The site impression is called a view or an ad view,  and its gave rise to a new set of companies called Ad networks and its a term that refers to the point in an ad is that view by a visitor or display on a web page.

In Web advertising, the term impression is sometimes used as a synonym for the view, as in ad view. Online publishers offer and their customers buy advertising tested in terms of ad views or impressions. Since a single Web page can contain multiple ads (depending on its design), a site usually registers more ad views per unit of time than Web pages per unit of time.

Impression sometimes called a view or an ad view, is a term that refers to the point in which an ad is viewed once by a visitor, or displayed once on a web page.
The number of impressions of a particular advertisement is determined by the number of times the particular page is located and loaded. If it is randomly generated, then it is the number of times the particular ad appears from the random generator.
An impression is an estimate of the number of people a particular advertisement is reaching, and may be counted in different ways depending upon the way the ad is situated on the page, as well as the number of times the web page where the ad appears is shown.
Ad reports list the number of total times of impression of the ad, which basically counts the number of times that the ad was served by the search engine when the keywords that the ad is connected to were searched for.

The amount of impressions is the amount of times that an advertisement has been shown (through Google AdWords or other forms of PPC advertising) or a webpage has been listed on a SERP (Search Engine Results Page, in the case of search engine optimization).

Note that the amount of impressions differs from the amount of times that an advertisement is actually seen. Impressions can be shown "under the fold". This means that visitors have to scroll down to be able to see the advertisement. This significantly increases the amount of advertisements that are never seen by a potential customer.

Within Google Adwords you are able to exclude impressions that are shown under the fold. This is often recommended by Google AdWords professionals, especially for CPM-campaigns.
