Image SEO
01 Definition
Image SEO meaning: The practice of optimizing images so they load fast and rank well in search results.
Image SEO covers the steps that help images perform in search and on the page. This includes descriptive file names, alt text, compressed file sizes, modern formats, and responsive sizing. Done well, it can improve page speed and image search visibility, though results depend on overall site quality and competition.

Why it matters
How Image SEO fits the work
Images often make up most of a page's weight, so optimizing them can speed up loading and open a second search channel through image results.
In context
After renaming files, adding alt text, and converting photos to WebP, a recipe blog cut its image weight by 60 percent and started appearing in image search.
Practical note
Compression helps speed, but avoid shrinking files so much that quality suffers. Always pair technical fixes with meaningful alt text and relevant, original images.
