Accessibility guidelines and standards may also require that visual labels be present.

Make sure that images in the document either have alternate text or, if decorative, are marked as artifacts. If this check fails, perform one of the following: Use the Tags panel to add alternate text for images in the PDF. Level A Figure Therefore, do not apply alternate text to elements with children unless the alternative text or actual text covers the content for these elements as well.
Alternative text is used to provide an alternative for images figures. Actual text is used to provide an alternative to text content. Associated with content: Make sure that alternate text is always an alternate representation for content on the page. If an element has alternate text, but does not contain any page content, there is no way to determine which page it is on. If the Screen Reader Option in the Reading preferences is not set to read the entire document, then screen readers never read the alternate text. Level A Hides annotation: Alternate text can not hide an annotation. This option checks for content other than figures that requires alternate text such as multimedia, annotation, or 3D models.
If an element has alternate text but does not contain any page content, there is no way to determine which page it is on. If additional description is required for the object beyond what can be provided in alternative text, provide a on-page description or link to a description of the non-text object. Level A Tables Because table structure can be complex, it is best practice to check them for accessibility manually. This check indicates whether a proper table structure exists.
To fix this issue, ensure that all acecssibility contain table header cells. To be accessible, tables must contain the same number of columns in each row, and rows in each column. To fix this checkeg, ensure that each table row has the same number of columns or the ColSpan and RowSpan properties of a cell are set properly to account for all cells in a row. Table summaries are optional unless the table data cannot be understood without it. Summaries can improve accessibility in complex acrobaf tables or when the way in which the data is read may be important. To fix this issue, provide a table summary for data tables where it is needed to make the data easier to understand, or to provide instructions on the data should be reviewed.
Level A Lists List items: This check reports whether each LI is a child of L tag. When this check fails, the structure of this list is incorrect. Lists must have the following structure: To fix this issue, ensure that all list item elements have a parent L tag. Level A Lbl and LBody: To fix the list structure, use the Tags panel to place Lbl and LBody elements under each list item. The list bullet or number should be a text node of the Lbl tag and the list item text a text node of the LBody tag. This rule checks nested headings.
When this check fails, headings are not nested properly. For example, a level 1 heading should precede a level 2 heading, etc. The Accessibility Checker is not able to determine when heading structures must be used—that must be determined by manually reviewing the document. To fix this issue, ensure that all heading levels are nested accordingly with no missing heading levels. Level A. The order of headings is not required under WCAG, and is only an advisory technique. Please consult with appropriate legal counsel for guidance on compliance with the referenced guidelines or any other accessibility guidelines.
Figure Successful Accessibility Check. Follow the same instructions as in the previous step.

However, rather than focusing specifically on headings, consider the overall structure. Are lists tagged as lists? Does content in appear in a reasonable order? In Step 3 you checked the read order of content, and may have rearranged some items so they would flow in a meaningful order in a small window. While this order is typically close to the order of items in the tag tree, the latter is the actual order in which items will be read by screen readers. If items seem to be out of order in the tag tree, drag them to a better location. Authoring tools generate a wide variety of tags.
As long as headings are tagged as headings; and lists, tables, and images are all tagged up appropriately, a document will likely be easy for screen reader users to navigate, read, and understand. In some cases, the tag tree of a document is a total mess, and it might be easier to delete all tags and start over building them from scratch rather than try to fix the existing tags. Step 6. Check for any lingering errors. Run the accessibility checker that is built in to Acrobat Pro. The report lists items in various categories such as Document, Page Content, etc.
