The dt tag marks the start of a term being defined and helps to establish a clear relationship between words and their meanings.

This enhances readability and allows search engines to better index your content, which can improve SEO. Using the dt tag promotes semantic HTML, aiding screen readers and other assistive technologies in providing context to users.
