This practice not only enhances accessibility for users, including those using assistive technologies, but also facilitates indexing by search engines, which can result in better SEO performance. By using semantic HTML, developers can create more understandable and organized web pages, which in turn can contribute to a better user experience. In the context of various web development frameworks, the use of semantic HTML becomes even more relevant, as it allows components to be more descriptive and reusable, improving code maintainability and clarity. In summary, semantic HTML is a powerful tool for building modern and efficient web applications, aligning content with its real meaning and enhancing both accessibility and overall web page performance.

History: The concept of semantic HTML began to gain relevance with the introduction of HTML5 in 2008, which included new semantic tags designed to improve the structure of web content. Before this, developers often relied on generic tags, making it difficult for both browsers and search engines to understand the content. With HTML5, clearer standards were established that promoted the use of tags that reflect the meaning of the content, leading to an evolution in how web pages are built.

Uses: Semantic HTML is primarily used to enhance accessibility and search engine optimization (SEO). By employing tags that describe the content, it facilitates navigation and understanding for both users and assistive technologies. Additionally, it is common in the development of modern web applications, where a clear and maintainable code structure is sought.
