Online banners are digital advertisements that appear on websites, often at the top, bottom, or sides of a page. They can be in the form of images, animations, or even videos, designed to catch the attention of visitors. Advertisers use these banners to promote products, services, or events, encouraging users to click for more information. These banners are an essential part of online marketing strategies, as they help businesses reach a wider audience. By using targeted ads, companies can display their banners to specific groups of people based on their interests and online behavior, making them more effective in driving traffic to their websites.
