How to Review WordPress Image Alt Text with AI

Alt text cannot be judged from a filename or image alone. The same image may be informative in one context, decorative in another or functional when used as a link. AI can organize a review, but the decision must consider the rendered page and the purpose of the image.

Content work becomes safer when discovery, recommendation and editing remain separate stages. An assistant can organize evidence and prepare options quickly, but subject-matter accuracy, editorial ownership and publication approval remain human responsibilities.

In one sentence: Review each image in its page context, classify its role and draft candidate text only when a textual alternative is required.

What this guide helps you accomplish

The output should identify missing, empty, redundant, keyword-stuffed or contextually wrong alternatives and recommend the correct treatment. It must allow an empty alternative for decorative images and escalate complex images that need a longer description.

A useful result is not merely a polished answer. It must show which records or pages were examined, which evidence was unavailable, what the assistant inferred, what a human must decide and what actions remain prohibited.

What a successful output should contain

• A placement-level inventory, not only a media-library inventory.
• Image role: informative, decorative, functional, complex, text image or uncertain.
• Current alt value and issue classification.
• Candidate alternative text when appropriate.
• Need for a caption, nearby text or long description.
• Confidence and human review requirement.

Evidence and inputs to prepare

Media records may contain attachment metadata, but page context determines meaning. One attachment can appear in multiple locations with different purposes.

• WordPress media inventory with attachment ID, filename, title, caption, description and alt text.
• Pages or posts where each attachment is rendered.
• Surrounding headings, paragraphs and captions.
• Whether the image is inside a link or control and the destination or action.
• Image preview or real capture when visual content must be assessed.
• Language and locale of each placement.

Record the date, source, scope and known omissions for every input. Remove credentials, personal information and customer data that are not required for the task.

Classify the image before writing text

An informative image needs an equivalent description of its purpose in context. A decorative image generally needs an empty alt value. A functional image needs text describing the action or destination. Complex charts may need a concise alternative plus an adjacent detailed explanation.

Do not turn alt text into a keyword field

Google recommends useful, information-rich alternatives in context and warns against keyword stuffing. Accessibility remains the primary purpose. Repeating a filename, caption or surrounding sentence can also create unnecessary noise.

A safe workflow

1. Retrieve the complete media collection and verify pagination.
2. Map attachments to every rendered placement.
3. Capture page context, link purpose and current alternative text.
4. Classify the role of each placement.
5. Ask the assistant to flag issues and draft candidates only where appropriate.
6. Have an accessibility-aware reviewer inspect uncertain and complex cases.
7. Prepare a page-specific change list.
8. Apply approved changes separately.
9. Re-test rendered HTML and assistive experience.

The workflow intentionally separates analysis from implementation. A later change stage should reference the approved output rather than quietly expanding the permissions of the analytical identity.

Prompt recipe

Before using this prompt, replace every value in square brackets. Do not paste passwords, API keys, private customer records or unrelated personal information into the instruction.

Review the supplied WordPress image placements for alternative-text quality.

For each placement, return:
- Attachment ID, page URL and placement context
- Image role: informative, decorative, functional, complex, text image, or uncertain
- Current alt value
- Issue: missing, should be empty, redundant, inaccurate, keyword-stuffed, too long, wrong language, or none
- Candidate alt text when required
- Need for caption, nearby explanation or long description
- Confidence and human review note

Rules:
1. Judge the placement, not only the media record.
2. Do not create alt text for decorative images.
3. For linked images, describe the action or destination.
4. Do not repeat nearby text unnecessarily.
5. Do not edit WordPress.

Why this prompt is structured this way

The placement-level schema prevents a single attachment value from being treated as universally correct. Classification before generation also stops the assistant from filling every empty field with descriptive prose.

Recommended access boundary

Use a Read Only identity. The assistant may inspect the WordPress records included in scope, but attempts to create, edit, delete or publish content should be refused.

The workflow can affect public meaning, search interpretation, conversion or product information. Require explicit review before any change is applied.

What must remain outside this task

• No claim of WCAG conformance from this review.
• No generated description for an image the assistant cannot inspect.
• No keyword stuffing or duplication of nearby text.
• No assumption that an empty alt value is always an error.
• No media or page edit during the audit.

The access level is a starting recommendation, not a universal entitlement. The exact capabilities available to an identity must come from the installed product version and its published coverage.

How WP Agent Control fits

This is a general WordPress workflow, not a promise that Agent Control can edit every object or integration discussed here. For the guided path, start with public pages; plugin, theme, user, setting, file, deletion, WooCommerce, ACF and builder operations are not native guided tasks. Use separately qualified tools and permissions where required.

Get structured site information and inspect selected published pages after connecting. No temporary task is needed for this public reading. You can also browse public pages without the plugin; Agent Control adds structured access and a path toward authorized WordPress work.

Verification checklist

• ☐ Every finding identifies a page placement.
• ☐ Image role was classified before text was proposed.
• ☐ Decorative and functional cases use the correct treatment.
• ☐ Complex images are escalated for fuller explanation.
• ☐ Language and nearby text were considered.
• ☐ No WordPress media metadata changed.

Common failure modes

• Filename generation: Alt text is inferred from filenames without page context.
• Fill every blank: Decorative images receive unnecessary descriptions.
• SEO stuffing: Keywords replace a useful textual alternative.
• Media-level assumption: One attachment value is applied even though placements have different purposes.

Advanced note

A placement-aware accessibility ledger can keep the attachment ID, content ID, DOM context, classification, approved alternative and review date. This is more reliable than treating the media library’s single alt field as the full accessibility state of every use.
