If Acrobat encounters potential problems while running the Adds Tags To Document command, the Add Tags Report opens in the navigation pane. The report lists potential problems by page, provides a navigational link to each problem, and offers suggestions for fixing them.

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, not an illustration that conveys valuable meaning to the user. In the case of a nonessential image, you would change the Figure tag to a Background tag; in the case of an image intended to convey meaning to the reader, you would add the missing alternate text.
