Why Image SEO Matters

Images appear in Google Image Search, can rank in regular search, and affect page speed.

Image Optimization Basics

  • Compress files (WebP format recommended)
  • Use descriptive filenames
  • Add detailed alt text
  • Specify dimensions
  • Implement lazy loading

Alt Text Best Practices

Describe the image accurately and include relevant keywords naturally. Keep it under 125 characters.

Image Formats

WebP offers best compression. Use JPEG for photos, PNG for graphics with transparency.
