When formatting information organize your layout using headings and subheadings. Screen readers move through by a reading order. Beginning with, Heading 1 to Heading 2 and so on. After there are no more headings the reading order will recognize paragraphs next, and the screen reader will let the viewer know they will listen to a paragraph. Breaking up information into smaller paragraphs will aid the viewer into finding information that are looking for faster, rather than listening to a long list or a long paragraph of information.
