# SEO Images

> Image SEO audit for a URL or domain. Pulls raw image inventory via Firecrawl, then audits alt-text quality, modern-format coverage (WebP / AVIF), responsive sizing (srcset / sizes), lazy-loading and LCP signals (loading, fetchpriority, decoding), CLS-safe dimensions, descriptive file names, and ImageObject JSON-LD. Optional PageSpeed Insights cross-reference for real byte-saving estimates. Produces a prioritised remediation list plus paste-ready picture-element markup and ImageObject schema. Distinct from seo-technical-audit (which surfaces audit-flagged image issues at the site level) and from seo-schema (which generates page-level JSON-LD but not image-specific markup). Use when the user asks for "image SEO", "image audit", "alt-text audit", "WebP coverage", "AVIF", "responsive images", "lazy loading", "CLS images", "image schema", "ImageObject", "image rich results", "licensable images", or "optimise images".
