Section 9: Adding tags to Adobe PDF documents
Acrobat analyzes each page to determine the page's various elements and roles, their proper reading order, and which
tag to apply to each element. It then adds a tag tree to the document to represent these page elements and their
reading order. In Acrobat 7.0 Professional, a report of the results also appears in the How To window after the process
is complete, so that you can edit any tags that need repair.
Note: Recognizing the structure of complex documents can be very difficult for the tagging functionality in Acrobat. Pages
that contain elements such as closely spaced columns, irregular text alignment, noninteractive form fields, and tables
without borders may require considerable touchup using the features in Acrobat Professional and the instructions in
Sections 10 to 13 of this guide.
Reading the Add Tags Report
The Add Tags Report opens in the How To window after you tag a document in Acrobat 7.0 Professional. The report
lists potential errors by page, provides a navigational link to each error in the document, and offers suggestions for
fixing the errors.
You should assess the context of an error before following a particular suggestion for fixing it. For example, the report
might state that an element that has been tagged as a figure requires alternate text to make it accessible. When you
examine the figure in its context on the page, you may decide that the figure is a background design element instead
of a graphic that conveys valuable content to the user. If it's a nonessential figure, you would change the Figure tag
to a Background tag; if the figure is important for the reader, you would add the missing alternate text.
Note: The Add Tags Report highlights tagging-related problems only, and it is a temporary file that you cannot save. You
can assess other tagging, reading order, and accessibility problems by using an accessibility Full Check. This tool generates
a full accessibility report that you can save and refer to later. The accessibility Full Check is available in Acrobat Profes-
sional. See "Section 10: Evaluating Adobe PDF documents for accessibility problems" on page 52.
Use the links in the Add Tags Report to find potential problems that Acrobat Professional encountered during the tagging process.
