Cost per view (also known as CPV, cost per impression, or pay per impression) is a pricing model in digital advertising where advertisers pay for every time the ad is displayed. It is also known as pay per mille since advertisers pay for every 1,000 impressions rather than paying for every view.
It is one of the most popular pricing models. However, you have to be careful to make sure that it will not eat your budget aimlessly. When you pay per view, you can not be sure that the person will actually be interested or make a purchase. It is likely that you pay lots of money for views on websites with high traffic but will get only a very small percentage of conversions. Therefore, pay per impression needs big research of target audience and profitable channels.
Cost per view is often compared to pay per click advertising pricing model. Cost per view model is often chosen for building brand awareness. Cost per click model is for generating more leads and sales. You can also build brand awareness and pay for it less. This model is considered to be less financially risky but is also more expensive.
