Headings
Headings are from a range of 1 through 6. Headings are the largest text on the screen, reserved for short, important text or numerals.
Overview
Headings help users and search engines to read and understand text. Headings also define which parts of your content are important, and show how they're interconnected
If you have an empty heading, a screen reader will alert the user that a heading is present, but it will not read out any text because there is none available to read. This may confuse users and could keep them from accessing the information on the page. If a user is navigating the contents of the page and they encounter an empty heading, they may move forward to the next heading in the list and could potentially miss entire sections of content.
Headings and subtitles
Subtitles are complementary to headings. They are typically reserved to give more context to a heading, they are only available underneath headings H1 and H2.
