SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Slow, poorly labeled, or unoptimized images can weaken SEO performance and reduce visibility in Google Images while harming Core Web Vitals.

Core Features & Use Cases

  • Alt text and image markup checks: Detect missing or low-quality alt text and identify common HTML issues that limit image understanding.
  • Performance-oriented optimization: Evaluate file size, formats, responsive image configuration, lazy loading behavior, fetch priority, and CLS prevention.
  • Image SERP and file optimization: Optionally analyze image SERP patterns via DataForSEO and provide practical recommendations for converting and optimizing image files (WebP/AVIF), including metadata handling (IPTC/XMP).

Quick Start

Ask the assistant to run the image optimization audit for the page URL you are analyzing by saying: "Run /seo images optimize https://example.com/product-page".
