Online display advertising is a great way to achieve the effects of print and television advertising, except without the high cost and risk. The approach is very similar to a PPC campaign except the ads consist of still images, animated images, and video. The advanced technologies behind these ads allow precise targeting/retargeting and the ability to constantly measure, analyze and optimize. Online display advertising is a great way to mitigate risk because poor performing ads can be identified quickly and discontinued; while ads with opportunity can be ramped up.
