1.15 Multiple page landmarks with the same id (O)
1.15.1 WCAG 1.3.1 (A), 4.1.2 (A) - Desktop
Throughout the website, pages have multiple content information, navigation and region landmarks on the page which do not have unique labels..
Although it’s not a WCAG fail, it could make it difficult for users to differentiate between the different landmarks on the page and could cause confusion for screen reader users who navigate the site using landmarks.
1.15.2 Recommendation
Best practice is to add unique labelling for landmarks and further semantic markers on pages using HTML5 or WAI-ARIA roles and give further context to ensure that the purpose of each individual section is conveyed to users. This will help assistive technologies to understand the page structure and where each landmark sections start and end.
