CPM - total impressions or unique impressions??

[Anku31]

eCPM is is the estimated earning we would make on 1000 ad impressions.
But on my cpmfun reports page,there is a column for impressions & unique impressions.
My questions is,suppose my ecpm is $2,then would i earn $2 for a total of 1000 impressions or a total of 1000 'unique' impressions??

according to me total of 1000 'unique' impressions would be total unique user to your site and total of 1000 impressions is page views so it depends on the company how they pay u but normally CPM is based on page views
