The headings test checks for appropriate use of headings in your page.

Why do we test for this?

Semantically correct content is good for search engine optimization and helps visitors without a visual browser access your content.

How do we test for this?

We check that you use headings in the right order (e.g. H1, then H2) and that no heading appears without a parent heading (i.e. you can't have a H2 without a H1).

What can I do about it?

Ensure that every page of your site uses headings in the right order, and that as a minimum, each has a H1.
