CPM advertisers pay based on how often their ad is shown to users. For example, when you buy 10000 visits with a $2 CPM, youd end up paying $20 for the whole campaign. With CPC advertising, advertisers pay for actual visits to their site. For example, you may agree on $1.5 CPC and this is how much youll pay for every single click.
