Image Optimization for SEO and Speed

Images are often the biggest performance drain. They’re also an SEO opportunity — alt text, file names, and structured data. Optimize both.

Format and Size

• WebP — Modern format. 25–35% smaller than JPEG. Use with JPEG fallback for older browsers.
• Dimensions — Serve the size you need. Don’t load 2000px for a 400px display.
• Compression — Quality 80–85 often looks fine. Test.

Lazy Loading

• Below the fold — Don’t load images until they’re near the viewport.
• Native lazy loading — loading="lazy" on img. Supported everywhere.
• Above the fold — Don’t lazy load. Hurts LCP.

SEO

• Alt text — Describe the image. “Industrial adhesive application on aluminum surface.” Not “image1.jpg.”
• File names — Descriptive. “epoxy-adhesive-spec-sheet.jpg” not “IMG_4823.jpg.”
