Image alt text auditor
Find the images your page is not describing, for search or for a screen reader.
Free, instant, and nothing to sign up for.
This checked one thing. A full audit reads the whole site and tells you what to fix first.

- Every image on the page and whether it carries alt text
- Alt text that exceeds a sensible length
- Images correctly marked decorative, which need no description
- Tracking pixels and spacers, excluded rather than counted against you
Why it matters
Alt text is how a search engine knows what an image shows and how a blind visitor knows what they are missing. For a local business the first matters more than most people expect, because image search is a real route into a florist, a cafe or a builder. The accessibility half is not optional either: in Australia, web accessibility sits under the Disability Discrimination Act.
How to read the result
Missing alt text is the finding to act on. Alt text that is too long is a smaller problem and usually means a caption ended up in the wrong place. A clean result does not mean your alt text is good, only that it is present and a reasonable length: this tool cannot tell whether the description matches the picture. Read a few of your own and ask whether someone who could not see the image would learn anything.
Common questions
Should every image have alt text?
Every image that carries meaning. Purely decorative images should have an empty alt attribute, which tells a screen reader to skip them. An empty alt is a decision; a missing one is an omission.
How long should alt text be?
A short sentence. Describe what is in the image and why it is on the page. If you find yourself writing three lines, that content probably belongs in a caption where everyone can read it.
Does alt text help rankings?
It is how you rank in image search, and it gives the page a little more context. It is not a lever for ranking the page itself, and stuffing keywords into it has been a known negative signal for years.
