Dacast Website Analytics Definitions and Metrics Glossary

Video analytics is a very powerful tool for broadcasters. They give broadcasters the ability to see how viewers are interacting and responding to their videos, which allows them to better tailor their content to connect with their target audience.

However, there is a bit of jargon used in many website analytics platforms, so not all terms used in the context of analytics are self-explanatory. 

This guide will explain the meaning of some common analytics-related video terminology that Dacast uses so you know exactly what data you’re looking at, as well as how it should be interpreted by the video analytics tool.

Dacast’s Glossary of Website Analytics Definitions

An “Impression” is when a video player loads but the content doesn’t start playing, usually because autoplay is off and the viewer could see the video but chose not to play it.
Every time when the video/web page is loaded is counted as an impression.

Play Time

The amount of time the content in question* was played; also expressed as an “Engagement by time(h)”
*Could be measured overall for the entire account in the Analytics section of the Account or per asset within the Analytics per each content asset’
