Display ads are, naturally, a form of advertising that uses visual elements such as images, videos, animations, or text to promote a product, service, or brand.
Display ads usually appear on websites, apps, and social media platforms.
Some of the main forms of display ads are banners, pop-ups, and sidebars. They could also be interstitial (full-screen ads appearing between content), video ads, rich media ads, etc.
Except for the well-known form people see every day on their smart devices, display ads can actually be both online and offline. Digital display ads are those seen online, such as banners, pop-ups, and video ads, while traditional display ads utilize physical spaces like billboards, flyers, or posters to reach audiences in the real world.
