Audit Image Alt Text Coverage

Image alt text serves dual purposes: it helps search engines understand what your images depict (boosting image search rankings) and provides descriptions for visually impaired users using screen readers. Missing alt text is both an SEO miss and an accessibility violation.

ToolRouter's audit_images skill scans all images on a page and checks for missing, empty, or generic alt text (like "image" or "photo"). It also checks for oversized images that could slow page load and missing dimension attributes that cause layout shift.

This audit is particularly important for e-commerce sites (product images drive shopping traffic), content sites with heavy image use, and any site that needs WCAG accessibility compliance.
