Display advertising refers to visual online ads that appear as images, banners, or videos on websites and in apps. These ads can be displayed, for example, on the side of news pages, between articles, or within apps.
Display ads can be served based on browsing behavior, location, context, or past visits—unlike search engine advertising, which responds to an active search. Display ads are delivered through ad networks that aggregate numerous websites and apps and place ads where the defined target audience is active.
