Your message needs to be instantly clear. Use concise, compelling copy that communicates your offer or value proposition in just a few words. Ensure your banner grabs attention quickly—users should understand the value in less than 5 seconds. Visuals are crucial in banner ads. High-quality images, contrasting colors, and bold fonts can make your banner stand out in a crowded space. Avoid cluttering the ad; a clean design with strong visuals is more effective.
