Frequently asked questions
What does the Image SEO Analyzer audit?
Every image on the page: alt coverage, missing and duplicate alt text, format mix, and loading attributes. Tag-level only — it does not download the images.
Why does alt text matter?
Alt text tells search engines (and screen readers) what an image shows. Pages with missing alt text are harder to understand, and their images cannot rank in image search.
What counts as duplicate alt text?
The same alt text used on more than one image. Each image should describe what it actually shows — repeated alt text usually means a template default that was never filled in.
Does it download my images?
No. The audit is tag-level only: it reads the page’s HTML and reports on the img tags it finds, without downloading any image files.
