2. Design Elements: Effective banner design incorporates elements such as images, graphics, text, colors, typography, and sometimes animation or interactive features.

3. Size and Format: Banners come in various sizes and formats, including static images, animated GIFs, or HTML5 animations. The size and format are often determined by the platform or location where the banner will be displayed.

4. Message and Call to Action (CTA): Banners should have a clear and concise message, along with a compelling call to action that encourages viewers to take the desired step, such as clicking a link or making a purchase.

5. Visibility: Banners should be visually appealing and easy to read. They must stand out and catch the viewer's attention quickly.

6. Brand Consistency: Design elements should align with the brand's identity, ensuring that the banner maintains a cohesive look and reinforces brand recognition.

7. Responsive Design: In the context of web banners, it's essential to consider responsive design principles, ensuring that banners adapt to various screen sizes and devices.
