A Published LinkedIn Post Lost Its Accessibility Metadata: Restore Alt Text or Captions

Start with the live post URL and the approved publishing record. Identify the missing field before changing anything: image alt text, captions for spoken or meaningful audio, or both. Do not assume a visual description in the post copy replaces metadata. The affected viewer needs access to the meaning at the point they encounter the asset.

LinkedIn says it builds and tests products with assistive technology, including screen reading software, and has adopted WCAG 2.2 Level AA in its design and development work. That does not prove a specific post remains accessible after publishing. The post still needs a live check. LinkedIn accessibility (accessed October 16, 2026).

• Capture the live post URL, publication date, asset type, and the person responsible for the repair.
• Copy the approved alt text, caption file, transcript, creative brief, or approval record into the regression record.
• Record exactly what a viewer can no longer access before editing the live post.

Which approved accessibility metadata disappeared from the live post?

Compare the live post against the approved baseline field by field. For an image, look for the approved text alternative. For a video with spoken or other meaningful audio, check the available captions and whether they match the approved version. Do not label a change as a metadata loss if the original post never had approved metadata.

For an informative image, the text alternative should communicate the meaning or content shown visually, rather than merely list visible objects. W3C gives the same distinction in its guidance for informative images. W3C informative images guidance (accessed October 16, 2026).

Should you restore, replace, or withdraw the affected asset?

Restore the asset when the approved baseline still matches the live creative. This is the clean path for an unchanged image whose approved alt text vanished, or for a video whose approved captions can be put back without changing their meaning.

Replace the asset when the baseline is missing, the media has changed, or the original wording no longer communicates the current image or video. Write the new description from the purpose of the asset. W3C's decision tree says a meaningful simple image needs a brief description that conveys its meaning, while a decorative image can use an empty text alternative. W3C alt decision tree (accessed October 16, 2026).

Withdraw the asset when the team cannot restore or replace it promptly and cannot verify a usable live result. Keep the post copy only if it stands on its own and does not depend on the missing image or video for meaning. Otherwise, remove the post and publish a repaired version after review.

• Restore: approved metadata exists and still accurately describes the live asset.
• Replace: the asset or its intended meaning changed, but the team can create and approve a new accessible version.
• Withdraw: the missing information cannot be repaired and live verification is not possible.

How should you write replacement alt text for a LinkedIn image?

Write the information the image adds to the post. If the image contains text that is not already present nearby, include that text or its meaningful content. If a graphic makes a claim, gives an instruction, or shows a result, state that claim, instruction, or result in the text alternative or in nearby post copy.

Do not write a generic inventory such as "image of a chart" when the chart carries the point. W3C says complex information should also be available elsewhere on the page. On a LinkedIn post, put the chart's conclusion and relevant labels in the post text if the image cannot carry all of that information cleanly. W3C alt decision tree (accessed October 16, 2026).

• Describe the message the viewer needs, not every visual detail.
• Include image text when readers cannot get it elsewhere in the post.
• Keep names and claims out unless the approved creative or post copy supports them.

How should you repair captions on a LinkedIn video?

First decide whether the audio contains information needed to understand the video. When it does, captions need to cover spoken dialogue and meaningful non-speech audio. W3C describes captions as synchronized text for speech and the non-speech audio needed for understanding. W3C captions guidance (accessed October 16, 2026).

Automatic captions can be a starting point, not the final proof. W3C says automatically generated captions do not meet user needs or accessibility requirements unless they are confirmed fully accurate. Check names, terms, punctuation, timing, speaker labels when needed, and meaningful sounds before publishing the repaired video.

If the video conveys key visual information without saying it aloud, add that information in the post copy or replace the video with a version whose message is available to viewers who cannot see the visual detail.

What live retest proves the post is accessible again?

Retest the public, live post after the platform has saved the repair. An edit-screen preview proves only that the editor accepted the entry. The test should confirm that the live image exposes the intended text alternative, or that the live video makes accurate captions available and synchronized with the audio.

For captions, test against the asset itself. Section508.gov says captions should synchronize with the audio, include dialogue and important sounds, and remain visible long enough to read. Section 508 caption guidance (updated August 2025).

Use the same regression record to store the retest result. If a screen reader cannot expose the intended image meaning, or captions are absent, inaccurate, or out of sync, the repair is still open.

• Open the public post URL in a logged-out or separate browser session where practical.
• Test the image with a screen reader or have a qualified accessibility reviewer confirm the exposed text alternative.
• Play the full video with captions enabled and compare captions against the audible speech and meaningful sounds.
• Save the tester, date, live URL, result, and any follow-up decision in the regression record.

When should the team report the regression to LinkedIn?

Report a platform issue when the approved metadata is present in the editor but absent or unusable on the live post, or when the post cannot be repaired through normal publishing controls. Keep the report narrow: include the post URL, asset type, the expected accessible behavior, the actual behavior, and the live test evidence.

LinkedIn directs people who find an accessibility bug or have trouble using its products with assistive technology to its Disability Answer Desk. LinkedIn accessibility (accessed October 16, 2026). A platform report does not replace the team's duty to remove or replace inaccessible content while waiting for a response.
