How this service works
Alt-text audit for any page: finds images with missing alt attributes, flags filename-as-alt and generic alt text, over-long alt, unlabeled svg[role=img], image-map areas and image inputs without alternatives. Counts decorative alt="" separately. For SEO and accessibility agents.
Output
Returns a structured report with total image count, count of images missing alt attributes, count of low-quality alt text (generic, filename-based, or over-long), a list of specific issues with details, and a separate count of decorative images using alt="".
Example use cases
Example prompt
“Can you audit https://example.com/about for alt text issues — I want to know which images are missing alt attributes, which have generic or filename-based alt text, and how many are decorative?”
Technical details
Endpoint
GEThttps://api.webbersites.com/api/seo/alt-checkWhen to prefer
Choose this endpoint when you specifically need image alt-text and accessibility metadata for a webpage, including nuanced checks for generic alt text, filenames used as alt, over-long descriptions, SVG roles, and image-map areas. Prefer over generic WCAG checkers when image accessibility is the primary concern, or when you need granular alt-text quality signals for SEO reporting.
Side effects
- URL is not publicly accessible or returns non-200 status — audit cannot be performed
- Page has no images — returns zeroed counts with empty issues array
- Malformed or non-HTTP URL input — returns validation error
- Page behind authentication or bot-blocking — content not retrievable
- Very large pages may time out or return partial results
