Image Alt Text Checker

An Image Alt Text Checker inspects `alt` attributes on image elements and separates missing attributes from deliberately empty ones. It also flags unusually long alternative text for review. The goal is not to force descriptive text onto every image; decorative images often should use an empty alt attribute so assistive technologies can ignore them.

Alt text is primarily an accessibility feature and secondarily useful for image understanding. A blanket rule such as 'every image needs a keyword-rich alt' creates poor experiences. The useful audit is whether meaningful images have concise descriptions and decorative images are handled intentionally.

1. 1Enter the page URL.
2. 2Review images missing the alt attribute entirely.
3. 3Inspect empty alt values and decide whether those images are genuinely decorative.
4. 4Review very long alt text for unnecessary detail or keyword stuffing.
5. 5Fix the source component or CMS field so the improvement applies consistently.

• Missing alt means no alt attribute was present.
• `alt=""` can be correct for decorative images.
• A useful alt describes the image's purpose in the current context.
• Linked images may need an accessible name that helps users understand the destination.

• CMS leaves alt attribute out when the field is blank.
• Product images all use the same generic alt.
• Decorative icons receive verbose file-name descriptions.
• Alt text repeats nearby captions word for word without adding value.
• Keyword lists are inserted into alt attributes.

• Require meaningful alt input for content images where editors can provide it.
• Render empty alt for purely decorative images.
• Generate product-image alt from real product attributes carefully rather than generic templates.
• Review linked image accessibility separately from ordinary illustrations.

• Describe function and meaning, not every visual detail.
• Keep wording concise enough for practical screen-reader use.
• Do not start every alt with 'image of' unless the fact it is an image matters.
• Treat alt quality as editorial work rather than an SEO keyword field.

The checker can identify missing, empty and long values, but it cannot reliably judge whether a description communicates the right visual meaning. Human review is necessary.
