How to Troubleshoot Acrobat Reading Order and Tagging Problems
Question details
The user needs to fix empty accessibility tags and untagged content in Adobe Acrobat after interacting with the Tags and Reading Order panels.
- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Ensuring document accessibility by adjusting the reading order and properly assigning structural tags to PDF content.
- Observed behavior
- Accessibility tags remain empty or continue to display untagged content, and reading order adjustments do not accurately reflect the document structure.
Ensure you have the Accessibility tools enabled in your Acrobat workspace. It is highly recommended to save a backup copy of your PDF before applying any automated tagging or layout restructuring.
Use Autotag Document and Correct in the Order Panel
Run Acrobat's automatic tagging utility to generate an initial structure, then manually fix any out-of-order elements directly within the Order panel.
If the original source document lacked proper formatting, the automated results may be mediocre, but they generally provide a strong starting point by identifying lists, tables, and paragraphs.
Using the Order panel is the most efficient way to manually correct reading order. Changes made in the Order panel automatically reflect in the Tags panel, but the reverse is not always true.
Open the 'Accessibility' panel from the tools menu and click on the 'Autotag Document' utility to let Acrobat automatically detect and tag the document structure.
Navigate to the Tags panel, click on 'Options', and select 'Reading Order' to open the Order panel and Tags panel side-by-side.
In the Order panel, select and drag structural blocks to rearrange them into the correct logical reading order.
Use the Reading Order tool dialog box to retag items that were misidentified (such as reassigning H4 tags to standard H1 or body text as needed).

Frequently Asked Questions
Why do my PDF accessibility tags remain empty after using Autotag?
If your source document has a highly complex layout (such as those created in Adobe InDesign) or lacks basic formatting, the Autotag feature may struggle to recognize the content correctly. You will need to manually tag these elements using the Reading Order tool.
Should I edit tags in the Tags panel or the Order panel?
It is highly recommended to correct the reading order and retag items in the Order panel first. Any changes you make in the Order panel will automatically update the Tags panel, whereas changes made in the Tags panel do not consistently flow back to the Order panel.
Why does Acrobat assign incorrect heading levels like H4 to everything?
Acrobat's automated Autotag utility sometimes misinterprets standard text elements as specific heading levels (like H4) due to font sizes or styles in the source document. You can easily fix this by selecting the text in the Reading Order panel and tagging it as the correct heading level (e.g., Heading 1 or Body Text).
