- Scenario
- A user is editing an accessible PDF by adding new text to a newly inserted page, and is checking the reading order.
- Observed behavior
- The newly inserted page and its text are not automatically added to the document structure tree, causing the text to be absent from the Tags pane even after using the Reading Order tool.
Before modifying the structure tree of your PDF, save a backup copy of the document to ensure you do not lose any previously established accessibility formatting.
Manually Assign Text to the Document Structure Tree
Use the accessibility tools in your PDF editor to manually identify the untagged text and assign it to the proper reading structure.
When you add a new page or text block to an existing accessible PDF, the software may fail to link the new elements to the underlying structure tree. You must manually define how screen readers should interpret these elements.
Launch your PDF editor (such as Acrobat) and open the Accessibility toolset from the main tools menu.
Select the 'Reading Order' option to view how the current page elements are structured and identified.
Navigate to the newly added page and use your cursor to draw a box around or highlight the text that is missing from the Tags pane.
With the text selected, choose the appropriate tag type (such as 'Text/Paragraph' or 'Heading') from the Reading Order dialog box.
Open the Tags pane from the navigation panel to confirm the text is now accurately reflected in the structure tree.
Rebuild the Page from an Accessible Source
If the accessibility tools cannot recognize or tag the text, the PDF page structure may be corrupted, and rebuilding the page is the most effective workaround.

Frequently Asked Questions
What is the Tags pane in a PDF?
The Tags pane visually represents the logical structure of a PDF document. It organizes content into a tree-like hierarchy (headings, paragraphs, lists, tables), which is essential for assistive technologies like screen readers to navigate and read the file correctly.
What is the difference between the Content pane and the Tags pane?
The Content pane lists the physical objects (text, images, paths) exactly as they are drawn on the page, regardless of their meaning. The Tags pane provides the semantic meaning and logical reading order of those objects for accessibility purposes.
Why is it important to have tags in a PDF?
Tags make the PDF accessible to users with visual or cognitive disabilities. Without tags, a screen reader may read the document out of order, misinterpret tables, or skip over important content entirely.
Can I automatically add tags to an entire PDF?
Yes, many advanced PDF editors include an 'Autotag Document' feature that uses AI to analyze the layout and generate a structure tree automatically. However, manual review is usually still required to fix any misidentified elements.
