During manual evaluation using a screen reader/ANDI, observe all of the elements on the page and ensure that every element has an accessible name and role which accurately describes its purpose.
A list of things to be on the lookout for include
Elements that behave like links (elements that take you to a different place) must be announced as links.
Elements that behave like buttons (elements that trigger functionality) must be announced as buttons.
Elements organized as a table must announce as a table
Related content items displayed together in a group (with or without bullets) must announce as a list (ordered or unordered depending on the context)
Any text input must be announced as an input.
"Announced as" in this case refers to how a screen reader will say for example "Link" or "Button" when the user navigates to them.
