I. What is a Web Banner? How is it Used?
A Web Banner, fully known as Website Banner, refers to images designed and utilized on websites for advertising, brand recognition, information dissemination, messaging, and other content delivery purposes directly on the homepage. Currently, Web Banners are popular in two main formats: Static Images or Animated Images.
Web Banners are now widely used for various purposes, generally serving the following roles:
- Homepage Web Banner: This is the largest image, positioned centrally on the homepage and considered a prime location because its content always impresses users and is immediately visible upon accessing the site.
- Top Web Banner: A horizontal image displayed at the top of the website, always visible alongside other content. This banner conveys messages and content for website owners and is displayed across all subpages.
- Side Web Banner: A vertical banner displayed alongside website content. This banner is crucial for designers and content creators.
- Bottom Web Banner: Also known as a footer banner, it is often used to add actionable information and increase user interaction on the website.
