What is First impression definition ?

In digital advertising context, the first impression refers to the first ad displayed to a web user on a website or ad network for a given period - most often a day or a visit session.

The first impression may be specifically used to deliver an intrusive ad format like a takeover ad or a pre-home interstitial - for more details see first impression takeover.

On ad exchanges with RTB processes, the first impression may be sought after by retargeting or data specialists. In this context, the first impression may be sold through private deals.
