What This Issue Means

This signal indicates that some images may not include meaningful alternative text.
When visual context is not described, screen reader users may miss information needed to complete tasks confidently.
Automated checks can detect missing or likely weak alt-text patterns and surface them for review.

Why It Matters

Image-heavy campaigns and product pages may lose clarity for users who depend on non-visual content.
Content teams may face last-minute remediation work before launch when alt-text quality is not reviewed early.
Inconsistent image descriptions can reduce conversion confidence on critical customer journeys.

How To Fix It

Add descriptive alt text to informative images, icons, and key visual assets that support user decisions.
Use empty alt text for decorative imagery that does not add content meaning.
Create editorial standards for recurring image types such as product cards, campaign banners, and infographics.

Common implementation mistakes

Using file names or generic labels like “image” as alt text.
Repeating nearby heading text instead of describing unique visual context.
Adding descriptive alt text to purely decorative graphics that should use empty alt text.

Manual Verification Checklist

Review templates with heavy imagery and confirm each informative image includes meaningful alt text.
Check icon-only controls and linked images to ensure names remain clear in assistive-technology output.
Run screen reader spot checks on high-traffic pages to verify image context is understandable.
Rerun automated checks after content updates.

Can automated checks validate alt-text quality?

Automated checks can detect missing or weak patterns, but manual review is recommended to verify whether text is meaningful for the journey.

Can AI help write alt text?

AI can speed up drafts, but teams should review final text for accuracy, brevity, and business relevance.
