Proper content structure can be achieved by ensuring well-organized sitemaps and consistent URL structures, which help search engines understand the site's hierarchy and keywords. Fast loading times are also essential, which can be achieved by minifying assets, using responsive images, and optimizing mobile-friendliness. Additionally, enabling social sharing and using HTTPS can improve the site's visibility and credibility. By implementing these strategies, a JAMstack site can be optimized for SEO and provide a better user experience.
