seo-imageslisted

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>` 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".

# Image SEO Audit A focused, page-level (or domain-sample) audit of every `<img>` and `<picture>` on the target. Surfaces alt-text issues, format gaps (WebP/AVIF coverage), responsive-image gaps (`srcset` / `sizes`), LCP and CLS risk, and missing `ImageObject` markup. Output is a prioritised remediation list plus paste-ready `<picture>` and JSON-LD snippets. > **Adapted from [`AgriciDaniel/claude-seo`](https://github.com/AgriciDaniel/claude-seo)'s `seo-images` skill** (MIT). Rubric, lazy-loader taxonomy, and severity ladder track the upstream implementation; data sources are wired to this catalogue's DataForSEO / Firecrawl / Google APIs stack. ## Prerequisites - **Required for inventory:** `mcp__firecrawl-mcp__firecrawl_scrape` (raw HTML access). `WebFetch` returns markdown only — every `<img>` attribute (`srcset`, `sizes`, `loading`, `fetchpriority`, `width`, `height`, `data-src*` lazy variants) is stripped before the skill ever sees it. Without Firecrawl the audit cannot run. Install via `bash extensions/firecrawl/install.sh`. - **DataForSEO MCP server connected** — used for the page set in domain mode (`mcp__dataforseo__dataforseo_labs_google_relevant_pages` for top traffic pages) and for `mcp__dataforseo__on_page_instant_pages` (returns the page's image resource list, cross-checking the Firecrawl inventory). - **Optional (PSI byte-saving estimates):** `google-api.json` configured (Tier 0 — API key only). When present, step 9 runs and adds real Lighthouse `wastedBytes`
