SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

It helps you find and fix image SEO and performance issues that hurt rankings and user experience, including missing alt text, oversized files, inefficient formats, and layout instability.

Core Features & Use Cases

  • On-page image audit: Detects missing or weak alt text, missing dimensions (CLS risk), wrong/lower-performance formats, absent responsive behavior (srcset/sizes), missing lazy-loading rules, and slow-to-load images (including LCP guidance).
  • Image file optimization guidance: Recommends converting to WebP/AVIF, compressing to category-based size thresholds, and improving filenames and CDN delivery patterns.
  • Image SERP analysis (optional): Cross-references on-page images with Google Images rankings via DataForSEO when available, identifying competitor patterns and opportunities.
  • Metadata optimization: Supports IPTC/XMP read/write workflows (for example, enriching image metadata using exiftool), plus metadata preservation checks after conversion.

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 fix missing alt text or CLS issues?▼

To audit images for SEO, you need to detect missing alt text, missing dimensions causing layout shift, and inefficient formats. This skill analyzes HTML markup to flag these issues and provides prioritized recommendations to improve indexability and page performance.

What is the best way to optimize images for web performance using WebP or AVIF conversion?▼

Optimizing images for web performance involves converting files to modern formats like WebP or AVIF and compressing them to category-based size thresholds. The skill evaluates your current formats and CDN delivery patterns to recommend specific compression and conversion actions.

How does responsive image markup with srcset and lazy loading affect my page speed?▼

Responsive image markup using srcset and lazy loading directly improves page speed by serving appropriately sized visuals and deferring offscreen image loads. The skill validates these responsive attributes and load behaviors to prevent slow LCP times and layout instability.

Can I analyze Google Images SERP rankings to find competitor image optimization opportunities?▼

You can analyze Google Images SERP rankings to identify competitor patterns by cross-referencing on-page visuals with DataForSEO data. The skill optionally integrates this SERP benchmarking to highlight ranking opportunities, falling back gracefully when external data is unavailable.

Do I need exiftool to preserve IPTC and XMP metadata during image conversion?▼

You need exiftool to read and write IPTC and XMP metadata if you want to enrich image metadata and ensure preservation after format conversion. The skill supports these workflows and performs metadata preservation checks to maintain your image SEO data.
