Overview: Tags are invisible labels that give semantic meaning to the document. Tags help screen readers and other assistive technologies know what each element is. It could be a heading, an image, a paragraph, anything. They convey this information to users as tags, then users have the ability to easily navigate the document and understand its structure.

Section 4.1: How to Tag Manually
Tags are used in Adobe Acrobat to identify a contents value in a document so it can be read and interpreted by assistive technology. By tagging an object, we are assigning a hierarchical value to an element. For example: An <H1> tag is used for Headings Style 1 or the main heading for a section or chapter. <H2> is used for Heading Style 2, most commonly used for subsections. In a hierarchy, <H2> must be parented under <H1>. Paragraphs or <p>, but be parented under <H2> or in necessary order. Headings must always be higher than paragraphs.

Section 4.12: Container Tags
Container elements are the highest level of element and provide hierarchical grouping for other block-level elements. However, these tags do not convey any semantic meaning to the document. They are simply used to organize the tag tree structure and are more for the benefit of the document author than the end user. They will not be picked up or announced by screen readers, but they might be very helpful to find your way around in a long document.
