Image optimization analysis for SEO and performance. Checks alt text, file sizes, formats, responsive images, lazy loading, CLS prevention, image SERP rankings (via DataForSEO), and image file optimization (WebP/AVIF conversion, IPTC/XMP metadata injection). Use when user says "image optimization", "alt text", "image SEO", "image size", "image audit", "optimize images", "image metadata", "image SERP", "convert to webp", or "image file optimize".

The seo-images skill is designed to analyze and improve image usage from both an SEO and performance perspective. It focuses on identifying common issues that can negatively impact search visibility, page speed, accessibility, and user experience. By evaluating how images are implemented on a webpage, it helps ensure that they are not only visually effective but also properly optimized for search engines and modern web performance standards.
This skill covers a wide range of technical checks including alt text quality, image file sizes across different categories (thumbnails, content images, and hero images), and modern image formats such as WebP, AVIF, JPEG, PNG, and SVG. It also evaluates whether responsive image techniques like srcset and sizes are used correctly, and whether lazy loading is implemented appropriately without harming critical rendering metrics such as Largest Contentful Paint (LCP). Additionally, it considers layout stability factors like CLS prevention, image search ranking signals via DataForSEO, and advanced optimizations such as IPTC/XMP metadata injection and image format conversion strategies.
Typical use cases include SEO audits, website performance optimization, e-commerce product image optimization, and accessibility improvements. It is especially useful for developers, SEO specialists, content teams, and technical auditors who need to ensure images contribute positively to both rankings and user experience. The skill helps bridge the gap between visual design and technical SEO requirements, ensuring images are efficient, descriptive, and properly structured for modern web environments.
It analyzes image-related SEO and performance factors such as alt text quality, file sizes, image formats, responsive image usage, lazy loading implementation, layout stability (CLS), and image optimization techniques including metadata and compression.
No. It is designed to work at the HTML and web asset level, so it is compatible with any website, CMS, or frontend framework as long as image elements are present in the markup.
No. While it identifies SEO best practices and technical improvements, actual search rankings depend on many external factors, including content quality, backlinks, and search engine algorithms.
Yes. It evaluates whether modern formats such as WebP and AVIF are used and recommends them where appropriate, while also considering fallback formats for broader browser compatibility.
Yes. The skill warns against lazy loading above-the-fold images because it can negatively impact performance metrics like LCP, even though lazy loading is beneficial for below-the-fold content.
