In short, the number of times people see your ad. In Web advertising, the term impression is sometimes used as a synonym for view, as in ad view.
Web sites sell advertising measured in terms of ad views or impressions.
The price is quoted in CPM, which means Cost Per Thousand. A CPM of 280 means 1,000 impressions at 280 Baht or 28 Satang per impression. When you buy a specified number of impressions and tell us when you want the campaign to start and stop, our state of the art ad management software ensures that your ads are evenly spread out over that period. For example, if you buy 30,000 impressions for one month, our ad management software will ensure that 1,000 impressions are delivered each day, no more, no less. Ask them for the number of times your ad will be seen in a month.
