Meaning
Impressions count specified occasions when a video representation is shown under a platform's measurement rules.
A practical example
A dashboard's thumbnail impressions may exclude some traffic surfaces, so they need not equal every time a link was seen.
What to check
Do not treat impressions as unique people or complete reach. Preserve the metric definition and reporting period when interpreting a campaign.
