When it comes to SEM, there are various banner ad formats you can use depending on your objectives, budget, and target audience. Static banner ads are simple and straightforward, displaying a single image and message. They’re easy to create and load quickly, but may not be as attention-grabbing as other formats. Animated banner ads use motion such as GIFs or HTML5 animations to create more dynamic visuals. They can showcase multiple messages or products, but may be expensive and time-consuming to produce. Interactive banner ads invite users to interact with them by clicking, hovering, or swiping. They can provide a more immersive and personalized experience or additional information or value, such as a quiz, game, video, or calculator. However, they require more technical skills and resources to create and may not be compatible with all platforms or formats.
