This is a paid form of advertising on websites. A banner takes the form of a square or rectangle and consists of graphic elements, text, images, and links leading to the advertiser's website. It is usually placed above or below side blocks, or on side panels, but can be positioned anywhere on the page. A banner can be either static, meaning unchanging, or dynamic, with moving elements. The traditional use of banners has now expanded into other forms, for example, they are used in advertisements on Facebook.
The main purpose of banner advertising is to draw attention to a specific product or service. It serves to increase website traffic and sales volume, inform about discounts or new products, and capture users' attention.
