The first step to use graphic design to improve your content's SEO is to choose the right format for your content. Different formats have different advantages and disadvantages for SEO, depending on your goals, audience, and topic. For example, images can help you convey complex information, evoke emotions, and increase visual appeal, but they can also slow down your page loading speed, reduce readability, and require alt text for accessibility. Videos can help you demonstrate processes, showcase testimonials, and increase engagement, but they can also increase your bandwidth usage, distract from your main message, and require transcripts for indexing. Infographics can help you summarize data, highlight trends, and generate backlinks, but they can also be hard to design, difficult to update, and require supporting text for context. Therefore, you need to choose the format that best suits your content purpose, type, and length.
