An affiliate banner is a digital advertisement that promotes a product or service and is placed on a website or blog by an affiliate marketer. These banners typically contain eye-catching graphics and persuasive text to entice viewers to click on them and make a purchase. The affiliate marketer earns a commission for each sale made through the banner, making it a mutually beneficial partnership between the advertiser and the affiliate. Affiliate banners are a popular form of online marketing and can be found on various websites, from small blogs to large e-commerce platforms.
