a podcast impression and a podcast interaction?
Answer:
Similar to impressions with a broadcast touchpoint, a podcast impression measures when the podcast is downloaded or when the podcast ad was dynamically inserted into a streaming podcast. A podcast interaction is recorded at the time that a consumer visits your website after being exposed to the podcast.
The viewer may listen to the podcast but never take any action. That would count as an impression. When the user clicks and comes to your website, it would be in interaction.
In the case of podcast, we have a 48 hour window after the ad airs aired where we check to see if someone visited the website or not.
