SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes assets (resource) and references (resource) components.

What problem does it solve?

This Skill helps you improve search visibility and page performance by auditing on-page images and optimizing them for better indexing, richer display, and faster loading.

Core Features & Use Cases

  • Image SEO audit: checks alt text quality, file size thresholds, formats, responsive markup (srcset/sizes), lazy-loading correctness, CLS prevention via dimensions, and LCP-related fetch/decoding guidance.
  • Image SERP analysis: when the DataForSEO MCP is available, cross-references page images against Google Images results to reveal competitor image patterns and opportunities.
  • Optimization pipeline: converts images to WebP/AVIF, injects IPTC/XMP metadata (where supported), generates responsive variants, and produces recommended AVIF > WebP > JPEG HTML patterns.
  • Use case: audit a product/category page for missing or weak alt text and oversized JPEGs, then convert and redeploy optimized image assets with compliant markup.

Quick Start

Run the skill against a target page URL to generate an image audit summary and a prioritized optimization list.

Frequently Asked Questions about seo-images

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I audit images for SEO and page performance issues?▼

Image SEO audits evaluate alt text quality, file sizes, formats, responsive markup (srcset/sizes), lazy-loading correctness, CLS prevention via dimensions, and LCP-related fetch/decoding guidance to improve search visibility and loading speed.

What is the best way to convert JPEG images to WebP or AVIF formats?▼

An optimization pipeline converts images to WebP/AVIF while preserving IPTC/XMP metadata, generates responsive variants, and produces recommended AVIF > WebP > JPEG HTML patterns for deployment.

How does lazy loading affect Core Web Vitals and image SEO?▼

Lazy loading correctness is evaluated alongside layout stability (CLS) prevention via dimensions and LCP-related fetch/decoding guidance to ensure optimized images load efficiently without shifting page elements.

Can I check if my page images are ranking in Google Images SERP?▼

When the DataForSEO MCP is available, page images are cross-referenced against Google Images results to reveal competitor image patterns and identify ranking opportunities.

Do I need structured media metadata like IPTC or XMP for image optimization?▼

IPTC/XMP metadata is injected during the optimization pipeline where supported, preserving embedded data through WebP/AVIF conversion to maintain structured media context for search indexing.
