Cost per thousand impressions of an online ad. When an ad is served to a user, it’s counted as an impression. If an ad network charges you $1,000 for delivering 1 million impressions, your CPM is $1. A CPM model can be a good strategy if your campaign goal is to raise awareness of your brand. If your campaign goal is to increase user interaction with your brand or prompt users to take a specific action such as signing up for a loyalty program, a cost-per-click (CPC) model may be a better choice.
Whether you choose to do your marketing online or offline, one thing does not change. This is the concept that no single marketing strategy will be as effective as a combination of two or more marketing strategies.
