Heading tags should be used to structure a document by allowing a hierarchy of sub-sections. The correct use of Headings is to split a document up into relavent sections or paragraphs with a summarised heading.

Headings play a massive part in the accessibility of a web page. Screen readers (adaptive software) for blind and partially sighted people use them to jump to the different sections of a document so the page content can be assesed and the required information located quickly.

Heading structure example below:
