Using semantic HTML is primarily advantageous because it enhances accessibility and improves search engine optimization (SEO). By employing elements that clearly convey their meaning, such as `<article>`, `<section>`, `<header>`, and `<footer>`, developers can create a more meaningful structure for their web content. This helps assistive technologies, like screen readers, to interpret the content more effectively, making it accessible to individuals with disabilities.

Moreover, search engines can better understand the context of the content, which can lead to improved indexing and ranking of the page in search results. Such clarity in markup enables a richer experience for users and better communication of the page's purpose to both human users and automated systems.

The other options touch on aspects of web development but do not directly align with the fundamental purpose of semantic HTML. For instance, reducing the size of HTML documents, allowing for faster page loading, and simplifying CSS styling do not inherently relate to the semantic nature of the HTML elements themselves. These aspects may be impacted indirectly but are not the core benefits of using semantic markup.
