Digital display advertising is a way of advertising on websites or apps. It uses images, videos, and other digital content to show ads. When you browse the internet, you might see ads appear on the screen. Companies pay for these ads to be shown to people who visit certain websites or use certain apps. These ads are designed to get people to buy or use their products or services. So when you see an ad, the company wants you to take action and visit their website, phone them, or buy their product or service.
