Observation Details
Main page function of form and display of tariff options has no separate heading and as such is grouped solely under main heading "Günstig ins Ausland telefonieren". As this is not a failure of this success criterion, the observation is marked Priority 5 – Best Practice. Consider evaluation of text content structure / outline. Heading structure is the most used navigation method for users of assistive technology on a given page. Heading structure might be used to guess existing page content. This might be done by checking the main outline first, getting main heading and structure of page by level 2 headings, which would result in the following list:
Günstig ins Ausland telefonieren
Alle Preisinformationen für Ihr Zielland
Häufig gestellte Fragen zum Telefonieren und SMS-Versenden ins Ausland
The user might navigate to "Alle Preisinformationen" first, skipping the intended main purpose content of the page. By giving the user explicit content structure, grouping all relevant content under at least a level 2 heading, keeping the base content below main heading level for introductory / descriptive content only, the user is more likely to (more easily or at all) find the important content.
