How to Fix Text and Hyperlinks Marked as Artifacts in Accessible PDFs
Question details
The user needs to understand why text and hyperlinks exported from Adobe InDesign are being flagged as artifacts or failing tagged annotation checks in a PDF accessibility checker, despite proper paragraph style mappings.
- Product
- PDF / Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Running an accessibility check on a PDF document exported from Adobe InDesign.
- Observed behavior
- Text and hyperlinks are incorrectly flagged as artifacts or fail structured tagged annotation checks instead of being recognized as readable, tagged structural elements.
Before troubleshooting the tags, ensure you have access to the original InDesign source file, as correcting export settings at the root level is the most reliable way to fix persistent artifact errors.
Diagnose and Correct Tagging Issues in Acrobat and InDesign
The most effective way to resolve PDF artifact issues is to identify the missing or misconfigured tags in your PDF accessibility checker and explicitly correct the tagging hierarchy in your source software.
In accessible PDFs, an 'artifact' is typically a decorative element meant to be ignored by screen readers. When meaningful text or links are incorrectly classified as artifacts, it is usually because the PDF export process failed to generate the appropriate structural tags or nested them improperly.
Open your PDF in your accessibility tool (e.g., Acrobat Accessibility Checker). Run a full check to locate the exact error message for the failed tagged annotations and identify which specific elements are failing.
Open the Tags panel and the Content panel in your PDF software. Find the failing hyperlinks or text elements and check whether they are completely missing from the tag tree or incorrectly mislabeled as '<Artifact>'.
If hyperlinks are failing, check their properties. Ensure that the link annotation itself contains the necessary alternative text and is correctly placed within a valid '<Link>' structure element.
Return to your InDesign document. Open the Export Tagging menu (in Paragraph Styles) to ensure your styles are explicitly mapped to standard PDF tags. Avoid putting interactive elements on master pages, as they often export as artifacts by default.
Export the document again via 'File > Export'. In the export dialog, ensure the 'Create Tagged PDF' checkbox is selected. Open the new document and run the accessibility check again.

Frequently Asked Questions
What exactly is an artifact in a PDF?
An artifact is a graphical or textual element in a PDF that provides no meaningful content for understanding the document, such as page numbers, decorative lines, or background images. Screen readers and accessibility tools are designed to ignore artifacts.
Why are my valid hyperlinks read as artifacts?
This usually occurs if the PDF export engine fails to nest the link annotation inside a proper structural tag (like the <Link> tag), or if the hyperlink was placed on a Master Page in the source software, which automatically designates the content as a background artifact.
Can I manually fix PDF tags without going back to the source file?
Yes, advanced PDF editors feature a Tags panel where you can manually create structure elements, reassign text to tags, or change artifacts back to content. However, fixing the tagging structure in the original source document and re-exporting is strongly recommended to ensure accuracy and save time.
Does editing a PDF directly break its accessibility tags?
It can. Changing layout, text flow, or performing deep visual edits directly in a PDF environment may disrupt the underlying tag tree. This can occasionally cause the accessibility structure to detach from the text, turning the text into untagged artifacts.
