Image Optimization Analysis

When to Use

• Use when auditing image SEO, alt text, file sizes, formats, or lazy loading.
• Use when the user wants image-specific performance recommendations.
• Use when checking media quality signals that affect both SEO and Core Web Vitals.

Checks

Alt Text

• Present on all <img> elements (except decorative: role="presentation")
• Descriptive: describes the image content, not "image.jpg" or "photo"
• Includes relevant keywords where natural, not keyword-stuffed
• Length: 10-125 characters

Good examples:

• "Professional plumber repairing kitchen sink faucet"
• "Red 2024 Toyota Camry sedan front view"
• "Team meeting in modern office conference room"
