WCAG success criterion: "Information, structure, and relationships conveyed via the representation can be determined by software or is available in textual form."

Page contents are made accessible by headings.

The content structure of a page is divided by headings, among other things. Thanks to this structuring, users can get an overview of content, assign it to one another, and call it up in a targeted manner. To make this accessible to blind users, for example, HTML heading elements are an important prerequisite.

On the pages tested that are shown, heading level 1 (h1) was omitted, although there is no reason for this in terms of content. This can make orientation difficult for screen reader users, since an introductory heading to the content of the page is missing. For better comprehensibility of the page structure, heading levels should not be skipped or only skipped in terms of content. 

The heading structure is not logical in its whole, as there are empty headings (highlighted in yellow). Screen reader users can navigate directly to headings, but these headings are not read aloud, which can make orientation difficult.
