Accessibility error If there's a hyperlink in the footer of a PDF (converted from word)
The Adobe help documentation does not cover an link annotation accessibility error If there's a hyperlink in the footer of a PDF (converted from word), as it happens because the link in the footer turns problematic annotation during PDF conversion rather than a normal body link.
Most common reasons i found were:
The footer is being treated as an artifact or decorative repeated content
If the footer is artifacted or tagged incorrectly in the PDF, Acrobat may flag the hyperlink because the link annotation exists but is not properly associated with the content.
Word sometimes exports footer text infragments, especially if different formatting is applied within the same footer. That can cause tagging errors or reading order issues.
A footer link may show up as a link visually, but the annotation is not nested properly under a Link tag in the tag tree.
Repeated links in headers and footers can create a large number of identical annotations. If even one converts badly, Acrobat may report an error.
The PDF was created in a way that strips or weakens accessibility structure
If someone used Printto PDF instead of Save As PDF or Export to PDF, links and tags often break.
