Image SEO Analyzer

Alt text, dimensions and loading behaviour for every image.

About the Image SEO Analyzer

Images without alt text are invisible to screen readers and image search; images without dimensions shift the layout as they load. The analyzer lists both and suggests lazy loading for offscreen images.

How it works

  • We fetch the URL from our server like a crawler: redirects are followed (up to five), private and internal addresses are refused, and large pages are capped.
  • The checks run on the live HTML and response headers. Nothing is guessed: every finding shows what we observed.
  • Results are not stored unless you are signed in, in which case they appear in your dashboard history.
