According to Google, an ad must be at least 50% visible for a second to count as an impression.
Fifty percent visible for one second.
So, I’m an advertiser and I run a :30 commercial.
Half of that commercial is visible – say top or bottom half – and viewed for one second. Which means 29 seconds are not viewed.
That’s an impression.
Google has more data than God and the data they’ll charge me for as an advertiser is this?
So whether 30 seconds of my commercial are watched, or just one second, the charge is the same.
I don’t know what people call this.
But it sure ain’t progress.
