Image & visual search SEO

In one line

Image SEO optimises visuals so they rank in image search and are understood by visual tools, through descriptive filenames and alt text, compression, structured data, and surrounding context.

How to do it

  • Descriptive filenames and specific alt text (helps ranking and accessibility)
  • Compress and use modern formats (WebP/AVIF) for speed
  • Provide relevant surrounding text and captions for context
  • Add image structured data and include images in your sitemap
  • Use high-quality, original images where possible

Why it matters

Image search and visual tools (like Google Lens) drive real discovery, especially for products, recipes and how-tos. Well-labelled images also give AI engines context to understand and describe your visuals, and speed up your pages.
