Page Headings

<h1>

All pages must have a unique H1 tag – this should be the main title for the piece of content. Only one H1 tag should exist on each page.

<h2>

and so on

For each subsection, H2 tags (and H3, H4, H5…) should be used. These provide additional signals about the specific content of the page and are arguably just as important as the H1. Multiple H2 (and so on) tags can exist within one document.
