Multimodal Content refers to content that incorporates multiple formats, such as text, images, audio, and video. As AI models become increasingly multimodal, they will be able to understand and process information from all these formats. This means that optimizing for AI search will require creating and structuring content in various modalities to appeal to the diverse sourcing preferences of different AI models. For example, a comprehensive strategy might include a blog post, an accompanying YouTube video, and an infographic to cover a single topic.
