What are advertising banners?
Banner advertising refers to the use of a perpendicular graphic display that extends across the top, bottom, or sides of a website or online media property.
The horizontal type of banner advertisement is called a leaderboard, while the vertical banners are called skyscrapers and are positioned on a page's sidebars.
Banner ads are image-based rather than text-based and are a popular form of online advertising. They are widely used to promote a brand and/or to entice visitors from a host website to visit the advertiser's website.
